American Wigeon Nov 01, 2024

The American Wigeon is a grazer. Its bill is narrow, with a pointed tip like that of a goose. When feeding on water plants, a wigeon grabs a leaf and rips it off with its strong bill, rather than using the straining apparatus typical of dabbling ducks. Take a field trip with your local Audubon and see if you can spot a wigeon.

Songbirds Teach Each Other Tricks Oct 31, 2024

In the UK for years, milk came in bottles with foil caps. Great Tits, a common songbird, learned how to peck through the foil. The skill spread. But how? Researchers trained Great Tits in different ways of opening a box and re-released them. Knowledge of how to open the box spread rapidly, with most birds copying the trained bird in their group. In a follow-up study, the researchers made one method of opening the box more effective. Many birds quickly switched to the better method, suggesting the tits can stand up to peer pressure if they see there’s a better way of doing things.

Birds in the Winter Garden Oct 30, 2024

Put your winter garden to work as a haven for birds. Leaves and brush left to compost provide foraging and roosting places, smother this year’s weeds, and feed next spring’s plant growth. Watch for juncos and towhees in the leaf litter and wrens in the brush. Maybe even a Song Sparrow! With a little planning, your garden can be a haven for birds year round.

Spark Bird: Chidi Paige and the Yellow Warbler Oct 29, 2024

When Chidi Paige moved from Nigeria to the U.S., she began running a youth STEM program and had to teach lessons on bird identification. She was in for a challenge: she had to learn the local bird species quickly. On a birding trip, she spotted a Yellow Warbler in a pine tree. The beautiful warbler got Chidi hooked on birding. She has designed several games to make learning bird identification fun for kids.

The Bustard and the Bee-eater Oct 27, 2024

The massive Kori Bustard struts across the savannahs of Eastern and Southern Africa. Its crested head sits on top of a long neck and stilted legs. And this winged giant has a colorful companion. A small bird called the Carmine Bee-eater perches on the bustard’s back. The Kori Bustard and the Carmine Bee-eater have a symbiotic relationship where at least one of them benefits. While the bustard searches for lizards, rodents, and other prey, it kicks up smaller insects that the bee-eater snatches up.

Meadowlarks and Grasslands Oct 26, 2024

The clear, whistled music of the Eastern Meadowlark (seen here) is the unmistakable anthem of eastern North America's farmlands and open country. The Western Meadowlark and its sweet, liquid notes epitomize the natural expanses of the American West. Sadly, birds of such grassy habitats are among the fastest declining species in North America. Learn more about these birds and efforts to conserve their habitats. The meadowlarks' best hope lies in the conservation of farmland and grassland. Learn more about the Conservation Reserve Program.

Hear White-throated Sparrows Learning to Sing Oct 25, 2024

The White-throated Sparrow’s melancholy whistle is hauntingly beautiful. But when you hear an adult sparrow performing, just know that the bird wasn’t always an expert singer. In the fall, listen for White-throated Sparrows rehearsing their song. Inexperienced young birds sometimes begin with disorganized jumbles of notes known as sub-songs. As winter deepens, the first-year birds begin to get the syllables of their songs down, but they might sound shaky and off-key. But by summer, hopefully, all the new adult birds will be virtuosos.

Flyin' in the Rain Oct 24, 2024

Most birds are mostly waterproof. Their feathers, aided by oil from preen glands, keep them pretty watertight. So why do birds avoid flying during rainstorms? It may have more to do with the air than with the water. Rainstorms tend to occur when atmospheric pressure is low. Air in a low-pressure system is less dense. But it’s dense air that gives birds the aerodynamic lift they need to take wing. Falling rain and high humidity make air even less dense. Many birds perch and wait out a storm. Afterward, birds once again take to the skies.

Banding Birds Oct 22, 2024

Willistown Conservation Trust in Pennsylvania carries out bird banding to help researchers understand bird populations. Led by licensed bird banders, a team of volunteers catches birds using mist nets — 8-foot tall nets made of fine nylon string that practically disappear when strung out between poles. After carefully untangling birds from the net, volunteers weigh and measure the birds, affixing a small metal band to their legs with a unique ID. Compiling records for many banded birds helps keep track of whole species.

Welcoming Back Winter Birds Oct 21, 2024

Although we may think of autumn as the end of the growing season, a sort of winding down in the natural world, for birds it’s as much a season of renewal as the spring. In the colder months, we welcome back our winter birds — juncos, swans, and more — which spent the summer in their breeding territories to the north. Offering the right kind of food and environment in the winter months can attract these migrants to your yard!

Cedar Waxwings - Sleek and Handsome Oct 20, 2024

When courting in spring, male and female Cedar Waxwings communicate with distinctly different calls and, perched side by side, often pass back and forth between them a berry or other small fruit or even a flower petal. Waxwings display a wealth of eye-catching plumage. If you relish the company of Cedar Waxwings, plant fruit-bearing trees and shrubs. Find native plants for your garden at Audubon's Native Plant Database.

Prairie Warblers - An Early Successional Species Oct 19, 2024

Despite their name, Prairie Warblers nest in tree farms of recently planted pines, in fields overgrown with scattered shrubs, and in clearings under power lines. Biologists call these “early successional” habitats. They’re characterized by plants that are the first to return to land altered by clearing or fire. Prairie Warblers and similar birds have declined rapidly during the last 50 years, being pressed from all sides. But they’re now benefiting from conservation on several fronts, including the Michael Huber Prairie Warbler Preserve in New Jersey’s Pine Barrens and the Albany Pine Bush Reserve in New York.

Sooty Tern Oct 17, 2024

Sooty Terns have long been called "wide-awakes" because of their calls. But it may describe their sleeping habits, too. When young terns leave their breeding grounds, they don't return for several years. They do not rest on the water, and only rarely land on floating objects. They feed while aloft, grabbing prey from the ocean's surface. On the fly, they also capture fish that have been chased out of the water by predators. In other words, Sooty Terns live in the air for years at a time.

The Sound of a Thousand Geese Taking Off at Once Oct 16, 2024

Komodo Dragons and Cockatoos Oct 15, 2024

Due to trapping for the pet trade, the talkative and showy Yellow-crested Cockatoo is now considered critically endangered. But scientists recently discovered a stronghold for the species: Komodo Island — yes, the one with the dragons. The Komodo population of Yellow-crested Cockatoos appears stable. The island has been an Indonesian national park since 1980. Park rangers may have helped deter poachers, but community support for conservation and the literal dragons have played a role, too.

All Those Fish in a Puffin's Beak Oct 14, 2024

Puffins fly under water into schools of slender fish, filling their large beaks. Fish are wedged into the gape, the stretchy skin at the beak hinge, but the bill edges still line up neatly. The dangling fish won’t slide out because the puffin’s tongue and roof of the mouth are heavily lined with backward-angled spines. When its beak is full, the adult flies back to its nest and feeds it all to a single chick.

Long, upward slopes called escarpments offer a good chance of seeing some of the many raptor species found in Belize. Shaped like a compact Red-tailed Hawk, White Hawks are white overall with black markings and scan the landscape for reptile prey. Bat Falcons have a darkly barred chest and cinnamon belly, and chase down swifts, dragonflies, and the bats that give them their name. Ornate Hawk-Eagles stand over two feet tall and are capable of catching monkeys.

Purple Martins Head South to the Amazon Oct 06, 2024

The Purple Martin is the largest swallow that nests in the US and Canada. During fall, Purple Martins from western North America migrate to a distinct wintering area in southeastern Brazil — a travel distance of more than 5,000 miles! Scientists believe that Purple Martins started out as a South American swallow species. Over time, they evolved a seasonal migration to North America because the longer days of summer sunlight provided extra hunting and feeding opportunities during nesting season.

Putting the Hum in Hummingbird Oct 04, 2024

To figure out the source of a hummingbird’s hum, scientists built a special rig to measure air pressure, twelve high-speed cameras, and over 2,000 microphones to observe hummingbirds fluttering in place at an artificial flower. The researchers found that the hum derives from the difference in air pressure between the top and bottom of the wings, which alternates forty times a second as the hummingbird flaps. The rapidly shifting air pressure produces a harmonic set of sounds, from low to high, creating that iconic, musical hum.

Migrations: Can Birds 'See' Magnetic Fields? Oct 03, 2024

Some migratory songbirds such as European Robins have special light-sensitive proteins called cryptochromes in their eyes. New research suggests how the cryptochromes could alter their behavior in the presence of magnetic fields, giving birds a visual cue for north and south. Other birds can navigate with the help of a mineral called magnetite in their beaks.

The Bird of Freedom Oct 01, 2024

There’s a bird in Cuba with plumage in blue, red and white — the same colors as the nation’s flag. The Tocororo, or Cuban Trogon, is the national bird of Cuba. When the Tocororo is kept in a cage, they often die. This fact has become a metaphor of freedom embraced by Cubans. The Cuban Trogon is a medium-sized bird often found in pairs. Its song sounds like its Spanish name, “Tocororo.” While el Tocororo is currently abundant, its population is declining due to loss of habitat.

Glowing Feathers Sep 30, 2024

When a Northern Saw-whet Owl spreads its wings, many birds can see something our human eyes can’t: the owl’s flight feathers glow with ultraviolet light. It’s invisible to humans without the help of a UV blacklight. While the glowing feathers on parrots might help them attract mates, the reason for the owls’ glowing feathers still isn’t clear. However, scientists realized that they could estimate an owl’s age based on the pattern of luminescent color on the wings, which changes predictably as birds grow and replace their feathers.

Great Horned Owl Family in Autumn Sep 29, 2024

Compared to many birds, Great Horned Owls remain with their parents a long time. They hatched in early March, from eggs laid in late January. By April, both parents were hunting through the night to feed their young. But for the last two weeks, the adults have not fed the young. The owlets have learned the skills they need to hunt for themselves. And any night now, the young owls will strike out on their own.

Fairy-Wrens Sing Secret Passwords to Unborn Chicks Sep 26, 2024

Superb Fairy-wrens teach their embryonic chicks a secret code. This incubation call contains a special note that will later serve as a password. When the chicks have hatched, this password enables the adult birds to identify their babies in the darkness of their domed nest. A species of Australian cuckoo lays its eggs in the wren’s nest, hoping to pawn off the task of parenting. But wren chicks learn their mother’s song and incorporate the password note into their begging calls.

The Eurasian Tree Sparrow Sep 25, 2024

In Lafayette Park in St. Louis, Missouri, a dozen or so Eurasian Tree Sparrows from Germany were released. But unlike other introduced species such as the similar-looking House Sparrow, they did not spread very far and remained in a limited area in the Midwest. It’s not fully clear why, but it’s possible that they just behave differently. And the aggressive House Sparrow may have helped prevent the tree sparrows from spreading further by competing for the same nesting sites.

Prions Filter-Feed Like Whales Sep 21, 2024

Birds called prions have an especially creative approach to getting their food. They pass seawater through their mouths and filter it to catch tiny animals such as krill and other small crustaceans. It’s similar to how baleen whales feed, leading to the prion’s nickname: the whale-bird. The sides of their bills have comb-like structures. Small food items get trapped in the combs as water flows past. In Greek, the word “prion” means saw, which refers to the bird’s highly specialized mouth.

Migrations: You're Going the Wrong Way! Sep 18, 2024

During migration, some birds change orientation, often by a full 180 degrees, and travel almost the same distance — but in the opposite direction — as the rest of their species. The phenomenon is called misorientation. First-year birds are particularly susceptible. Many vagrant birds never find their way back on course, but some do, getting more comfortable with the route each year.

Seabirds in the Desert Sep 15, 2024

The White-vented Storm-Petrel is a small black and white seabird found off the coasts of Chile and Peru. Storm-petrels spend their entire lives at sea, except when nesting. Scientists had long been mystified about just where this species nests. A search lasting eight years led them to a site 50 miles inland in the Atacama desert, a place often compared to the surface of Mars. They employed dogs specially trained to sniff out seabirds. The dogs helped locate White-vented Storm-Petrel nests tucked into mineral deposits deep in the desert.

Cowbird Mafia Sep 14, 2024

Brown-headed Cowbirds have a sneaky approach to parenthood. They lay eggs in the nests of other songbirds, and the songbird hosts often raise the cowbird chick as their own. It’s called nest parasitism. But sometimes the hosts throw out the odd-looking egg. And when that happens, the cowbirds sometimes retaliate by destroying the hosts’ other eggs. Scientists call this “mafia behavior,” likening it to organized crime groups enforcing their demands on unwilling business partners.

Playful Keas Sep 13, 2024

Keas are large alpine parrots from New Zealand. Intelligent and social, they have olive-green plumage, a red rump, and a long, curved beak. Keas produce a distinct warbling call, a “play call,” that sounds — and functions — much like a human’s contagious laughter. Scientists made recordings of captive Keas making warbling calls, then played them for wild Keas. They began playing harder and even engaged birds that hadn’t been playing. Hearing it seemed to put them in a playful mood, even when they were alone.

The Women Who Fought the Feather Fad Sep 12, 2024

In the late 19th and early 20th centuries, the human fascination with bird feathers went a little too far. Women’s hats and dresses featured extravagant feathers from birds both near and far. The trade in feathers drove several species, from the Little Egret to the Great Crested Grebe, to near-extinction. Fed up with the killing of wild birds for fashion, a group of British women met to put an end to this cruelty. The organization became the Royal Society for the Protection of Birds, or RSPB, which continues to be a leader in bird conservation today.

The Surprising Secret of Hummingbird Tongues Sep 11, 2024

Hummingbirds use their long tongues to sip nectar from flowers. They’re able to roll their tongues into a tube-like shape. Since the 1800s, scientists thought those tongues worked through capillary action, like how water instantly rises into a straw in a full cup. But when scientists spent years using slow-motion cameras to capture hummingbirds drinking in greater detail, they uncovered a completely different story: the tongues act like a tiny but powerful pump.

Spark Bird: Walter and Patch Sep 10, 2024

Sculptor and musician Walter Kitundu first became enraptured by birds in 2005 when a Red-tailed Hawk flew four feet above his head. He named the bird Patch, after the white patch on the back of her head, and kept returning to the park to see her. Patch became used to Walter, accepting him as part of the landscape. He documented her transition from juvenile to adult, learning her quirks and mannerisms.

Birds as Pollinators Sep 09, 2024

Birds are part of the complex web of Nature, and each fits into this web in its own way. Some even pollinate flowers! While feeding at a flower, this Rainbow Lorikeet gets pollen on its forehead and throat. When it visits another flower of the same species, it transfers the pollen to that flower. The pollen fertilizes the plant's eggs to produce its seeds, and the plant's reproduction is assured.

Ridgway's Rails on San Francisco Bay Sep 08, 2024

Once abundant around San Francisco Bay, the Ridgway’s Rail — formerly known as the California Clapper Rail — is now endangered. In the 19th Century, unregulated hunting plundered the species. In the 20th Century, rampant development reduced salt marsh habitat by 85%. But in the 21st Century, the Ridgway’s Rail has allies. Restoration is under way to increase healthy saltmarsh habitat for these endangered birds. Also, efforts to control the number of predatory cats are improving the chances for the Ridgway’s Rail to survive.

Truffle-Hunting Birds Sep 07, 2024

With their excellent sense of smell, pigs are renowned for sniffing out truffles, a fungus that grows underground and is prized for its taste. But it turns out that some bird species can also find their way to a truffle treat. Researchers working in the Patagonia region of Chile had noticed truffles with little beak-sized bite marks, and even watched a bird eat a truffle. They found truffle DNA in the birds’ droppings, suggesting that truffles are a staple of the birds’ diet. Some of the fungi species eaten by the Patagonian birds look like berries that grow locally, which might help birds see them better.

Are Birds Nests Reused? Sep 06, 2024

Let’s talk about nests. Every spring, robins build their cup-shaped nests using grass and mud. Orioles weave a hanging sack. It’s hard work, and yet once the chicks fledge, the structures probably won’t be reused. But bigger birds, such as herons, hawks, and eagles, often reuse a nest for many years. Europe’s migratory White Storks — like those pictured here — get the award for best reuse. One nest site, still used in 1930 and likely seeing many repairs, dated back to 1549. That’s a continuous series of stork pairs nesting in one spot for 381 years!

The Secret Lives of Goldfinches Sep 05, 2024

American Goldfinches are one of our most familiar birds, but they lead lives that are anything but ordinary. These birds will sometimes raise two broods a year, have a secret weapon against cowbirds, and have the ability to distinguish between songs that — to our ears — sound the same. Backyard birds they may be, but American Goldfinches never cease to amaze.

Migration: Long, Short, and In-Between Sep 03, 2024

In September, this Arctic Tern flies from Alaska all the way to Antarctica. Rufous Hummingbirds follow pathways of mountain wildflowers, from as far north as Alaska south to Mexico. Ruby-crowned Kinglets, migrate altitudinally from the mountains to the lowlands. Each of these birds migrates, but on a very different course. All make the most of food and breeding opportunities that change with the seasons.

Can Crows Laugh at Me? Sep 02, 2024

The American Crow’s rattle call is uncommon, and researchers aren’t sure what it means. It could be a gathering call, a predator alarm, or a call between mates. But if you hear it, you might think it sounds like cackling laughter. However, no one has identified a crow noise that indicates glee at the expense of another creature. It’s just a coincidence that the rattle sounds like a laugh. However, crows can play pranks on other animals: egging on cats to fight and yanking on dog tails for their own amusement. They aren’t pranking for survival — as far as we can tell, it’s just for fun.

Does a Robin Hear Its Worm? Sep 01, 2024

How does a robin know a worm is in one exact spot? Does it see the worm or hear it? Smell it? Sense its movements through its feet? To find the answer, researchers buried worms in soil in a tray. They covered the soil with a thin but opaque sheet of cardboard, followed by more soil, so the robin couldn’t see the worms. Still, the robin found them with ease. The scientists concluded the birds are listening for their prey. There’s always more to learn about birds!

Catching Insects Aug 31, 2024

Birds that depend on flies for food have many creative ways of catching their prey. Swallows execute sharp turns and quick changes of speed. Bluebirds watch from a perch, pouncing when the time is right. A Chuck-will’s-widow flies with its scoop-like mouth wide open, engulfing moths and other insects. A Merlin snares dragonflies in its talons. Hummingbirds dart into swarms of midges.

Warning Eggs About a Warming World Aug 30, 2024

For birds, learning starts early. Birds listen to their parents’ songs and calls from inside the egg. Recent findings have shown that calls from Zebra Finch parents can even prepare their chicks for warmer temperatures before they hatch. Researchers noticed that Zebra Finches make a special high-pitched call, called a heat call, when sitting on their eggs on hot days. Once out of the egg, chicks whose parents made heat calls grow more slowly in the heat. As adults, they seek out warmer spots for their nests, and even produce more offspring of their own than finches that didn’t slow their growth in hot conditions when they were chicks.

Migrations: Molt Migration Aug 29, 2024

At the end of summer, the once-bright feathers of a male American Goldfinch look ragged. Growing new flight feathers in a process called molting makes him more vulnerable to predators. Before migrating to wintering grounds, many songbirds stop at a secondary location to undergo the indignities of molting. It’s called molt migration. The places birds go to molt could be important targets for conservation efforts.

Do Woodpeckers Suffer Brain Injuries? Aug 28, 2024

When woodpeckers drum, they slam their beaks against bark many times per second. Scientists have long hypothesized that woodpeckers have a way of protecting their brains from injury. However, more recent work provides a different picture. High-speed cameras showed scientists that woodpeckers aren’t softening the impacts to their skulls. And researchers also have found signs of cellular damage in woodpecker brains. However, woodpeckers could be protecting themselves in other ways, and may even have ways of repairing damage over time.

Wood Ducks Succeed Aug 27, 2024

Your eye may be drawn to the gorgeous male Wood Duck, but it is the call of the modestly plumaged female you’ll hear. This call tells the male where his mate is, important as the pair stays together through much of the winter and spring. Wood Ducks are among a small number of North American waterfowl that nest in cavities, and many of them nest in boxes we provide for them.

The Broad-tailed Hummingbird’s Dazzling Dives Aug 26, 2024

Broad-tailed Hummingbirds are small but hardy creatures built for life in the mountains. They survive freezing cold nights by slowing their heart rate and metabolism. And they perform a death-defying stunt for potential mates. Male Broad-tailed Hummingbirds begin their performance by flying up 60 feet or more in the air. Then they dive toward the earth, reaching speeds of up to 50 miles per hour! At the last moment, they pull out of their dive and fly horizontally past the female they’re trying to impress.

Swallow or Swift? Aug 25, 2024

At a glance, swallows and swifts, both graceful fliers, look much alike. But swifts — like this Chimney Swift — have longer, slimmer wings and short bodies, enabling them to glide for long periods. Their glides are punctuated by rapid, stiff bursts of wing-beats. Swallows, on the other hand, flex and flap their wings. Why do swifts have such a peculiar, stiff wing stroke? Picture a bird wing, with two halves jointed in the middle. Swift wings have a short inner “half” and a long outer half. This causes the stiffness.

What’s a Beak Made Of? Aug 24, 2024

Bird beaks, or bills, come in many shapes and sizes. And birds use them for just about everything: to collect food, preen, fight, court (as this pair of Laysan Albatrosses is doing), chop holes in trees, weave nests, and more. In order for a bird to fly, its beak must weigh as little as possible. Beaks are covered with a sheath of a tough material called keratin, which grows continuously because a beak wears down with use.

The Northern Mockingbird isn’t the only mimic bird in town. Brown Thrashers also learn songs from nearby birds and add them to their repertoire. The species has been documented singing over 1,100 different songs: a mix of imitations and invented little melodies. While mockingbirds usually repeat a song or phrase three or more times before moving on, Brown Thrashers tend to repeat a phrase only twice.

The Ulūlu's Comeback Aug 21, 2024

There are promising signs that a native Hawaiian bird called the ulūlu is on the way to recovery. Also known as the Millerbird, this small gray songbird nearly disappeared when invasive species including rabbits destroyed most of their habitats on the island of Laysan in the early 1900s. In the 2010s, biologists brought 50 individuals from the Nihoa population and reintroduced them to Laysan. From these humble beginnings, the population grew steadily, now sustaining itself at several hundred individuals.

A slim, sleek bird with a spiky crest, Phainopepla comes from the Greek for “shining cloak.” The name refers to the male’s glistening, inky black feathers, which are set off by piercing red eyes. And if the Greek name isn’t helping you picture it, a common nickname might: the goth cardinal. From February to April, they nest in pairs in the arid Sonoran Desert. From May to July, they form nesting colonies in leafy oak and sycamore canyons to escape the summer heat.

Turkey Vulture - Sky Sailor Aug 18, 2024

Although some of the Turkey Vulture's habits may evoke our disgust, these remarkable birds also inspire our awe. With wingspans approaching six feet, Turkey Vultures ride currents of air to make their spring and fall journeys, and to cover the miles of their home range in summer. Gliding on updrafts, or pushed along by weather fronts, Turkey Vultures rarely need to flap their wings more than ten times in a row. To rise above storms, they ride upward on thermals.

Hovering with Horned Larks Aug 16, 2024

Horned Larks rival meadowlarks as the most colorful birds of North American grasslands. They live in prairies, fields, and tundra, but agriculture and development now intrude on many of the Horned Lark's traditional nesting areas. The farmland Conservation Reserve Program encourages agricultural landowners to plant resource-conserving vegetation. This practice protects topsoil and provides habitat for birds like the Horned Lark, as well as other wildlife.

Making a Home Among the Saguaros Aug 14, 2024

In the arid Arizona desert, where cacti thrive but trees are scarce, the Gila Woodpecker and Gilded Flicker carve out nest cavities in living saguaros. Tall, old saguaros may be pocked with twenty or more nest holes, bearing witness to decades of woodpecker families. The woodpeckers excavate a new nest every year, leaving the old, now-empty cavities behind. But they don't stay empty for long. Elf Owls, Ferruginous Pygmy-Owls, Purple Martins, and Brown-crested Flycatchers all find the slightly used woodpecker cavities superb nest sites.

Buff-breasted Sandpiper Aug 11, 2024

A male Buff-breasted Sandpiper courts a female on their breeding grounds far north of the Arctic Circle. He raises his wings, flashing their silvery-white undersides, as he sings his clicking serenade. These birds spend much of the year on grasslands in Argentina, migrating to the Arctic in late spring. In the lower 48, September is a good time to look for this long-distance traveler. During migration, they show a distinct preference for grassy expanses such as pastures and rice fields. Purchasing organic rice can help secure the future of a threatened species like the Buff-breasted Sandpiper.

Migration and Fat Aug 10, 2024

If long migratory flights are amazing, what goes on inside a bird’s body during those flights seems absolutely astonishing. To store fat, birds may eat three times as much and forage over many more hours than normal, as they prepare for long-distance travel. Blackpoll Warblers double their weight in the lead-up to migration. Wilson’s Phalaropes may put on so much fat that they actually have to lose weight to get their fat-loaded bodies into the air. Some birds may need a long running start to take off!

Though half the size of a robin, the Carolina Wren has a powerful singing voice that seems to come from a much bigger bird. Many people remember their song with the phrase, “teakettle-teakettle-teakettle!” When these secretive birds venture into the open, look for their cocked tail, bright white eyebrows, tan breasts, and golden-brown backs. One reason these wrens thrive in cityscapes is their ability to build a nest in creative places: everything from an old boot to a window flower box to an engine block are potential places to raise their brood.

Protecting Endangered Birds from Maui’s Wildfires Aug 08, 2024

The Maui Bird Conservation Center helps care for Hawai‘i’s critically endangered bird species, some of which have gone extinct in the wild. Jennifer Pribble, the center’s Wildlife Care Supervisor, lives onsite. A year ago, several wildfires broke out on Maui island in Hawai‘i, killing over a hundred people. The first fire likely began in the forest near the bird center, as security footage later showed. Early in the morning, the wind began directing the fire toward the bird center. Jennifer and a neighbor rushed out to hold off the flames until firefighters arrived, helping save the lives of the center’s rare birds.

Bringing Birding Adventures to Broward County Aug 05, 2024

While Sierra Taliaferro was working as a Naturalist in Broward County, Florida, in 2021, she collaborated with Broward County Library to help enhance the public’s knowledge about birding. More people became interested in birding as a safe outdoor activity during the pandemic. Sierra and others designed birding backpacks with field guides and binoculars that could be checked out at 10 libraries throughout the county. Sierra also gave a webinar crash course on how to find birds. The program was a success, with many people checking out the backpacks and creating their own birding adventures.

An Amazing World of Owls Aug 04, 2024

Owls are magnificent animals that share our cities with us, and live in some of the most extreme environments on Earth. They range in size from huge, like the Blakiston’s Fish-Owl of Eastern Asia, to the songbird-sized Elf Owl, weighing less than half a deck of cards. Owls play key roles in their ecosystems and even help control pests such as non-native rodents. By giving these amazing birds their space when they’re nesting, preserving habitats where they breed and hunt, and avoiding rodenticides that could poison their prey, we can help ensure a safe future for our world’s incredible owls.

Pigeon Flocks Follow the Leader Aug 03, 2024

The flocking movements of homing pigeons are governed by a pecking order. Higher-ranked birds have more influence over how the flock moves. Leading birds change directions first, and followers swiftly copy the leader's movements. And birds at the front of the flock tend to make the navigational decisions. In other words, the pigeons follow the leader. Or leaders.

For Shorebirds, Summer Ends Early Aug 02, 2024

We often think of birds migrating south in the fall. But many species kick off their big trips surprisingly early in the year. Shorebirds nesting in the Arctic tundra are an extreme example. Birds like the American Golden-Plover have a small window of time to build a nest, find a mate, and lay eggs in the short Arctic growing season. Golden-plovers actually leave their juvenile young behind to begin flying south in mid-summer. The juveniles find their own way to South America later in the year!

Gannets and Dolphins Aug 01, 2024

Northern Gannets, fish-eating seabirds, dive headfirst into the ocean at speeds of up to 60 miles an hour, pursuing their prey. Sometimes, they get help. Dolphins herd fish into dense, frantic concentrations near the surface, while gannets take advantage and plunge into the shoals from aloft. Scientists call this a multi-species feeding association, a frequent phenomenon on the ocean’s surface. This may seem like evidence of cooperation between species, but it’s more about opportunity. Kittiwakes and gulls, as well as seals and whales, may join in, too.

Precision Flight in Flocks: How Does It Work? Jul 31, 2024

A flock of shorebirds flying wingtip to wingtip seems to act like a single organism, rolling and twisting in exquisite patterns. Flocks like these use a combination of two organizational patterns. One is a “cluster”: lots of birds flying together in a loose, three-dimensional cloud. The second is a basic V-formation, where smaller groups of birds within the flock sync up in V-shapes, like migrating geese. Voilà! Predator avoidance and aerodynamic efficiency.

Birds in Art Through the Ages Jul 30, 2024

Birds were one of the earliest subjects for human artists. A cave painting in France over 30,000 years old shows the unmistakable outline of an owl. Paintings on Ancient Egyptian palaces and tombs feature birds with intricately detailed flight feathers, colors, and postures, allowing researchers to identify the species thousands of years later.

Having Your Tail Scared Off Jul 29, 2024

When a hawk is about to capture a songbird, the songbird has one last trick: a fright molt. It’s when a bird loses feathers due to sudden stress. This usually involves feathers near the tail or rump, where they’re most likely to be attacked as they flee. It can be a saving grace when the bird is about to be caught — similar to a lizard dropping its tail. There’s a downside to having your tail scared off. A tail helps the bird turn and balance in flight. But if dropping feathers lets the bird live to chirp another day, it’s worth it.

To Mob or Not to Mob Jul 27, 2024

When a bird of prey flies over, a flock of crows may dive-bomb the predator and give it a noisy escort out of town. An Eastern Kingbird, like this one, will clamp its feet onto the back of a hawk to send it packing. How do they know which birds to chase off and which to ignore? By genetic wiring, or instinct, but also learning. By watching their parents in the act of mobbing, youngsters gain critical knowledge that may save their own skin.

Which Bird Has the Most Feathers Jul 26, 2024

In general, the bigger the bird, the higher the number of feathers. Someone counted the feathers on a Tundra Swan and came up with 25,216. At least 80% were on the swan’s neck. Penguins, on the other hand, have lots of small feathers all over their bodies. The largest species is the Emperor Penguin, and one project counted around 80,000 feathers on a single bird. That’s nearly sixty per square inch – keeping the penguin insulated and waterproof in harsh climates. But the most feathered creature ever? It may have been a dinosaur!

Black-necked Stilt – The Bird with Outrageous Legs Jul 24, 2024

Visit a shallow wetland in summer, and you might see this slender, black-and-white shorebird with outrageous red legs. The Black-necked Stilt uses its long legs for wading as it feeds on tiny insects and crustaceans on the surface of the water. Stilts are sensitive to drought, which has increased with global climate change. But they readily move to new breeding areas and respond quickly when new wetlands are created.

Shorebirds Aren't Always on the Shore Jul 21, 2024

Shorebirds' lives take them to many places other than the shore. Most of the shorebirds we see along our coasts migrate to the Arctic in summer. Here, many nest on the tundra, some along rushing streams, and others on rocky mountainsides. Long-billed Curlews winter on the Florida, Gulf, and Pacific coasts. But this one was seen in a field near Creston, BC, Canada, nearly 500 miles from the coast and 1/2 mile from the nearest body of water, the Kootenay River!

Australia's Rainforest Birds Jul 20, 2024

The rainforests of Eastern and Northeastern Australia harbor many species of birds found almost nowhere else. This Eastern Whipbird — which is more often heard than seen — hangs out in the dense understory. Easier to lay eyes on is the large, pigeon-like Wompoo Fruit-Dove. Feathered in a stunning combination of green, purple, and yellow, this bird is clearly named for its voice. And a pig-like grunting on the forest floor tells us we’re in the company of the Southern Cassowary. Its helmet — called a casque — makes it look as much like a dinosaur as any living bird.

Flying and Molting - A Tricky Balance Jul 16, 2024

Feathers are amazing structures. But after about a year, constant use and exposure to the elements mean they have to be replaced. So how do you replace the roughly 20 feathers in each wing that are essential to flight? Many species — such as this Common Raven — molt just a few feathers at a time so they can still fly. But waterbirds like ducks and loons molt all of their flight feathers at once. As a result, they’re earthbound and vulnerable to predators for a month or more — until their full suite of feathers has been completely restored.

How Birds Can Help Coral Reefs Recover Jul 15, 2024

Today kicks off Coral Reef Awareness Week. Coral reefs are hotspots of biodiversity, but they’re threatened by warming ocean temperatures, pollution, and overfishing. One thing to be aware of this week is how these underwater ecosystems are linked to birds in the skies above them. And seabirds that nest near coral reefs are a great source of nutrients that can help coral reefs recover faster from bleaching caused by oceanic heat waves.

Kestrels Love Nest Boxes Jul 14, 2024

This American Kestrel evolved to nest in tree cavities or small caves in cliffs. We humans have made life difficult for kestrels. Development has shrunk the open spaces they need. We’ve cleared away dead trees they rely on for nests and sprayed pesticides that eliminate the insects the birds eat. But we humans are also in a position to help. Volunteers are helping to build and put up nest boxes, improve habitat, and monitor these cool little falcons. Together, we can #BringBirdsBack.

A movie runs at 24 frames per second, just right for humans to sense as normal speed. Pigeons process the visual world several times faster. The frantic car chase that puts us at the edge of our seats would likely appear — to a pigeon — more like a slideshow or PowerPoint. A bird’s rapid-fire perception is vital to its staying alive, whether it’s hunting fast-moving prey or eluding speedy predators. From the pigeon’s perspective, humans live in the slow lane.

What's Inside a Woodpecker's Nest Hole? Jul 11, 2024

Many woodpeckers chisel out deep cavities in tree trunks in order to lay their eggs and raise their brood. The cavities hollowed out by the birds vary in size, depending on the species of woodpecker. The chamber of a tiny Downy Woodpecker descends about a foot from the opening, while the Pileated Woodpecker may chip out a chamber two feet deep. Both are beyond the reach of a pesky raccoon.

Most North American woodpeckers carve a new nest cavity each spring.

Rock Climbing Among the Peregrines Jul 09, 2024

Eagle Cliff in New Hampshire’s Franconia Notch State Park is an important nesting site for Peregrine Falcons. Each year, popular climbing routes in the area close temporarily to give nesting falcons their space. After peregrines disappeared from the northeast due to the pesticide DDT, Eagle Cliff was the first natural rock face to host a successful peregrine nest. Now, state agencies and New Hampshire Audubon work with rock climbing groups to decide when to close cliffs in the summer.

Polite Birds Gesture 'After You' with Their Wings Jul 08, 2024

Researchers studying birds called Japanese Tits, relatives of the chickadees and titmice in North America, noticed that mates raising chicks together often fluttered their wings near the entrance of their nest box. After recording hundreds of examples of this behavior, it became clear that the wing-flutter was a signal for the other bird to enter first, much like that arm-sweeping gesture that people use to mean, “after you.”

Spider Silk - Duct Tape for Bird Nests Jul 07, 2024

The spider’s web is an intricate piece of precision engineering. Made from large proteins, it’s sticky, stretchy, and tough. So it’s no surprise that many small birds — including this Anna’s Hummingbird — make a point of collecting strands of spider silk to use in nest construction. Spider silk not only acts as a glue, holding the nest together, but it’s flexible enough to accommodate the growing bodies of nestlings. And it’s resilient enough to withstand the bustle of raising those hungry babies.

The Marsh Wren's Many Nests Jul 04, 2024

Tiny Marsh Wrens live in wetlands, usually within cattails, reeds, or bulrushes. After choosing his territory, the male weaves up to 15 dome-shaped shells, lashing together cattails, grasses, or reeds. These are called "courting" nests. Then, sitting high atop a perch in the marsh, he sings, inviting a female to select a nest in his territory. once the female has chosen one of his shells, she lines it with cattail down, feathers, leaves, or grass and lays her eggs. Sometimes a second female chooses a nest on the opposite end of his territory.

As singers go, American Robins are exceptional. They’re often the first birds to sing in the morning, and the last you’ll hear in the evening. While their average song strings fewer than a dozen short phrases together and lasts only a few seconds, robins sometimes sing for minutes without a pause. But the most extraordinary measure of robin song is its variety.

If you’re new to birding, you might be baffled by names like Couch’s Kingbird, Wilson’s Warbler, and Townsend’s Solitaire. These birds were named in honor of scientists and their friends long ago. But the result is a long list of birds named after white men, many of whom took part in colonizing the Americas or enslaved people. The American Ornithological Society or AOS, which governs official bird names in English, is working to rename all birds named after people in North America.

Evolution on islands can produce unusually large species. Haast’s Eagle lived on the islands now known as New Zealand. With a wingspan of 9 feet and weighing up to 30 pounds, the eagle hunted the moa — a flightless bird that stood over ten feet tall. The eagles probably vanished not long after their moa prey went extinct, about 500 to 600 years ago. A site called the Cave of the Eagle contains Maori paintings of Haast’s Eagles, preserving the legacy of this immense raptor.

Raising baby birds is a lot of work. You might think that after seeing off their fledged young ones, bird parents would call it a day. But a surprising number of species start again and raise another set of young in the same breeding season — what’s called double brooding. Some birds squeeze in even more broods each year. Mourning Doves have been seen trying to raise six clutches of eggs in one season!

In grasslands of the central U.S., birds called Dickcissels sing a quirky song that “spells out” the syllables of their name. Dickcissels are approachable birds, often chirping away while a person walks nearby. But they’re also masters of concealment, hiding their nests from predators in tufts of grass and leafy wildflowers. Dickcissel populations have fallen by 30 percent since the 1960s. Yet the birds persist in searching for places to breed — nesting along roadsides, in pastures, and even in alfalfa fields.

The crocodilians — crocodiles and their relatives, like the American Alligator — are the closest living relatives of birds. About 250 million years ago, the ancestors of all crocodiles split off from the dinosaur group that gave rise to modern birds. While crocs these days are mostly short-legged ambush predators, before mass extinction there were ocean-dwelling crocodilians and even species that ran around on two legs.

American Golden-Plover Lays Claim to the Tundra Jun 17, 2024

A male American Golden-Plover proclaims its nesting territory with an aerial display known as the "butterfly flight." After flying up 50 feet, the plover switches to slow motion, raising its wings languidly until the wingtips nearly touch over its body, then lowering them gradually until they almost touch below – all the while calling. The plover sustains these slow and exaggerated wing-beats for nearly a minute – hanging in the air like an enormous butterfly.

Spark Bird: Nick Belardes and the Vermilion Flycatcher Jun 16, 2024

Author Nick Belardes was walking at a park near his home in San Luis Obispo, California, when he saw a man who seemed in tune with birds. Belardes asked him what the coolest bird around was, and the man replied Vermilion Flycatcher. Belardes and his wife soon went out looking for the ruby-like bird, finally spotting it through rain and mist. He remembers that sighting as a turning point that drew him deeper into the world of birds.

Northern Hawk Owl Jun 15, 2024

The Northern Hawk Owl is one of the least studied and least known of all birds in North America. Northern Hawk Owls are owls, but they share several traits with hawks and falcons: A streamlined body shape, daytime hunting habits, and stiff wing feathers for daytime hunting. (Owls that hunt at night have soft edges on their wing feathers, so they can hunt without making a sound.) No fossil relatives of the Northern Hawk Owl have yet been found, and it is the only living member of its genus. Which only adds to its allure.

All Those Colorful Orioles Jun 14, 2024

The Baltimore Oriole is a standout bird. With adult males’ electric orange and jet black feathers, and females and immature birds in various shades of yellow and orange, it’s no surprise that these birds show up in art, illustrations, and on the uniforms of Baltimore's baseball team. But they’re not the only orioles worth knowing. Orioles in the Americas belong to the blackbird family — and there are many of them. In this episode, meet a few of them!

Flickers and Buffleheads Jun 13, 2024

After a Northern Flicker carves out a nest cavity, chances are the birds will use the cavity for just one nesting season. But the cavity may have a prolonged career as a home for small owls, bluebirds, swallows, and other birds – including the Bufflehead. Buffleheads are the only ducks small enough to use the cavities of flickers. Clear-cutting in some northern forests has reduced nesting habitat for flickers and Buffleheads alike. Both benefit when consumers choose paper products made from recycled paper.

Studying Climate Change by Watching Bird Nests Jun 12, 2024

Organized by the Cornell Lab of Ornithology and by Birds Canada, volunteers for Project NestWatch observe local nesting birds and track whether they’re successful in raising their young. Because the nest-watching volunteers monitor birds over a huge area, they cover way more ground than a small team of scientists ever could. Data from Project NestWatch helped scientists reveal that cold snaps and heat waves make many bird parents less successful in raising their young.

Have You Ever Seen a Pink Gull? Jun 11, 2024

Some gulls and terns may show a glowing pink color, similar to that of flamingos and spoonbills. This pink color comes from pigments in the birds' food called carotenoids. These gulls and terns are able to convert these naturally occurring pigments to hues that may enhance their success at attracting a mate.

Common Nighthawks at the Ballgame Jun 10, 2024

An evening baseball game isn’t the only thing illuminated by the bright stadium lights. High in the air, countless flying insects are drawn to them. And those insects are a perfect snack for the game’s avian attendees! Common Nighthawks swoop with their wide mouths open to hoover up the flying insects under the lights, performing aerial stunts over the athletes on the ground.

City Hawks Versus Country Hawks Jun 09, 2024

Resident Cooper’s Hawks that nest in the urban areas of Albuquerque, New Mexico, are thriving as the populations of doves, their prey, have exploded. The easy prey gives the urban birds a competitive advantage over hawks in more natural habitats, where prey is less concentrated. The soaring numbers of urban Cooper's Hawks could help preserve the genetic diversity of the species far into the future.

Surviving Hail Storms Jun 08, 2024

As it began to hail, Marlon Inniss saw several Canada Geese doing something odd. Rather than trying to shield their heads, the geese pointed their bills skyward, directly into the path of the hail. The geese were pointing the smallest surface area of their sensitive bills, the narrow tip, into the hail — minimizing the impact. Inniss’s video of the behavior helped reaffirm an observation made by naturalist Aldo Leopold one hundred years before of Northern Pintails adopting the same stance.

Setting the Thermostat with Birds in Mind Jun 07, 2024

If you’ve already done things around the home with birds in mind, consider one more action that might be less obvious. Turning the thermostat down a degree or two in the colder months and up a degree in the warmer months might seem more about personal preference or energy bills than birds. But climate change is a grave threat to birds, putting two-thirds of North American bird species at risk of extinction. So anything that decreases carbon emissions is a step towards a better future for birds — not to mention people.

Three Brown Thrushes Jun 06, 2024

The Swainson's Thrush, the Hermit Thrush, and this Veery are small, brown birds, but their songs clearly distinguish them. The Swainson's Thrush announces its presence in early spring with subtle, limpid "whit" or "wink" sounds. Many rate it among the finest singers. A Veery's phrases tend downward in pitch. The Hermit Thrush sings ethereal, paired phrases, long flute-like notes backed by complex, reedy phrases.

Emily Raboteau on New York City's Bird Murals Jun 03, 2024

Emily Raboteau’s book, Lessons for Survival, begins with a painting of two Burrowing Owls on the security gate of a local business in West Harlem, near where she teaches. Intrigued, she found more bird murals nearby, later learning that they are part of a collaborative effort between the National Audubon Society and artists to highlight bird species at risk of extinction due to climate change. Emily decided to seek out all the murals and photograph them before they disappear – because like birds, street art is ephemeral.

Migrations: Tiny Bird, Epic Journey Jun 02, 2024

In the spring, Rufous Hummingbirds journey from Mexico to the northwest U.S., some as far north as Alaska! That’s almost 1,000 miles one way for a bird measuring just under four inches beak to tail, making this the longest migration of any bird relative to body length. Not long after arriving, they bulk up on nectar and bugs for the scenic return trip over the Rocky Mountains.

Deja Perkins on Gaps in Bird Observations May 31, 2024

For her PhD, Deja Perkins is studying datasets generated by the public, also known as participatory science projects. These projects include eBird, a site where anyone can upload bird observations. And they’re essential to conservation efforts. But Deja says that not every area is well represented in eBird, because right now the participants are predominantly white and affluent, leading to a gap in what we know about the diversity of birds in many low-income and minority areas. Involving a wide variety of people in reporting bird observations where they live could help close the data gaps and reveal where to put new green spaces for both birds and people.

Spark Bird: Dara Wilson and the Blue-gray Tanager May 30, 2024

While Dara Wilson was working at the Smithsonian’s National Zoo in D.C., she introduced visitors to the Amazonia exhibit. She would describe the song of a bird she’d never had the chance to see in the wild, the Blue-gray Tanager. But when Dara moved to Panama, she heard the song that she knew by heart already. Encountering the Blue-gray Tanager in its natural habitat inspired her to keep learning about birds — and to share that knowledge with others as an educator. Dara helps organize Black Birders Week.

What the Niagara River Means to Birds and People May 28, 2024

This episode narrated by Marcus Rosten explores the history and the birdlife of the Niagara River Corridor. Just downstream from the falls, Long-tailed Ducks and Bonaparte’s Gulls call out near the site where the Haudenosaunee and other Native American groups would portage around the falls. Niagara’s churning rapids prevent ice from forming, making it a year-round fishing spot for half the world’s species of gulls. The rapids were also the final hurdle for Freedom Seekers on the Underground Railroad journeying to Canada.

Celebrating Female Bird DayEducating people on female bird ID. May 25, 2024

In 2019, several co-workers at the National Audubon Society formed a team for the World Series of Birding that focused on identifying female birds. Called the Galbatrosses, they sought to highlight how female birds have been understudied and unfairly written off as quieter and less interesting. Since then, the Galbatrosses have led events about IDing female birds and held the first Female Bird Day over Memorial Day weekend in 2020. Learn how to participate in this year’s Female Bird Day here.

Saving Snags for Red-headed Woodpeckers May 24, 2024

Red-headed Woodpeckers excavate cavities in large, dead trees called snags. Yet, over much of the Red-head's range, snags are frequently cut down as unsightly, or because they make good firewood. There are ways we can help the Red-headed Woodpecker -- and many other woodpeckers, too. The key is to leave snags intact. If you must cut down a tree on your property, consider leaving the lower trunk as a snag. It's like a wildlife condominium!

In the meantime, consider creating a nestbox for a woodpecker. Find a link to instructions here!

Night Voices – Nightjars May 23, 2024

As darkness descends on a May evening, the voices of many birds go quiet. But for some birds, especially those known as nightjars, the music is just beginning! An Eastern Whip-poor-will shouts out its name. The call of a Common Poorwill echoes across a canyon. A Common Pauraque calls from the thorn scrub. A Buff-collared Nightjar repeats its Spanish nickname, Tucuchillo. And a Chuck-will’s-widow like this one calls from a woodland.

In this episode of BirdNoir, Private Eye Michael Stein gives a word of advice to Ollie, an up-and-coming gumshoe. Ollie thinks he has heard his first Gray Catbird, a species that yowls like a cat, but he didn’t lay eyes on the bird making the noise. Things aren’t always what they seem when you’re a bird detective, so the private eye advises Ollie to hang tough, be patient, and see if the bird making the noise might reappear later in the day.

From Egg-laying to Hatching and Beyond May 21, 2024

Waterfowl like this Muscovy duckling spend up to 30 days in the egg, so they’re able to walk, swim, and feed themselves as soon as they hatch. We call these chicks precocial. By contrast, the chicks of most songbirds spend less time maturing in the egg. They must continue to develop in the nest before heading out on their own. We call these hatchlings altricial since they depend on their parents to care for them.

Singing Under Streetlights May 20, 2024

Some birds have always called nocturnally, but other species are relative newcomers to the nighttime music scene, specifically in urban areas. Birds such as American Robins often sing well into the night. Scientists are studying what environmental cues might lead to this behavior. While artificial light could be a factor, recent studies suggest that some birds may be avoiding daytime city noise by singing nocturnally.

Seabirds Drink Salt Water May 19, 2024

Seabirds have no problem drinking sea water. The salt they take in is absorbed and moves through their blood stream into a pair of salt glands above their eyes. The densely salty fluid is excreted from the nostrils and runs down grooves in the bill. As the drop gets larger, the bird shakes its head to send the salt back to the ocean. A seabird's skull has a pair of grooves for the salt glands right over the eyes.

Habitat Defined May 18, 2024

When you think of habitat, think of home. For a jay that lives in the forest, the forest is its habitat – where it finds food, water, shelter, and the company of other jays. Or it might live in your back yard or the bank parking lot down the street. Some birds live in different habitats at different times of year. Many sandpipers summer on the Arctic tundra, but during the rest of the year, they live on coastal tide flats.

The Noisy Willet May 17, 2024

Unlike many shorebirds, Willets breed inland. When nesting is done, they migrate south to both Atlantic and Pacific coastlines in the U.S. and Central and South America. What they all have in common, wherever they have bred and wherever they spend the winters, is an unmistakable voice, combining the insistent petulance of a hungry chipmunk with the lyrical rhythms of a whip-poor-will.

Toddlers – Fledgling Chickadees May 16, 2024

Sometimes in spring or summer, you might see a fledgling songbird. Like a toddler, it’s unsteady, awkward, and learning the ropes. And you might wonder if the young bird has left the nest too soon. (In the case of this Black-capped Chickadee, just 16 days after hatching) But a nest full of begging young can be a target for a predator. So there’s an adaptive advantage for nestlings to exit the nest as soon as they are able, even if they’re not quite ready to fend for themselves.

Preventing Birds from Striking Windows May 15, 2024

When migratory birds fly through populated areas at night, buildings with lights on can cause them to become disoriented. And birds don’t see clear glass windows as an obstacle. Instead, they often see the reflection of trees and shrubs and think they’re flying to safety. Every year, up to a billion birds die when they collide with buildings, including many low-rise buildings and houses. Fortunately, there’s a lot that can be done to prevent birds from striking windows.

Long-eared Owls Fly at Night May 13, 2024

Nocturnal Long-eared Owls tuck up in dense stands of trees across North America and temperate Europe and Asia. They may form communal roosts up to a hundred in number in the winter. After dark, their low-pitched hoots carry for half a mile, as they cruise low over fields, listening intently for their rodent prey. In order to help boost dwindling numbers, wildlife advocates suggest preserving open, fallow fields.

On World Migratory Bird Day, Think of Insects May 11, 2024

Today is World Migratory Bird Day, which recognizes the incredible journeys birds make, the challenges they face, and how we can help them on their way. This year, the focus is on a part of bird migration that is often overlooked: insects. Tiny insects provide food for birds’ big journey north and sustain birds on the breeding grounds. Many insect populations have greatly declined, but people can help by reducing pesticide use, buying organically-grown products, and gardening with native plants beloved by insects and birds alike.

Swallow-tailed Kite May 05, 2024

A bird of prey in the American Southeast takes grace to an utterly new level. It's the Swallow-tailed Kite. A sleek raptor with a deeply forked tail, the Swallow-tailed Kite almost never flaps its wings. The bird makes sudden tight turns, upside-down moves, and quick backward dives, all by pivoting and moving its tail. Kites snatch insects out of the air and take lizards and snakes off leaves with their talons. Then they transfer prey from their talons to their hooked beaks, all while on the wing.

Gulls or 'Seagulls'? May 04, 2024

Gulls seem so much a part of the sea that we often just call them "seagulls," a colloquial title for these graceful, ubiquitous creatures. Twenty-two species breed in North America. The Pacific coast is home to the aptly named Western Gulls. The familiar Ring-billed Gull nests all across the northern states and Canadian provinces. Herring Gulls breed along the Great Lakes and Northeast waterways, while these Laughing Gulls nest all along the Atlantic and Gulf coasts.

Do Parrots Name Their Chicks? May 03, 2024

Parrots are among the smartest of birds. But are they clever enough to know each other by name? Research conducted by ornithologist Karl Berg suggests the answer might be yes. Berg’s studies of Green-rumped Parrotlets — such as the one pictured here — indicate that every parrot in a family flock has a distinct vocal signature learned from its parents. When others in the flock hear it, they know precisely who’s calling.

Spring Birds Arrive in the Eastern Forest May 02, 2024

May in an Eastern hardwood forest, and the chorus of spring birdsong is nearing its peak. The Carolina Wren, a year-round resident, has been singing since the end of winter. The resounding notes of this Ovenbird let us know it has returned safely from Belize, after a long flight across the Gulf of Mexico. A Chestnut-sided Warbler joins in, having returned from winter in Costa Rica, to the same patch of woods in which it nested last year. By late May, the last of the migrants has arrived from the tropics.

Craig Santos Perez and the Last Safe Habitat May 01, 2024

Poet Craig Santos Perez grew up on the island of Guam, and later moved to Hawai‘i where his children were born. Both are places that once flourished with unique and diverse bird life, but because of invasive species and climate change, have seen so much loss and extinction. In this episode, he shares poetry that explores his relationship with lost and endangered wildlife and that reflects on the future his daughter will inherit.

BirdNoir: The Wild Tom Turkey Apr 30, 2024

In this episode of BirdNoir, the private eye gets a call from H. Jon Benjamin about unusual Wild Turkey behavior. A male turkey (known as a “tom”) won’t leave his car alone. He keeps tapping his beak on the car. Then the turkey starts circling the house and looking in all the windows. The private eye reveals how things look from the turkey’s perspective, which points the way to a possible solution.

Birding 101: Finding Birds Any Time of Day Apr 29, 2024

Morning is a great time for birding – that’s the peak of singing and foraging activity for many species. But it’s not the only time to experience birds. Some species, such as American Robins, sing for much of the day. Daytime predators such as hawks and cormorants are active in the middle of the day. Some birds such as Common Nighthawks sweep the sky for insects at dusks. And owls come awake at night.

Beak Meets Seed Apr 28, 2024

Birds like finches, chickadees and Northern Cardinals love sunflower seeds, but each species uses a different strategy to extract the meat. When a finch plucks a sunflower seed from the feeder, it uses its tongue to maneuver the seed lengthwise into a groove on its beak. As it closes its beak, a slight back and forth action slices open the hull, and a small sideways movement husks the seed, while the tongue may help extract the kernel. But chickadees lack the heavy duty, seed-slicing beak of a finch. Instead, they hammer and chip the hull open with the tip of the bill to extract the goods.

Unlikely Places to Go Birding Apr 27, 2024

Birding is often best in the least likely places. At sewage treatment plants, watch for ducks and gulls - and raptors keeping watch over them all. Another place might be your local landfill or dump. The Brownsville, Texas dump was, for years, the only place in the US you could find this Tamaulipas Crow. For a more sedate birding adventure, visit a cemetery. Especially in rural areas and in the Midwest, cemeteries are often repositories of native plants, and thus magnets for migratory birds, which find food – and cover – in those green oases.

Claire Wahmanholm: You Can Always Hear the Highway Apr 26, 2024

Poet Claire Wahmanholm's work focuses on nature and the environment. As she was walking around a nature preserve north of Chicago, Claire was listening for birds but realized there was something else she was hearing: the ever-present hum of a nearby highway. “When you're trying deliberately to hear something else you really notice it,” she says. That experience inspired a poem, “You Can Always Hear the Highway.”

Cactus Wren Nest Orientation Apr 25, 2024

Cactus Wrens, which may nest several times between March and September, carefully orient their nests in tune with the season. These bulky twig structures have a side entrance that curves toward the inner chamber. When building a nest for the hot months, the wren faces the opening to receive the afternoon breeze. By contrast, a Cactus Wren building a nest in early March orients the entrance away from the cold winds of that season, keeping the chicks snug and warm.

Hawai‘i as a Model for Conservation Apr 22, 2024

With invasive species and climate change, Hawai‘i has experienced so much loss and extinction since Western colonists arrived. But Sam ‘Ohu Gon, the Senior Scientist and Cultural Advisor for the Nature Conservancy of Hawai‘i, believes Hawaiian culture and tradition are key to advancing conservation ecology and has done a lot of work connecting these two worlds. He hopes that one day, Hawai‘i can be not just a microcosm of ecology, but of conservation as well.

How Cliff Swallows Build a Nest Apr 21, 2024

When Cliff Swallows arrive on the breeding grounds in North America, the dirty work begins. The swallows scoop up mud in their beaks and carefully build a gourd-shaped nest with a tapered opening. They add a lining of dry grass to keep eggs warm. It takes days of work and a thousand mouthfuls of mud to finish a single nest—and it’s just one part of a large colony.

Creating Bird Habitat at Home Apr 20, 2024

One of the biggest threats to birds is the decline in biodiversity due to habitat loss — and the traditional, manicured lawn isn’t helping. Growing native plants in your yard allows you to protect birds at home, says ecologist Douglas Tallamy, who co-founded an organization called Homegrown National Park® to help people transform their lawns into havens for wildlife.

The Secret to Singing Like a Cardinal Apr 19, 2024

Northern Cardinals have vocal abilities that surpass even the most accomplished human singers. When cardinals sing, they sweep their voices from the high to low end of their ranges many times in just seconds. The secret is in the clever way cardinals use their two-sided vocal organ, called the syrinx. By dividing their vocal range between the two sides, cardinals can sing complex songs rapidly.

Recognizing a Stranded Loon Apr 18, 2024

Loons are built for life in the water – so much so that their legs don’t work well on land. During migration, loons sometimes mistake wet pavement for the reflective surface of deep water and try to land there, then become unable to take flight again. If you see a stranded loon on a road or parking lot, calling a wildlife rehabilitator can help start the process of returning that bird to safety and back on their migratory journey.

Aplomado Falcon Apr 17, 2024

Aplomado Falcons were once widespread residents of the American Southwest, but by the 1950s, they'd disappeared entirely from the region. Loss of habitat, loss of prey, and pesticides all played a role. But in the 1980s, a group called The Peregrine Fund began breeding captive Aplomado Falcons. Over the next 25 years, 1,500 fledglings were set free in South Texas. At the same time, conservation pacts with private landowners provided more than two million acres of habitat.

A hummingbird's brilliant throat feathers are called a "gorget," a term applied in past centuries to the metallic swatch protecting the throat of a knight-in-armor. Light waves reflect and refract off the throat feathers, creating color in the manner of sun glinting off a film of oil on water. The gorget of this Rufous Hummingbird is stunning!

How Birds Survived the Asteroid Apr 14, 2024

The asteroid that struck the Yucatán 66 million years ago wreaked worldwide ecological damage, spelling the end for most dinosaurs and destroying the world’s forests. Yet a few bird-like dinosaur groups made it through. Scientists believe that these groups were all ground-dwellers. Though some species could fly, a life on the ground would have been a key advantage in a world without forests. All modern birds evolved from these ancient creatures.

White-tailed Hawks on the Texas Coastal Plain Apr 13, 2024

The White-tailed Hawk thrives in the grassy plains of the Texas Coastal Plain, where many tropical species reach the northern limit of their ranges. White-tailed Hawks often hunt by kiting: hovering like a kite in the breeze with the wings held in a “V” above the body, dropping suddenly on their prey. When a grass fire breaks out, they hunt small animals fleeing from the fire’s edge.

High Island, Texas Apr 05, 2024

Each spring, millions of songbirds migrate north from the tropics to nest in North America. It takes 15 hours on average to cross the roughly 500 miles of the Gulf of Mexico. If wind or rain slows the crossing, the birds are worn out and famished when they reach land. What will they find on gaining the coast? Along the upper Gulf Coast of Texas, many arriving birds — including Rose-breasted Grosbeaks, like this one — find respite on High Island, Texas.

Flying with Birds and Bats Mar 31, 2024

Bats and birds have evolved very different ways of flying. Birds have stiff feathers projecting from lightweight, fused arm and hand bones; bats have flexible wings of membranes stretched between elongated fingers. While birds use the strong downstroke of their wings to fly, bats support their weight on the upstroke, too, by twisting their wings backward. Bats tend to be more agile in flight, while many birds can fly with greater speed.

Songs and Calls – They're Not the Same Mar 23, 2024

To our ear, the haunting song of this Hermit Thrush is musical, even ethereal. To another Hermit Thrush, the song signals that a male is laying claim to a territory and seeking a mate. These thrushes, like other songbirds, broadcast a variety of calls. Call notes can signal many things – alarm at a predator or aggression toward a rival. Or they may simply maintain contact between members of a pair or flock. So the next time you hear a bird sing or call, listen carefully. You may be introduced to a whole new vocabulary.

Keeping Wood Storks on the Road to Recovery Mar 22, 2024

With their bare heads, long legs and massive bills, Wood Storks seem to have flown out of a fairytale — but in the American South they’re a real-life part of the ecosystem. Developers drained large areas of wetlands, causing the Florida Everglades population to decline to just 5,000 breeding pairs in the 1970s, placing them on the endangered species list. Habitat protection and restoration efforts have helped Wood Storks begin recovering, although they still struggle to find suitable breeding habitat in south Florida.

Flying Dinosaurs: Leaping and Gliding Mar 18, 2024

For years, scientists debated whether the first flying dinosaurs, the ancestors of modern birds, began by running and making little hops off the ground, or leapt off a tree branch to glide. It’s called the “ground up vs. trees down” debate, for short. But a newer perspective on this mystery suggests that flying dinosaurs tried taking flight from more than one place. Recent findings suggest that the ability to fly could have evolved not just once but three separate times among dinosaurs.

In Jamaica, they're known as "Jesus birds," because they appear to be walking on water — a feat made possible by their long toes. But that's not the only cool thing about jacanas. The males, including the Comb-crested Jacana pictured here, can carry their young under their wings. Picture this colorful wading bird, crouching down and spreading his wings. The young scoot in under him, and he sweeps them up and carries them off, tiny legs dangling from under his wings.

Reddish Egret - Lagoon Dancer Mar 13, 2024

The Reddish Egret, a particularly glamorous heron, is best known for its startling antics in capturing fish. When fishing, the egret sprints across the lagoon, weaving left and right, simultaneously flicking its broad wings in and out, while stabbing into the water with its bill. Fish startled at the egret’s crazed movements become targets of that pink dagger. At times, the bird will raise its wings forward over its head, creating a shadow on the water. It then freezes in this position for minutes. Fish swim in, attracted by a patch of shade and . . . well, you know the rest.

Birding 101: Learning How to Strike Out Mar 12, 2024

When you go birding, sometimes you’re in the right place at the right time and there are more species than you can count. Other times, not so lucky. Striking out when looking for birds is frustrating. But a bad day of birding can teach you a lot. Try doing some research into the conditions that day and talking to people that know about birds in your area – they’ll probably commiserate with their own stories about striking out.

Rainwater Basin Mar 11, 2024

For 20,000 years, spring rains and melting snow have filled the playas of the Rainwater Basin of south-central Nebraska. As winter ends, 10 million waterfowl rest and feed there before continuing north. The seasonal wetlands form a funnel for birds heading from the Gulf Coast and points south to northern breeding grounds. In recent years, the number of Snow Geese stopping there in spring has risen dramatically to more than three million birds. A third of North America's Northern Pintails rely on the food-rich habitat there. Twenty-seven species of shorebirds use the wetlands, as well as half a million Sandhill Cranes.

Sandgrouse: Desert Water-carriers Mar 10, 2024

Sandgrouse live in some of the most parched environments on earth. To satisfy the thirst of their chicks, male sandgrouse carry water back to the nest in a surprising but effective way: by carrying it in their feathers. Thanks to coiled hairlike extensions on the feathers of the underparts, a sandgrouse such as this Burchell's Sandgrouse can soak up and transport about two tablespoons of liquid. The sandgrouse chicks use their bills like tiny squeegees, “milking” their father’s belly feathers for the water they need.

The Nasally Fish Crow Mar 09, 2024

The harsh caws of American Crows are one of the most familiar bird calls in North America. Fish Crows sometimes join flocks of American Crows as they forage for food. The two crow species look similar, but have a distinct call that sounds a bit like an American Crow with a stuffy nose. The Fish Crow is found in much of the eastern U.S. and is spreading to new areas north and west to breed.

Introducing Aviary, the Shapeshifting Bird Superhero Mar 08, 2024

In this episode, we meet Aviary: the superhero alter-ego of a mild-mannered birder bitten by a radioactive feather mite. Aviary became able to shapeshift into any of the birds they've seen in their travels — taking on the ultra-fast flight of a falcon or the super-swimming skills of a penguin. Aviary soon realized they’d have to use their powers for good when something seemed off with the local owls one night.

Tree Swallows Spend the Winter Mar 07, 2024

Most swallow species that nest in North America eat almost nothing except flying insects. When the bugs die off in the fall, the swallows head south to winter in the tropical zones of Central and South America and the Caribbean. However, Tree Swallows can also eat small fruits. If Tree Swallows arrive in the north before the insects are out, they’ll supplement their diets with fruit, giving them a competitive advantage for limited nesting sites.

Great Horned Owls Nest II Mar 05, 2024

When Great Horned Owl eggs hatch, the downy owlets are the size of newborn chickens. Their mother broods them day and night. A few weeks later, the owlets can be left alone while both adults resume hunting at twilight. Great Horned Owl young remain in the nest for about six weeks, then climb out onto nearby branches. They begin taking short flights at seven weeks, and can fly well at 9-10 weeks.

Giving Chimney Swifts a Place to Live Mar 04, 2024

Before chimneys existed, Chimney Swifts relied on old hollow trees for nesting and roosting. They can’t perch, they can only cling to a rough vertical surface. As developers cleared old growth forests, Chimney Swifts began using human-built structures. But building styles have changed, making traditional brick chimneys rarer. Pesticides have reduced the populations of swifts’ insect prey. People can help swifts by leaving brick or stone chimneys open from April to October and avoiding pesticides.

Turkey Vultures on the Move Mar 02, 2024

Before we see or feel spring, we often hear it first — in the testimony of a Red-winged Blackbird, the energy of a Song Sparrow, or the serenade of an American Robin. But across much of North America, an earlier sign of spring is the return of Turkey Vultures. In the U.S., you may see them as early as February or March. Unlike most of our returning birds, which migrate at night, Turkey Vultures migrate like hawks — in the daytime. They rise on warm spring updrafts, with a distinctive teeter from side to side. And then they glide — northbound.

How Noise Pollution Affects Birds Feb 28, 2024

Dr. Clinton Francis is a sensory ecologist who studies how noise pollution affects birds, like this Black-headed Grosbeak. He says sounds from machines and vehicles can really disrupt bird behavior. Although birds rely on hearing to sense predators and prey, and to find mates, their sense of hearing isn’t very good, making them very sensitive to noise pollution from machines and vehicles. Fortunately, there are many ways to help birds by reducing noise pollution.

Birds, Berries and Germination Feb 26, 2024

Some plants have evolved fruits with edible flesh that attract birds. When birds swallow the fruit, they also ingest the seeds. They transport the seeds to new spots for the plants to take root. Birds’ digestive systems grind away the hard outer coating of the seed, making it more likely to germinate. Seeds in a bird’s droppings are pre-packaged in nutrient-rich fertilizer.

Hovering Is Hard Work Feb 25, 2024

Hummingbirds are built for hovering flight, with flexible wrists that rotate their wings in a rapid figure-eight motion that generates almost constant lift. Eurasian Skylarks, on the other hand, hovers by fluttering its wings 10-12 times per second, singing all the while. Some raptors such as American Kestrels use a different strategy: by flying into the wind, they can float in place while they scan for prey.

Biomimicry - Japanese Trains Mimic Kingfisher Feb 24, 2024

In the 1990s, train engineers in Japan built trains able to travel nearly 170 miles per hour. The problem was that when the trains exited a tunnel, the air in front of their bullet-shaped noses expanded rapidly, creating a loud “tunnel boom.” The chief engineer, a birder, looked to the shape of a kingfisher’s bill to design long, narrow train noses that parted the air. The trains became both quieter and more efficient.

Dining with Sanderlings Feb 23, 2024

While many shorebirds have gone south, tiny sandpipers called Sanderlings are easy to find on winter shores. They follow the waves as they lap in and out, probing the swirling sand for prey. They often eat various small crustaceans such as mole crabs, isopods, and amphipods. But they also enjoy miniature clams, polychaete worms, and horseshoe crab eggs. They’ll even catch flying insects or eat plant matter.

Lesser Yellowlegs, Loud and Proud Feb 20, 2024

When the shorebirds called Lesser Yellowlegs sense a threat to their nest, they’ll put up an unforgettable racket to drive the danger away. Smaller and with a shorter bill than the Greater Yellowlegs, Lesser Yellowlegs sing to attract mates, while flying or perching up in a tree like a songbird. Although they’re widespread, Lesser Yellowlegs have lost over half their numbers in the last 50 years. Protecting wetlands, addressing climate change, and using sustainable farming practices can all help make sure that this species stays common, loud and proud throughout the Americas.

Nictitating Membranes - Nature's Goggles Feb 19, 2024

For most birds, keen eyesight is critical for survival. But many birds lead lives that can be very hard on the eyes — like flying at breakneck speed, racing for cover into a dense thicket, or diving under water to capture prey. Imagine how the chips fly as this Pileated Woodpecker chisels a cavity. Fortunately, birds have evolved a structure for protecting their eyes. Beneath the outer eyelids lies an extra eyelid, called the nictitating membrane. It helps keep the eye moist and clean while guarding it from wind, dust, and hazards.

Finding Food When it Snows Feb 18, 2024

Fresh-fallen snow is beautiful, but it poses a challenge to birds. The ground where they found food is now covered by several inches of snow. Birds such as juncos and other sparrows flit under bushes where snow doesn’t cover the ground. Finches and chickadees pick at the seed heads of plants sticking out above the snow, while robins (like this American Robin) seek out dried fruits. Nuthatches and woodpeckers cling to trees as they search for insects within the bark.

Costa Rica Winter Sunrise Feb 17, 2024

On a winter morning in Costa Rica, a colorful choir welcomes the day. A pair of Bay Wrens sings a brisk duet just before sunrise. Perched in the upper canopy of the tropical lowland forest, a group of Keel-billed Toucans calls out. In a nearby tree, Purple-throated Fruitcrows (like this one) add their voices to the chorus. Then a male Montezuma Oropendola belts out an electrifying series of notes — one of the most distinctive voices in the tropics. Finally, a Bright-rumped Attila calls from its perch.

Cockatoos and People Trying to Outwit Each Other Feb 16, 2024

In several neighborhoods of Sydney, Sulphur-crested Cockatoos have learned ways to open trash bins and grab some leftover food. Researchers found that birds in a given suburb seem to learn their trash bin opening technique from nearby birds, leading to subtle differences in how cockatoos raid the garbage throughout the city. This has pitted two highly intelligent species against each other as people have tried to come up with deterrence methods to keep birds away from the trash.

Birds have many ways of showing affection for their partners. One way is allopreening, where a bird uses its bill to groom a mate, twirling each individual feather in its beak (like these Macaws). Other birds present their partners with gifts like moss or sticks. A female Arabian Babbler might reciprocate with a gift of her own — or just cut to the chase and lead her suitor to a rendezvous spot in the shrubbery.

Do you ever see flocks of birds in your yard that show up in droves one year, but are completely absent the next? Some nomadic species such as Pine Siskins move based on the availability of food and habitat. It’s called “irruptive” migration, and it sometimes leads to backyards full of siskins. While these flocks are a delight for bird watchers, the dense groups can easily transmit diseases such as salmonellosis.

Roads can get people where they need to go. But they often run right through wildlife habitat, creating a deadly hazard for animals on the move. Liz Hilllard, who’s the Senior Wildlife Biologist for Wildlands Network, says roadkill takes a huge toll on birds and other animals every year. Wildlands Network helps transportation agencies create wildlife-friendly designs and build animal-centric bridges and tunnels for their safe crossing. The goal is to create a connected landscape that Liz and her colleagues call a wildway.

Bird Tracks in the Snow Feb 05, 2024

Look for the stories birds tell with their tracks in the snow. A crow swaggers, leaving right-and-left steps much as a walking human would. Juncos under a birdfeeder leave a hopping pattern of tiny footprints in side-by-side pairs. Look for beak marks, where a bird picked up a choice morsel or probed the ground. Tell-tale signs sometimes tell stories of life and death. You might see mouse tracks end suddenly, just where you find the imprint of an owl's wings. Find out more about animal tracking at the Wilderness Awareness School. And learn more in Bird Tracks and Sign: A Guide to North American Species, a book by Mark Elbroch.

The Wandering Tattler is one of the few birds equally at home along the coast and high in the mountains. They’re found far and wide along Pacific shores, living up to their “wandering” name and gaining names in many local languages throughout the ocean basin. Their nesting habitats in the mountains of Alaska, western Canada and eastern Russia were a mystery for many years. Despite their wide range, there could be as few as 18,000 Wandering Tattlers left in the world.

In 2018, paleontologist Daniel Field took a closer look at specimens from an amateur fossil collector. His team used micro-CT scanning, kind of like a high-energy CAT scan, to visualize the encased fossils. They were amazed to find a tiny bird skull: the earliest known fossil record of a modern bird. The skull looks chicken-like in the front and duck-like in the back. The bird may have looked and behaved like a modern shorebird.

Birding 101: Bird Vocab Basics Jan 29, 2024

Any hobby or special interest has its own jargon. You’ll pick up on the silly slang that birders use as you go – like calling the Yellow-rumped Warbler “butterbutt.” Still, learning a few basics of bird vocab is useful when you’re starting out. It’ll help you ask better questions when you’re confused. Check out the opening pages of a bird field for general info about what to call the different parts of a bird, basics on bird behavior, and birding tips.

The Ferocious Feet of the Great Horned Owl Jan 28, 2024

Great Horned Owls excel at nocturnal hunting, thanks to their acute senses and stealth — but their feet let them secure squirming prey. The outermost of their four toes can rotate forward or backward, an advantage that most other birds of prey lack, letting them capture animals as large as raccoons. A four-pound owl can take flight with six pounds of prey.

Razorbills Swim in Synchrony Jan 27, 2024

Razorbills, a cousin to the puffin, nest in colonies on cliffs. Before they lay eggs, Razorbills take part in two unique social behaviors. In one, the Razorbills swim round and round in a tight mass, then dive as one. Next, they surface with heads aligned and bills held open. In another behavior, dozens of birds swim in a line, then zig-zag in a synchronized pattern across the ocean’s surface.

The Red-bellied Woodpecker and Its Curious Name Jan 26, 2024

Red-bellied Woodpeckers are bold, conspicuous, and vocal, thriving in rural and urban areas east of the Mississippi. Like most woodpeckers, Red-bellieds eat lots of insects. But they also like nuts, berries, and seeds. They can be attracted to back yards with suet cakes, berry bushes, or even a cut orange tacked to a tree trunk. But the Red-bellied Woodpecker retains one element of mystery: its name. The last thing you would likely notice is the blush of rose on its lower belly.

Songbirds: The Large and Small of It Jan 25, 2024

The group of birds called “songbirds” — the perching birds — is incredibly broad. Half the world’s 10,000 birds are in the songbird group, and their range of body sizes is mind-boggling. One of the smallest songbirds in North America is the Golden-crowned Kinglet, barely larger than a hummingbird. The largest is the Common Raven, which is almost two feet long and weighs around three pounds.

Blackbirds' Strange Music Jan 24, 2024

Blackbird songs have a strange music. The Red-winged Blackbird can be heard in nearly every marsh on the continent — bold, brassy, and piercing. The songs may not seem musical, but they definitely get your attention. Brewer’s Blackbirds, which live in open habitats like farms and grasslands, make a wet, slap-in-the-face sound. The combined voices of Tricolored Blackbirds — like this one in a California marsh — sound like a snarling catfight. Another Western bird, the Yellow-headed Blackbird, makes raucous growls, wails, and whistles.

Ducks That Whistle Jan 23, 2024

Whistling as they fly, Black-bellied Whistling-Ducks are gorgeous waterfowl with bright pink bills and legs, chestnut necks and backs, and black underparts. Though most whistling-ducks live in the tropics, Black-bellied Whistling-Ducks are found in the U.S. along the western Gulf Coast and Florida. But they’re expanding their range and have been spotted nesting as far north as Wisconsin.

Bohemian Waxwings – Exquisite Winter Visitors Jan 22, 2024

It's winter, and apples litter the ground. A few still hang, frozen and thawed again and again. Suddenly a flock of hundreds of birds rises from the ground beneath the trees, swarming in tight formation, wing-tip to wing-tip. Bohemian Waxwings are erratic winter visitors from their nesting grounds in the boreal forests of the north. They come in search of fruit to sustain their winter wanderings.

The Tui of New Zealand Jan 21, 2024

The Tui is one of New Zealand’s most remarkable birds, intelligent and with iridescent feathers. Its down-curved beak fits perfectly into native flowers. But the Tui is best known for its voice. Each Tui’s complex song is slightly different, a colorful mix of musical notes and offbeat sounds. It’s one of the few birds that can imitate human speech — and even accents.

Why Is My Robin Half White? Jan 20, 2024

A bird with abnormal white feathers, like this American Robin, may have a genetic condition called leucism. Leucism prevents pigments from reaching some — or sometimes all — of a bird’s feathers. Albino birds are distinctly different and are entirely white with pink skin and eyes. Albinos have trouble making melanin, the pigment in skin, feathers, and eyes.

Welcoming Back Common Loons Jan 19, 2024

The call of the Common Loon is a symbol of the far north. But the species once nested as far south as southern New England, Ohio, Iowa, and California. Human activity and changes to the landscape in these more populated areas has made it harder for loons to persist. There have been encouraging signs in recent years that Common Loons could make a comeback in the southern parts of their range — with our help.

Groove-billed Anis, Communal Nesters Jan 18, 2024

Groove-billed Anis gather in loose groups. And with good reason. They nest communally. As many as four or five pairs of birds may use one nest, a bulky cup of twigs lined with fresh leaves. When the dominant female ani begins to lay her own eggs, the other females lay simultaneously. Up to 20 chalky white eggs have been found in one nest. All parents share the duties of incubating and raising the young. World Birding Centers and the Rio Grande Joint Venture are striving to protect and restore their habitat.

Protecting Rivers and Eagles from Invasive Plants Jan 17, 2024

In the 1990s, eagles in the Southeastern U.S. began dying of a mysterious brain disease. Many years of research identified the culprit: a cyanobacteria that grows on an invasive aquatic plant called Hydrilla — also known as waterthyme. Fish ingested the cyanobacteria, and eagles ate the affected fish. Biologists are now working to contain Hydrilla to prevent more harm to ecosystems. Learn more about invasive plants and their effect on birds, waterways and more on this special season of the Bring Birds Back podcast.

The Heart of a Bird Jan 16, 2024

Birds’ four-chambered hearts run larger than those of mammals, relative to body size, and they are coupled with extremely efficient cardiovascular systems. The energy demands of flight require these adaptations. An exercising human has a heart rate around 150 beats per minute. In contrast, an active hummingbird’s heart pumps at 1,200 beats per minute; a flying pigeon’s heart beats at 600.

A Tool-Using Nuthatch Jan 13, 2024

The nuthatch’s beak is all business. Long, slender, sharp: it can pluck a tiny spider from a crevice in the bark or carve a nest hole right through the outer hide of a tree. And the Brown-headed Nuthatch is even known to use tools! Picking up a flake of pine bark in its beak, the bird uses it as a lever to pry up the bark scales on a tree and get to the insects below. A resourceful bird, the nuthatch.

Find a Volunteer Opportunity that Works for You Jan 12, 2024

Consider finding a local conservation group that’s doing work that matters to you — beach cleanups, volunteer bird surveys, keeping local parks beautiful, or educating young people. If you’re short on time, donations, sharing posts on social media, and letting friends and family know about the good work a conservation group is doing all help advance their mission. And many crowd-sourced science projects depend on people working online and identifying species in photos.

Keeping Cats Indoors Jan 11, 2024

Outdoor cats are one of the biggest threats to birds, killing over a billion a year in North America. And indoor-outdoor cats live much shorter lives than indoor-only cats. So keeping a cat indoors helps protect birds. And there are plenty of ways to make the “great indoors” more exciting for your cat. In this episode, BirdNote producer Mark Bramhill shares his experience with his cat, Pigeon, who enjoys a ‘catio’ — cat-patio — and walks on a leash.

Common Murre, Underwater Flyer Jan 07, 2024

The Common Murre is among the few species of birds that can "fly" under water. When above the water, the 18"-long murre must flap frantically to stay aloft. But beneath the waves, with its flipper-like wings partly extended, it is a streamlined, masterful swimmer. Common Murres, black and white torpedoes with feathers, chase down fish even several hundred feet below the surface. Cornell's Macaulay Library offers audio and video of Common Murres.

Kinglets in Winter Jan 06, 2024

The Golden-crowned Kinglet weighs six grams, about the same as two pennies, yet winters as far north as Alaska and Nova Scotia. The birds move through the forest in small flocks and feed constantly, taking in enough tiny caterpillars to maintain their internal furnace at 110°F. And their insulation keeps them warm. Their feathers make up 8% of their body weight, equivalent to the weight of the clothing of an arctic explorer.

Frigatebirds' Kleptoparasitism Jan 05, 2024

In the warmer regions of the world’s oceans, large seabirds called boobies plunge headfirst into the water, snatching up fish. But as a booby flies up from the waves with a fish now in its gullet, there may be another big seabird — a frigatebird — with its eye on the booby’s fresh catch. Now begins one of nature’s great chase scenes. Fortunately for boobies, frigatebirds don’t steal all their meals. Most of the time, they hunt their own seafood — perhaps a squid snapped from the ocean surface or a flying fish as it skims across the waves.

Why Birds Eat Snow Dec 25, 2023

In the depths of winter, when open water is frozen over, it can be challenging for birds to stay hydrated. Some birds eat the frozen water all around them. Cedar Waxwings catch snowflakes in mid-air. Black-capped Chickadees drink from dripping icicles. Plenty of other birds scoop up fresh, powdery snow and eat it. It could be worth the calories to melt the snow when searching for liquid water could expose them to predators.

How Feathers Insulate Dec 23, 2023

A single Canada Goose has between 20 and 25 thousand feathers. Some are designed to help the bird fly or shed water. Many are the short, fluffy kind, the down that insulates the bird from the cold. Birds survive in sub-zero weather by fluffing their feathers, creating layers of air and feathers. Just a fraction of an inch of this insulation can keep a bird's body temperature at 104 degrees, even in freezing weather. Seen here are the feathers of a Brown Pelican.

For folks looking to try birding for the first time, getting started can be daunting. Should you learn every species’ call, every subtle feather pattern before you head out to look for birds? While it’s good to prepare, there’s a risk of scaring yourself out of starting, and preventing the kind of hands-on experiential learning that’s one of the best parts of birding. So when you have the time and energy, just go for it! Learning about birds is the work of a lifetime — that’s why it’s so rewarding.

The hoots of the Greater White-fronted Goose inspired a nickname, the “Laughing Goose.” A little smaller than Canada Geese, these gray-brown birds are named for the band of white around the base of their pinkish-orange bills. Greater White-fronted Geese are strong, athletic fliers. When family groups come in to land at a roost, they employ a slip-sliding or “falling leaf” maneuver to quickly lose altitude—from over a thousand feet above the ground.

Long-eared Owl - You Don’t See Me! Dec 19, 2023

Long-eared Owls aren’t rare, and they don’t live in remote locations. But their plumage and habits make them incredibly elusive. The mixture of warm browns and cool, bark-like grays lends the bird an astonishingly branch-like appearance. When potential predators approach, the birds close their orange eyes and stretch their bodies so that even the most practiced human eye has a hard time spotting them.

Museum Eggs Help Solve Mysteries Dec 17, 2023

There are five million bird eggs stowed away in museums across the world — and the study of eggs, called oology, can give us great insight into birds. The link between DDT and the decline of Peregrine Falcon populations was identified in part using museum and personal egg collections, and this evidence helped lead to a ban on DDT. And today, Peregrines can still be seen zipping across the sky.

How Much Do Birds Eat? Dec 16, 2023

There used to be a saying about somebody who doesn’t eat much — “she eats like a bird.” But how much does a bird typically eat? As a rule of thumb, the smaller the bird, the more food it needs relative to its weight. A Cooper’s Hawk, a medium-sized bird, eats around 12% of its weight per day. For a human weighing 150 pounds, that’s 18 pounds of chow, or roughly six extra-large pizzas. And that perky little chickadee at your feeder eats the equivalent of 35% of its weight. You, as a 150-pound chickadee, will be munching 600 granola bars a day. And a hummingbird drinks about 100% of its body weight per day. That means you’ll be sipping 17½ gallons of milk.

In Winter, Puffins Lead Very Different Lives Dec 15, 2023

Every summer, puffins — like this Horned Puffin — grow blazingly colorful layers over the bases of their huge beaks. But in the winter, puffins lead very different lives, and they shed their bright ornamentation. Puffins in winter are largely solitary — and silent. They spend about seven months alone at sea, before returning once again to their colonies to breed.

Dwain Vaughns, II, worked as a pilot for 11 years until he developed a rare chronic pain condition called complex regional pain syndrome after an accident. As part of a recreational therapy program, Dwain signed up for a birding trip, but that day he found himself struggling with a racing heart rate. But by stopping and listening to the birds, he found that his heart rate and pain decreased. In the details of bird flight, Dwain sees echoes of his time spent flying planes.

Winter - Nature’s Cold Storage Dec 13, 2023

For birds and other animals with good natural insulation, winter provides a striking benefit as they scavenge. Bacteria function very slowly or not at all in the cold, preventing dead bodies from rotting. In northern latitudes, ravens and other scavenging birds take advantage of winter's cold storage. When a caribou, moose, or deer dies in Canada, Alaska, or other cold place in the winter, it's available to be eaten for months. Bacteria must wait until spring warms the carcass before they can begin to consume it.

The Sword-billed Hummingbird Dec 12, 2023

To out-sip their competition, Sword-billed Hummingbirds have a distinct adaptation: these birds’ beaks are longer than their bodies. Found in temperate forests from Venezuela to Bolivia, these hummingbirds rely entirely on tube-like flowers that other species could never reach. While most birds can use their tongues to clean their feathers, the Sword-billed Hummingbird’s long beak gets in the way – so they use their legs to scratch themselves instead.

Feathered Females in Charge Dec 11, 2023

Male birds are often the larger, flashier sex that courts choosy females, who in turn raise their chicks. But not always. Female phalaropes -- like this Wilson's Phalarope -- challenge each other over territories in which to house a cluster of males half their size. And the males do all the childcare. Other stay-at-home dads include most of the ratites, like ostriches and emus, as well as several species of jacanas.

Great Black-backed Gull, North Atlantic Predator Dec 10, 2023

Great Black-backed Gulls have a reputation as serious predators of other birds. During the nesting season, they’ll prey on eggs and nestlings of other seabirds. They’ll also hunt adult seabirds including puffins and grebes, as well as songbirds as big as a grackle.

Sanderlings Dec 09, 2023

Here and there along winter shorelines, little flocks of pale, silvery shorebirds probe at the water's edge, keeping pace with each wave's ebb and flow. These are Sanderlings, small sandpipers that stay through the winter. Rachel Carson, in Under the Sea Wind, described Sanderlings as running "with a twinkle of black feet." Learn more about the Sanderling at Audubon's online Guide to North American Birds.

How Birds Fly Dec 08, 2023

The secret to birds’ flight starts with the shape of their wings. They’re curved in a way that causes air to flow more slowly under the wing than above it. That creates an area of low pressure just above the wing that pulls the bird up into the sky—a force called lift. Airplane wings are curved in a similar way — but unlike airplanes, bird wings don’t stay in place, they flap! That lets birds push their way into the air from a dead stop. On the upstroke of a wing-flap, birds fold their wings inward, reducing drag on the wing.

Seabirds, Trees and Coral Dec 07, 2023

Palmyra Atoll is a ring-shaped island encircling a lagoon in the South Pacific. The atoll lost many native trees due to U.S. military activity during World War II. Conservationists have worked to restore the ecosystem. Seabirds such as Black Noddies and Red-footed Boobies nest in the island’s rainforest. Their guano enriches the soil, and the soil’s nutrients help support the coral ecosystem that provides fish for the birds.

Great Horned Owl Duet Dec 05, 2023

The 22-inch Great Horned Owl has two tufts of feathers that stick up from the top of its head. This owl is difficult to see, but it's often heard during dark winter evenings and pre-dawn mornings. A pair of owls may call back and forth or overlap their hoots. The male’s call is slightly lower in pitch. Listen for the owl’s night-time refrain, "Who’s awake? Me, too."

Kererū: Pigeons That Get Tipsy Dec 04, 2023

Kererū, green-blue pigeons native to New Zealand, like to sun themselves after dining on fruit. But in warm summer months, the bird’s sunbathing has a surprising side-effect. A part of their digestive system called the crop stores their latest snack – where it begins to ferment, eventually making the pigeons drunk! The rotund creatures often get so tipsy that they fall out of trees, prompting compassionate people to deliver them to local bird rescues and let them sober up.

Listening to Nuthatches Dec 03, 2023

Nuthatches rank high on the list of favorite backyard birds. Compact and stub-tailed, they climb down tree trunks and along the underside of branches with comical ease. One at a time, they flit in for suet and sunflower seeds. But out in the woods, where they spend most of their time, nuthatches are hard to spot. Fortunately, they give themselves away with their voices. Compare the calls of Red-breasted and White-breasted Nuthatches, then head to the woods.

Why Penguin Feathers Don't Freeze Dec 02, 2023

Gentoo Penguins live in the frigid waters of the Atlantic. Only recently have scientists begun to unravel why penguin feathers don’t freeze. An electron microscope revealed tiny pores on the feathers that trap air, making the surface water repellent. This feature, plus a special coating oil from the preen gland, prevents water build-up and delays freezing. Engineers could attempt to apply these principles to prevent icing on plane wings.

Ontario’s Birdhouse City Dec 01, 2023

Driving down a country road in eastern Ontario, there’s a surprising sight by the roadside: dozens of vibrantly coloured, eclectic birdhouses sitting atop 12-foot poles. It’s called Birdhouse City, and it’s in a conservation area boasting close to 100 birdhouses, with 30 under renovation. The initial birdhouse designs were based on nearby historical buildings, from the general store to the courthouse. About a third of them are occupied, with several species reliably taking up residence.

Building Nature Trails Accessible to Blind People Nov 30, 2023

When Juan Pablo Culasso spends time outside, he often encounters people thinking he doesn’t belong out there as a blind person – despite the fact that he’s a renowned nature recordist. He helped design nature trails in Colombia with features that make them more accessible for people who are visually impaired, including guide ropes with textures that signal points of interest and QR codes that provide info. But Juan Pablo says these are not simply trails solely for blind people to enjoy — “we need to share the same places in society,” he says.

Swans Come Calling Nov 29, 2023

Trumpeter Swans land in a plowed field to forage for remnant potatoes, grain, and other waste crops. This swan is among the largest of all waterfowl; the Tundra Swan is somewhat smaller. These swans migrate in family groups each fall from nesting sites in Canada and Alaska. Learn more about these swans, and view a map to the Skagit Flats of Washington where you can see them. When you go, please be courteous, and if you stop, pull completely off the roadway. Always respect private property.

Giant Owls of Cuba Nov 28, 2023

The Cuban Giant Owl, now extinct, was 3½ feet tall and weighed 20 pounds — the largest of all known owls. It had very small wings, running after its prey on long, powerful legs. Similar large owls, with long legs and small wings, have been unearthed in places as disparate as Georgia and Hawaii. Very little is known about why giant owls died out.

A Pigeon-eyed View of the World Nov 26, 2023

Pigeons — and other birds with eyes on the sides of their heads — have a different view of the world from that of creatures with forward-facing eyes. The images from a pigeon’s eyes overlap slightly, so the bird can see in front of itself, even though it has worse depth perception. But these laterally placed eyes have a big advantage for prey species: they provide a much wider view of the world. A pigeon has a remarkable 340º view without moving its head, including a wide area behind its head!

Common Redpoll Nov 25, 2023

The tiny Common Redpoll, one of the smallest members of the finch family, weighs only as much as four pennies, yet it survives the cold and darkness of winter in the far North. Most birds depart in autumn to warmer climes. But redpolls feed on birch and alder seeds that are available throughout the winter, no matter how deep the snow. This little bird typically eats 40% of its body weight in seeds every day to keep itself alive. Redpolls are survivors.

Female Birds Sing in the Tropics Nov 24, 2023

In temperate climates like North America, it’s often male songbirds that sing the most. Typically the males migrate north before females and establish territories for the short breeding season, using their songs as a way to claim a spot. But many female birds do sing, even in colder climates. And in warm tropic zones, female birds often have a big role in defending a territory, and many of them sing just as loudly and artfully as the males.

Birds like male turkeys or barnyard roosters have a wrinkly, bumpy flap of red skin called a wattle. But what are wattles for? Birds can’t sweat, so wattles help release excess heat. Wattles are also key to courtship displays. Many other birds, including some storks and plovers, also have wattles.

The Jay Game Nov 22, 2023

Many jays, including this California Scrub-Jay, store food for sustenance in harsher seasons. An individual bird may cache nuts, insects, and even worms in several thousand spots. If jays visit your yard, here’s a game you can play with them. Each day, preferably when the jays aren’t watching, place a dozen peanuts in different parts of the yard. They should be visible, but scattered. When a jay arrives, watch how long it takes to find the nuts. The next day, place the nuts in a different array and watch again. Do the jays find them quickly? They might already have a mental map of everything in the yard, so anything new — like a peanut in a novel spot — seems to jump out at them.

Bill Shape Equals Food Source Nov 20, 2023

A fine woodworker has a chest full of tools, each designed for a specific task. Birds also have highly refined tools-their bills. The size and shape of a bird's bill match perfectly the food they seek and the way in which they obtain their meals. Different species of shorebirds that forage shoulder to shoulder in tidal estuaries (like this Marbled Godwit and Willet) have bills of different lengths. As a result they don't compete for the same food.

Fairy-Wrens - To Duel or Duet? Nov 19, 2023

The Red-backed Fairy-Wren, a tiny songbird living the Australian scrublands, is highly territorial and promiscuous. The male can’t be sure the eggs in his nest are his own. One way to help avoid this problem? The male may rough up a rival who approaches his territory. But research shows when Red-backed Fairy-Wren pairs sing a duet in order to deter rival males from intruding on their territory, those pairs had more of their own genetic offspring in their nests. For the male, aggression might not ensure paternity, but singing a duet could.

Loggerhead Shrike Nov 12, 2023

Loggerhead Shrikes are found across much of the United States in open country, like pasture and sagebrush. Male shrikes are well known for impaling their prey on thorns, creating a larder that may help impress potential mates. But pesticides and the loss of habitat to residential and commercial uses have reduced shrike populations. Conservation efforts are under way, such as allowing brush to grow along fence-lines, leaving small trees and shrubs on the roadside, and reducing or eliminating the use of pesticides.

Decibels Per Gram Nov 10, 2023

Some of the tiniest birds in the world have impressively loud voices. The Ruby-crowned Kinglet — that bright-headed sprite of the treetops — would be downright deafening if it were just a little bigger. Hummingbirds were originally named for the mechanical buzzing produced by their inconceivably fast wing-beats. But some males, such as this Costa’s Hummingbird of the Southwest, are equally notable for their vocal attainments. Late in winter, these tiny gems flash their purple throats and utter a startlingly loud, ear-piercing whine.

Common Potoo: Branch or Bird? Nov 09, 2023

Common Potoos are champions of camouflage. In the daytime these nocturnal creatures perch perfectly still on branches: heads pointed upward, bodies outstretched, and eyes closed down to tiny slits. It’s hard to tell where the branch ends and the bird’s body begins — which helps them avoid predators. They’re birds more often heard than seen; with a melodious but mournful song, made at dawn, dusk and by the light of the moon. The song earned potoos the name ‘Poor-me-one’ in Trinidad and Tobago.

What the Pacific Wren Hears Nov 05, 2023

What does the Pacific Wren hear in a song? It's a long story. What we hear as a blur of sound, the bird hears as a precise sequence of sounds, the visual equivalent of seeing a movie as a series of still pictures. That birds can hear the fine structure of song so acutely allows them to convey much information in a short sound. Pacific Wrens are found most often in closed-canopy conifer forests, nesting in cavities, usually within six feet of the ground.

Urban Cooper’s Hawks Nov 04, 2023

Next time you’re in the city, look up. When pigeons are wheeling, you might just see a different bird in pursuit. The Cooper’s Hawk, once known as the “chicken hawk,” used to be in steep decline due to hunting and the effects of DDT on breeding. Today, it’s the most abundant of the bird-eating raptors over much of North America, living even in the city. Males are smaller and often prey on Mourning Doves and other easy pickings at city parks. The bulkier females hunt pigeons, adding a dash of wildness and drama to the modern cityscape — in the form of pigeon feathers falling silently from the sky.

The Music of Birds Migrating in the Night Nov 01, 2023

Ornithologist Bill Evans has helped us better understand the sounds that birds make as they migrate at night. Known as nocturnal flight calls, many species can be identified based on their signature sound. Using special handmade microphones left outside overnight, Evans, his colleagues and many volunteers recorded countless nocturnal flight calls — and not all of them have been identified yet. In this show, revel in the beauty of the calls that birds make as they fly high in the air.

The Vampire Finch Oct 31, 2023

Vampire Ground-Finches menace their victims in broad daylight, stabbing holes in their flesh, then devouring the blood. During the dry season, when their usual diet of seeds can be scarce, they turn to large seabirds, like boobies. Fluttering onto a booby’s back, the finch jabs its sharp beak in among the feathers until blood flows, making a meal of it. Why boobies tolerate this remains a mystery.

There’s More Than One Way to Climb a Tree Oct 30, 2023

No bird is better adapted for climbing up a tree trunk than a woodpecker. The foot of this Pileated Woodpecker is ideal for clinging, and its relatively short legs allow it to anchor itself securely. When traveling upward, the woodpecker’s a master. But hitching down? Not so much — usually they will fly. Nuthatches, however, can easily go up and down. This White-breasted Nuthatch walks over the bark of trees by grasping with one leg while using the other for a prop. It also has a rear-facing toe equipped with a long, sharp claw that’s ideal for hanging on while heading downward.

How a Bird Came to Look Like a Caterpillar Oct 29, 2023

The Cinereous Mourner is a small, ashy-gray bird that lives in the forest understory of the Amazon Basin. And it’s taking mimicry to the next level: when viewed from above, lying alone in its cup-shaped nest, its chick is a near match to a highly toxic caterpillar — one that snakes and monkeys won’t eat. The chick even waves its head like a caterpillar, increasing the illusion.

What Makes an Efficient Flying Bird? Oct 28, 2023

Every bird species uses its wings a little differently, and some are specialized for highly efficient flight. But that means going without other abilities. Swallows and hummingbirds (like this Talamanca Hummingbird) capture their food on the wing, but they can’t walk. Swifts, which are acrobatic in the air, can’t even perch. Yet they dazzle with the maneuverability made possible by their aerodynamic bodies.

Surfing with Scoters Oct 27, 2023

Surf Scoters are perfectly at home in the element they’re named for. They swim smack in the middle of what surfers call the impact zone: Just where the waves break with greatest violence. Why risk the harshest waves when there’s calmer water close by? Because the churning action of crashing waves can expose the small clams and crabs that scoters eat. And how do Surf Scoters avoid getting mashed by the sea? When a towering wave is about to crash down, the scoter deftly dives and swims under the crest of the foaming breaker, then pops up on the other side.

The Sociable Weaver’s Colonial Nest Oct 25, 2023

When it comes to nests, common sense suggests that large birds build large nests, and small birds build small nests. But in fact, some species of smaller birds build large nests. None, though, builds anything like the communal structures of Sociable Weavers in southern Africa’s arid plains. These House Sparrow-sized birds often live in accommodations with room for up to 500 birds. Each family has its own access hole and tunnel into a chamber within the larger complex. Some structures have persisted for more than 100 years, with constant occupation by succeeding generations.

Altitudinal Migration Oct 23, 2023

Yellow-eyed Juncos sometimes make a migration of sorts — not from north to south, but from the high mountains to the lowlands or the other way around. It’s called altitudinal migration. In the warm summer months, some Yellow-eyed Juncos prefer to nest at higher elevations, while in winter, the scarcity of food pushes them back down to the valleys.

What an amazing array of sounds birds have to offer! The call of a male Yellow Rail sounds like someone tapping two small stones together. And Turkey Vultures hissing at one another over a carcass sound like a snarling lion. The duet between the male and female Barred Owls seen here is especially raucous. BirdNote gets most of its sounds from The Macaulay Library of Natural Sounds.

Hummingbirds - To Feed or Not to Feed? Oct 19, 2023

Have you wondered about the right time to remove your hummingbird feeders during fall? Consider leaving your feeders hanging for a week or two after you’ve seen the last hummingbird of the season, just in case a late migrant stops by to fatten up. However, Anna’s Hummingbirds – like the one pictured here – benefit from feeders year-round. This species is largely non-migratory, residing from California to southern British Columbia.

Even if the name Spix's Macaw doesn’t ring a bell, you might recognize this bird. It’s Blu, from Rio, the animated film! Also known as the Little Blue Macaw, the species went extinct in the wild due to hunting for the pet trade, loss of habitat, and invasive species. However, scientists raised a captive population of Spix’s Macaws from the few remaining wild birds. In 2022, 52 of the captive-raised birds were released into the wild.

Preserving John Edmonstone Oct 16, 2023

John Edmonstone was born on a timber plantation in British Guiana, and enslaved by Scotsman Charles Edmonstone. He learned taxidermy techniques by accompanying a naturalist on expeditions. In Scotland, he became a free man and began working as a taxidermist. One of his students was a teenaged Charles Darwin, who would later use the skills he learned from John to preserve and study the Galapagos birds that formed the basis of his theory of evolution.

Sungrebe: Baby on Board Oct 15, 2023

Birds have developed many strategies for protecting their young. But only one species can tuck its chicks into pouches under its wings, then fly the young to safety. It’s the Sungrebe of Central and South America. Despite the name, they are not closely related to grebes. Sungrebes swim and dive on quiet freshwater streams. Both sexes incubate the eggs in a nest on branches just above the water. But when the young hatch, naked and helpless, the male takes them under his wing. He’ll swim — and fly if he needs to — with chicks on board until they’re able to swim.

From Alaska to Omaha, Then on to Brazil Oct 14, 2023

Blackpoll Warblers make one of the longest migrations taken by a songbird in the world. Blackpoll Warblers that breed in Alaska fly southeast in the fall, appearing throughout the Midwest and eastern U.S. on their way to the Atlantic Coast. Then, they make a nonstop flight over the water to reach South America. Scientists uncovered the stranger-than-fiction details of Blackpoll Warbler migration thanks to a tool called a light-level geolocator, which uses day length to figure out where a bird traveled.

Canada Geese - Migratory or Not Oct 12, 2023

It's the time of year that geese migrate south for the winter. Isn't it? So why are there so many geese still hanging around, setting up housekeeping on our parks and golf courses? Did they decide to forgo the long trip north? In the early 1900s, non-migratory geese were brought in by the hundreds to populate wildlife refuges. Now, while many Canada Geese migrate south for the winter, these other geese stay -- and multiply.

The Ballet of the Grebes Oct 11, 2023

When a pair of Western Grebes decides it’s time to mate, they call loudly and approach one another. Each bird curves, then straightens, its long neck gracefully. They then face each other, necks on the water’s surface, their bills flipping up drops of water. If attraction prevails, they rush together and off they go across the water, running on the surface side by side. Standing straight up with necks held high and feet churning like propellers, they no longer look much like grebes - more like participants in Tchaikovsky’s ballet, Swan Lake.

Left Foot or Right? Handedness in Birds Oct 08, 2023

A parrot’s eyes are located on the sides of its head. So, if it wants to look at something — say, a delicious piece of fruit — it has to cock its head one way or the other do it. And if it looks with its left eye, then uses its left foot. Scientists call this handedness. That’s when one hand — or foot — is used consistently over the other for doing complex tasks. Sulphur-crested Cockatoos are almost all left-handed ... that is... left-footed.

Ducks - Diving and Dabbling Oct 05, 2023

Autumn brings many species of wintering ducks and seabirds to our waters. Watch carefully. Some dabble along the surface, feeding along shallow edges of lakes and estuaries. Others dive under the water, using their feet and occasionally their wings for propulsion. The male "dabblers" are often bright and colorful, whereas the females are mottled brown. The "divers" tend to be less colorful.

Janet Ng on Surveying Waterbirds by Kayak Oct 04, 2023

Wildlife biologist Janet Ng works for the Canadian Wildlife Service. And for her waterbird surveys, one of the most important tools of her trade is a kayak. Many species that breed in the Arctic pass through lakes in southern Saskatchewan on their way north, making it a great place to survey the birds’ populations and track how they’re doing year to year. But some birds are hard to see, hidden in cattails. So counting them by kayak gives biologists a chance to observe more birds.

Bumblebee Hummingbird: The Mexican Buzzer Oct 03, 2023

Mexico's Bumblebee Hummingbird is one of the smallest birds in the world. Less than 3 inches in size and weighing less than a bottlecap, they’re easily confused with a bumblebee as they buzz by. But as tiny as they are, they defend their breeding territories fiercely. Perhaps that’s why the ancient Mexicas associated hummingbirds with their most important god: Huitzilopochtli, the god of war…and of love. Huitzil means hummingbird in Náhuatl.

Hooded Merganser Sep 30, 2023

Hooded Mergansers, affectionately known as “Hoodies,” nest across most of the northern US and well into Canada. They’re especially prevalent around the Great Lakes, though some winter as far south as Florida. By November, courtship and pair formation is well under way. And by early spring, Hoodies will seek out secluded woodland ponds, where they nest in tree cavities or manmade nestboxes. Hooded Merganser eggs are nearly spherical, with surprisingly thick shells. They’re ideally suited to the Hooded Merganser’s nest of choice — a cavity or a hole.

Millicent Ficken Studied How Birds Play Sep 25, 2023

Millicent Ficken spent her career studying bird behavior and communication. The first woman to earn a PhD in Ecology and Evolutionary Biology from Cornell in 1960, Ficken authored over 100 scientific papers. She discovered that male hummingbirds have a whole repertoire of songs rather than just one, outlined the linguistic differences between penguin species, and showed that chickadees take turns singing in the morning. She was especially fascinated by how birds play, showing that bird play almost always has a pressing purpose — they're practicing a skill they need to survive.

Brown-headed Nuthatches of Apalachicola National Forest Sep 23, 2023

Many Brown-headed Nuthatches make their home in the tall longleaf pines of the Apalachicola National Forest in Florida. Twittering constantly, the birds probe for tiny insects or extract seeds from cones in the trees’ upper branches. Forests of longleaf pine once dominated the sandy coastal plain from Virginia to Texas, but the tall, straight pines proved irresistible for their lumber. Now, much of the forest is gone, replaced by dense planted stands of quicker-growing slash pines.

As our population grows, and more and more land is devoted to human uses, our national forests become increasingly important for birds, both rare and common.

Resplendent Quetzal: Mexico’s Sacred Bird Sep 19, 2023

Found in Southern Mexico and Central America, Resplendent Quetzals have a striking blue tail up to three times the length of their bodies. That's probably why the Aztecs considered this bird a representation of Quetzalcoatl, the feathered serpent, one of the most worshiped gods across ancient Mesoamerica. But no matter how sacred, Resplendent Quetzals are currently considered near threatened due to a declining population. Deforestation and illegal trade are the main threats to their survival.

Finches Singing Over the Sidewalk Sep 18, 2023

The songs of two common finches provide a steady soundtrack in cities across North America: the House Finch and the American Goldfinch. While they can sound similar, a couple of key features help set them apart. House Finches sing sweetly but often have a sharp, buzzy note near the end. Goldfinches sing rapidly, often repeating a note several times. They also often make their distinctive call, which sounds like someone quickly saying “potato chip!”

Raptors in the Mojave Desert Sep 16, 2023

Desert raptors get most of their water from eating prey animals. Biologist Blair Wolf explains, “if you think of any insect or a mouse or something like that, they’re maybe 75% water.” Those animals become less plentiful in a hotter, drier climate. Extreme warming poses a direct danger to the raptors (such as this Harris's Hawk) and leads to lower rates of reproduction. Lacking sufficient water, they may not be able to produce eggs, and there must be enough food for their nestlings to thrive.

Climate Change Leads Male Birds to Migrate Sooner Sep 15, 2023

For years, biologists have been seeing migratory birds arriving earlier in the spring due to the effects of climate change. But surprisingly, the effect on arrival time is different for members of the same species. Male birds are changing their arrival dates faster than females in many species of birds that breed in North America. While it’s still unclear what effect this has on bird populations, understanding how climate change can affect females and males differently can help guide our conservation efforts.

Amazing Aquatic American Dipper Sep 14, 2023

The American Dipper stands on a rock in a stream, bobbing up and down on its long legs - "dipping" - hence the name. But watch! This nondescript bird steps off a small boulder right into the torrent, and begins to peer under water. What the American Dipper might lack in bright color it more than surpasses with amazing aquatic abilities. You can learn more about river restoration and protection at American Rivers.

Seeing the Rainbow in a Bird’s Feathers Sep 13, 2023

We make it a habit to detail the broad and beautiful spectrum of bird colors, but iridescent feathers are undoubtedly among the most mesmerizing. When sunlight hits the Bufflehead’s dark head feathers at the right angle, their colors transform into shades of the rainbow, from deep violet to green and gold. Common Grackles, caught in natural light, gleam gold, green and blue-purple. Starlings, too. And the dull gray Rock Pigeons shuffling around a city park might reveal a glimpse of the electric teal and lavender, shifting shades on their throat.

Kelp in the Eagles’ Nest Sep 12, 2023

A pair of Bald Eagles will reuse their nest each year and repair it with new tree branches. But recently in British Columbia, scientists came across an eagle nest made largely out of dried kelp. Back in the ‘90s, that very nest had been made out of tree branches. What changed? Sea Otters were reintroduced to the landscape, which helped kelp forests flourish — and occasionally wind up in an eagle’s nest.

Woodpeckers Carve Out Roost Cavities, Too Sep 11, 2023

In spring, we often hear woodpeckers hard at work, carving out nest holes in tree trunks. And now that fall has arrived, we may hear that excavating sound again. Some woodpecker species stay year round in the region where they nest, while others migrate south in winter. Those that remain, like this Pileated Woodpecker, are chiseling out roosting cavities, snug hollows where they’ll shelter during the cold nights of fall and winte

Migration Takes Guts — Until It Doesn’t Sep 10, 2023

This Bar-tailed Godwit makes one of the longest migrations of any animal — a 7,200-mile non-stop flight each autumn from western Alaska to New Zealand. In his book A World on the Wing, Scott Weidensaul explores the remarkable transformation godwits undergo to make this migration possible. Their digestive organs shrink as their weight more than doubles in stored fats and muscle mass.

Cowbird Song and Password Sep 09, 2023

As most young male birds get ready to leave the nest, they learn their species’ song by hearing their male parent sing it again and again. They imprint on their father’s song. So how does a Brown-headed Cowbird, raised by parents of a different species, learn to sing the correct song? The “chatter call” of an adult cowbird triggers something in the young bird’s brain. Like a kind of “password,” the chatter call guides the young bird in recognizing what species to identify with, even though cowbirds are fostered by as many as 220 different species!

Parrots Using Video Chat to Keep in Touch Sep 08, 2023

Knowing how clever parrots are, researchers wanted to see how they’d respond to another parrot saying hi on a tablet or phone. After being trained how to start a call, many parrots chatted amiably on calls and stayed on for the maximum amount of time. Some birds even seemed to develop friendships, choosing to stay in touch even after the experiment ended.

New Zealand Bellbird Sep 07, 2023

A forest in New Zealand rings with the sound of bellbirds, also known as Korimako or Makomako. Many bellbirds sing together, especially in the morning. Pairs sing duets. And a pair may counter-sing with its neighbors, perhaps letting them know that this patch of land is taken. It all builds to a brilliant, ringing dawn chorus.

Juvenile Shorebirds Head South Sep 06, 2023

Like most juvenile shorebirds, this young Black-bellied Plover was abandoned by parents that began their southbound flights from the Arctic National Wildlife Refuge a few weeks earlier. It will join other young Black-bellied Plovers as they make their way south. This little flock of birds could arrive on the coast of Washington within a few days if they make a direct flight, or within a week or more if they stop at a wetland along the way. Some will stay, but others continue their continent-spanning journey, arriving in coastal Venezuela at the end of December.

Migrations: The Triumphant Comeback of the Aleutian Cackling Goose Sep 04, 2023

Aleutian Cackling Geese, which have a slighter build and shorter beak than Canada Geese, build their nests on a chain of islands off the western coast of Alaska. In the 1700s, fur traders introduced foxes to the islands, nearly wiping out the geese. For decades, they were believed to be extinct. But in the 1960s, a biologist discovered about 300 birds nesting on Buldir Island. Habitat protections have allowed their populations to recover.

Swifts Roost in Chimneys Sep 03, 2023

What could bring crowds of people out after sunset on a September evening to stare at ... a chimney? Swifts, of course! Scores of swifts form a funnel-shaped cloud above the right kind of chimney, then they begin their descent. First one, then a few more, then dozens, then hundreds swirl right down into the chimney. You can help Chimney Swifts and Vaux's Swifts by providing a roosting tower.

The Alula Sep 02, 2023

Adjusting the flaps on an airplane’s wing allows a pilot to control lift and drag — and the design of these flaps was inspired by the wings of birds. All flying birds have what’s called an alula on each wing. At the center of the front edge of the wing is a structure covered with three to five feathers that functions much like a flap on an airplane’s wing. The alula helps create lift and also prevents stall when a bird comes in for landing.

Migrations: Indigo Bunting, Master Stargazer Aug 31, 2023

The stars appear to rotate in the sky, raising the question of how birds can use stars to navigate during migration. Ornithologist Stephen Emlen brought Indigo Buntings to a planetarium, tracking their movements as the simulated night sky changed above them. The buntings oriented themselves using star patterns that appear to rotate the least — especially the North Star, Ursa Major and Cassiopeia.

Birds Love Sunflowers Aug 30, 2023

Found throughout North America, the common sunflower can grow up to ten feet high, towering over other herbs and grasses. And that’s only half the story: their roots can reach just as deep in the soil. They’re rugged, adaptable plants that bring beauty — and food — to the ecosystem. Planting sunflowers in a public green space or a backyard can benefit pollinator insects as well as finches and other birds that seek out their seeds, which often last well into the winter.

The Harsh Beauty of Grackle Songs Aug 29, 2023

Ranging from metallic hisses to electronic yodels, sounds of grackles may not be music to our ears—but they have their own rough beauty, a distinctive, primal harshness. Grackle songs evolved to carry through their nesting habitats — dense marshes and brushy landscapes — where more lyrical notes and phrases wouldn’t carry well. However strange they may sound, they know how to make themselves heard.

Moon-Watching for Migrating Birds Aug 28, 2023

Before the high-tech gadgets used to track bird migration today, there was moon-watching: a technique dreamed up in the 1940s by ornithologist George Lowery. Using telescopes pointed at the moon to see the silhouettes of migratory birds, Lowery helped show that birds regularly migrate across the Gulf of Mexico and organized the first continent-wide survey of migration in North America. Learn more about the history of bird migration research in Rebecca Heisman’s new book Flight Paths: How a Passionate and Quirky Group of Pioneering Scientists Solved the Mystery of Bird Migration.

Watching Birds' Behavior Aug 27, 2023

To distinguish one bird from a similar one, watch how the bird moves. Does it flick its wings? Bob up and down? Flip its tail? The White-breasted Nuthatch (right) works its way down the trunk of a tree, while the Brown Creeper works its way up. A field guide usually mentions these behaviors, and watching for them can help you determine which bird is which. It's like detective work: gather enough clues, and you'll solve the mystery!

Where Do Fledglings Go? Aug 26, 2023

By late summer, most birds hatched in spring are on their own, without help from their parents. Where do they go? Young migratory birds will head south in late summer or fall, in the pattern of their species. But most non-migratory birds born last spring — such as this immature Bewick’s Wren — will need to find an unoccupied territory. So they disperse more widely than the established adults. Newly fledged Bald Eagles embark on a nomadic life. Sometimes they fly hundreds of miles in a day, a journey that may take them across the continent.

Arizona Woodpecker and the Sierra Madre Aug 25, 2023

Found in the Sierra Madre, the Arizona Woodpecker has a special connection to the mountain range. Sharing mid-elevation pine and oaks with fellow border straddlers, these small brown birds with white and brown cheeks stand out from other Woodpeckers with their heavily marked white underparts. Uniquely, they forage by flying to the base of a tree and then spiraling up the trunk. And in courtship, the male turns himself into a paper airplane, holding his wings steady and gliding toward his mate.

Do Crows Sing? Aug 24, 2023

It’s been said that if someone knows only three birds, one of them will be the crow. They’re common, easy to see, and even easier to hear. But crow voices are complicated. Altogether, crows may use 30 sound elements in different combinations, and one of the most intriguing is their song. Unlike many birds, crows don’t sing loudly to attract mates from a distance. Instead, they sing softly — and at close range — during courtship, with a mix of soft cooing, rattles, growls, bowing movements, and mutual nuzzling.

Southern Lapwings Defend Their Nest Aug 23, 2023

Nature educator Johanne Ryan shares her observations of Southern Lapwings, shorebirds that make their nests on the ground in open areas and vigorously defend them. If a potential predator approaches, the parent will sound a piercing alarm call. If that doesn’t work, the lapwing will charge the opponent, using a secret weapon – sharp, bony spurs on the bird’s “wrists.”

Why Do Some Birds Flock? Aug 22, 2023

When birds like these Dunlin form flocks, each individual is less likely to be captured by a predator. Some shorebirds that forage with their heads down, like godwits, will flock with birds that forage with their heads up, like curlews. Still other birds work together — like American White Pelicans driving fish before them or auklets that surround schools of herring and herd them like a border collie does sheep.

A Song That Has Survived for Thousands of Years Aug 21, 2023

Sometimes, a species’ song changes over the course of a few decades. But a bird that lives in the mountains of eastern Africa, the Forest Double-collared Sunbird, appears to have kept the same song for at least 500,000 years. That’s the amount of time that two populations of the species split up into two separate mountain ranges. Despite a lack of contact between those populations, they sing a nearly identical song, suggesting that it’s very similar to the one their ancestors sang long ago.

Pigeons and Head-bobbing Aug 20, 2023

Pigeons seem to bob their heads as they move, like they’re grooving to an internal tune. But what look like head bobs are actually momentary pauses of the head while they walk. Their eyes are fixed in their sockets, so that pausing enables the pigeon to take a brief, steady view of its surroundings. Without those pauses, they’d just see a Blair Witch, shaky-cam mess!

Birds Crossing the Pacific Aug 18, 2023

Over 12,000 miles across at its widest point, you might think the Pacific Ocean is a barrier that even high-flying birds can’t cross. Think again – some species make the trip every year as part of their life cycle. During the spring, Bar-tailed Godwits break up their trip from New Zealand to Alaska with a stop in the Yellow Sea off the coast of East Asia. But for their winter migration, they fly from North America to New Zealand without stopping. The longest recorded godwit journey is over 8,000 miles of uninterrupted flight.

In her grandmother’s neighborhood in Chicago, Lilli Holden made an early connection with the outdoors by playing in a vacant lot with a large old tree. Now an emerging environmental leader in Chicago, Lilli has a different perspective on vacant lots, many of which were properties destroyed in the city’s 1968 riots that were never rebuilt due to a lack of investment in Black communities. Because they’re such a big part of the landscape in Black communities on the West and Southside, Lilli wants to rethink how vacant lots fit into the ecology of these economically-challenged neighborhoods.

Male Northern Cardinals, Scarlet Tanagers, and House Finches all have striking red plumage that’s thought to play a role in attracting mates. Males with the brightest red feathering tend to have the best luck with the females. Scientists think that a male’s redness signals to females that he has just what it takes to help produce superior offspring. But just because a male is a brilliant shade of red... does that mean he’s stronger or more fit than his duller-colored competitors? It might be so, but it’s complicated…

Blind Snakes and Screech-Owls Aug 05, 2023

During the breeding season, when Eastern Screech-Owls capture the worm-like reptiles known as blind snakes, they deliver them to their chicks alive and wriggling. Some are gulped down immediately, but others escape by burrowing beneath the nest. The surviving “snakes” feed on the insect larvae they find in the nest — larvae that would otherwise parasitize the owl nestlings. A study conducted by Baylor University scientists found that screech-owl chicks grew faster and healthier in nests kept vermin-free by the blind snakes.

Sleeping on the Wing Jul 30, 2023

Some swifts and frigatebirds stay aloft for months. But for a long time, scientists did not know if the birds might be sleeping on the wing. A 2016 study provided answers. Tiny devices attached to the heads of frigatebirds revealed fascinating information: the birds did sleep while aloft, most often one half of the brain at a time. But they also fell into normal, whole-brain sleep and sometimes, even deeper REM sleep. But this deepest sleep came in bursts of just a few seconds — an inflight power-nap.

Sparrows Sing in Arizona Monsoon Jul 29, 2023

Midday temperatures in southeast Arizona soar above 100 degrees during the month of July. But relief is coming. A summer monsoon refreshes the Sonoran Desert like a second spring. Grass grows lush, wildflowers spring forth, and birds sing. Cassin’s Sparrows sing their plaintive phrases almost nonstop. Botteri’s Sparrows add their distinctive sputters and trills. And a Rufous-winged Sparrow — like the one pictured here — voices its gentle melody.

The sounds heard in this episode were recorded by Gordon Hempton and provided courtesy of QuietPlanet.com.

Stowaway Birds Jul 28, 2023

When they migrate, tiny songbirds that spend most of their lives on land fly hundreds of miles over the ocean at a stretch – and they get tired. A recent study suggests that birds migrating over busy shipping routes in the Mediterranean Sea may use the decks of sea vessels as places to catch their breath when the weather turns bad.

Paradise-Whydah Jul 27, 2023

A few times each year, the Eastern Paradise-Whydah puts on its party clothes. This small finch is found in East Africa, and males and females generally share the same nondescript appearance. But when it’s time to mate, the male sprouts extravagant, long, black tail feathers two or three times the length of his body. The feathers make it look like he’s wearing a long black cape, thus the nickname, “the widow bird.”

Magpie-Jay Flocks Are Led by Females Jul 26, 2023

Found in much of Central America, White-throated Magpie-Jay flocks are family groups led by a dominant female. They include a mate and several female offspring that bring food to the primary female and her young. It’s an example of cooperative breeding, when birds other than the parents help out to raise young.

Birds, Nests, and Camouflage Jul 25, 2023

Bird nests can be hard to find, often hidden in plain sight. Is the clever camouflage simply the result of using building materials that the birds happen to find? A Scottish research team used birds popular in the pet trade, Zebra Finches, to try and find out. The team gave nesting Zebra Finches two sources of paper to build their nests from: one that matched the papered walls of their cage, and one that did not. By and large, the finches built nests that blended in with their background.

Great Blue Herons on Land Jul 24, 2023

Throughout much of North America, the Great Blue Heron graces waterways, ponds and lakes. They’re built for hunting fish and amphibians along the water — so it might be a surprise to see one stalking across a field, not a drop of water in sight! But sometimes herons leave the water to pursue prey on land, like big insects, frogs, and even small rodents.

Birds in Summer - The Heat of the Day Jul 23, 2023

Just a few weeks past the solstice, and the real heat of summer is yet to come. Some shorebirds are already on their way south, but most songbirds will be here for a while longer. What's the best time of day to look for them? Many birds are most active in the early morning, taking advantage of the abundance of insects at that hour. Midday heat sends people inside, and birds take a siesta, too. And then, both birds and bugs rev up again in the late afternoon. But hummingbirds and also gulls — including this Glaucous-winged Gull — forage all day long!

Nest Boxes Help Bring Birds Back Jul 22, 2023

Wherever you live, chances are a sweet-singing, cavity-nesting bird would be happy to perform in your yard — and it might stick around if you offer it a cozy nest box, like the one this Carolina Wren enjoys. Natural cavities, like old woodpecker holes, are often in short supply. So putting up a box in the right place — and that’s the right size to accommodate them — is truly an act of stewardship.

Architecture for Avians Jul 21, 2023

During her first year at the Yale School of Architecture, Kenyan graduate student Barbara Nasila was tasked to design a hypothetical outdoor pavilion in a local neighborhood called Dixwell, featuring an original copy of the enslaver John James Audubon’s book, The Birds of America. As Barbara got to know Dixwell, she realized that there was already an existing conversation about birds in the community. She designed an urban oasis with bird habitat and space for community groups — but she left out The Birds of America, feeling that Audubon wouldn’t have cared about this project.

The Value of a Dust Bath Jul 20, 2023

It might sound strange, but dirt helps birds scrub themselves clean. Birds of all sizes (like the Eurasian Skylark seen here) often scrape a depression in the ground and flick dirt onto their bodies, shimmying to shake it off. Experiments showed that birds use dust to prevent oils from building up on their feathers and to remove dandruff — much like humans using shampoo in the shower!

Song Neighborhoods Jul 19, 2023

Birds of the same species don’t always sing exactly the same as each other. But those that live near each other sometimes have similar songs. Scientists refer to this pattern as a song neighborhood. It’s less like a regional dialect among people that’s found over a large area. It’s more local than that, like a group of friends copying each other's mannerisms.

What Makes Feathers Both Strong and Light Jul 17, 2023

Bird feathers are famously light, but they’re also strong, holding up under tricky flying and high winds. They’re made of beta keratin, a tougher version of the keratin that makes up human fingernails and hair. They also have an intricate branching structure that makes them highly flexible and free of unnecessary weight.

How Toucans Stay Cool Jul 16, 2023

The Toco Toucan of South America has evolved to stay cool in the sweltering heat of the tropics. Relative to its body size, the Toco Toucan has the largest bill of any bird in the world, accounting for a third of the body’s entire surface area. It’s also laced with blood vessels and wholly without insulation — features that make it a superb structure for getting rid of excess body heat.

Milkweed: A Whole Ecosystem on a Plant Jul 14, 2023

Milkweed plants are important to Monarch butterflies, which depend on milkweed to raise their caterpillars. But Monarchs aren’t the only ones who benefit from milkweed. Scientists once documented hundreds of insect species they found eating some part of the common milkweed plant – including 132 species of beetles alone. When it’s part of a diverse community of plants, milkweed helps many species find food and shelter, including birds.

Why Do Owls Bob Their Heads? Jul 13, 2023

If you were to stand face to face with an owl, including this Great Gray Owl, it would eventually move its head, bobbing rhythmically from side to side, then forward, then back. Or almost completely upside down. This head-bobbing action helps make up for an anatomical limitation: an owl’s eyes are fixed in position — they can’t move the way a human’s eyes do. The owl’s varied head movements help it judge the position and distance of things around it — essentially, to triangulate on objects, including potential prey. And to build a composite picture of its surroundings.

Grounded Geese Jul 11, 2023

In spring and summer, the paths around local ponds might have some fluffy obstacles: young goslings along with their caring and defensive parents. Adult Canada Geese lose their flight feathers for several weeks in the summer, often while they’re raising a brood of goslings. Without the ability to fly away from people, and with their young to protect, grounded geese may act especially territorial. Fortunately for a growing family of geese, newly-hatched young are able to swim and even dive underwater within just 24 hours.

Just Whose Ducklings Are Those? Jul 09, 2023

It’s spring, and a female duck swims across a pond with ducklings in tow. Some of the youngsters might not be her own. Wood Ducks and others may lay some of their eggs in other ducks’ nests — or in the nests of other kinds of ducks, like Common Mergansers and goldeneyes. Biologists call this nest parasitism or egg dumping. Perhaps it’s a kind of insurance against the loss of a nesting female’s own eggs or brood. Hooded Mergansers, like this one, are frequent recipients of eggs from other species. It’s a good bet that mother duck has at least one – and maybe more – foster ducklings.

How Birds Produce Sound Jul 08, 2023

Nearly all birds produce sound through an organ unique to birds, the syrinx. In many songbirds, the syrinx is not much bigger than a raindrop. Extremely efficient, it uses nearly all the air that passes through it. By contrast, a human creates sound using only 2% of the air exhaled through the larynx. Birds whose syrinx is controlled by only one set of muscles have a limited vocal range. This Song Sparrow, using several pairs, can put forth a cascade of trills and notes.

The Elegant Black Tern Jul 06, 2023

Elegant Black Terns breed in summer on secluded wetlands across the northern states and Canada. Because of major losses of wetlands in their breeding range — especially in Canada's prairie provinces — Black Tern numbers have dropped dramatically since the 1960s. The future of this beautiful bird depends on protecting and restoring high-quality wetlands. Recent research shows that artificial nest platforms can enhance the terns' breeding success.

Bald Eagles’ Daredevil Cartwheel Flight Jul 04, 2023

Two eagles locking talons high above the ground might look like they’re risking injury, but it’s a normal courtship behavior called the “cartwheel display.” Fully entangled, the two birds begin spinning to the earth, disengaging just before they smack the ground. Their clasp could last for hours. At last, the eagles unlock talons and fly off. Rival adults sometimes perform the same flight.

Keeping litter off the shore helps make sure that birds don’t pick up plastic and other waste and try to feed it to their young. Staying out of dunes and marked-off areas where birds are known to nest ensures that people can share the beach with birds and their young for years to come.

Megapodes - Mound-Builders Jul 02, 2023

There’s a group of birds that lay their eggs underground — in geothermally heated burrows, or warm sands, or even mounds of organic material warmed by the heat of decomposition. These megapodes or mound-builders — like this Australian Brushturkey — are found in Australia, New Guinea, and nearby islands. The male builds a mound and adjusts the amount of material to maintain a constant temperature. After a long incubation, the eggs hatch and the chicks claw their way to the surface. They never know their parents, but emerge fully feathered and capable of flying and feeding themselves.

While nearly a third of North American bird species are in decline, many birds that depend on wetlands are thriving. Duck breeding populations in 2009 were an estimated 25% above historical averages. Conditions on the breeding grounds have improved since the drought years of the 1980s, but human action has also made a huge difference. You can help by purchasing a duck stamp every year. Adam Grimm's painting of a pair of Canvasbacks won the contest for the 2014-2015 duck stamp.

The Color of Birds' Eyes Jun 29, 2023

Peer into the world of birds, and eyes of many different colors peer back. While eye color isn’t tied to one group of birds or another, a common pattern is a change in eye color as immature birds grow to adulthood. Bald Eagles, Ring-billed Gulls, and ducks such as goldeneyes and scaup have brown eyes as youngsters, and yellow eyes as adults. Red-tailed Hawks reverse this pattern, with their eyes changing from yellow to brown. And the yellow eyes of a young Cooper’s Hawk, pictured here on the right, turn deep red as they reach maturity.

Tree Swallows and Feathers Jun 26, 2023

Tree Swallows glisten in the June sunlight, as they swoop and glide, their arcs interlacing in the air. When a white feather flutters down among them, one swallow snatches the feather in its bill and flies upward, as another gives chase. After a moment, the lead bird lets loose the feather, which drifts lazily, until the second bird swoops to catch it in midair. Loose feathers are important for Tree Swallows. They line their nests thickly with them.

How Many Eggs to Lay? Jun 25, 2023

When nesting, most birds lay a predictable number of eggs. Bald Eagles: 2. Bluebirds: 4 to 6. Mallards: 10 to 12. But how do they determine when they have laid the right number? To find out, scientists experimented by going to nests and repeatedly removing eggs soon after they were laid. Some birds replaced them straight away. For example, a House Sparrow laid 50 eggs in a row, while a flicker laid 71 eggs in 73 days. But for other birds, the scientists’ removal of the eggs had no effect at all.

California Condor Jun 20, 2023

During the days of mammoths and saber-toothed cats, California Condors thrived over much of the continent. Today, they're one of the most endangered birds in the US. The condor's main survival problem is high mortality due to lead poisoning. Condors eat animal carcasses, often containing lead from hunter's bullets. California law now requires hunters to use non-lead ammunition in the condor's home range - a change that could enable condors to once again thrive, and soar, in the wild.

Baby Birds Move Out of the Nest Jun 17, 2023

After they leave the nest but before they take flight, many baby birds - especially robins and flickers - spend time on or near the ground. If you see such a baby bird, and your first thought is to "rescue" it, the better thing to do is let it be. Protect it from cats. Then watch from a distance, to see if an adult comes to feed it.

If a bird or other animal is truly sick or injured, locate your local wildlife rehabilitator.

Why Do Birds Flick Their Tails? Jun 13, 2023

The way that some birds flick, wag, or flare their tails can be distinctive. A flicking or flashing tail might suggest to a predator that a bird is particularly alert or hard to catch, while also warning others in the flock of danger. Tail flicking can also help flush out prey. A Hooded Warbler -- or a Song Sparrow, like this one -- may flare its tail while foraging low to the ground to cause insects to jump, making them easier prey.

Gull-billed Tern Jun 12, 2023

The Gull-billed Tern are terns with black caps and unusually thick bills– like a gull. This lets them eat more types of prey than other terns that rely on fish. Gull-billed Terns tackle crabs and lizards on the ground, catch flies, and even steal chicks from other birds. They’re found across the coasts of Central and South America and Southeastern US and California. The U.S. Fish and Wildlife Service considers the species a Bird of Conservation Concern due to boating or construction work near their nesting colonies.

Marsh Voices at Sunrise Jun 11, 2023

In marshes across the country, birds awaken on a summer morning. Tall dense grasses and reeds often make marsh birds hard to see, but their voices carry easily across the lush, green landscape. You can hear birds like the Redhead, the Sora, the American Bittern, the Ruddy Duck, this Yellow-headed Blackbird, and many more.

Dry Tortugas Archipelago Jun 10, 2023

From a bird's perspective, the Dry Tortugas, a cluster of islands in the Gulf of Mexico, can be a life-saver. Millions of migratory songbirds fly north across the Gulf and Caribbean each spring, headed for North America. If they run into heavy wind and rain blowing down from the continent, the Dry Tortugas provide their first landfall. In a storm, thousands of storm-tossed birds – warblers, thrushes, cuckoos, and others – seek shelter on the Dry Tortugas. No doubt that this Blackpoll Warbler was happy to touch down here!

An Unlikely Burrowing Owl Boomtown Jun 08, 2023

The Umatilla Chemical Depot in Oregon, a landscape dotted with a thousand concrete bunkers, may not look like an ideal haven for birds. But the site has taken on a new life — as a luxury subdivision for Burrowing Owls. That’s thanks in part to David H. Johnson, the founder of the Global Owl Project, who helped create Burrowing Owl “condos” by burying plastic buckets at the site.

'Akē'akē Jun 06, 2023

Known locally as 'Akē'akē, the Band-rumped Storm-Petrel is one of the smallest and rarest seabirds that nests in the Hawaiian Islands. To protect the nests of these rare birds, scientists have to find them… but it’s not easy finding a nest burrow tucked into the mountainside. That’s why wildlife biologists such as Michelle Reynolds get help from “detector dogs” specially trained to sniff out 'Akē'akē nests.

Insects Are Essential Jun 04, 2023

Insects sustain our ecosystems, as a food source and pollinators of 90% of all plants. But their numbers have dropped by half in the last 50 years, so it is now critical to help foster insects. One concrete way to help is to grow native plants that provide food and shelter for insects like caterpillars. Growing such plants directly benefits birds and helps insects keep the natural world ticking.

How the Woodcock’s Journeys Connect Us Jun 03, 2023

In this show, Marcus Rosten shares his involvement in a study of the American Woodcock with the New York State Department of Environmental Conservation. The study revealed the surprising journeys of one of North America’s quirkiest birds. One woodcock caught near Buffalo flew nearly 400 miles south without stopping, en route to spend the winter in North Carolina. Migrations like the woodcocks’ help connect people all over the continent and highlight the importance of making sure these birds can find safe places to live throughout their range.

City Gulls - Rooftop Nesters May 27, 2023

Juvenile Glaucous-winged Gulls are taking flight over downtown Seattle. In Chicago, young Ring-billed Gulls are heading for Lake Michigan. And before long, juvenile Herring Gulls will be soaring over the Atlantic Ocean. More and more, some gulls are raising their families in the city. They nest on flat, sunny rooftops that are generally inaccessible to humans. When chicks like this Western Gull fledge, they’re soft brown, and won’t have adult plumage – that flashy white and gray or black crispness – until they’re four years old.

Voices and Vocabularies - Robin's Evening Song May 23, 2023

During the day, an American Robin, a member of the thrush family, sings a lovely, familiar song of rich phrases. But as the sun begins to set, robin song takes on a different character. From sunset until dark, a robin adds ethereal whispered notes to its carol, creating a song of remarkable grace and complexity. In the high latitudes, where twilight lingers late into the evening, a robin may expand its daytime carols into a twilight symphony that continues for hours.

Voices and Vocabularies - Songs Long and Short May 22, 2023

When a Sage Thrasher, perched on a clump of sagebrush, tips its head back to sing, the notes rush forth. They often sing non-stop for at least two minutes. In stark comparison, the song of this Brewer’s Blackbird lasts barely a second. And the Henslow’s Sparrow values brevity even more. But whether they’re long and drawn out or short and sweet, bird songs are all about the same things: territory and breeding.

Drinking on the Wing May 21, 2023

Many birds drink while standing — dipping their beaks into a pond or birdbath, taking a beakful, and then tossing their heads back to swallow the water. But drinking on the wing suits swallows best. They walk awkwardly on the ground, and their long wings are cumbersome. So it’s far more efficient to grab a drink on the glide. This adaptation holds true for some other birds, too, including Common Nighthawks and swifts. Swifts have such short legs that they never land on the ground — so a sip on the wing is essential.

Come winter, these lovely songbirds head south, where they fit right in with the other brightly colored tropical birds they’ll spend the winter with in Mexico and Central America.

Chickadees Clean Up After the Youngsters May 12, 2023

Imagine this Black-capped Chickadee flying toward its nest, carrying fresh insects for its chicks. A moment later, it emerges with a tiny white pouch in its bill. The chickadee drops the object into the vegetation below. That outgoing payload is a fecal sac, a remarkable adaptation found in nesting songbirds. Nestlings — often within seconds of being fed by an adult — excrete waste in tidy little sacs. Then the dutiful parent switches tasks, from meal delivery to waste management.

A Drive Along on a Bar Ditch May 06, 2023

In the rural Southeast, roadside ditches – known as “bar ditches” – carry on for miles. The term bar ditch probably comes from their construction, when dirt was "borrowed" to build up the road. The ditches are full of water and full of life, these narrow wetlands. Herons stalk the shallow water, stabbing at minnows. Common Gallinules, like this one, swim on the surface. Reeds and bulrushes provide cover for secretive marsh birds like King Rails. Red-winged Blackbirds flash crimson epaulets as they sing, and Boat-tailed Grackles offer their own rough music.

A Yellowhammer, a European bunting, may sing over 3,000 times a day. But the Yellowhammer doesn't even come close to the North American record-holder, this Red-eyed Vireo. One such vireo delivered its song over 22,000 times in ten hours!

Piping Plovers are tiny, sand-colored shorebirds that nest on the beach. They’re threatened in much of their range. But plovers have gotten a boost from something rather surprising: hurricanes. Superstorm Sandy left behind plant-free, sandy beaches on barrier islands in New York and New Jersey, which actually offers better camouflage for nesting plovers. Where these hurricane-created habitats were protected, Piping Plovers have boomed.

No one reported another sighting until 2010. They became a “lost” species, eluding every attempt to find them. Then in 2022, Yurgen Vega was studying the birds of a mountain range called the Sierra Nevada de Santa Marta. He snapped a photo of an unusual, large hummingbird – and the sabrewing was lost no more.

White-throated Swifts Apr 24, 2023

A pair of White-throated Swifts twists and turns, sailing through the air. Dashing headlong across the canyon toward an unyielding wall, the birds disappear at the last second into a slender crevice. This swift is aptly named — and doubly so. The White-throated Swift is among the fastest of all birds. And its lyrical, scientific name suits it perfectly: Aeronautes saxatalis - sailor of the air who dwells in the rocks.

The Early Bird Apr 23, 2023

We've all heard that the early bird gets the worm. But research shows that birds dining early and heavily may lower their life expectancy. Socially dominant birds stay lean (and agile at avoiding predators) during the day, and then stoke up later, before a cold night. Subordinate birds have to look for food whenever and wherever they can find it, and carry fat on their bodies to hedge against unpredictable rations.

The Legendary Phoenix Apr 22, 2023

The ancient Greeks and Egyptians described a mythical bird called the Phoenix, a magnificent creature that was a symbol of renewal and rebirth. According to legend, each Phoenix lived for 500 years, and only one Phoenix lived at a time. Just before its time was up, the Phoenix built a nest and set itself on fire. Then, a new Phoenix would rise from the ashes.

What’s a Field of Grass to a Bird? Apr 21, 2023

Although a field of grass might not seem like valuable habitat at first, many birds have adapted to nest in grassland habitats and nowhere else. In North America, birds such as the Bobolink seek out grasslands to raise their young, deftly hiding their nests within the dense vegetation. Very few grasslands and savannas have been protected compared to the area that’s been lost, making them the most at-risk ecosystem on the planet. That means every acre of grassland remaining is even more precious — to birds, to plants, and to people.

House Wrens and Dummy Nests Apr 20, 2023

There may be no busier bird during the nesting season than a male House Wren. Just a day or so after completing his spring migration from the tropics, the male House Wren claims a territory and checks out several potential nest cavities. And in each of these locations, he builds a starter nest using virtually anything twig-like to get the job done — from nails and bits of wire to paper clips and hairpins. The male House Wren stays at it until a female pairs with him. Then she picks one of the starter nests and takes over construction.

Raising the World’s Deadliest Bird Apr 19, 2023

You might think the first bird species that humans raised in captivity would be a relatively small one, like a chicken. But evidence suggests that people in New Guinea reared the cassowary, often called the world’s deadliest bird, as much as 18,000 years ago, long before the domestication of chickens. The remains of cassowary eggs and bones at archaeological sites in New Guinea indicate that people gathered the eggs, possibly allowing the more mature eggs to hatch into chicks.

Spring Migration Across the Globe Apr 18, 2023

Each spring, millions of birds head north. From Ecuador, beautiful Scarlet Tanagers fly to the eastern US and Canada, many traversing the Gulf of Mexico, an arduous journey. Across much of southern Europe, Common Nightingales – small thrushes with russet feathers – are arriving, having traveled northward from Africa across immense deserts. In northern Asia, petite songbirds known as Siberian Rubythroats — like this one — are arriving en masse, some winging their way across the South China Sea from the Philippines, others over the mountains from Thailand.

Great-tailed Grackle Apr 17, 2023

Great-tailed Grackles live up to their name. The glossy black males trail their long, V-shaped tails behind them as they fly, almost like a plane towing a banner ad. And while not quite as flashy, the brown-feathered females have impressively long tails, too. Also known as the Mexican Grackle, this species lives in all sorts of habitats from the northern coasts of South America to the western U.S. Their ability to live in both cities and farmland has helped Great-tailed Grackles expand as far north as Iowa.

Brewer’s Sparrow, Sagelands Singer Apr 16, 2023

One of the most musical and complex bird songs in the US is that of the Brewer's Sparrow. It's a veritable aria, ringing forth from the sagebrush of Eastern Washington's Columbia Basin. Shrub-steppe is disappearing from the interior west as it is cleared for irrigated crops. The quintessential drylands bird, the Brewer's Sparrow can survive for an extended period of time with no supplemental water, getting all the water it needs from seeds and arthropods.

Magpies Help Each Other Remove Tracking Devices Apr 13, 2023

Tracking birds can be tricky — even with GPS technology. Around 70% of bird species are just too small to carry a GPS battery. But recently, Australian scientists developed GPS trackers that looked like little backpacks, weighed less than a gram, could charge wirelessly and could be quickly released with a magnet. When the researchers tested the trackers on Australian Magpies, though, the birds managed to pinpoint a tiny weak spot in the backpack and helped each other peck the trackers off. This showed evidence of altruism, a rare behavior among birds.

A Kettle of Vultures Apr 11, 2023

In the daytime, hot air rises as the sun heats the ground. The rising column of air is called a thermal, and it’s the perfect way for a Turkey Vulture to hitch a ride. Like an elevator to the skies, the thermal gently wafts the vultures upward. They move in a slowly ascending spiral around the thermal, rarely flapping and instead coasting on the breeze. When many vultures ride the same thermal, it’s called a kettle.

The Ruby-crowned Kinglet Tunes Up Apr 10, 2023

The Ruby-crowned Kinglet is one of the smallest songbirds on the continent, weighing in at just a little more than half a chickadee. Mostly green and hard to spot, it hovers in mid-air as it catches tiny insects. In early spring, the kinglet's rollicking song echoes from the forest edge in the lowlands. By late May, he is singing and nesting at mile-high altitudes in mountain forests.

Nest Building Apr 09, 2023

Want to try building a nest? Consider this... An average American Robin weighs less than three ounces. An average person weighs 170 pounds, or 1,000 times as much as a robin. A robin's nest, made of grass and mud, weighs about seven ounces, so yours will weigh 450 pounds. You'll need to collect about 350 strands of grass, each about four feet long. And don't forget the mud: 150 pounds of it. You have five days to complete the job. That's 300 mouthfuls of mud.

Cuckoos - Tent Caterpillar Birds Apr 08, 2023

One of two species of cuckoos in North America, the Yellow-billed Cuckoo, pictured here, lives in broadleaf forests throughout the East and riparian stands in the Southwest. They were common breeding birds in the Pacific Northwest as late as the 1920s, but then they disappeared. The Black-billed Cuckoo is a more northerly species that lives in dense woodland, even conifer forests. Cuckoos perch quietly and scan their surroundings for food. Hairy tent caterpillars, shunned by most birds, are often on their meal ticket.

From Bobwhite Coveys to Pairs Apr 07, 2023

Throughout winter, Northern Bobwhites gather in groups called ‘coveys’ to search for food during the day and share warmth at night. These small quail arrange themselves in a circle, with their tails in the center and heads outward, huddled up like a wreath of plump birds to survive frost and snow. But as spring arrives, the coveys disband and bobwhites seek out mates. Males whistle from shrubs and tufts of grass, hoping to catch the attention of a female.

Monk Parakeets Apr 06, 2023

If you live in the U.S., parrots might seem like ambassadors from far-off rainforests. Especially since the Carolina Parakeet, a native species once common in the South and Midwest, went extinct in the early 20th Century. But more and more parrots are finding a home here. Since the 1960s at least, Monk Parakeets have been free-flying and reproducing in the U.S. Over twenty introduced parrot species are now nesting in the US, with hotspots in Florida and California.

Camille T. Dungy on Nature and Motherhood Apr 05, 2023

Writer Camille T. Dungy’s book Trophic Cascade deals with themes of nature and becoming a mother. The title is an ecological term, referring to the far-reaching changes on an ecosystem caused by the removal or introduction of a top “trophy” predator. In the case of Camille’s book, that “trophy creature” is her daughter. Camille performs three poems from Trophic Cascade reckoning with these changes to her own ecosystem.

Rapid Evolution in the Galápagos Islands Apr 04, 2023

Scientists have long thought that new species took a very long time to emerge. This thinking has now changed dramatically. On an island in the Galápagos, researchers Rosemary and Peter Grant discovered that a hybrid union of two distinct species of finch produced descendants different from any of the island’s known species — and the speciation happened in just two generations.

Kari Sasportas on Advocating for Autistic Birders Apr 03, 2023

For Kari Sasportas, who helps lead the Feminist Bird Club of Boston, birding is a way to become absorbed in the sensations of the outside world — something that can be difficult for them to do elsewhere as an autistic person with an auditory processing disorder. Kari advocates for making the birding world more accessible for neurodivergent people. While they have seen programs designed specifically for autistic children, Kari says it’s important to ask autistic adults what they want from birding, too.

Kingbirds Steal from Wasps Mar 29, 2023

Kingbirds are robin-sized flycatchers that excel at plucking insects from the air. They’ll even tackle prey as big as cicadas. Finding naturally-camouflaged cicadas hidden among the leaves is hard work. But two species of kingbirds in Arizona found a shortcut — stealing them from cicada-killer wasps! The female wasps, nearly two inches long, paralyze cicadas and bring them to their burrows for their young to eat. The kingbirds have learned to ambush wasps carrying cicadas on the way back to their burrows.

Robins and Earthworms: The Backstory Mar 28, 2023

When glaciers pushed south into what is now the U.S. around 20,000 years ago, they scraped off the soil layer and spelled the end of native earthworms except in the southern states. So the earthworm plucked by the robin in the park or on your lawn is probably a relatively new arrival, most likely a species Europeans conveyed to the Americas in plant soil or the ballast of ships.

Melanin Makes Feathers Stronger Mar 23, 2023

Many species have black feathers on the trailing edge of their wings, regardless of what color most of their feathers are. Birds as different as gulls, pelicans, storks, and flamingos all have black-tipped wings. These flight feathers are rich in a pigment called melanin. But melanin doesn’t just provide color. It also helps make feathers stronger. Feathers with melanin have a tougher layer of keratin, the same substance found in human fingernails, compared to feathers without. So the black feathers actually help protect a wing from wear and tear.

Birds Expanding the Human Imagination Mar 22, 2023

Glenn Albrecht grew up in a “bird lover’s paradise” in western Australia. But when he saw how coal mining displaced communities, polluted the air and water, and decimated bird populations, Glenn lacked the words for his emotions. He created the concept of ‘solastalgia’ to describe the pain of witnessing environmental harm where you live. He imagines a possible future era, called the ‘Symbiocene,’ when human activity will, once again, be fully interconnected with the ebb and flow of the rest of nature and therefore cause no more destruction of life on Earth.

Spring Bursts Forth Mar 20, 2023

People often say that spring “bursts” forth. But this seasonal change isn’t like flipping a switch. It’s more like a series of waves breaking slowly. Robins and bluebirds return north in March. During April, more songbirds migrate north from the tropics, adding to spring’s growing chorus. As late as June, birds such as Willow Flycatchers and this Mourning Warbler arrive from South America. By this time, those early robins may be feeding their second brood. For them, spring has been bursting for over three months.

American Woodcock Mar 19, 2023

At sunset, the male American Woodcock - a plump, robin-sized bird - walks slowly on short legs from the cover of the forest to a nearby clearing. After a few sharp calls, the woodcock takes flight. As it spirals upward, slim, stiff feathers at its wingtips create a curious twittering. At the apex of its flight, the woodcock circles, then descends in a slow spiral, putt-putting like a tiny car about to run out of gas. The woodcock's odd looks and sounds have earned it many colorful nicknames. The most memorable? Timberdoodle!

Zone-tailed Hawks Mimic Vultures Mar 18, 2023

Zone-tailed Hawks of the American Southwest look a lot like Turkey Vultures. And they often soar among groups of Turkey Vultures. By consorting with vultures, Zone-tailed Hawks gain a distinct advantage as predators. While doves and lizards would quickly flee the flight silhouette of a Red-tailed Hawk, they seem to ignore the shadow of a vulture overhead. So floating among the vultures, Zone-tailed Hawks can sneak up on their prey undetected.

How Do Birds Brake from Flight? Mar 15, 2023

Birds are often admired for their ability to fly. But braking just in time to avoid a crash landing is amazing by itself. How does a robin go from full-out flight to a dead stop at a tree? If we could watch in slow motion, we’d see it raising the angle of its wings higher and higher from the horizontal. A hawk dives a bit below where it wants to perch, then pulls into a steep climb, slowing its momentum. And this female Wood Duck will use a combination of raised wings and a bit of hydroplaning with her wide, webbed feet to land on water.

Drumming with Woodpeckers Mar 12, 2023

Like a jazz player beating out a drum roll, a woodpecker uses its bill to rap out a brisk series of notes. Early spring resounds with the percussive hammering of woodpeckers. Their rhythmic drumming says to other woodpeckers, "This is my territory!" We also hear them knocking on wood when they carve holes in trees to create nest cavities or reach insects. For any woodpecker, it’s all about proclaiming a signal as far and as loud as possible. Look for Yellow-bellied Sapsuckers, like this one, in the Northeast and farther north, and Red-breasted Sapsuckers in the West.

Bushtits Mar 11, 2023

Weighing about as much as four paperclips, Bushtits are smaller than many hummingbirds. And they take full advantage of their diminutive size. While larger insect-eaters forage on the upper surfaces of leaves, Bushtits hang beneath them, plucking all the tiny insects and spiders hiding out of sight. They pair off to nest. (This male Bushtit is working on his nest.) Where they live in Western suburbia, a flock of Bushtits can help rid a garden of harmful aphids and scale insects.

The Chihuahuan Meadowlark Mar 10, 2023

In 2022, ornithologists recognized the Chihuahuan Meadowlark as a separate species rather than a subspecies of the Eastern Meadowlark. Named after the northern region of Mexico where they're easy to find, Chihuahuan Meadowlarks live in dry desert grasslands. They form a distinct population in Mexico and the southwestern U.S., and have a song that sets them apart from other meadowlarks.

The Delightfully Odd Magellanic Plover Mar 09, 2023

The Magellanic Plover is known for being a bit of an oddball. These shorebirds have a round body like a dove and even feed their young with milk produced in a part of their digestive system called the crop — a rare trait they share with doves. But genetic data revealed that Magellanic Plovers are neither plovers nor doves — they’re the only species in the family Pluvianellidae. Genetically speaking, they’re one of a kind.

The World's Most Abundant Bird Mar 08, 2023

An estimated 1.5 billion Red-billed Quelea live in Africa today, making them the most abundant of all wild birds. The sparrow-sized Red-billed Quelea flock together in groups so large, from a distance they appear to be clouds of smoke. Red-billed Quelea are in the weaver family and create tens of thousands of carefully woven nests in their enormous colonies.

Black Swifts Reach for the Moon Mar 07, 2023

Tracking devices revealed that Black Swifts spent over 99% of their time in the air during the winter, almost never touching the ground for months. What’s more, the swifts flew to incredible heights, reaching the highest altitudes on nights when the moon was full – sometimes over 13,000 feet! It’s the first time scientists have seen birds changing their altitude along with the cycles of the moon.

Adaptations for Flight Mar 06, 2023

Birds evolved not only wings, but many other adaptations that make it possible to fly. Feathers provide insulation, waterproofing, and a lightweight means to become airborne. Birds have honeycombed or hollow bones, reducing body weight. And instead of weighty jawbones and teeth, birds evolved a light and serviceable beak made of keratin. Most birds consume energy-packed foods rich in calories – like seeds, fruits, and meat, which add as little as possible to a bird’s payload. And what they eat is processed rapidly, so they aren’t weighed down by waste.

Birds Move from Fresh to Salt Water Mar 05, 2023

To hear a Common Loon in the wild during summer, you’ll need to find a northern, freshwater lake where a pair is nesting. But to find that same Common Loon in winter, you’ll likely need to look on a saltwater bay. This shift from fresh to salt water would kill most animals. But loons — along with many ducks and other water birds — have evolved to make that move. It’s possible that breeding adults nest on fresh water in order to save their energy for raising chicks.

Sage Thrasher and Sagebrush Mar 04, 2023

The glorious song of the male Sage Thrasher rings out every spring from tracts of sagebrush throughout the West. Sagebrush was once widespread in the Great Basin region, and so were the thrashers. But huge areas of sagebrush were turned into alfalfa and potato farms, and the songs of the thrasher aren't so common today. Sagebrush badly needs advocacy. The Important Bird Areas program works to protect key habitats for birds.

To Beta or Not to Beta Mar 03, 2023

Male Lance-tailed Manakins pair up to perform choreographed courtship displays for females. Known as cooperative courtship, it involves one alpha male and one beta male, who are not closely related, working together to attract the female. While it might not seem like a good deal for the beta male, the betas gain experience in courtship that could come in handy when they attain alpha status.

Diving Birds Are Dense Mar 02, 2023

While many birds have hollow bones that make flying a breeze, diving birds are built differently. The bones of divers such as Common Loons are denser than those of songbirds and other expert fliers. With a lightweight skeleton, they’d be too buoyant to dive and chase fish. Instead, loons can kick their powerful legs and webbed feet to swim 200 feet or more underwater!

Dreading the Terns Feb 28, 2023

In June of 2022, Adé Ben-Salahuddin worked as a volunteer research assistant on a tiny island off the coast of Maine at a Common Tern breeding colony. Every once in a while, the colony would suddenly go dead silent as all the adult terns took flight and dove over the rocky cliffs, returning soon afterward. This strange behavior is called a “dread,” and sometimes occurs without a predator nearby. It remains unclear why terns do it.

Northern Saw-whet Owl - A Bird with a Lot to Say Feb 27, 2023

For such a small owl, the Northern Saw-whet has a lot to say. And a lot of ways to say it. Males weigh about as much as an American Robin. And they send out at least 11 different calls, including “toot-toot-toot” advertising calls, from late January through May. The rate of calling is partly determined by the nighttime temperature. And perhaps to keep other Saw-whets out of a food-rich territory, males may toot more frequently when their favorite prey, white-footed mice and deer mice, are plentiful.

Rough-legged Hawk Feb 26, 2023

After breeding on Arctic cliffs and tundra hillsides in summer, Rough-legged Hawks winter throughout the Northern Hemisphere. Open country is their ideal territory, where the small rodents they depend on are usually so plentiful that the hawks have enough to eat. But the rodents are cyclic, with lower populations in some years, and in those winters, Rough-legs may migrate farther and be more abundant in the contiguous United States.

Common Eiders Favor Close Relatives Feb 25, 2023

Some species of birds try to save energy by tricking others into incubating their eggs. But if the parasitic female is a related species, she may have an advantage. After studying the nests of Common Eiders, such as the one pictured here, researchers at the University of Gothenburg in Sweden determined that trickery among close relatives of the nest owners caused no aggression. But the attempts of unrelated females often resulted in conflict.

New Sam Peabody Feb 21, 2023

In late winter, White-throated Sparrows erupt into song, easily set to human words: “Old Sam Peabody, Peabody, Peabody.” Or “Oh, sweet Canada, Canada, Canada.” But something changed since those classic memory aids were coined. Sixty years later, the bird sings a simpler, shorter song. Bird song, like human language, changes. By the 1960s, the bird’s longer song became rare. Researchers suggested that the “classic” song had — for some unknown reason — died out, to be replaced by a shorter version.

Annakacygna – The Ultimate Bird Feb 20, 2023

Like today’s swans, the extinct species Annakacygna hajimei and Annakacygna yoshiiensis were quite large. But unlike their modern relatives, these birds lived most of their lives out at sea, and their fossils reveal remarkable adaptations to this unusual lifestyle. This led the researchers who first described these species to dub them “the ‘ultimate bird’ that ever existed.”

Wilson’s Phalarope Feb 19, 2023

If any bird is an anomaly, it’s the Wilson’s Phalarope. In a birdbook, Wilson’s Phalaropes are found among the sandpipers. But they forage while swimming. Spinning like tops, they create an upwelling, pulling food to the surface. The breeding of Wilson’s Phalaropes is anomalous, too. Females are the brightly colored sex, and courtship roles are reversed: female phalaropes compete for males, and, once they lay eggs, leave all parental duties to the males. In common with many birds, though, Wilson’s Phalaropes face conservation challenges.

The Cactus Wren’s Signature Voice Feb 17, 2023

Most wrens in North America are small, furtive birds that stay deep in the vegetation. But the Cactus Wren is large, bold, and brassy. These wrens are well adapted to the desert and can get all the moisture they need from their food. Cactus Wren nests are a regular sight in their range of dry habitats from West Texas to California. The nest looks like a football made of twigs, stuck horizontally in a thorny tree or cholla cactus. It’s easily seen but well guarded by the spiky vegetation.

Protecting the Rimatara Lorikeet Feb 15, 2023

With brilliant crimson chests, green backs and blue crests, Rimatara Lorikeets are stunning birds. The last native population of the lorikeets survives on the island of Rimatara, thanks to the foresight of the island’s last queen, Temaeva Vahine, who placed a tapu on the birds, denoting them sacred. Rimatara residents, proud of their ‘rainbow’ birds, have teamed up with the Polynesian Ornithological Society to ensure the lorikeets are here for generations to come.

For White-throated Swifts, Love Is in the Air Feb 14, 2023

For some birds, love is in the air. When a pair of White-throated Swifts wants to get to know each other, they meet up — on the wing — high above the ground. The birds grasp one another and, clinging together, tumble downward, for over 500 feet. Just before striking the earth, they separate, flying nonchalantly back up the canyon wall. Visit a Western canyon, and you might see a pair of swifts literally falling in love.

Salt Flats as Bird Habitat Feb 13, 2023

In the Salt Flats of Cabo Rojo, Puerto Rico, the Indigenous Taino people found a way to harvest salt long before Europeans arrived. But this unique ecosystem isn’t just useful for sea salt production — the salty lagoons are full of brine shrimp for shorebirds to eat. Local residents banded together to protect the salt flats as bird habitat.

Why the Black Skimmer Skims Feb 11, 2023

That’s not a distant dog barking. It’s a Black Skimmer in flight, at the Chincoteague National Wildlife Refuge in Virginia. This striking, black-and-white bird with a red bill and red feet has a most unusual way of feeding. It flies low along the surface of the water with its beak open. Closely related to terns, skimmers nest on sand islands in closely packed colonies. They depend on undisturbed islands and abundant small fish in coastal lagoons for their survival.

Small Birds Mob Big Ones Feb 09, 2023

When smaller birds join forces to ward off larger birds, it's called mobbing. This behavior — like calling your family for help — is used by many bird species. The best time to observe mobbing is spring and early summer, when breeding birds are trying to protect their nests and young. Birds including swallows, blackbirds, and even these American Crows, seen here mobbing a Red-tailed Hawk, know that there is strength and power in numbers. And they've learned to join forces to protect themselves.

The Mississippi Sandhill Crane Makes a Comeback Feb 08, 2023

While most Sandhill Cranes migrate, the Mississippi population lives year-round in wet pine savanna near the Gulf Coast. Their dependence on this unique habitat caused their population to plummet to just 35 when the savanna began to disappear. Through the Endangered Species Act, an almost 20,000- acre wildlife refuge was established for the cranes and the population has begun to recover.

Winter Birds of Southern Florida Feb 05, 2023

It’s winter in North America — a good time to head for the subtropical realms of South Florida and listen to the region’s birds, such as the secretive Mangrove Cuckoo pictured here. Rarely seen, it sings sporadically in winter. When it does, you’re sure to take notice. A sweeter voice belongs to the Spot-breasted Oriole. Found in suburban neighborhoods, these birds were brought to Florida in the 1940s from Central America. And we can’t forget the sharp-edged phrases of the White-eyed Vireo or the eerie cries of the Limpkin.

Birds Are Evolving Rapidly - Today Feb 04, 2023

House Finches are evolving rapidly and visibly. In 1941, some captive House Finches from California escaped near NYC. They spread rapidly and are now found across most of the US. We know the finches have evolved, because those that survive differ from their parents. Size is one example. Male House Finches in recently established populations are larger than the males that escaped. Females have become smaller and survive better than larger females as nestlings. Evolutionary changes are occurring visibly all around us.

Turkey Vultures and Gas Pipelines Jan 30, 2023

Do vultures detect carrion by sight or by smell? The lightbulb moment came to ornithologist Kenneth Stager when a Union Oil employee told him of vultures congregating at the spots along pipelines where gas leaks were occurring. Why would they do that? Because a key ingredient in the odor of carrion is ethyl mercaptan — the same substance companies add to odorless natural gas in their pipelines, so they could smell if there was a leak. So now we know that vultures can spot carrion by either sight or smell.

Birdhouses in Turkey Jan 28, 2023

It’s easy to imagine that putting up a birdhouse or nestbox is a relatively recent practice. But in Turkey, it has a long history. Since at least the 13th century and continuing through the period of Ottoman rule, birdhouses were placed on all sorts of structures: mosques (like this one – the Yeni Valide Mosque in Üsküdar, Istanbul, Turkey), schools, libraries, houses, tombs, bridges, and palaces. In this culture, birdhouses were viewed as an expression of love and compassion for animals. The Ottomans even endowed charities to provide food and water for birds and to care for sick birds.

If You See a Bird with Leg Bands Jan 27, 2023

If you see a wild bird with a small metal band around its leg, that means researchers have given the bird a unique ID to keep track of it over the course of its life. You can report the sighting to the Bird Banding Laboratory, a part of the U.S. Geological Survey that studies banded birds across the continent. Analyzing where and when banded birds are seen helps biologists figure out bird lifespans, migratory routes, and how their populations are changing.

Birds Winter at the Salton Sea Jan 23, 2023

California's Salton Sea is hot and smelly - and it's also a Mecca for thousands of wintering birds. This inland sea formed when the Colorado River breached floodgates in 1905, forming a lake 45 miles long. The lake has diminished in size and greatly increased in salt concentration, but a single introduced fish - the African tilapia - persists in abundance. Seabirds visit the Salton Sea to feed on them. The smell comes from occasional massive die-offs of the fish, so abundant that their bones make up the shoreline. Every winter, the salty waters support hordes of water birds, including shorebirds, herons, cormorants, pelicans, and waterfowl. Check it out!

Northern Cardinal - Meet the Cardinal Jan 22, 2023

Is there any doubt about the identity of America's best known red bird? Surely it's the cardinal or, as you'll find it in a bird book, the Northern Cardinal. The beautiful bird seen on so many bird feeders takes its name from the cardinals found in the Vatican, whose hats and robes are red. Only the male cardinal — seen right here — is red; females are a tasteful olive-brown with red highlights. Share this show with someone who likes cardinals. Thanks!

Common Poorwills Can “Hibernate” Jan 21, 2023

Common Poorwills don’t sing much when the mercury drops. But they can do something else that is remarkable. As the winter cold deepens, these petite members of the nightjar family can enter a hibernation-like state — and stay like that for hours — or even weeks! Scientists call it torpor. It happens when an animal slows its body functions to conserve energy and heat.

Woodpeckers Love Ants Jan 19, 2023

Woodpeckers, as a group, eat far more ants than most other birds do. Many other vertebrates tend to avoid ants because of their stings or because of the noxious chemicals they contain, like formic acid. But woodpeckers just love them. A Pileated Woodpecker’s diet may be up to 50% ants!

The Skatebirder Jan 18, 2023

Dave Mull is not your typical birder — he's a professional skateboarder, or a “skatebirder” as he puts it. He brings binoculars with him when he skateboards and doesn’t mind putting his board down to check out a bird. But the birds aren't really a distraction for Dave. Tuning into his surroundings, including the birds, helps him stay in the zone and provides inspiration for tricks.

Identifying a Bird in Flight Jan 17, 2023

One of the most difficult skills to pick up as a birdwatcher is how to identify birds in flight. You have to sort through a series of visual clues all at once, at high speed: silhouette, wing shape, how fast it flaps, and patterning. An experienced birder will take in all these and other clues that are hard to put into words — and might say something like: “Look! A hawk! Must be a Cooper’s Hawk — it has that giss.” In other words, it has all the telltale signs. But where did this bit of birdwatching slang originate?

Thick-billed Euphonia - Deceitful Mimic Jan 15, 2023

Northern Mockingbirds can learn to mimic the sounds of just about any bird. They mimic to show off, not to deceive. But this Thick-billed Euphonia, a tiny songbird in South America, employs what scientists call “deceitful mimicry.” When frightened by a predator near its nest, a Thick-billed Euphonia imitates the alarm calls of other birds nesting nearby. This stirs them into action as they rush in to harass the predator. The euphonia, meanwhile, sits tight while others do the dirty work.

Yellow-rumped Warbler - The Winter Warbler Jan 12, 2023

By winter, most warblers have migrated south. But the Yellow-rumped Warbler, which birders affectionately call “butterbutt” is a lesson in adaptation, notes Bryan Pfeiffer, a writer, naturalist, and educator who lives in Vermont. “In winter, when most of their kin are enjoying insects in the tropics, Yellow-rumps are finding food across parts of the West, the southern U.S. and north into New England,” he says. “With insects in short supply, the Yellow-rump turns to fruit . . .”

For some of us, it’s hard to get excited about gulls. But they are just as fascinating – and have as much to tell us – as other birds. Take the Herring Gull, for example. Its appearance is striking, and its voice is unforgettable. Along the Atlantic coast of North America, the nesting population of Herring Gulls numbers in the hundreds of thousands. But as recently as 1900, feather and egg hunters had wiped out virtually all nesting Herring Gulls south of Maine. Fortunately, conservation laws have enabled the gulls to recover.

Bohemian Waxwings Wander South Jan 06, 2023

In winter, when snow blankets the northern states, nearly all of the songbirds that graced the days of summer are gone. But there’s one special winter visitor that fills the absence: the Bohemian Waxwing. In autumn, waxwings wander south from the boreal forest into the northern states and along the Rockies. Sometimes, they venture even farther south. In fact, it’s this itinerant life that earned them the name “Bohemian.”

Corkscrew Swamp Sanctuary Dec 31, 2022

National Audubon's Corkscrew Swamp Sanctuary is birdy at any time of year. But in winter, this mixture of cypress swamp and pineland comes alive with migratory songbirds. On a warm, sunny morning, birds are active all around, from the tops of the tall cypresses to the shrubs along the boardwalk. An Eastern Phoebe, after spending the summer in Pennsylvania, calls from a dead branch over the water. A Palm Warbler, all the way from Ontario, moves through the undergrowth. And this Blue-gray Gnatcatcher, having migrated from a similar swamp in Georgia, forages in a willow. Many birds find the habitats they need in the Corkscrew Swamp Sanctuary.

The Northern Shrike breeds in the tundra and taiga of the north, but migrates south into the lower 48 for the winter. It has a pleasing and rhythmical song, which it sings even in winter. But its song belies a rather bloodthirsty feeding habit. The shrike impales its prey on sharp thorns or barbed wire, where it can pull it apart and consume it.

The Verdin’s Winter Roosts Dec 25, 2022

For small songbirds, surviving a cold winter night can be challenging. Their bodies lose heat faster than those of larger birds. So little birds have found resourceful ways to stay warm — like huddling close together with other birds. But the Verdin, a tiny bird of the Southwest, does something few other birds do to keep warm: it builds extra nests to roost in, in the winter.

Sharp, insistent cries signal the presence of one of North America’s most beautiful birds of prey: the Red-shouldered Hawk. There’s no mistaking this striking hawk for any other; the front of its body glows bright chestnut, the back boldly spangled black and white, the shoulders, that same blazing chestnut. Roughly crow-sized, Red-shouldered Hawks are found throughout the eastern U.S., retreating from the north in winter. Distinctive populations inhabit Florida and California west of the Sierra Nevada.

A Crossbill's Beak Does the Job Dec 22, 2022

A close look at this Red Crossbill reveals a curious adaptation. The long tips of the upper and lower bill don't meet, but instead cross over each other. The Red Crossbill bites between the scales of a cone and pries them apart by opening its bill, then dislodges the seed with its tongue. Red Crossbills search for cones on the tops of the trees, climbing around using their feet and bills, much like parrots. And strangely, they’ll breed in winter, if the cone crop is good enough.

Attu and Its Island-hopping Rock Ptarmigan Dec 17, 2022

Attu, at the western end of Alaska’s Aleutian chain, is home to the Rock Ptarmigan. Although grouse are not long-distance fliers, Rock Ptarmigans can cross open water, so they occur from one end of the Aleutians to the other. They are supremely adapted for high latitudes, with thick feathers, each with two shafts. During winter, even their toes become feathered. They ride out blizzards by burrowing deeply into fresh powder snow and roosting there. When spring finally arrives, the snow-white male will flutter into the air, then glide to earth while calling loudly. He fans his black tail in spectacular display before the female. And a new year begins!

The Scaly-breasted Wren lives in Central and South America, and has a lengthy song of whistled notes separated by pauses. By analyzing song recordings, researchers found that Scaly-breasted Wrens can precisely measure out pauses — even as they increase to several seconds. The findings suggest that the wrens have an internal metronome as accurate as a highly-trained musician playing a solo.

Wing-clapping Dec 07, 2022

For most birds, wings are for flying. But for Rock Pigeons, they’re also for clapping. When the pigeons erupt into flight, some may slap their wings together above their bodies in a “wing clap.” A male Rock Pigeon will also do this when courting. Short-eared Owls, like this one, have evolved wing-clapping, too. When a male displays to a female or attempts to warn off an intruder, he snaps his wings together below his body in a burst of two to six claps per second, producing a sound that sounds remarkably like . . . applause.

Puffling Patrol Dec 06, 2022

Just off the southern coast of Iceland, the Westman Islands are home to many of the country’s several million Atlantic Puffins. When puffin hatchlings, known as pufflings, get confused by the lights of the city, volunteers of all ages search for wayward pufflings on the street and bring them in for health checks. After the puffins get the green light, the volunteers release them along cliffs and beaches.

Wilson's Warblers Benefit from Shade-grown Coffee Dec 05, 2022

Early this fall, the tiny Wilson's Warbler began its long migration to Belize, where it winters. Navigating by the stars, the 1/4-ounce bird made a series of night flights spanning more than 2500 miles. This warbler returns to the same coffee plantation each year. Taller trees that shade the coffee are a winter home for many migrants from North America.

By buying shade-grown coffee, you can help migratory birds, including the Wilson's Warbler.

Diving Birds – Below the Surface Dec 03, 2022

By December, an array of diving birds that nested at far northern latitudes are wintering on temperate waters across the continent. If we could watch them under water, we'd see this Common Loon racing like a torpedo. A goldeneye dives under water and swims about 10 feet from the surface, while scoters get down to 30 feet in search of clams and mussels. But if one bird stands out as the most beautiful diver, it has to be the Long-tailed Duck. Propelling itself beneath the surface with its wings, it seems to fly through the water, sometimes to depths of more than 60 feet!

Strange Places for a Nest Dec 02, 2022

Birds are resourceful. Wherever they live, even in the biggest cities, they find clever places to build their nests. An initiative from the Cornell Lab of Ornithology called Celebrate Urban Birds, once asked people to share the funkiest and funniest places they’ve seen a bird nest. Among the highlights were a family of robins set up shop in a coiled cable hung near a welding rig, a wren nest in an old car motor, and a tiny hummingbird nest perched precariously on an outdoor string lightbulb.

Are Northern Forest Owls Coming South This Winter? Dec 01, 2022

The boreal forest stretches across Canada and Alaska, a huge expanse of woods, wetlands and wilderness. And it’s full of magnificent forest owls that depend on mice and other rodents for food. Those populations can boom and bust, so in lean years, hungry owls often fly as far south as the northern U.S. to find food.

The Woodcock’s Silly Walk Nov 30, 2022

When it comes to silly walks, no bird outdoes the American Woodcock’s one-of-a-kind strut. It goes like this: take one step forward, then rock your whole torso forward and back a few times before sliding another foot forward — all while keeping your head perfectly steady. It looks like a bird with an undeniable sense of rhythm. It’s not entirely clear why woodcocks walk this way. It’s another of the bird world’s little mysteries — and one of its grooviest dance moves.

Dowitchers Get a Second Wind Nov 29, 2022

The two American species of dowitchers, Long-billed and Short-billed, are similar in appearance but have distinctive calls. And they’re some of the continent’s most dramatic songsters. On their northern breeding grounds, Short-billed Dowitchers ascend as high as 150 feet in the air then glide slowly earthward, singing. At the end of the glide, they may take off again for another bout of song.

New Homes for Cockatoos Nov 28, 2022

The alpine forests of Australia’s southeast are home to an iconic pint-sized gray parrot with a bright red mohawk, and a call that’s been described as a “flying creaky gate”. The Gang-gang Cockatoo has seen significant habitat loss in recent years, especially after the 2020 wildfires. It’s now listed as an endangered species. A new national working group is coordinating recovery efforts. Researchers and community scientists are trialing an innovation on the Gang-gang population called the “Cockatube” — a PVC tube designed to host a cockatoo nest.

Why Birds' Feet Don't Freeze Nov 27, 2022

Have you ever watched ducks walking around in freezing temperatures and wondered why their feet don't freeze? And how do birds, including this Northern Flicker, sit on metal perches with no problem? Birds' feet have a miraculous adaptation that keeps them from freezing. Rete mirabile — Latin for "wonderful net" — is a fine, netlike pattern of arteries that interweaves blood from a bird's heart with the veins carrying cold blood from its feet and legs. The system cools the blood so the little blood that goes down to the feet is already cold, so the birds don't lose much heat. The small amount that goes to the feet is likely just enough to keep the feet from freezing.

The Avocets of Bolivar Flats Nov 26, 2022

The shallow waters and wide mudflats of the Bolivar Flats Shorebird Sanctuary northeast of Galveston, Texas, are alive with thousands of gulls, terns, and shorebirds. American Avocets are often among the most abundant birds, with 5,000 or more here most winters. The avocets have sensitive bills that curve upward. As they wade, they sweep their heads back and forth and snap up the tiny crustaceans that touch their bills. This tactile feeding method is unique among the birds here. The Bolivar Peninsula is famous for its big flocks of water birds and concentrations of migrating songbirds. Both National Audubon and American Bird Conservancy have designated it an Important Bird Area, or IBA.

Spark Bird: Maya Higa and Bean Nov 25, 2022

When Maya Higa started interning at a zoo, she wasn't especially into birds — until she began rehabilitating a Red-tailed Hawk named Bean. Meanwhile, Maya was doing live-streams of herself singing and playing guitar on the website Twitch, just for fun, to a pretty small audience. The video went viral, and Maya's audience grew from there. Thousands of viewers watched Bean's rehabilitation on her streams, forming a bond with the bird. And this reminded Maya of her education work at the zoo. She has since founded the Alveus Sanctuary, a nonprofit animal sanctuary and virtual conservation education center.

Titmice Lead the Way Nov 24, 2022

In winter, many songbirds join flocks made up of multiple species that travel around looking for food, benefitting from safety in numbers. But a bird flock that doesn't move in the same direction soon scatters to the wind. It turns out that the Tufted Titmouse, a small gray songbird, is often the one leading the flock. Researchers studying the flight paths of flocks found that the paths taken by the titmice best reflected the direction of the group as a whole, compared to other species in the group. This was especially true when the flock moved quickly between sites, when staying organized is key.

Snake-Eagles Are Awesome Nov 23, 2022

When a soaring Short-toed Snake-Eagle spots a delicious snake, it swoops down, grabs it with its talons, then tears off the snake’s head. Still on the wing, it swallows the entire snake, head first. Smaller than Bald Eagles, they live mainly in Africa and have legs and toes covered in thick scales to protect them from bites. Snake-Eagles take on some of the swiftest and deadliest snakes in the world, like cobras and black mambas.

Molly Adams on Birding with Long COVID Nov 22, 2022

For Molly Adams, the founder of the Feminist Bird Club, getting COVID didn’t just mean a week or two under the weather. Like other people with long COVID, they’re continuing to have chronic symptoms after the viral infection. Fortunately, before COVID they had learned about a technique called atlasing — observing birds closely to figure out if they’re breeding in a certain habitat. The observations become part of a record called a breeding bird atlas. Molly says atlasing is a more soothing, slowed-down approach to birding and involves getting to know birds as individuals.

Bird Names in Meskwaki Nov 21, 2022

The poet Ray Young Bear writes in both English and Meskwaki, his first language. He says that the task of passing on Indigenous languages feels especially urgent now as linguistic scholars predict the loss of languages.

The Meskwaki language is rich with bird names, like Tti Tti Ka Kwa Ha, the name for the robin, which emulates the bird’s song, he says. After decades of creating poems, novels, and songs, Ray Young Bear has dedicated himself to preserving and teaching his language and culture.

Return of the Snowbird Nov 20, 2022

You may see Dark-eyed Juncos in the summer, but come fall, many more — those that have been nesting in the mountains or farther north — arrive to spend the winter. These juncos often visit birdfeeders for winter feasting. Dark-eyed Juncos forage on the ground. The flash of white tail-feathers when one is alarmed alerts other members of the flock, and is also used as part of the courtship display.

And a bill must be the right size and shape for the bird’s diet, whether that’s probing for worms, cracking open seeds, or tear apart prey.

Partial Migration - Killdeer Play Leap Frog Nov 17, 2022

The cries of a Killdeer are familiar across most of the US during spring and summer. But where do they go in winter? Killdeer that breed in the southern half of the US and along the Pacific Coast are year-round residents. But those that breed in the northern US and Canada, where winter conditions are more severe, migrate south to Mexico and Central America. Because the northern Killdeer fly south — right over the region where other Killdeer reside year-round — they are known as leap-frog migrants.

Bears at the Bird Feeder Nov 16, 2022

In bear country, food left outside or uncovered trash cans can become irresistible targets for bears looking for a quick snack. But even if you’ve put away any human food, don’t forget about bird feeders. Bears are omnivores and won’t hesitate to grab a bird seed snack. The New York State Department of Environmental Conservation recommends that people take down bird feeders between April 1st and November 30th, when black bears are most active. During the winter, the bears return to their winter dens and bird feeding can resume.

Geese in V-formation Nov 15, 2022

Autumn…and geese fly high overhead in V-formation. But what about that V-formation, angling outward through the sky? This phenomenon — a kind of synchronized, aerial tailgating — marks the flight of flocks of larger birds, like geese or pelicans. Most observers believe that each bird behind the leader is taking advantage of the lift of a corkscrew of air coming off the wingtips of the bird in front. This corkscrew updraft is called a tip vortex, and it enables the geese to save considerable energy during long flights. The V-formation may also enhance birds’ ability to see and hear each other, thus avoiding mid-air collisions. Small birds probably do not create enough of an updraft to help others in the flock and don’t fly in vees.

Three Worldwide Raptors Nov 13, 2022

Consider three species of raptors: the Barn Owl, Peregrine Falcon, and Osprey. They’re on every continent except Antarctica. Each has a specialized hunting prowess distinct from the other. They can fly great distances. And like many birds of prey, they mate for life. The Barn Owl, pictured here, has long been considered the single most widespread land bird in the world. But Ospreys and Peregrines have proven equally adaptable.

Boreal Chickadees Stay Home for the Winter Nov 10, 2022

Boreal Chickadees live in the boreal forest year-round. How do they survive the harsh winter? First, during summer, they cache a great deal of food, both insects and seeds. Then in fall, they put on fresh, heavier plumage. And their feathers are denser than most birds', creating a comfy down parka. Most impressive? The chickadees lower their body temperature at night from 108 degrees to just 85 degrees, conserving their stores of insulating fat. Hats off to the Boreal Chickadee, a truly rugged bird!

For biologist and writer Wenfei Tong, the line between people and animals has always felt fuzzy — or maybe feathery, in the case of birds. Wenfei loves to highlight commonalities we share with birds, like how young adult Acorn Woodpeckers sometimes stay with their parents if there aren't good territories available for them to move into right away. She thinks that seeing ourselves in birds could be a boon for conservation.

Screech-Owls Go Fishing Nov 08, 2022

Screech-owls are opportunistic diners. In the Pacific Northwest, they’ll prey on small birds, crayfish, large ants, or earthworms. In Arizona, pocket mice and pack rats. And in Ohio, biologists who noticed a fishy smell around Eastern Screech-Owl nest boxes found the remains of dozens of shad. It’s clear that screech-owls may be a consistent nocturnal predator on fish, especially in cooler months, when other prey are dormant.

Pulling Rank at the Birdfeeder Nov 06, 2022

Birdfeeders full of seeds or suet can spark nonstop action. Chickadees flitter in and out. Finches expertly crack one seed after another, while jays, doves, woodpeckers and sparrows all join the flurry. This might bring to mind a neighborly picnic — but it’s not quite as friendly. At any given moment, there’s a distinct hierarchy in effect. More dominant birds are usually able to displace lower-ranking birds. But not always! The next time you’re watching a birdfeeder, try to figure out who’s in charge.

Providing Homes to Purple Martins Nov 04, 2022

In the Southeast, on the lands of the Cherokee, Chickasaw, and Choctaw, Purple Martins nested in dried gourds hung up by Native Americans. This relationship might have developed because Purple Martins defend their turf, says Kelly Applegate, a tribal member and Commissioner of Natural Resources for the Mille Lacs band of Ojibwe. White settlers copied the practice and put up gourds and birdhouses, too. But they also cleared forests where martins once nested and introduced House Sparrows and starlings that drove them out of woodpecker holes. Purple Martins now depend almost entirely on artificial nest boxes to survive. Kelly is encouraging people to provide homes for martins.

Great Horned Owls Calling Nov 02, 2022

A fledgling Great Horned Owl calls to be fed. Judging from the young bird's persistence, the parents seem to be responding only with calls, not with food. These entreaties can go on for weeks. Both parents let the fledgling know that it's time for him to feed himself. They've been bringing voles and rabbits for months. Silence and surprise are keys to the owls' success as hunters, so it's hard to imagine the juvenile Great Horned Owl improving his chances by being so vocal!

Frigatebirds - Seabirds That Can't Get Wet Oct 30, 2022

Frigatebirds are seabirds, but one thing you’ll never see is a frigatebird floating on the ocean. Why not? Because their feathers, unlike those of nearly all other seabirds, are not waterproof. Instead, frigatebirds are masters of staying aloft. They soar above the ocean, riding a complex roller coaster of air. Intentionally flying into a cumulus cloud, which has a powerful updraft, they may rise as high as 2.5 miles into the frigid atmosphere. From this high point, frigatebirds — such as these Great Frigatebirds — can glide more than 35 miles without flapping their wings. Which is how these seabirds survive over the open ocean.

Designing a Spider Web to Evade Bird Collision Oct 29, 2022

One of the lesser known hazards of a bird’s life — when flitting from shrub to shrub — is collision with spiders’ webs. And when a bird flies through a web, it’s the spider’s hard work that takes the hit. It can take a spider an hour just to repair the damage and get on with the task of snaring its next meal. Some spiders have evolved a behavior to give birds advance warning of their webs. They weave into the structure visible designs of white, non-sticky silk, called stabilimenta. These make it easier for birds to see it — and avoid it.

The Five Birds You’re Scared Of Oct 27, 2022

Author and bird enthusiast Ashley C. Ford says that it’s good to have a list of at least five birds that you’re scared of — like the six foot tall cassowary — just to keep you honest. “It's very important to humble yourself and to understand where you actually lie on the food chain,” she says. But despite the goose’s mischievous reputation, she’d never have them on her list. “I grew up in the Midwest,” she says. “And I know personally I'm not scared of no goose.” Hear more of Tenijah Hamilton’s conversation with her birding heroes, Ashley C.

Geese Whiffling in for a Landing Oct 26, 2022

Looking at a Canada Goose, you might not think their bodies are designed for fancy flying. But watch as a flock of geese comes in for a landing at a lake and you might be surprised. If the flock comes in too fast or too high above the water, geese have a little trick to slow themselves down for a safe landing. The geese stop flapping and then quickly roll their bodies upside down, while twisting their long necks the right way up. Finally, they rotate again to right themselves just in time to gently splash down. It’s a maneuver called whiffling. It seems to help the geese slow down quickly – but sometimes it might just be for fun.

If we had to pick one bird’s voice to symbolize our Eastern woodlands, the Blue Jay’s voice would likely be it. And as a frequent visitor to back yards and bird feeders, the Blue Jay is among the most recognized birds of the region. Nearly a foot long, Blue Jays can be loud and assertive when they approach a bird feeder, pushing smaller songbirds aside. But when nesting, the same jays can sneak to and from their nests with uncanny secrecy.

Spark Bird: Kenn Kaufman Oct 24, 2022

As a young child, Kenn Kaufman ventured into his neighborhood in search of the tigers, bears, and dinosaurs, but quickly found that Indiana doesn’t have those. So he set his sights on the next best thing: figuring out which birds were in his family’s yard. Though he’s now a world renowned birder and field guide author, he says his progress was slow. Today’s novice birders have access to mobile apps and websites that put photos, bird calls, and range maps at your fingertips. But whatever tools you choose, Kenn says there’s no substitute for getting outside and experiencing the birds for yourself.

Powder Down Oct 22, 2022

Hidden below the outer breast feathers of herons, pigeons, doves, tinamous, bustards and some parrots are patches of special down feathers. These feathers are never molted, and they grow continuously. The tips break down into a dust the consistency of talcum powder. Using a fringed claw on its middle toe, a heron collects some of the dust—or powder down—and works it into its feathers. Sort of like the way you might work conditioner into your hair.

The Firebird’s Bright Outfit Oct 21, 2022

You might have heard of the Phoenix, the legendary bird who bursts into flames and is reborn from its ashes. Well, its literary cousin is the Slavic myth of the Firebird, an elusive creature whose feathers burn and light up the night. Stories about Phoenix-like birds have spread all over, and Firebird legends are found in most Slavic cultures. These stories, like connective tissue, help unite people throughout the world.

One Species Caring for Another Oct 20, 2022

In North America, the European Starling has gained a bad reputation for competing with native bird species for nest cavities. But researchers in Ontario, Canada, were surprised to see three Hairy Woodpecker nestlings receiving care from both a female Hairy Woodpecker and a European Starling — a stunning example of a bird caring for another species’ young.

Bird Sound Types and Qualities Part I Oct 19, 2022

Since it’s often hard to see a bird, veteran birders characterize the sounds of birds in order to identify them. So what words do they use? Well, they use “whistle,” for example, to describe the sound of this Olive-sided Flycatcher. And "rattle" for that of the Belted Kingfisher. There's the trill of a Dark-eyed Junco. And the House Wren's “cascade!" The song of a Downy Woodpecker is a sort of “whinny." Listen again and see if you can recognize the types of sounds.

An Inclusive Approach to Bird-a-Thon Oct 18, 2022

Bird-a-thon is Massachusetts Audubon’s biggest fundraiser. Teams of birders spend 24 hours competing to observe as many bird species as they can, to encourage people to donate. But Meghadeepa Maity, who helped organize Bird-a-thon in 2021, realized that not everyone can spend all day traveling to find birds. They started to think of other approaches. Meghadeepa, who’s also an organizer for Birdability, helped create an inclusive Bird-a-thon experience: a stationary count circle at a wildlife sanctuary. The event had a great turnout — and plenty of birds.

Team Nuthatch competed in the 2022 World Series of Birding. The team was organized by Birdability, a group that promotes accessibility in birding, and consisted of people with different disabilities. Despite challenging weather, the team persevered and won an award in the competition. Team member Jerry Berrier says that the team had to work together to find wheelchair accessible locations and quiet space for those with sensory concerns. And the group bonded quickly, like when Jerry volunteered to teach a teammate how to guide a person who is blind.

Ravens and Crows - Who's Who? Oct 16, 2022

Is that big black bird a crow or a raven? How can you tell? Ravens (seen right here) often travel in pairs, while crows (left) are seen in larger groups. Also, study the tail as the bird flies overhead. A crow's tail is shaped like a fan, while the raven's tail appears wedge-shaped or triangular. Another clue is to listen closely to the birds' calls. Crows give a cawing sound, but ravens produce a lower croaking sound.

Here Come the Merlins Oct 15, 2022

Smaller than a pigeon — but fierce enough to knock one from the air — are the powerful, compact falcons known as Merlins. Climate change is pushing ranges of many birds farther north, but more and more Merlins have been nesting farther south, in towns and cities across the northern United States. Merlins will take over old crow nests, especially in conifer trees, in parks, cemeteries, and neighborhoods.

The First North American Wildlife Refuge Oct 14, 2022

In the center of Oakland, California, is Lake Merritt. People row in it, picnic and jog around it, and it's a place of respite within the city. And it hosts waterbirds such as ducks, geese, egrets, pelicans, cormorants, and coots. A beautifully illustrated field guide by Alex Harris, The Birds of Lake Merritt, describes the birds found around the waters of Lake Merritt, its history since the Ohlone peoples have populated it, all the way till today.

Listening in on Birds Oct 13, 2022

Collecting data on wild birds is crucial for their conservation. But it requires huge amounts of effort. One way to help streamline the process is with gizmos called autonomous recording units, or ARUs. For days or months, these recording devices eavesdrop on the environment around them, including the songs and calls of the local birds. Identifying the songs picked up on recordings can be almost as time-consuming as in-person field work, but new AI tools are quickly making it easier to analyze the audio.

Ancient Murrelet Migration Oct 12, 2022

We're used to birds migrating north to south and south to north. But the Ancient Murrelet migrates east to west and back across the North Pacific. These plump seabirds nest in colonies in old-growth forests, in burrows and rock crevices. But where do they go in winter? After breeding, many Ancient Murrelets migrate westward. Around November, they end up in the Yellow Sea or the Sea of Japan. Two months after that, they head back, reaching British Columbia in March, and the cycle begins anew.

Ranching and Birding in Uruguay go Hand-in-Hand Oct 11, 2022

In the Departamento de Maldonado of Uruguay, lives a biologist, Nicolás Marchand, who has been working with ranchers to make conservation and sustainability compatible with raising cattle in grasslands. A kind of approach that makes sure pastures for livestock also help host birds like the Buff-breasted Sandpiper, which spend their winters here. He wants to keep enhancing connections with ranchers, restoring pastures, and creating management practices that benefit wintering shorebirds — all to avoid losing more of these crucial ecosystems.

Leave the Leaves Oct 10, 2022

To help backyard birds through the winter, do less. Leave the leaves or rake them under plantings. The tasty insects and spiders underneath will be food for the towhee and this Song Sparrow. Don’t deadhead. Pine Siskins and goldfinches love to snack on dead flowerheads. Make an insect hotel out of natural objects, flower pots, or other “found” items to create hidey holes for insects. They will become food for wrens and other birds.

Acorn Woodpecker Granaries Oct 09, 2022

The Acorn Woodpecker is found in parts of the western US. It chips small recesses out of trees to fit the acorns it will harvest throughout the fall. A family of Acorn Woodpeckers may use this storage tree, or granary, for generations. Some of them hold as many as 50,000 acorns. So does the Acorn Woodpecker just kick back and munch acorns all winter? Nope! In the weeks after a fresh acorn is lodged in a hole, it dries and shrinks. So Acorn Woodpeckers spend much of the winter shuttling acorns from one hole to another, finding just the right fit.

In the October sunlight, a Lincoln's Sparrow – like this one – sings energetically from a hedgerow. Soon a Fox Sparrow chimes in. Both nested in Alaska last summer but will spend the winter farther south. The Snow Geese are moving, too. A massive movement of birds takes place in the fall. The exodus of summer visitors to the tropics has given way to a surge from the north. And predators can't be far behind.

The call of the Common Loon brings to mind a summer visit to northern lakes. A "yodel" call is given by a male on his breeding territory. With his neck outstretched, the male waves his head from side to side, sending his eerie calls across forests and open water. The yodel entices females and asserts a claim of territory. Nothing common about this bird!

The Hardy Harlequin Oct 02, 2022

Some ducks don't sound like ducks at all. Some, like the Harlequin, squeak. Harlequins are unique in other ways, too. Quick and agile in rushing white water, they dive to the bottom of mountain streams for food, and use fast-flowing rivers for breeding. If you're lucky enough to spot a Harlequin Duck, you may guess how it got its name. Dressed in vivid multi-colored patches, Harlequin is the jester of traditional Italian comedy.

Green Heron Oct 01, 2022

The Green Heron forages on the banks of small bodies of fresh water. Relying on its plumage for camouflage, it perches motionless — body horizontal and stretched forward — waiting for small fish to come close. This heron may use "bait" while hunting for fish. It drops a feather, a live insect, or a twig on the water's surface. Then it hunkers down and waits for unsuspecting prey to venture within reach. Clever heron!

Seabirds in the Desert Sep 29, 2022

The White-vented Storm-Petrel is a small black and white seabird found off the coasts of Chile and Peru. Storm-petrels spend their entire lives at sea, except when nesting. Scientists had long been mystified about just where this species nests. A search lasting eight years led them to a site 50 miles inland in the Atacama desert, a place often compared to the surface of Mars. They employed dogs specially trained to sniff out seabirds. The dogs helped locate White-vented Storm-Petrel nests tucked into mineral deposits deep in the desert.

The Gulf of Fonseca is shared between El Salvador, Honduras, and Nicaragua. Ecologist Salvadora Morales studies best management practices in shrimp farming and salt production to benefit shorebirds in her native Nicaragua and other parts of the Gulf. The Wilson’s Plover, many of which breed in the southern U.S., comes to the shrimp farms of the Gulf to rest and refuel. But this is also a great place to have a shrimp farm. Salvadora and her team help make sure that the plovers are able to find places to rest within the shrimp farms.

Dippers on the Elwha Sep 25, 2022

In 2014, the dams on the Elwha River in Washington State were removed. As the river ran free again, salmon from the Pacific were able to spawn upstream for the first time in 100 years, dramatically improving conditions for American Dippers. Recent research has demonstrated that birds with access to salmon have higher survival rates. And they are 20 times more likely to attempt to raise two broods in a season, the most important contributor to population growth.

Bird in Flight, Strong but Light Sep 24, 2022

The feathers of a bird are, for their weight, among the strongest structures in the world. The bones of this Magnificent Frigatebird weigh less than its feathers! To further reduce weight while maintaining strength, many bird bones are fused. In addition, the pectoral and pelvic girdles and ribs are joined to make a rigid box that supports those long wings, just as the wings support the bird.

The Bird of Freedom Sep 23, 2022

There’s a bird in Cuba with plumage in blue, red and white — the same colors as the nation’s flag. The Tocororo, or Cuban Trogon, is the national bird of Cuba. When the Tocororo is kept in a cage, they often die. This fact has become a metaphor of freedom embraced by Cubans. The Cuban Trogon is a medium-sized bird often found in pairs. Its song sounds like its Spanish name, “Tocororo.” While el Tocororo is currently abundant, its population is declining due to loss of habitat.

Hear White-throated Sparrows Learning to Sing Sep 22, 2022

The White-throated Sparrow’s melancholy whistle is hauntingly beautiful. But when you hear an adult sparrow performing, just know that the bird wasn’t always an expert singer. In the fall, listen for White-throated Sparrows rehearsing their song. Inexperienced young birds sometimes begin with disorganized jumbles of notes known as sub-songs. As winter deepens, the first-year birds begin to get the syllables of their songs down, but they might sound shaky and off-key. But by summer, hopefully, all the new adult birds will be virtuosos.

The cheerful-voiced Chestnut-collared Longspur shares its northern prairie breeding range with grazing cattle. Although heavy grazing can have adverse effects, breeding densities of longspurs jump by two, three, or even 10 times when ranchers graze their cattle responsibly on native prairies. Two centuries ago, the birds were probably more abundant on prairies used by bison than on untouched stands of tall grass.

Why Are There Flightless Birds? Sep 17, 2022

The ability to fly seems to define birds. But there are more than 50 species of flightless birds throughout the world — from the Ostrich and Kiwi to flightless rails, ducks, and this Humboldt Penguin. Why did they evolve the inability to fly? Many dwelt on islands. Others evolved until they were huge -- like the extinct 12-foot-tall Moas of New Zealand. And the penguins? Unlike most flightless birds, they still have the strong flight muscles and keeled breastbones of flying birds. They are supremely graceful flyers. But they do it under water.

Putting the Hum in Hummingbird Sep 15, 2022

To figure out the source of a hummingbird’s hum, scientists built a special rig to measure air pressure, twelve high-speed cameras, and over 2000 microphones to observe hummingbirds fluttering in place at an artificial flower. The researchers found that the hum derives from the difference in air pressure between the top and bottom of the wings, which alternates forty times a second as the hummingbird flaps. The rapidly shifting air pressure produces a harmonic set of sounds, from low to high, creating that iconic, musical hum.

Connecticut Warblers nest in the northern boreal forests, migrate through the Midwest, and winter in the rainforests of South America. Even with all that traveling, you rarely see one of these birds. Though their loud, ringing song might be easy to identify, it often seems to emanate from low in a tree when the warbler is perched high in the crown, frustrating birders from Canada to Brazil.

Nuthatches Sweeping the Nest Sep 12, 2022

White-breasted Nuthatches aren’t the toughest birds on the block — but when it comes to their nests, they know how to put up defenses. Squirrels could easily duck inside a nest cavity and gobble up the eggs. That’s why you might see nuthatches sweeping around their nest hole with a beetle or other insect. It’s thought that chemical compounds from the insect smell bad to squirrels, driving them away. And if that doesn’t work, nuthatches try to make themselves look as big as possible.

All Those Fish in a Puffin's Beak Sep 11, 2022

Puffins fly under water into schools of slender fish, filling their large beaks. Fish are wedged into the gape, the stretchy skin at the beak hinge, but the bill edges still line up neatly. The dangling fish won’t slide out because the puffin’s tongue and roof of the mouth are heavily lined with backward-angled spines. When its beak is full, the adult flies back to its nest and feeds it all to a single chick.

Snail Kite - Bird of the Everglades Sep 10, 2022

When Florida became a state in 1845, the legislature declared the Everglades, America's largest wetland, totally worthless. In 1905, Napoleon Bonaparte Broward was elected governor on a campaign to drain them. So over the years, the slowly flowing "River of Grass" has been replaced by a series of reservoirs with little water movement. The endangered Snail Kite feeds only on the Apple Snail. And neither kites nor snails flourish in places that are permanently under water. Learn more at StateOfTheBirds.org.

Every spring in Northwest Ohio, the shores of Lake Erie transform into a birder’s paradise. Birder and author Kenn Kaufman, who lives in this area, says that of the many species that migrate through here, one group of vibrant, vivacious songbirds stands out from the rest: warblers. Trees leaf out later in the season along the lakeshore, making the tiny warblers easier to see as they forage for food. Northwest Ohio has earned a reputation as the Warbler Capital of the World among birders in the know. But Kenn wishes everyone could glimpse the beauty of warbler migration, even if they don’t make it to the Warbler Capital.

Catching Kori Bustards for Science Sep 08, 2022

In the animal world, large, charismatic species tend to get the most attention. But for the Kori Bustard, the largest flying bird in Africa, that attention hasn't translated to a ton of scientific research. Katherine Mertes, a research ecologist at the Smithsonian Conservation Biology Institute, tracks animals for a living, and a few years ago she was focused on Kori Bustards. Her team used solar-powered tracking devices to study the bustards’ movements. But first, they had to catch the birds — and trying to gently herd a bustard into a giant net is quite a task.

Birds Can Eat Toxic Berries Sep 07, 2022

Many bird species can eat the fruits of plants that are toxic to humans —even the white berries found on poison ivy. These birds just aren’t sensitive to the compounds in the berries that are irritating or poisonous to people. While you probably want to stay away from poison ivy, you can improve habitats for birds by planting native fruit bushes and advocating for wildlife-friendly gardening in public green spaces.

The Wilson’s Phalarope’s Dance Sep 06, 2022

Marcela Castellino works as a conservation specialist for Manomet’s Flyways team, visiting wetlands, salt lagoons, and salt flats around Mar Chiquita in Argentina, one of South America’s biggest salty wetlands. She surveys shorebirds to track their populations and strengthen their conservation. One species she studies, Wilson’s Phalarope, travels from their breeding grounds in North America to winter in huge numbers at Mar Chiquita. As they feed, they swim in circles, swirling the water and stirring up things to eat.

A Bird Migrates South, Step by Step Sep 05, 2022

Wood Thrushes migrate more than 2,000 miles each way, between their summer breeding territories in the US and Canada to where they winter in Central America. During migration, the birds will fly for hundreds of miles at night, then stop for days or weeks to refuel. In the spring, they’ll head north three times as fast as they did during their southbound fall migration.

The Fine Art of Dabbling Sep 04, 2022

Picture this Gadwall duckling swimming slowly across a pond, skimming the water’s surface with its broad, spatulate bill. This behavior is called dabbling. Along with the pond water, multitudes of tiny particles pass through the duck’s bill. Somehow it sorts out and swallows the edible seeds and invertebrates, while rejecting the tiny, inedible bits of grit, mud, and debris. To see how a duck pulls this off, we need to pry its bill open and look carefully inside.

Jaegers Give Chase in September Sep 03, 2022

A tern or gull plunges headfirst into the water, then bounces aloft grasping a small fish in its bill. But before the bird can swallow its catch, a Parasitic Jaeger swoops in. The jaeger nips the bird's wing, and it drops its hard-won fish. The pirate catches the fish in mid-air and gulps it down. The jaeger (German for hunter) is built for sprinting speed and predatory feats.

Bald Eagles Fledge Sep 02, 2022

When young Bald Eagles fledge, the event is the culmination of nearly a year’s work by the parents. Let’s recap how it might have gone: male and female build a nest over the winter. By March, they have two eggs. The female incubates the eggs for about a month, with the male taking an occasional turn. The result? A couple of tiny, three-ounce chicks. At eight weeks, they’re as heavy as the adults — 10 to 14 pounds. Two weeks later, they make their first flights. But it will take another 10 weeks of practice flights and provisioning by the adults before the young birds are ready to strike out on their own.

Banding Birds Sep 01, 2022

Willistown Conservation Trust in Pennsylvania carries out bird banding to help researchers understand bird populations. Led by licensed bird banders, a team of volunteers catches birds using mist nets — 8-foot tall nets made of fine nylon string that practically disappear when strung out between poles. After carefully untangling birds from the net, volunteers weigh and measure the birds, affixing a small metal band to their legs with a unique ID. Compiling records for many banded birds helps keep track of whole species.

Including Female Birds in Conservation Plans Aug 31, 2022

For many species of birds, scientists know more about the males than the females. And that’s a problem when making a conservation plan for a species that maps out which habitats to protect. Joanna Wu, a PhD student at UCLA, says that in some species of warblers, males and females live in completely different habitats during the winter. Joanna hopes to study how to better incorporate female birds into conservation efforts and ensure that the whole species is protected.

Male Mallards Disappear Aug 30, 2022

By late summer, the male Mallard’s need for fancy feathers to attract the females has passed. These birds have molted, and their bright feathers are replaced with mottled brown ones. Subdued colors help camouflage the male ducks, protecting them from predators. Come fall, the male Mallards will molt again and become the colorful dandies we remember.

Owls Migrate, Too Aug 29, 2022

When you think of bird migrations, you might think of a bluebird or a robin first. But some owls do migrate – such as the Short-eared Owl, which flies south for the winter. Northern Saw-whet Owls were once thought non-migratory, but in fact they travel at night, unseen. Snowy Owls breed in the Arctic then wander toward the south, staying wherever they can find food. Some Burrowing Owls spend their whole life in one place. But others migrate every spring and fall with the regularity of a bluebird.

Jays Identify Good Nuts by Shaking Them Aug 27, 2022

Some birds stash unopened seeds for use later. But how do they know which seeds are worth the trouble, before expending the energy to open them? A team of scientists from South Korea and Poland may have an answer. As part of a series of experiments, the scientists observed the behavior of Mexican Jays presented with peanuts in their shells. The research team documented the birds shaking nuts in their beaks to assess the weight and possibly listening for the nuts rattling. In other words, jays use the same types of sensory cues that humans do when choosing a melon in the supermarket.

Long, upward slopes called escarpments offer a good chance of seeing some of the many raptor species found in Belize. Shaped like a compact Red-tailed Hawk, White Hawks are white overall with black markings and scan the landscape for reptile prey. Bat Falcons have a darkly barred chest and cinnamon belly, and chase down swifts, dragonflies, and the bats that give them their name. Ornate Hawk-Eagles stand over two feet tall and are capable of catching monkeys.

August Molt Aug 25, 2022

By August, many birds have just completed the intense rigors of nesting and raising young and now undergo a complete molt. Molt is a cyclic process of feather growth. As new feathers grow in, they push the old ones out. Why molt? Because feathers wear out. Songbirds that migrate long distances need to complete this process on a tight schedule, to be ready when it's time to strike out in September. You might not even recognize this American Goldfinch in its winter plumage.

Protecting Petrels that Live on a Volcano Aug 23, 2022

The ‘Ua’u or Hawaiian Petrel is an endangered species once thought extinct or nearly so. But in recent decades, biologists have relocated some of their well-hidden nests — such as underneath the lava fields of Mauna Loa, an active volcano. Areas where the lava has long since cooled have deep tubes in which the ‘Ua’u can make their burrows. Despite their secretive burrows, the ‘Ua’u are still at risk of predators such as feral cats. A fence completed in 2016 keeps predators away from the petrel burrows, giving them a space to thrive.

What Osprey Chicks Reveal About Pollution Aug 23, 2022

Biologist Erick Greene has been taking blood samples from Osprey chicks in northwest Montana for years. Ospreys eat fish, so toxins in the water become concentrated in their bodies. Their blood offers a window into how pollution moves through the food chain. Finding high mercury levels in Osprey chicks helped Greene trace the toxin’s source.

Hear more about how Montana’s Ospreys are persisting despite pollution on the Threatened podcast.

Lights Out for Bird Migration Aug 22, 2022

Many birds migrate at night, taking advantage of less turbulent conditions and cooler temperatures. But that also means that migrating birds can get disoriented by bright lights and collide with a building. Julia Wang is the project leader for BirdCast, which provides forecasts for bird migration so that people know when they should keep their lights off. Turning off the lights during peak migration times can save birds and save energy at the same time.

Building Chimney Swifts a New Home Aug 19, 2022

Public radio station WYSO in Yellow Springs, Ohio, renovated a historic schoolhouse to move into. But there was a bird problem: the old chimney had to come down, and Chimney Swifts were known to nest in it. So the station decided to custom-build the swifts a new home: a Chimney Swift tower right on the front lawn. The builders worked quickly to finish the tower ahead of the Chimney Swift’s spring migration, and WYSO staff members played recordings of swift calls to help attract them to the new home.

Raising the Clever ‘Alalā Aug 18, 2022

The ‘Alalā is a crow species that only lives on Hawai’i. In the 1990s, the species was on the verge of extinction. So biologists decided to raise ‘Alalā in captivity, aiming to release them once the captive population was big enough. But these intelligent birds have to learn many skills to survive in the wild, such as communication skills and avoiding predators. Several ‘Alalā were released and seemed to get the hang of avoiding hawks. These experienced birds returned to captivity and could help pass on their knowledge to the next generation.

How Birds Stay Cool Aug 17, 2022

On a hot summer’s day, watch a bird such as a crow — or this Purple Martin — very carefully. You’ll never see them sweat, because birds don’t have sweat glands. So how do they keep cool? One way is panting. As the bird breathes rapidly, heat is carried out of its body through the lungs and air sacs. Bare skin on the legs, face, and beak also help with cooling. So do puffing out feathers, fluttering wings, or splashing in a puddle or birdbath. And soaring birds like hawks can simply ride the updrafts far above ground to cooler air.

Saving Honeycreepers from Avian Malaria Aug 16, 2022

Avian malaria has devastated native Hawaiian birds called honeycreepers. And now, climate change is allowing the mosquitoes that carry the disease to spread into the last mountain refuges of highly endangered honeycreepers on the island of Kauai. However, there’s hope that a new tool could eradicate the disease. Researchers are raising mosquitoes in the lab infected with Wolbachia, a bacterium that makes them infertile. When these males mate with wild female mosquitos, they fail to reproduce. While they wait for the mosquito solution to become available, biologists are carrying out last-ditch efforts to keep the species alive in captivity.

The Women Who Fought the Feather Fad Aug 15, 2022

In the late 19th and early 20th centuries, the human fascination with bird feathers went a little too far. Women’s hats and dresses featured extravagant feathers from birds both near and far. The trade in feathers drove several species, from the Little Egret to the Great Crested Grebe, to near-extinction. Fed up with the killing of wild birds for fashion, a group of British women met to put an end to this cruelty. The organization became the Royal Society for the Protection of Birds, or RSPB, which continues to be a leader in bird conservation today.

The Phoebe and the Pewee Aug 14, 2022

The Eastern Phoebe (pictured here) is one of the most familiar flycatchers east of the Rockies. Because the Eastern Phoebe repeats its name when it sings, it’s a pretty straightforward voice to identify and remember. But there’s another flycatcher east of the Rockies that whistles its name over and over: It’s the Eastern Wood-Pewee. This bird is more often heard than seen. And it wouldn’t be unusual to hear a pewee and a phoebe at the same spot. With careful listening, though, you can tell them apart by their singing styles.

Hawai‘i’s One-of-a-Kind Bird Diversity Aug 11, 2022

Hawai‘i is home to many birds found nowhere else. In a stunning example of natural selection, birds called honeycreepers evolved to fill many different roles in Hawaiian ecosystems. Tragically, many native Hawaiian birds have gone extinct, including over half of the honeycreepers. The threats they face include habitat loss, disease, and introduced mammal species that prey on them. But some honeycreepers, such as a bird called the Palila, hang on to survival. Efforts to protect the Palila from invasive species could help the birds thrive again.

Humboldt Penguins living along the Pacific Coast of Chile and Peru are adapted to cold. But on land, temperatures rise to 100+ degrees, and penguins need to cool off. So these penguins have pink patches of bare skin on their face, under their wings, and on their feet. On hot days, the patches turn a deep, rosy color, as blood rushes to the surface to dissipate heat. They appear to be blushing, but they’re really flushing!

How High Birds Fly II Aug 07, 2022

Bar-headed Geese, champions of high-altitude migration, leave their nesting grounds in Tibet and scale the Himalayan range on their way to wintering grounds in the lowlands of India. How do they do it? These geese have a breathing structure that extracts oxygen from thin air, even at 30,000 feet. Inhaled air passes through the lungs and is temporarily stored in several sacs, then circulated back through the lungs. The capillaries in their breast muscles are more numerous than in other birds, providing the muscles with a greater supply of oxygen.

What Do Desert Birds Drink? Aug 06, 2022

In the desert Southwest, water can be scarce. Yet some birds, like this Black-throated Sparrow, thrive in a scorching landscape. The birds obtain moisture from foods like nectar and fruit, as well as insects and other prey. They tuck into the shade in the heat of the day, so they won’t lose water in panting. And they have extremely efficient kidneys, so they excrete almost no liquid. Amazing!

Truffle-Hunting Birds Aug 05, 2022

With their excellent sense of smell, pigs are renowned for sniffing out truffles, a fungus that grows underground and is prized for its taste. But it turns out that some bird species can also find their way to a truffle treat. Researchers working in the Patagonia region of Chile had noticed truffles with little beak-sized bite marks, and even watched a bird eat a truffle. They found truffle DNA in the birds’ droppings, suggesting that truffles are a staple of the birds’ diet. Some of the fungi species eaten by the Patagonian birds look like berries that grow locally, which might help birds see them better.

New Zealand Ranger Saving Birds from Stoats Aug 04, 2022

Ranger Evan Smith of New Zealand’s Fiordland National Park is, according to one visitor, “a bit of a legend.” Since 2011, Ranger Smith has raised money to help protect native birds from stoats, a kind of weasel introduced from Europe. When he began working on the Routeburn Track hiking trail 20 years ago, he didn’t see or hear many birds. His nightly “hut talks” has helped the project raise $200,000 for stoat control. And summer by summer, the park sees more bird life along the trails.

The Pungent Mudflat Aug 03, 2022

On the shore of a saltwater bay, the tide goes out, revealing a broad expanse of dark, glistening mudflat. Mudflats are rich in nutrients, such as decomposing organic matter and minerals. Far from wastelands, mudflats also support a bounty of life including vast quantities of tiny snails and clams, worms, crustaceans, larvae, and much more. Millions of shorebirds - including these Lesser (right) and Greater (left) Yellowlegs - follow shorelines and their mudflats each spring and fall, where they feast upon those tiny creatures hidden beneath the mud's surface, a banquet that powers the birds' continent-spanning migrations.

Burrowing Owls Hiss Like a Rattlesnake! Jul 31, 2022

Despite its name, the Burrowing Owl doesn’t do much digging. It’s better known for its hair-raising hiss, which may have evolved to mimic the warning of a cornered rattlesnake. The sonic threat of a venomous reptile could be just enough to warn away most unwanted visitors from the owl’s nest burrow. In one experiment, ground squirrels were nearly as alarmed by the Burrowing Owl’s hiss as they were by the recording of a real rattlesnake!

Birds called prions have an especially creative approach to getting their food. They pass seawater through their mouths and filter it to catch tiny animals such as krill and other small crustaceans. It’s similar to how baleen whales feed, leading to the prion’s nickname: the whale-bird. The sides of their bills have comb-like structures. Small food items get trapped in the combs as water flows past. In Greek, the word “prion” means saw, which refers to the bird’s highly specialized mouth.

Are Birds Nests Reused? Jul 27, 2022

Let’s talk about nests. Every spring, robins build their cup-shaped nests using grass and mud. Orioles weave a hanging sack. It’s hard work, and yet once the chicks fledge, the structures probably won’t be reused. But bigger birds, such as herons, hawks, and eagles, often reuse a nest for many years. Europe’s migratory White Storks — like those pictured here — get the award for best reuse. One nest site, still used in 1930 and likely seeing many repairs, dated back to 1549. That’s a continuous series of stork pairs nesting in one spot for 381 years!

Making Birding Spots More Accessible Jul 26, 2022

Freya McGregor is the coordinator of Birdability, an organization that works to make birding more accessible and inclusive for people with disabilities. She says that one of the big challenges is that different parts of accessible design don’t get connected — for example, when a paved trail for wheelchair users has info signs placed too from the trail to read. Designing parks with accessibility in mind from the parking lot and all along the trail can help make outdoor experiences for people with disabilities more self-directed and independent. Learn more about Birdability on the Bring Birds Back podcast.

BirdNoir: The One That Got Away Jul 25, 2022

In this episode, the Private Eye tells his saddest story: his nemesis bird. That’s what birders call a species that keeps giving you the slip. His nemesis is the Painted Bunting, a colorful gem of a bird. When word of the species being spotted nearby reaches the PI, he rushes off to see it, hoping to end his struggle to see the bird at last…

Playful Keas Jul 24, 2022

Keas are large alpine parrots from New Zealand. Intelligent and social, they have olive-green plumage, a red rump, and a long, curved beak. Keas produce a distinct warbling call, a “play call,” that sounds — and functions — much like a human’s contagious laughter. Scientists made recordings of captive Keas making warbling calls, then played them for wild Keas. They began playing harder and even engaged birds that hadn’t been playing. Hearing it seemed to put them in a playful mood, even when they were alone.

Swift Bricks Jul 23, 2022

Common Swifts in Europe nest in eaves and under roof tiles and gables. But modern construction doesn’t have these nooks and crannies, and populations of swifts have been declining. However, there’s a solution called the “swift brick,” a small nesting box that fits right into the wall of a house or office building.

Bird Scent: It's All About the Bacteria Jul 22, 2022

Many birds have an excellent sense of smell. And the odors that birds make can act as mating signals for some species. The source for many of these scents, says biologist Danielle Whittaker, are the microbes that live in birds’ preen oil, which they use to keep their feathers in good condition. Danielle and other scientists are studying how the genes that regulate birds' immune systems might help control these microbes. This research could help connect the birds’ genetics to the scents they use to attract mates. Learn more in Danielle Whittaker’s new book, The Secret Perfume of Birds: Uncovering the Science of Avian Scent.

Does a Robin Hear Its Worm? Jul 21, 2022

How does a robin know a worm is in one exact spot? Does it see the worm or hear it? Smell it? Sense its movements through its feet? To find the answer, researchers buried worms in soil in a tray. They covered the soil with a thin but opaque sheet of cardboard, followed by more soil, so the robin couldn’t see the worms. Still, the robin found them with ease. The scientists concluded the birds are listening for their prey. There’s always more to learn about birds!

Island Scrub-Jay Jul 20, 2022

Only the most intrepid birders lay eyes on the striking cobalt feathers of the Island Scrub-Jay. They live exclusively on Santa Cruz Island, which is part of California’s Channel Islands National Park. The species has the smallest range of any bird in North America. The jays have few natural predators or competitors for food, letting them grow larger than their continental counterparts. But the birds’ isolation makes them susceptible to diseases such as West Nile Virus. Scientists are considering a vaccination program and possibly relocating some jays to nearby Santa Rosa Island.

Helpers at the Nest Jul 19, 2022

Brown Jays, like this juvenile, make nesting a family affair. The entire flock takes care of a single nest, which holds four eggs laid by one female in the flock. Each bird brings food to the young. And when the young first leave the nest, the helpers teach them to find food and recognize danger, skills necessary for survival into adulthood. In turn, the helpers may inherit the nesting territory when they come of age.

Recreating a Princess’s Feather Skirt Jul 18, 2022

Rick San Nicolas is a master featherworker, carrying on a tradition of making elaborate feather garments that dates back centuries in Hawai’i. He’s recreating the famous pā‘ū, or skirt, given to Hawaii’s Princess Nāhiʻenaʻena nearly 200 years ago on Maui. The original pā‘ū was made mostly from the feathers of a bird called the ʻōʻō. Now, all ʻōʻō species are extinct, due to the effects of invasive species and habitat loss. That makes the original pā'ū a remarkable sign that ʻōʻō’s were once present on Maui.

Most Kingfishers Don't Fish Jul 17, 2022

In North America, kingfishers fish. But in tropical regions of Asia, Africa, and Australia, most of the roughly 90 species of kingfishers don’t “fish.” They hunt in woodlands, where the smaller ones, like the four-inch Pygmy Kingfisher, eat grasshoppers and centipedes. Larger kingfishers will take frogs, reptiles, small mammals, and even snakes. This Pied Kingfisher, found in Africa and Asia, does eat fish.

Did you know that Australia’s Laughing Kookaburra is a member of the kingfisher family? It has been known to dispatch snakes up to three feet in length.

Night Voices of Summer Jul 16, 2022

At the close of a summer day, the songbirds go silent. As if on cue, the birds of the night make their voices known. In an Eastern woodland, the eerie trills and whinnies of an Eastern Screech-Owl are among the first sounds of the night. Meanwhile, as night falls west of the Rockies, a Western Screech-Owl (like this one) calls out. But there’s another bird whose voice will drown out the loudest of screech-owls: the Barred Owl! Pairs may break into a rollicking duet, sometimes called their “monkey call.”

Woodpeckers and Forest Fires Jul 15, 2022

A forest fire roars along a mountain slope once green with spruce and pines, ignited by a lightning strike late in a Northwest summer. Once the fire has run its course, acres of blackened trunks stand silently against the blue sky. But by next summer, woodpeckers have discovered the charred forest and the feast of insects it provides. The Black-backed Woodpecker - like this female - comes closest to being a burnt-forest specialist. It will even form loose nesting colonies in recent burns.

The Arctic Report Card Jul 14, 2022

Many shorebirds breed in the Arctic tundra. It’s such an important ecosystem that every year, the National Oceanic and Atmospheric Administration issues an Arctic Report Card that details how the region has been affected by rising global temperatures. Over the last ten years, satellite data has shown that shrubs are spreading in the north. Shorebirds that nest among low-lying tundra plants may soon find woody thickets encroaching on their breeding grounds, which could have ripple effects on shorebird populations around the world.

Glowing Feathers Jul 12, 2022

When a Northern Saw-whet Owl spreads its wings, many birds can see something our human eyes can’t: the owl’s flight feathers glow with ultraviolet light. It’s invisible to humans without the help of a UV blacklight. While the glowing feathers on parrots might help them attract mates, the reason for the owls’ glowing feathers still isn’t clear. However, scientists realized that they could estimate an owl’s age based on the pattern of luminescent color on the wings, which changes predictably as birds grow and replace their feathers.

Do Birds Use Ants as Tools? Jul 11, 2022

The purpose of anting remains something of a mystery, although most experts agree it has to do with transferring the ants’ secretions to the bird’s body. It’s likely that the ants’ formic acid helps the bird control feather-mites and other parasites.

Anhingas - Snakebirds Jul 10, 2022

In the black water of a Louisiana bayou, the water ripples where a slender form glides just beneath the surface. It appears to be a snake, but look closer at the long, narrow spike of a beak. It’s a Snakebird, a colloquial name for the Anhinga, swimming with just its head and neck above the water. An Anhinga hangs motionless in the water or swims slowly just below the surface, its neck crooked, like that of a cobra. When an unwary fish swims close, the bird’s head darts forward, impaling its prey. Then it flings it in the air and downs it headfirst!

Birds as Pollinators Jul 09, 2022

Birds are part of the complex web of Nature, and each fits into this web in its own way. Some even pollinate flowers! While feeding at a flower, this Rainbow Lorikeet gets pollen on its forehead and throat. When it visits another flower of the same species, it transfers the pollen to that flower. The pollen fertilizes the plant's eggs to produce its seeds, and the plant's reproduction is assured.

A Tiny Island Full of Terns Jul 08, 2022

The Northeast population of Roseate Terns is endangered. Each summer, roughly twenty-five hundred Roseate Terns are found on Ram Island, a 2.5-acre island off the coast of Massachusetts. In the 1960s and 70s, gull numbers surged. Gulls drove terns off of Ram Island, until biologists began chasing off the gulls to encourage terns to nest there again. Their efforts were successful: today, about one in five Roseate Terns in North America nests on the island. The site is designated as an Important Bird Area (IBA.)

Baby Bald Eagles Jul 07, 2022

A recently fledged Bald Eagle, a juvenile just learning to fly, lands unceremoniously on the ground. The parent Bald Eagles may react by calling from a tree, or they may have to descend to the ground themselves, to tend to and encourage the young bird to take flight again. Young Bald Eagles do not reach full adult plumage until they are around four years old and may live up to 40 years.

Slowing Down and Observing Female Birds Jul 06, 2022

The colorful feathers and loud songs of male songbirds often catch a birder’s attention first. Observing females often means birding more slowly, noticing subtle differences in plumage and behavior, says Joanna Wu, who’s part of a group called the Galbatrosses that’s encouraging birders to spend more time identifying female birds. Fellow Galbatross Purbita Saha says that watching for females can help us understand birds on a deeper level by observing them as individuals rather than just species.

Life on the Beach with Wilson's Plovers Jul 05, 2022

Along the Gulf of Mexico, you’ll find undeveloped sandy flats and shallow lagoons. This is prime habitat for Wilson’s Plovers to nest and raise their chicks. But life on the beach can be tough for birds. In many parts of its U.S. range on the Gulf and south Atlantic coasts, Wilson’s Plover habitat is at risk. One practice that has helped these beach birds is to place low, temporary fencing around key nesting areas.

Being an Ethical Birder Jul 04, 2022

Birding has many benefits for your well-being. But Martha Harbison, the vice president of the Feminist Bird Club, says you should make sure your relationship with birds isn’t just about taking, but about giving back, too. You’re benefiting from the birds and the places they live, so you should do your part to care for those birds. And make sure to keep other birders in mind, too. You can hear more about how to be an ethical birder on the Bring Birds Back podcast.

Summer Tanagers: Wasp Hunters Jul 03, 2022

Summer Tanagers snatch bees and wasps in mid-air, as they buzz about. Bug in beak, the bird flies to a perch, slams the insect against a branch until it’s dead, then wipes it against the branch to remove the stinger before eating it. Summer Tanagers will also tear open paper-like wasp nests to dine on the larvae within. The migratory birds will also eat other insects and spiders, as well as fruits and berries in the summer and over the winter.

Where Birds Sleep Jul 02, 2022

All birds need to sleep — or at least snooze — sometime during each 24-hour period. And most sleep at night. A bird (such as these Mallard Ducklings) may turn its head around and warm its beak under its shoulder-feathers. Songbirds find a protected perch, sheltered from rain and nighttime predators. Small forest birds often spend the night in tree cavities. Ducks sleep while floating in protected bays.

Cowbird Mafia Jun 29, 2022

Brown-headed Cowbirds have a sneaky approach to parenthood. They lay eggs in the nests of other songbirds, and the songbird hosts often raise the cowbird chick as their own. It’s called nest parasitism. But sometimes the hosts throw out the odd-looking egg. And when that happens, the cowbirds sometimes retaliate by destroying the hosts’ other eggs. Scientists call this “mafia behavior,” likening it to organized crime groups enforcing their demands on unwilling business partners.

Flyin' in the Rain Jun 28, 2022

Most birds are mostly waterproof. Their feathers, aided by oil from preen glands, keep them pretty watertight. So why do birds avoid flying during rainstorms? It may have more to do with the air than with the water. Rainstorms tend to occur when atmospheric pressure is low. Air in a low-pressure system is less dense. But it’s dense air that gives birds the aerodynamic lift they need to take wing. Falling rain and high humidity make air even less dense. Many birds perch and wait out a storm. Afterward, birds once again take to the skies.

The massive Kori Bustard struts across the savannahs of Eastern and Southern Africa. Its crested head sits on top of a long neck and stilted legs. And this winged giant has a colorful companion. A small bird called the Carmine Bee-eater perches on the bustard’s back. The Kori Bustard and the Carmine Bee-eater have a symbiotic relationship where at least one of them benefits. While the bustard searches for lizards, rodents, and other prey, it kicks up smaller insects that the bee-eater snatches up.

Spider Silk - Duct Tape for Bird Nests Jun 25, 2022

The spider’s web is an intricate piece of precision engineering. Made from large proteins, it’s sticky, stretchy, and tough. So it’s no surprise that many small birds — including this Anna’s Hummingbird — make a point of collecting strands of spider silk to use in nest construction. Spider silk not only acts as a glue, holding the nest together, but it’s flexible enough to accommodate the growing bodies of nestlings. And it’s resilient enough to withstand the bustle of raising those hungry babies.

Reckoning with Audubon's Legacy Jun 24, 2022

John J. Audubon’s name is featured in the titles of many bird conservation groups. The Audubon Naturalist Society, or ANS, is one of the oldest, though not the largest, which is the National Audubon Society. In 2021, ANS, that smaller organization based near D.C., announced that they're retiring the Audubon name, given that Audubon enslaved people and held racist, white supremacist views about Black and Indigenous people. Caroline Brewer, who was integral to this decision, says that name changes like this are an opportunity to accept responsibility for the future and build an environmental movement that includes all people.

Seasonal Flooding of the Amazon Jun 22, 2022

When it’s predictable and wildlife is well adapted, natural flooding can create a biological bonanza. In the Amazon River Basin, which holds one-fifth of the world’s fresh water, annual rains can raise water levels 30 to 40 feet in just days. Forests turn into vast lakes, dotted with trees, while a massive push of sediment erects new islands almost overnight. It’s a lush world that’s home to some of the world’s most iconic birds, including toucans, macaws, kingfishers, tiger-herons, and this Russet-backed Oropendola.

The Dickcissel Jun 21, 2022

In grasslands of the central U.S., birds called Dickcissels sing a quirky song that “spells out” the syllables of their name. Dickcissels are approachable birds, often chirping away while a person walks nearby. But they’re also masters of concealment, hiding their nests from predators in tufts of grass and leafy wildflowers. Dickcissel populations have fallen by 30 percent since the 1960s. Yet the birds persist in searching for places to breed — nesting along roadsides, in pastures, and even in alfalfa fields.

Can Crows Laugh at Me? Jun 20, 2022

The American Crow’s rattle call is uncommon, and researchers aren’t sure what it means. It could be a gathering call, a predator alarm, or a call between mates. But if you hear it, you might think it sounds like cackling laughter. However, no one has identified a crow noise that indicates glee at the expense of another creature. It’s just a coincidence that the rattle sounds like a laugh. However, crows can play pranks on other animals: egging on cats to fight and yanking on dog tails for their own amusement. They aren’t pranking for survival — as far as we can tell, it’s just for fun.

Which Species of Bird Sings First in the Morning? Jun 18, 2022

The dawn chorus is that time when, just before sunrise, birds begin to sing. One by one, then all together, their voices join to greet the new day. But which bird sings first? The timing of when a bird joins the chorus seems to depend on how well it can see in low light. So the birds with bigger eyes -- like a Gartered Trogon -- start to sing first.

Having Your Tail Scared Off Jun 17, 2022

When a hawk is about to capture a songbird, the songbird has one last trick: a fright molt. It’s when a bird loses feathers due to sudden stress. This usually involves feathers near the tail or rump, where they’re most likely to be attacked as they flee. It can be a saving grace when the bird is about to be caught — similar to a lizard dropping its tail. There’s a downside to having your tail scared off. A tail helps the bird turn and balance in flight. But if dropping feathers lets the bird live to chirp another day, it’s worth it.

Precision Flight in Flocks: How Does It Work? Jun 16, 2022

A flock of shorebirds flying wingtip to wingtip seems to act like a single organism, rolling and twisting in exquisite patterns. Flocks like these use a combination of two organizational patterns. One is a “cluster”: lots of birds flying together in a loose, three-dimensional cloud. The second is a basic V-formation, where smaller groups of birds within the flock sync up in V-shapes, like migrating geese. Voilà! Predator avoidance and aerodynamic efficiency.

How to Be a Better Wildlife Photographer Jun 15, 2022

Conservation photographer Noppadol Paothong says that if you go out to take pictures of birds, you shouldn’t just aim to take an eye-catching photo. He spends long hours in photo blinds, often watching and studying birds rather than photographing them. He has become deeply familiar with some populations of sage-grouse, to the point that he can recognize individuals. Caring about the wildlife you photograph, particularly for rare and declining species, will make you a better photographer, he says. Noppadol strives to highlight the challenges that birds face through his photos and point toward solutions.

Kestrels Love Nest Boxes Jun 14, 2022

This American Kestrel evolved to nest in tree cavities or small caves in cliffs. We humans have made life difficult for kestrels. Development has shrunk the open spaces they need. We’ve cleared away dead trees they rely on for nests and sprayed pesticides that eliminate the insects the birds eat. But we humans are also in a position to help. Volunteers are helping to build and put up nest boxes, improve habitat, and monitor these cool little falcons. Together, we can #BringBirdsBack.

Komodo Dragons and Cockatoos Jun 13, 2022

Due to trapping for the pet trade, the talkative and showy Yellow-crested Cockatoo is now considered critically endangered. But scientists recently discovered a stronghold for the species: Komodo Island — yes, the one with the dragons. The Komodo population of Yellow-crested Cockatoos appears stable. The island has been an Indonesian national park since 1980. Park rangers may have helped deter poachers, but community support for conservation and the literal dragons have played a role, too.

Turkey Vulture - Sky Sailor Jun 12, 2022

Although some of the Turkey Vulture's habits may evoke our disgust, these remarkable birds also inspire our awe. With wingspans approaching six feet, Turkey Vultures ride currents of air to make their spring and fall journeys, and to cover the miles of their home range in summer. Gliding on updrafts, or pushed along by weather fronts, Turkey Vultures rarely need to flap their wings more than ten times in a row. To rise above storms, they ride upward on thermals.

Fairy-Wrens Sing Secret Passwords to Unborn Chicks Jun 11, 2022

Superb Fairy-wrens teach their embryonic chicks a secret code. This "incubation call" contains a special note that will later serve as a password. When the chicks have hatched, this password enables the adult birds to identify their babies in the darkness of their domed nest. A species of Australian cuckoo lays its eggs in the wren’s nest, hoping to pawn off the task of parenting. But wren chicks learn their mother’s song and incorporate the password note into their begging calls.

Spark Bird: Meghadeepa Maity Jun 10, 2022

Meghadeepa Maity grew up in India on the outskirts of a city that still had pockets of green space here and there, like their family’s garden. They started noticing one bird species in particular that flocked to the garden. With their sister, Meghadeepa searched the web and learned the birds were called Oriental Magpie-Robins. This species helped awaken Meghadeepa to the wider world of birds. Now birding in Massachusetts, they’ve helped create a project called The Murmuration that crowd-sources info about how to access birding spots. Contributors can share how safe they felt in a place so that other people know what to expect.

Tenijah’s Birding Journey Continues Jun 08, 2022

Tenijah Hamilton, the host of the Bring Birds Back podcast, has learned a lot since she started birding at the start of the pandemic. She visited a park to show her mom how much she has grown. At first, the birds were sparse. Overcoming her frustration, Tenijah felt like nature was reminding her of lesson number one: birding is supposed to be fun. And soon their luck changed with a Northern Mockingbird flying by. What’s more, Tenijah realized that a birding trip isn’t a waste if you’re with your people. Hear more about Tenijah’s birding journey on Bring Birds Back.

Have You Ever Seen a Pink Gull? Jun 07, 2022

Some gulls and terns may show a glowing pink color, similar to that of flamingos and spoonbills. This pink color comes from pigments in the birds' food called carotenoids. These gulls and terns are able to convert these naturally occurring pigments to hues that may enhance their success at attracting a mate.

Scarlet Tanagers Under the Canopy Jun 05, 2022

In summer, the forests of the eastern United States are home to a bounty of birds, including this gorgeous Scarlet Tanager, which spends most of the year in tropical South America. The male’s body is a dazzling red, in contrast to his black wings and tail. It seems that these boldly colored birds might offer an easy target for a birdwatcher’s watchful gaze, but male Scarlet Tanagers can be hard to spot!

Bonding with Mom Through Birding Jun 04, 2022

In this episode, environmental educator and nature enthusiast Nicole Jackson tells the story of an unexpected backyard birding experience when she visited her mom in 2021. When she arrived, Nicole saw typical birds such as robins and jays, but then saw something less common: a brightly colored Blackburnian Warbler! Nicole’s mom asked what she was looking at, and Nicole showed her pictures of all the nearby birds on her phone. Nicole helped her mom create an account on Merlin Bird ID and document her first bird sighting.

Bringing Birding Adventures to Broward County Jun 03, 2022

While Sierra Taliaferro was working as a Naturalists in Broward County, Florida, in 2021, she collaborated with Broward County Library to help enhance the public’s knowledge about birding. More people became interested in birding as a safe outdoor activity during the pandemic. Sierra and others designed birding backpacks with field guides and binoculars that could be checked out at 10 libraries throughout the county. Sierra also gave a webinar crash course on how to find birds. The program was a success, with many people checking out the backpacks and creating their own birding adventures.

Dinosaurs in the Here and Now Jun 02, 2022

In this episode, Adé Ben-Salahuddin, an evolutionary biologist in training, reflects on how his connection with birds has changed over the years. The simple fact that birds are the only living dinosaurs left was what drew him to birds for a long time. He would share that fact with visitors on guided tours of the fossil collections at his local museum. During COVID, the museum closed for renovation, so Adé began working at a warehouse instead, surrounded by the sounds of whirring machines and beeping scanners. More recently, he has been visiting a local pond that hosts many species of birds and has developed an appreciation for them as living dinosaurs.

Urban Birding with Deja Perkins Jun 01, 2022

In this episode, urban ecologist Deja Perkins talks about how many bird species live right within bustling cities. Whether you’re on your porch, at your local park, or the parking lot of your favorite store, you can find birds. Deja suggests taking five minutes to focus your attention on birds. Look up in the sky, along power lines and the tops of buildings. Close your eyes and listen — past the sounds of traffic — for the songs of nearby birds.

Sheridan Alford on Birding and Mental Health May 31, 2022

Sheridan Alford helps organize Black Birders Week, which celebrates Black people who love birds with a week of interactive events. She’s passionate about the mental health benefits of birding, especially for people who have experienced trauma. Sheridan says that sitting and journaling about what you observe can help you feel grounded. Becoming aware of the birds living around you can help you tap into their resilience in a changing world. Learn how to participate in Black Birders Week here.

Spark Bird: Dara Wilson and the Blue-gray Tanager May 30, 2022

While Dara Wilson was working at the Smithsonian’s National Zoo in D.C., she introduced visitors to the Amazonia exhibit. She would describe the song of a bird she’d never had the chance to see in the wild, the Blue-gray Tanager. But when Dara moved to Panama, she heard the song that she knew by heart already. Encountering the Blue-gray Tanager in its natural habitat inspired her to keep learning about birds — and to share that knowledge with others as an educator. Dara helps organize Black Birders Week. Find out how you can participate here.

The Black Heron May 29, 2022

The canopy feeding method used by the Black Heron, also known as the Black Egret, is an impressive trick. It spreads its wings out like it's mimicking an umbrella and waits. Unsuspecting fish think this is shade from vegetation and a safe place to hide — and that is when the bird strikes! This pitch-black heron creates canopies in shallow open waters and seasonally flooded grasslands through Sub-Saharan Africa and Madagascar. Culturally, herons are seen as sacred messengers and symbols of prosperity and good fortune. The Black Heron is the bird chosen to represent this year’s Black Birders Week, which begins today. Learn how to participate in this year’s events here.

Celebrating Female Bird Day May 28, 2022

In 2019, several co-workers at the National Audubon Society formed a team for the World Series of Birding that focused on identifying female birds. Called the Galbatrosses, they sought to highlight how female birds have been understudied and unfairly written off as quieter and less interesting. Since then, the Galbatrosses have led events about IDing female birds and held the first Female Bird Day over Memorial Day weekend in 2020. Learn more at BirdNote.org.

Limpkin - Bird of the Swamp May 27, 2022

It's dawn on a spring day in the Big Cypress Swamp of Florida. Mist rises from quiet water into Spanish moss hanging from the cypress branches. A Limpkin is foraging for apple snails. When it touches a big, round shell, it grabs it quickly and pulls it from the water. Then, moving to solid ground, the Limpkin positions the shell, and using the curved tip of its lower mandible, it scissors loose the operculum and pulls out the snail. Learn more at BirdNote.org.

Ospreys and Baling Twine May 26, 2022

Each year, two Ospreys known as Charlie and Charlotte nest near the Owl Research Institute in Montana. A webcam of their nest gives people an intimate glimpse into their lives. In 2021, Charlie brought some baling twine into their nest. Baling twine is a plastic string used to bind hay and straw. When brought into a nest, chicks can get fatally tangled — including as many as 10% of Osprey chicks. Fortunately, there are organizations working to protect Osprey chicks from baling twine. Learn more at BirdNote.org.

Night Voices - Nightjars May 25, 2022

As darkness descends on a May evening, the voices of many birds go quiet. But for some birds, especially those known as nightjars, the music is just beginning! An Eastern Whip-poor-will shouts out its name. The call of a Common Poorwill echoes across a canyon. A Common Pauraque calls from the thorn scrub. A Buff-collared Nightjar repeats its Spanish nickname, Tucuchillo. And a Chuck-will’s-widow like this one calls from a woodland. Learn more at BirdNote.org.

Songbirds Teach Each Other Tricks May 24, 2022

In the UK for years, milk came in bottles with foil caps. Great Tits, a common songbird, learned how to peck through the foil. The skill spread. But how? Researchers trained Great Tits in different ways of opening a box and re-released them. Knowledge of how to open the box spread rapidly, with most birds copying the trained bird in their group. In a follow-up study, the researchers made one method of opening the box more effective. Many birds quickly switched to the better method, suggesting the tits can stand up to peer pressure if they see there’s a better way of doing things. Learn more at BirdNote.org.

Singing Sandpipers May 23, 2022

We've all seen sandpipers foraging busily on mudflats or at the ocean's edge. But this Lesser Yellowlegs often carols from the top of a tall conifer in its nesting territory in Alaska. The name "sandpiper" actually comes from the voices of these birds, rather than from their long-billed probing in the sand. While the name refers in particular to the birds' short "piped" -- or whistled -- calls, a number of sandpipers are surprisingly good singers. Learn more at BirdNote.org.

Saving Snags for Red-headed Woodpeckers May 22, 2022

Red-headed Woodpeckers excavate cavities in large, dead trees called snags. Yet, over much of the Red-head's range, snags are frequently cut down as unsightly, or because they make good firewood. There are ways we can help the Red-headed Woodpecker -- and many other woodpeckers, too. The key is to leave snags intact. If you must cut down a tree on your property, consider leaving the lower trunk as a snag - a veritable condominium for wildlife!

In the meantime, consider creating a nestbox for a woodpecker. Learn more at BirdNote.org.

Bird Sound Types and Qualities Part III May 21, 2022

When it's just too hard to see the bird you hear, let your ears take over! Listen for the qualities of the sound as well as the pattern. A flute-like and upward-spiraling sound is characteristic of this Swainson's Thrush. Quite a contrast to the plaintively whistled notes of a Black-capped Chickadee. Maybe your bird has a raspy quality to its trill, like a Willow Flycatcher, while the ratchety song of a Marsh Wren cuts its way through the dense vegetation of a cattail marsh. Learn more at BirdNote.org.

Ridgway's Rails on San Francisco Bay May 20, 2022

Once abundant around San Francisco Bay, the Ridgway’s Rail — formerly known as the California Clapper Rail — is now endangered. In the 19th Century, unregulated hunting plundered the species. In the 20th Century, rampant development reduced salt marsh habitat by 85%. But in the 21st Century, the Ridgway’s Rail has allies. Restoration is under way to increase healthy saltmarsh habitat for these endangered birds. Also, efforts to control the number of predatory cats are improving the chances for the Ridgway’s Rail to survive. Learn more at BirdNote.org.

Haley Scott on Leading Bird Walks May 19, 2022

Haley Scott leads bird walks with the Feminist Bird Club in New York City. And she tries to make her walks comfortable for newcomers and experienced birders alike. “We’re all in the process together, we’re all learning the birds together,” she says. She values the inclusive approach of the Feminist Bird Club and makes sure that participants, especially people from historically excluded backgrounds, feel welcome on her walks. Learn more about the Feminist Bird Club here.

Phainopeplas Glisten May 18, 2022

A slim, sleek bird with a spiky crest, Phainopepla comes from the Greek for “shining cloak.” The name refers to the male’s glistening, inky black feathers, which are set off by piercing red eyes. And if the Greek name isn’t helping you picture it, a common nickname might: the goth cardinal. From February to April, they nest in pairs in the arid Sonoran Desert. From May to July, they form nesting colonies in leafy oak and sycamore canyons to escape the summer heat. Learn more at BirdNote.org.

Bring Birds Back Season 2 May 17, 2022

Last year, Tenijah Hamilton discovered her love of birds – and found out that birds are in trouble. On a mission to help bring birds back, Tenijah joined bird enthusiasts from different backgrounds, identities, and communities to learn and share simple, everyday actions people can take to help the birds that bring us all joy. Follow Tenijah's journey as Bring Birds Back returns for a second season on May 18th - she brings more tips and helpful information about what we can do to make the world a better place for birds and humans.

Preening 101 May 17, 2022

If a bird’s feathers get too dried out, they become brittle. To prevent that from happening, most birds have a gland located above the base of the tail that produces oil. They use their beaks to massage oil from the gland into their feathers to keep them supple. A bird first grips a feather in its beak near the feather’s base. Then it slides its beak along the length of the feather toward the tip. This action smoothes together the tiny structures—called barbules—that make up the feather, while also removing dirt and small parasites. Learn more at BirdNote.org.

Rock Climbing Among the Peregrines May 16, 2022

Eagle Cliff in New Hampshire’s Franconia Notch State Park is an important nesting site for Peregrine Falcons. Each year, popular climbing routes in the area close temporarily to give nesting falcons their space. After peregrines disappeared from the northeast due to the pesticide DDT, Eagle Cliff was the first natural rock face to host a successful peregrine nest. Now, state agencies and New Hampshire Audubon work with rock climbing groups to decide when to close cliffs in the summer. Learn more at BirdNote.org.

Gannets and Dolphins May 15, 2022

Northern Gannets, fish-eating seabirds, dive headfirst into the ocean at speeds of up to 60 miles an hour, pursuing their prey. Sometimes, they get help. Dolphins herd fish into dense, frantic concentrations near the surface, while gannets take advantage and plunge into the shoals from aloft. Scientists call this a multispeciesfeeding association, a frequent phenomenon on the ocean’s surface. This may seem like evidence of cooperation between species, but it’s more about opportunity. Kittiwakes and gulls, as well as seals and whales, may join in, too. Learn more at BirdNote.org.

Morning on the Bayou May 14, 2022

Cypress trees draped with Spanish moss rise from still, dark water. A Barred Owl hoots mightily as an alligator slithers by. It's morning on the bayou. Bayous are found in much of the Southeast from Arkansas to Alabama, across flat land that drains into the Mississippi River. A bayou's luxuriant wetness supports lush growth of trees and shrubs. These in turn offer secluded nesting for a broad range of birds, including the Anhinga, the Yellow-throated Warbler, and this Yellow-crowned Night-Heron. Learn more at BirdNote.org.

Bird Facts Stranger Than Fiction May 13, 2022

Novelist Kira Jane Buxton has written several books about a pet crow navigating a post-apocalyptic world. But her writing is full of real-world bird behaviors. She has taken inspiration from how sparrows line their nests with cigarette stubs — which can deter mites — and many other bits of animal trivia. “I maintain that anything I took liberties with, in terms of the more fantasy or fantastical elements of the novel, they're not half as exciting as what's really happening in nature,” she says.

A Marsh With More Than One Purpose May 12, 2022

The Arcata Marsh and Wildlife Sanctuary in Northwest California is an important stop along the Pacific Flyway, one of the four main routes for bird migration through North America. Visitors are sometimes surprised to learn that this wildlife sanctuary is also the city of Arcata’s wastewater treatment facility. By combining conventional wastewater treatment to natural wetlands, the city has created habitat homes and migratory resting places for over 300 species of birds, including many shorebirds.

Tiniest Bird on the Continent May 11, 2022

The tiniest bird in continental North America: the Calliope Hummingbird - a 3-1/4-inch jewel, weighing in at just a tenth of an ounce. These birds migrate north each spring from Western Mexico. From its perch, a male Calliope Hummingbird surveys its territory. This exquisite bird was named for the Greek muse of epic poetry, and it's the smallest long-distance avian migrant in the world. Learn more at BirdNote.org.

Ada Limón: The Hurting Kind May 10, 2022

Poet Ada Limón often writes about birds, and her new book, The Hurting Kind, is no exception. Birds are a throughline in the book — between the seasons, from childhood to present, and knowing and unknowing. Two of her poems examine opposite sides of the “knowing/unknowing” coin. You can read many more fantastic poems, with and without birds, in Ada Limón's new book, The Hurting Kind.

BirdNoir - That Raptor’s an Impostor! May 09, 2022

In this episode of BirdNoir, the Private Eye gets a call from his friend Frank, his eyes and ears in the neighborhood. He’s hearing a Red-shouldered Hawk call, but there’s no hawk in sight. Going through the lineup of usual suspects found in backyards, they examine the surprising talent for mimicry found among common birds and finally put the finger on the trickster. Learn more at BirdNote.org.

Wood Ducks Succeed May 08, 2022

Your eye may be drawn to the gorgeous male Wood Duck, but it is the call of the modestly plumaged female you’ll hear. This call tells the male where his mate is, important as the pair stays together through much of the winter and spring. Wood Ducks are among a small number of North American waterfowl that nest in cavities, and many of them nest in boxes we provide for them. Learn more at BirdNote.org.

The Perfect Nestbox May 07, 2022

Many native cavity-nesters - including this Black-capped Chickadee - will nest in an artificial birdhouse, or nestbox. Look for a nestbox that's plain wood. If the birdhouse comes with a perch, remove it. It just makes it easier for a predator bird to land and go after the eggs or young. Here's the important part: the entrance hole should be 1-1/8 inches. No more, no less, exactly 1-1/8 inches. That size will let native birds in, and keep non-natives out. Now hang the nestbox out of the way of predators. You can buy a nestbox - or build your own! Learn more at BirdNote.org.

Thick-billed Longspur May 06, 2022

It can feel like there’s nowhere to hide in the shortgrass prairie. But the Thick-billed Longspur calls this place home. The bird’s burbling song helps create the high plains’ soundscape. The species was formerly named McCown’s Longspur after a Confederate general who participated in genocide against Native Americans. In 2020, after pressure from the “Bird Names for Birds” movement and others, the species was renamed for its thick bill, which is pale on females and black on breeding males. Learn more at BirdNote.org.

Which Bird Has the Most Feathers May 05, 2022

In general, the bigger the bird, the higher the number of feathers. Someone counted the feathers on a Tundra Swan and came up with 25,216. At least 80% were on the swan’s neck. Penguins, on the other hand, have lots of small feathers all over their bodies. The largest species is the Emperor Penguin, and one project counted around 80,000 feathers on a single bird. That’s nearly sixty per square inch – keeping the penguin insulated and waterproof in harsh climates. But the most feathered creature ever? It may have been a dinosaur! Learn more at BirdNote.org.

The Wild Parrots of San Francisco May 04, 2022

Flocks of Cherry-headed Conures, a species native to South America, are now found throughout San Francisco. While a local legend claims that a pet shop owner introduced them by burning the shop down, it’s more likely that that a few of these loud-mouths exasperated their owners until they “accidentally” left a window open. Sadly, wild Cherry-headed Conures are falling ill from rodent poison. A nonprofit, Mickaboo, adopts out healed rescues. Learn more at BirdNote.org.

Ponderosa Pine Savanna May 03, 2022

In a Western ponderosa pine savanna, tall pines dot an open, grassy landscape. A Western Bluebird flits from a gnarly branch, as this Cassin's Finch belts out a rapid song. The trees here grow singly or in small stands. Upslope, the pines become denser, mixing with firs. Downhill, the trees give way to an open grassland. The open structure of this savanna, found on mountain slopes from the Rockies to the Cascades, results from recurring natural fires. Fast-moving blazes sweep through, burning the low vegetation but sparing the larger trees, which are protected by very thick bark. After a fire, grass and wildflowers re-grow quickly. Learn more at BirdNote.org.

Noppadol Paothong on Conservation Photography May 02, 2022

Growing up in Thailand, Noppadol Paothong loved the outdoors, and began learning about cameras at just eight or nine years old. He came to the U.S. to study graphic design, but the woman who’s now his wife encouraged him to pursue photography instead. While working at a daily newspaper, he took his first photos of Greater Prairie-Chickens. He’s now a staff photographer for the Missouri Department of Conservation and has produced two books about species of grouse that depend on grasslands. Learn more at BirdNote.org.

What’s a Beak Made Of? May 01, 2022

Bird beaks, or bills, come in many shapes and sizes. And birds use them for just about everything: to collect food, preen, fight, court, chop holes in trees, weave nests, and more. In order for a bird to fly, its beak must weigh as little as possible. Beaks are covered with a sheath of a tough material called keratin, which grows continuously because a beak wears down with use. Learn more at BirdNote.org.

Cactus Wren Nest Orientation Apr 30, 2022

Cactus Wrens, which may nest several times between March and September, carefully orient their nests in tune with the season. These bulky twig structures have a side entrance that curves toward the inner chamber. When building a nest for the hot months, the wren faces the opening to receive the afternoon breeze. By contrast, a Cactus Wren building a nest in early March orients the entrance away from the cold winds of that season, keeping the chicks snug and warm. Learn more at BirdNote.org.

Joyce Clement: Birds Punctuate the Days Apr 29, 2022

Poet Joyce Clement writes haiku, a traditional Japanese form. While it's often thought of as having three lines with 5-7-5 syllables, Joyce says that the key elements of any haiku are a fragment and a phrase spoken in a single breath. In this sequence of haiku, Joyce juxtaposes punctuation marks with images of birds, drawing on their similar appearances, as well as meaning. Learn more at BirdNote.org.

Birds Dress for Spring Apr 28, 2022

It's spring! And for many birds, a time to look their best to attract a new mate. This American Goldfinch has recently molted. Its old, worn-down feathers have fallen out, and new ones have grown in. When goldfinches molt in the fall, they lose these brightly colored feathers. Their winter camouflage helps them blend in with the drab background of the season. Learn more at BirdNote.org.

Puffin Bills Glow Apr 27, 2022

Puffins are known for their flashy bills, striped like a giant piece of candy-corn. New research has found that the bills of Atlantic Puffins glow brightly under ultraviolet blacklights. Neon, curved streaks appeared between the different colored segments of a puffin’s bill in this lighting. It’s possible that the UV highlights help the birds further stand out to potential mates. For the experiment, researchers made special puffin sunglasses to protect the birds’ eyes. Learn more at BirdNote.org.

Making a Home Among the Saguaros Apr 26, 2022

In the arid Arizona desert, where cacti thrive but trees are scarce, the Gila Woodpecker and Gilded Flicker carve out nest cavities in living saguaros. Tall, old saguaros may be pocked with twenty or more nest holes, bearing witness to decades of woodpecker families. The woodpeckers excavate a new nest every year, leaving the old, now-empty cavities behind. But they don't stay empty for long. Elf Owls, Ferruginous Pygmy-Owls, Purple Martins, and Brown-crested Flycatchers all find the slightly used woodpecker cavities superb nest sites. Learn more at BirdNote.org.

Sooty Grouse are Hooting Apr 25, 2022

In spring, a male Sooty Grouse calls from a concealed perch high in a tall conifer. Known as “hooting,” it’s a very low-pitched, five or six-note thunking sound. When a female cackles in response, the male flies down and displays to her by strutting and fanning his tail. Females are camouflaged in shades of gray and brown. One of the best times to see a Sooty Grouse is mid-summer, when the female escorts her chicks to the edge of a trail or roadside to search for food. Learn more at BirdNote.org.

Seabirds Drink Salt Water Apr 24, 2022

Seabirds have no problem drinking sea water. The salt they take in is absorbed and moves through their blood stream into a pair of salt glands above their eyes. The densely salty fluid is excreted from the nostrils and runs down grooves in the bill. As the drop gets larger, the bird shakes its head to send the salt back to the ocean. A seabird's skull has a pair of grooves for the salt glands right over the eyes. Learn more at BirdNote.org.

Sharp-tailed Grouse on a Lek Apr 23, 2022

During spring at Lostwood National Wildlife Refuge in North Dakota, male Sharp-tailed Grouse - like the one pictured here - perform their elaborate mating dances on a matted patch of ground called a lek. They stomp their feet, extend their wings, and zip around the lek. Then, in an instant, they stop – stock-still. All this to impress the female grouse observing from the sidelines! This wondrous, strange display is rare. Throughout the world, very few species of birds, perhaps fewer than 100, use leks when breeding. Learn more at BirdNote.org.

A Small Park That Has What Birds Need Apr 22, 2022

Washington Square Park in Manhattan is just 10 acres. But Georgia Silvera Seamans, who leads wildlife surveys there, says there’s a spot that draws in many birds because of its well-developed forest canopy. Georgia is the director of an organization called Washington Square Park Eco Projects that provides environmental education and advocates for the ecological value of the park. She collects stories from city dwellers about their experiences with birds on her podcast, Your Bird Story.

An Enormous Eagle Evolves Apr 21, 2022

Evolution on islands can produce unusually large species. Haast’s Eagle lived on the islands now known as New Zealand. With a wingspan of 9 feet and weighing up to 30 pounds, the eagle hunted the moa — a flightless bird that stood over ten feet tall. The eagles probably vanished not long after their moa prey went extinct, about 500 to 600 years ago. A site called the Cave of the Eagle contains Maori paintings of Haast’s Eagles, preserving the legacy of this immense raptor. Learn more at BirdNote.org.

Surviving Hail Storms Apr 20, 2022

As it began to hail, Marlon Inniss saw several Canada Geese doing something odd. Rather than trying to shield their heads, the geese pointed their bills skyward, directly into the path of the hail. The geese were pointing the smallest surface area of their sensitive bills, the narrow tip, into the hail — minimizing the impact. Inniss’s video of the behavior helped reaffirm an observation made by naturalist Aldo Leopold one hundred years before of Northern Pintails adopting the same stance. Learn more at BirdNote.org.

A Cardinal That's Half Male, Half Female Apr 19, 2022

In Texas, Pennsylvania, and elsewhere, people have reported seeing Northern Cardinals that are red on one side and brown on the other, indicating that a bird is half male and half female. This anomaly occurs in other species of birds, as well, not just cardinals. Insects, too! Scientists call these bilateral gynandromorphs. Learn more at BirdNote.org.

BirdNoir: The Wild Tom Turkey Apr 18, 2022

In this episode of BirdNoir, the private eye gets a call from H. Jon Benjamin about unusual Wild Turkey behavior. A male turkey (known as a “tom”) won’t leave his car alone. He keeps tapping his beak on the car. Then the turkey starts circling the house and looking in all the windows. The private eye reveals how things look from the turkey’s perspective, which points the way to a possible solution. Learn more at BirdNote.org.

Wood Buffalo National Park - Birthplace of Whooping Cranes Apr 17, 2022

In Canada, where Alberta meets The Northwest Territories, lies Wood Buffalo National Park, where endangered Whooping Cranes dance, nest, and raise their young. It's a "place of superlatives,” says park superintendent Rob Kent. “Visitors can see pristine ecosystems, 5,000 bison, 150-pound wolves, and the largest freshwater delta in North America.” When summer ends and the juvenile cranes are able to fly, they migrate 2,700 miles to their wintering grounds on the Gulf Coast of Texas.

Nocturnal Migration of Songbirds Apr 16, 2022

If this week's bright full moon pulls you outside, pause for a moment and listen. You might hear migrating songbirds overhead. Most songbirds migrate at night, when fewer predators are out. The migrants stop, feed, and rest during the day. However, many scientists believe that the main reason songbirds migrate at night is that the stars help orient them on their journey.

Audio Postcard from the Kyiv Zoo Apr 15, 2022

Today, we’re sharing a glimpse of what it was like in mid-March at the bird exhibits in the Kyiv Zoo. Workers at the zoo stayed to take care of the animals during the Russian invasion. They worked long days, doing what it took to keep a zoo running: cleaning stalls and preparing food. They returned to bomb shelters to sleep at night. Julia Vakulenko of the Kyiv Zoo shared recordings of her coworkers caring for the zoo’s birds. Learn more at BirdNote.org.

How Cliff Swallows Build a Nest Apr 15, 2022

When Cliff Swallows arrive on the breeding grounds in North America, the dirty work begins. The swallows scoop up mud in their beaks and carefully build a gourd-shaped nest with a tapered opening. They add a lining of dry grass to keep eggs warm. It takes days of work and a thousand mouthfuls of mud to finish a single nest—and it’s just one part of a large colony. Learn more at BirdNote.org.

Rachel Carson and Silent Spring Apr 14, 2022

Among the most welcome features of spring is the renewal of bird song. Can you imagine a spring without the voices of birds? The silence would -- as they say -- be deafening, the absence of their songs like the loss of one of our primary senses. Rachel Carson's 1962 book, Silent Spring, helped found the modern environmental movement. When you hear the birds (like this Spotted Towhee or its cousin, the Eastern Towhee) sing this spring, remember Rachel Carson, and be grateful. You can learn more at RachelCarson.org.

Donika Kelly and the Bowerbird Apr 13, 2022

A number of years ago, poet Donika Kelly was trying to figure out how to date, when she saw a nature documentary about a bowerbird. Male Satin Bowerbirds will gather all the blue items they can find, build a beautiful structure called a bower, and do a dance to try to woo the females. Donika found herself wishing that human courtship had such a clear structure, and wrote a series of poems inspired by the bowerbird. Learn more at BirdNote.org.

Kinglet Fireworks Apr 12, 2022

Most of the time, a Ruby-crowned Kinglet is neither ruby nor regal. A tiny songbird washed in faded olive-green, the male shows a hint of crimson atop of his head — hardly a ruby crown. But don’t forsake the kinglet for flashier birds. When courting a female or dueling with another male, the kinglet exposes those ruby feathers, and his crown glows with the feathery fireworks that give the bird its name. Now is the time to look for kinglets, as they migrate north across much of the continent toward breeding sites in remote evergreen woods. Learn more at BirdNote.org.

Planting Oaks for Birds Apr 11, 2022

Oak trees are an important resource for birds finding insects to feed their young. It takes thousands of caterpillars from an oak tree to raise a single nest of baby birds. By planting an oak species native to your area, you can help ensure that birds are able to raise their young successfully.

Burrowing Belted Kingfisher Apr 10, 2022

The Belted Kingfisher dashes through the air, warning intruders with its rapid-fire, rattling call. In spring, the best places to see Belted Kingfishers are along sandy banks -- they are busy digging burrows, where they will nest. The holes typically reach three to six feet into the bank, but some nesting holes can extend fifteen feet. Learn more at BirdNote.org.

You Could Take a Pigeon to the Movies Apr 09, 2022

A movie runs at 24 frames per second, just right for humans to sense as normal speed. Pigeons process the visual world several times faster. The frantic car chase that puts us at the edge of our seats would likely appear—to a pigeon—more like a slideshow or PowerPoint. A bird’s rapid-fire perception is vital to its staying alive, whether it’s hunting fast-moving prey or eluding speedy predators. From the pigeon’s perspective, humans live in the slow lane.

I Dream of Grosbeaks Apr 08, 2022

Science educator Chidi Paige was working hard preparing her students for the World Series of Birding. Chidi’s students were studying with the goal of identifying the most birds in the kid’s competition. And then something happened that made Chidi wonder if they were thinking about birds a little too much: one of the students began seeing a Rose-breasted Grosbeak in her dreams. The dream ended up having unexpected relevance in the competition. Learn more at BirdNote.org.

Unlikely Places to Go Birding Apr 07, 2022

Birding is often best in the least likely places. At sewage treatment plants, watch for ducks and gulls - and raptors keeping watch over them all. Another place might be your local landfill or dump. The Brownsville, Texas dump was, for years, the only place in the US you could find this Tamaulipas Crow. For a more sedate birding adventure, visit a cemetery. Especially in rural areas and in the Midwest, cemeteries are often repositories of native plants, and thus magnets for migratory birds, which find food - and cover - in those green oases.

The Cool, Rugged Life of a Snow Bunting Apr 06, 2022

The Arctic is still wintry when male Snow Buntings return to nesting areas in April. There's a big benefit to arriving early enough to claim a prime nest cavity in a rock face or under boulders, where it will be safer from predators. Nesting in chilly rock cavities means extra care must be taken to keep eggs and nestlings warm. That’s why, unlike many other bird species, female Snow Buntings never come off the nest. The males bring them food, giving them more continuous time on the eggs. Learn more at BirdNote.org.

Ada Limón and the Birds of Kentucky Apr 05, 2022

When poet Ada Limón moved to Kentucky with her husband for his work, she was having trouble adjusting to her new home. To connect with the place, she began learning about the local birds and plants. She found comfort in the idea of the nearly omnipresent state bird, the Northern Cardinal. That inspired a poem in which the state bird becomes a metaphor for love. Learn more at BirdNote.org.

Adopt a Tree to Save the Birds Apr 04, 2022

Many birds depend on caterpillars often found on trees lining city sidewalks. But few insects spend their whole lives on the tree: the next stage is in the leaves and soil under the tree. In cities, that habitat is often compacted and leafless. By adopting a tree and creating a “soft landing” for caterpillars, anyone can help keep birds supplied with the insects they need to survive.

Walk Down an Arroyo Apr 03, 2022

Arroyo means "stream" in Spanish. With mesquite, yucca, and cactus along their edges, arroyos in the Southwest fill with water only a few times a year, mostly during the heavy rains of late summer. There's a remarkable diversity of wildlife here, including this Pyrrhuloxia. Birds here are most active in the morning, except those that are nighttime specialists. The sounds of life in an arroyo are magical, day and night. Learn more at BirdNote.org.

Hovering with Horned Larks Apr 02, 2022

Horned Larks rival meadowlarks as the most colorful birds of North American grasslands. They live in prairies, fields, and tundra, but agriculture and development now intrude on many of the Horned Lark's traditional nesting areas. The farmland Conservation Reserve Program encourages agricultural landowners to plant resource-conserving vegetation. This practice protects topsoil and provides habitat for birds like the Horned Lark, as well as other wildlife. Learn more at BirdNote.org.

Bird...NOT! with H. Jon Benjamin Apr 01, 2022

During the COVID-19 pandemic, actor H. Jon Benjamin began sharing his experiences with birds in his “Morning Bird Report” videos on social media. For April Fools Day, BirdNote has invited him to test out his birding-by-sound skills on a one-of-a-kind quiz show: Bird…NOT! Jon has to guess whether the sound is a bird or not — which isn’t always as easy as it sounds. Learn more at BirdNote.org.

Those Raucous Jays Mar 31, 2022

A raucous call and a bold flash of blue at your feeder means a jay has arrived. East of the Rockies, your visitor is quite likely a Blue Jay (left). Out west, you're probably seeing a Steller's Jay. These daring blue dandies sound the alarm, announcing the approach of a predator. Often the loud call sends the predator packing. If not, a family of jays may gang up and mob the intruder. And, if that doesn't work, the jay may mimic the call of a Bald Eagle or Red-tailed Hawk -- birds at the very top of the pecking order -- to dissuade the invader. Learn more at BirdNote.org.

Listening From Inside the Egg Mar 30, 2022

Shorebird chicks hatch into a dangerous world, so they need to be vigilant from the start. Researchers in Australia noticed that some shorebird chicks began chirping in their final days in the egg. The chirps fell silent when the researchers played recordings of a Little Raven, which hunts for young birds. The finding suggests the chicks are listening carefully and may be able to tell threatening sounds from non-threatening ones. Learn more at BirdNote.org.

Montezuma Oropendola - The Golden Pendulum Mar 29, 2022

In a clearing where an ancient Mayan city once stood, the Montezuma Oropendola perches and sings. His courtship display is astonishing: he swings by his feet and sings, his tail describing a golden pendulum - the very source of his name in Spanish - oropendola. Learn more at BirdNote.org.

Beautiful and Beneficial Gardening for Birds Mar 28, 2022

Buying enough birdseed to keep all your backyard birds satisfied can run up a big bill. Homegrown National Park® co-founder Douglas Tallamy says that growing native plants in your garden can provide a balanced diet for birds. While there’s a misconception that native plants lead to a messy garden, Tallamy explains that native wildflowers, shrubs and trees can provide both splashes of color and nutritious meals for birds.

Eagles Rebuild Mar 27, 2022

Bald Eagles build large stick nests in tall trees. These nests endure rough treatment. Rambunctious chicks pull sticks out and flap madly, holding on with their feet, before they fledge. Wind buffets the nest year round. But eagles reuse their nests year after year. Adult eagles break off dead limbs and carry them back to their nests. Bald Eagles have been known to carry sticks more than a mile to their nest. Learn more at BirdNote.org.

Thirsty Hummingbirds Mar 26, 2022

Here they come! Rufous Hummingbirds, Black-chins, Broad-bills, Ruby-throats like this one, and others are migrating north after a hot, dry winter in sunny Mexico or Central America. And they’re ready for a drink. You can help these thirsty birds by hanging a hummingbird feeder filled with the right kind of nectar. Select a feeder that you can easily clean on the inside, and one that has plenty of red to attract the birds. Then fill it with sugar water made by dissolving one part sugar in four parts water (use plain table sugar — no honey or sugar substitutes allowed). And please — no red food coloring!

Singing with Fox Sparrows Mar 25, 2022

A modest thicket of trees along a street can be the perfect place to hear one of the earliest bird songs of spring: the Fox Sparrow. You can hear their loud, spirited songs from dense vegetation throughout much of the U.S. The easternmost birds have the rufous color of a Red Fox. Others found further west are a mix of brown, rust and gray. The stocky sparrow reveals itself by vigorously kicking the leaf litter with both feet. Learn more at BirdNote.org.

Rivers of Birds Mar 24, 2022

One of the world champions of long-distance migration is the Arctic Tern. Arctic Terns nest across the far northern reaches of the continent during our summer, then fly south to Antarctica for the rest of the year. Some will circle the polar ice-pack before heading north again, completing a total round trip of more than 50,000 miles. Every year. Learn more at BirdNote.org.

The Brown Thrasher's Never-Ending Songbook Mar 23, 2022

The Northern Mockingbird isn’t the only mimic bird in town. Brown Thrashers also learn songs from nearby birds and add them to their repertoire. The species has been documented singing over eleven hundred different songs: a mix of imitations and invented little melodies. While mockingbirds usually repeat a song or phrase three or more times before moving on, Brown Thrashers tend to repeat a phrase only twice. Learn more at BirdNote.org.

Dawn Song - Emily Dickinson Mar 22, 2022

Emily Dickinson: "The Birds begun at Four o'clock..." As the first rays of sunlight fill the trees on a spring morning, a symphony of birdsong erupts. As early morning light extinguishes the stars, male birds begin to belt out their songs. One of the magical gifts of spring is the dawn song. Early in the morning, sparrows, chickadees, thrushes, finches, wrens, blackbirds, and warblers - like this Yellow Warbler - all sing at once. Learn more at BirdNote.org.

Creating Bird Habitat at Home Mar 21, 2022

One of the biggest threats to birds is the decline in biodiversity due to habitat loss — and the traditional, manicured lawn isn’t helping. Growing native plants in your yard allows you to protect birds at home, says ecologist Douglas Tallamy, who co-founded an organization called Homegrown National Park® to help people transform their lawns into havens for wildlife.

Celebrating the Vernal Equinox Mar 20, 2022

The vernal equinox, the first day of spring. The moment when the sun is directly above the equator, and day and night are nearly equal all over the world. Yet birds sense the growing hours of daylight through a surge of hormones. It’s time to sing! Both science and folklore tie spring to the renewal of nature, as the world awakens from the long cold winter. Listen carefully, and you might hear the bubbling song of a tiny Ruby-crowned Kinglet, or a Bewick’s Wren tuning up, or a towhee — like this beautiful Eastern Towhee — shouting out its whistled notes.

Australia's Rainforest Birds Mar 19, 2022

The rainforests of Eastern and Northeastern Australia harbor many species of birds found almost nowhere else. This Eastern Whipbird — which is more often heard than seen — hangs out in the dense understory. Easier to lay eyes on is the large, pigeon-like Wompoo Fruit-Dove. Feathered in a stunning combination of green, purple, and yellow, this bird is clearly named for its voice. And a pig-like grunting on the forest floor tells us we’re in the company of the Southern Cassowary. Its helmet — called a casque — makes it look as much like a dinosaur as any living bird.

Female Condors Have Offspring Without Males Mar 18, 2022

A captive breeding program has helped set California Condors on the path to recovery. But when biologists reviewed the family tree for the breeding program, they found a big surprise. Two chicks had DNA that linked them perfectly to their mothers but didn’t match a single male. They arose through parthenogenesis, developing from unfertilized eggs without sperm from a male. These condors are the first case of parthenogenesis in a wild bird species where the females had access to fertile males. Learn more at BirdNote.org.

Birds Talk, People Squawk Mar 17, 2022

Darvin Gebhart is a champion goose-caller. But there are also birds that use human language. Sparkie Williams was a famous parakeet, or budgerigar, that lived in England in the 1950s. He recorded commercials for bird seed and released his own hit single "Pretty Talk." Alex, the African Grey Parrot, was another notable talking bird, with amazing cognitive abilities.

T and Dart Mar 16, 2022

Author Kira Jane Buxton loves crows — so much that she’s written two novels about a crow named S.T. navigating the extinction of humanity. When she was writing those books, she tried befriending the crows in her neighborhood, and wound up bonding with a pair of them. She named them T and Dart. T, the female, is clumsy and playful. Dart, her mate, is more aloof towards Kira but always shares his food with T. This crow couple helped inspire the fictional crows in Kira’s books. Learn more at BirdNote.org.

Black-necked Stilt - The Bird with Outrageous Legs Mar 15, 2022

Visit a shallow wetland in summer, and you might see this slender, black-and-white shorebird with outrageous red legs. The Black-necked Stilt uses its long legs for wading as it feeds on tiny insects and crustaceans on the surface of the water. Stilts are sensitive to drought, which has increased with global climate change. But they readily move to new breeding areas and respond quickly when new wetlands are created.

Danielle Whittaker and the Mystery of Bird Scent Mar 11, 2022

When biologist Danielle Whittaker started studying bird odors, some scientists tried to discourage her, claiming that birds can’t smell. But that only deepened her curiosity. Once, she caught a whiff of a cowbird, which smelled to her like sugar cookies. Danielle and her colleagues studied Dark-eyed Juncos and found that they produce many odors that help influence breeding behavior. Learn more in Danielle Whittaker’s new book, The Secret Perfume of Birds: Uncovering the Science of Avian Scent.

Identify Bird Sounds on Your Phone Mar 10, 2022

An online tool called BirdNET uses artificial intelligence to identify bird songs and calls. And Cornell’s well-known Merlin Bird ID app now has sound ID, too. It’s as simple as opening the app, choosing “Sound ID,” and hitting record. It can pick out multiple species in the same recording. Learn more at BirdNote.org.

Geese Aloft: Flock Voices of March Mar 09, 2022

Geese migrate north between February and April, making stopovers along the way to rest and eat. Most are bound for their breeding grounds in the far north. But we’ll hear them again soon, on their way back south in October. Click play and learn how to tell some North American species apart by sound! Learn more at BirdNote.org.

Games Make Bird ID Fun Mar 08, 2022

When science educator Chidi Page began teaching her students how to identify birds, she wanted a way to engage kids and help them learn quickly. Unable to find one for sale, Chidi decided to make her own game. Similar to the game “Guess Who,” players ask questions about what the game’s characters look like, such as “Does your bird have a crest?” or “Does it have an eye ring?” Chidi named the game “Which Is It,” a phrase that sounded like an inquisitive bird call.

Why a Gorget Glitters Mar 07, 2022

A hummingbird's brilliant throat feathers are called a "gorget," a term applied in past centuries to the metallic swatch protecting the throat of a knight-in-armor. Light waves reflect and refract off the throat feathers, creating color in the manner of sun glinting off a film of oil on water. The gorget of this Rufous Hummingbird is stunning!

Florida Scrub-Jay Mar 06, 2022

Thousands of years ago, rising sea levels isolated much of the Florida peninsula as an island. During that long isolation, a unique oak-scrub ecosystem developed. The Florida Scrub-Jay is one of many special animals and plants that evolved with this habitat. Because they depend on acorns during winter, Florida Scrub-Jays can survive only in oak scrub. Populations have declined because the birds have lost much of their special habitat to citrus groves, pastures, and development. Happily, many birds are now protected by the Archbold Biological Station and other preserves. But there's still more to be done! Learn more at BirdNote.org.

House Finches - Red and Yellow Mar 05, 2022

House Finches eat many kinds of seeds and fruits. A careful look at male House Finches at a feeder shows that, while most males show red feathering, some are decidedly more orange - and some even yellow. House Finches acquire their coloration from pigments known as carotenoids in the foods they eat. Learn more at BirdNote.org.

The Royal Pigeons Mar 04, 2022

Despite their modern reputation, pigeons were once beloved by royalty. Akbar the Great, ruler of the Mughal Empire in the 16th Century, kept over 20,000 pigeons. Owning pigeons in parts of Europe was a privilege restricted to the nobility. Pigeon ownership became a flashpoint during the French Revolution, when commoners finally gained the right to raise pigeons.

Great Tinamou, Eerie Voice in the Jungle Mar 03, 2022

The eerie sound of the Great Tinamou can be heard in the lowland jungle throughout much of Central and South America. Secretive — and almost impossible to see — Great Tinamous call early and late in the day. And their voices carry a long distance. Learn more at BirdNote.org.

The Warbler That Loves Pines Mar 02, 2022

The Pine Warbler is one of the few warblers that make appearances at bird feeders. They live year round in pine forests of the southeast U.S. and several Caribbean islands. Early spring is a good time to see them migrating through cities in the Midwest and the East Coast. If there’s a pine or two nearby, look for them picking through pine needles for food. Their song, heard throughout the year, is a sweet-sounding trill. Learn more at BirdNote.org.

The Great Horned Owl Nest Mar 01, 2022

When Great Horned Owl eggs hatch, the downy owlets are the size of newborn chickens. Their mother broods them day and night. A few weeks later, the owlets can be left alone while both adults resume hunting at twilight. Great Horned Owl young remain in the nest for about six weeks, then climb out onto nearby branches. They begin taking short flights at seven weeks, and can fly well at 9-10 weeks. Learn more at BirdNote.org.

White-tailed Hawks on the Texas Coastal Plain Feb 28, 2022

The White-tailed Hawk thrives in the grassy plains of the Texas Coastal Plain, where many tropical species reach the northern limit of their ranges. White-tailed Hawks often hunt by kiting: hovering like a kite in the breeze with the wings held in a “V” above the body, dropping suddenly on their prey. When a grass fire breaks out, they hunt small animals fleeing from the fire’s edge. Learn more at BirdNote.org.

Nest Cavities - Book Early Feb 27, 2022

Tree Swallows and bluebirds — like this Western Bluebird — are among the earliest northbound migrants to arrive, heralding spring a month before the equinox. These species will nest only in cavities, such as old woodpecker holes or man-made nestboxes. But the supply of specialized nest sites is limited, and competition is intense. By arriving early, these swallows and bluebirds improve their chances of securing unoccupied cavities. To learn more about building nestboxes, visit BirdNote.org.

Leaping with Sandhill Cranes Feb 26, 2022

With a graceful leap, wings outstretched, Sandhill Cranes welcome the longer days. The stately cranes are courting, renewing an annual dance they perform in earnest as the days lengthen into spring. Sandhill Crane pairs remain together for life, and their spirited dance plays an essential role in reaffirming this bond. Learn more at BirdNote.org.

The Nasally Fish Crow Feb 25, 2022

The harsh caws of American Crows are one of the most familiar bird calls in North America. Fish Crows sometimes join flocks of American Crows as they forage for food. The two crow species look similar, but have a distinct call that sounds a bit like an American Crow with a stuffy nose. The Fish Crow is found in much of the eastern U.S. and is spreading to new areas north and west to breed. Learn more at BirdNote.org.

Spark Bird: Rodney Stotts on Bringing Eagles Back to DC Feb 24, 2022

Rodney Stotts is a master falconer who teaches people of all ages about raptors. In the 1990s, he helped reintroduce eagles to the Anacostia River, which runs through Washington, DC. As part of the Earth Conservation Corps, Rodney helped take care of eagle chicks sent from Wisconsin, where the species was more plentiful. Now, Bald Eagles consistently nest along the river, meaning that people living nearby can enjoy them. Learn more at BirdNote.org.

Flying with Birds and Bats Feb 23, 2022

Bats and birds have evolved very different ways of flying. Birds have stiff feathers projecting from lightweight, fused arm and hand bones; bats have flexible wings of membranes stretched between elongated fingers. While birds use the strong downstroke of their wings to fly, bats support their weight on the upstroke, too, by twisting their wings backward. Bats tend to be more agile in flight, while many birds can fly with greater speed. Learn more at BirdNote.org.

Flocking and Foraging Feb 22, 2022

In winter, a foraging flock might include several species of birds: chickadees, kinglets, and even a Downy Woodpecker. Many bird species eat alone, so you might wonder why these birds have chosen to dine together. Different species foraging in a group to find food enhances the success of all. One species assists the foraging of others. It's known as "commensal feeding." And more eyes and ears help protect the flock, too. Learn more at BirdNote.org.

Meet the Robo-Penguin Feb 21, 2022

Gentoo Penguins are the fastest penguins in the world. A group of researchers used the penguin’s streamlined shape to design a new undersea robot called the Quadroin. This robo-penguin has sensors to measure ocean conditions and currents. It’s particularly suited to studying eddies, which are smaller and short-lived than major ocean currents but help draw nutrients to the ocean surface, supporting the marine food web.

Falcons, Parrots, The Tree of Life Feb 20, 2022

Scientists have puzzled for centuries over how different groups of birds are related. Did birds that look physically alike, such as falcons and hawks, arise from a common ancestor, or did they reach those similarities independently? This line of inquiry was given an immense boost in recent years when an international research team unraveled the genetic codes of 48 species of birds. The results are emerging, including a revised evolutionary tree for birds that places falcons such as this American Kestrel — and parrots such as this Rainbow Lorikeet — on adjoining branches.

Jacana - Lily-trotter Feb 19, 2022

The strange wading birds known as jacanas are nick-named "lily-trotters" for their ability to walk on lilypads. In Jamaica, they're known as "Jesus birds," because they appear to be walking on water — a feat made possible by their long toes. But that's not all that's cool about jacanas. The males, including the Comb-crested Jacana pictured here, can carry their young under their wings. Picture this colorful wading bird, crouching down and spreading his wings. The young scoot in under him, and he sweeps them up and carries them off, tiny legs dangling from under his wings. Learn more at BirdNote.org.

Finding Food When it Snows Feb 18, 2022

Fresh-fallen snow is beautiful, but it poses a challenge to birds. The ground where they found food is now covered by several inches of snow. Birds such as juncos and other sparrows flit under bushes where snow doesn’t cover the ground. Finches and chickadees pick at the seed heads of plants sticking out above the snow, while robins (like this American Robin) seek out dried fruits. Nuthatches and woodpeckers cling to trees as they search for insects within the bark. Learn more at BirdNote.org.

Sandgrouse - Desert Water-carriers Feb 17, 2022

Sandgrouse live in some of the most parched environments on earth. To satisfy the thirst of their chicks, male sandgrouse carry water back to the nest in a surprising but effective way: by carrying it in their feathers. Thanks to coiled hairlike extensions on the feathers of the underparts, a sandgrouse such as this Burchell's Sandgrouse can soak up and transport about two tablespoons of liquid. The sandgrouse chicks use their bills like tiny squeegees, “milking” their father’s belly feathers for the water they need. Learn more at BirdNote.org.

Trumpeter Swans Rebound in Arkansas Feb 16, 2022

Trumpeter Swans weigh over 25 pounds and measure about five feet from beak to tail. They were nearly hunted to extinction by the turn of the twentieth century. In Arkansas, a small flock of Trumpeter Swans began spending the winter at Magness Lake in the 1990s. It has now grown to one of the biggest winter swan flocks in the Southeast. In recognition of its value to the swans, Magness Lake has been designated an Important Bird Area. Learn more at BirdNote.org.

Dining with Sanderlings Feb 15, 2022

While many shorebirds have gone south, tiny sandpipers called Sanderlings are easy to find on winter shores. They follow the waves as they lap in and out, probing the swirling sand for prey. They often eat various small crustaceans such as mole crabs, isopods, and amphipods. But they also enjoy miniature clams, polychaete worms, and horseshoe crab eggs. They’ll even catch flying insects or eat plant matter. Learn more at BirdNote.org.

Raven's Love Song Feb 14, 2022

Ravens are seen as tricksters in many traditions. But Common Ravens have a softer side. During courtship, a pair will often sit side by side, sometimes preening each other's feathers. And during that ritual, one or both may make soft warbling sounds. Raven nestlings sometimes make this same sound after they've been fed. Compared to the usual raucous raven calls, this one is soothing. It's called a comfort sound. Learn more at BirdNote.org.

Franklin's Gull - The Half-time Seagull Feb 13, 2022

Gulls are often called "seagulls," but many spend a lot of time far away from the sea. The Franklin's Gull breeds in freshwater wetlands more than 5,000 miles from its winter home at the ocean. After the breeding season, they ascend high in the sky for their long flight across the Equator to the coasts of Peru and Chile. Now deserving the name "seagull," the Franklin's Gulls roost on the beach and dive for anchovies in the cold Humboldt Current. Habitats of the world are connected by the birds that go between them. Learn more at StateOfTheBirds.org.

Birders and Hunters Feb 12, 2022

Thanks in part to the political will and financial contributions of waterfowl hunters and such organizations as Ducks Unlimited, natural wetlands that might otherwise have been lost have been preserved. Take a field trip with your local Audubon chapter to see what you can see. Maybe you'll see one of these Blue-winged Teal. You can learn more about duck stamps and how they help protect habitat for migratory waterfowl at Ducks.org.

Hovering Is Hard Work Feb 11, 2022

Hummingbirds are built for hovering flight, with flexible wrists that rotate their wings in a rapid figure-eight motion that generates almost constant lift. Eurasian Skylarks, on the other hand, hovers by fluttering its wings 10-12 times per second, singing all the while. Some raptors such as American Kestrels use a different strategy: by flying into the wind, they can float in place while they scan for prey. Learn more at BirdNote.org.

Bird Tracks in the Snow Feb 10, 2022

Look for the stories birds tell with their tracks in the snow. A crow swaggers, leaving right-and-left steps much as a walking human would. Juncos under a birdfeeder leave a hopping pattern of tiny footprints in side-by-side pairs. Look for beak marks, where a bird picked up a choice morsel or probed the ground. Tell-tale signs sometimes tell stories of life and death. You might see mouse tracks end suddenly, just where you find the imprint of an owl's wings. Find out more about animal tracking at the Wilderness Awareness School. And learn more in Bird Tracks and Sign: A Guide to North American Species, a book by Mark Elbroch.

Storm-Petrels: Myth and Reality Feb 09, 2022

Sailors once believed Wilson’s Storm-Petrels foretold a dangerous tempest. There might be a grain of truth: the tiny seabirds might find a little shelter from the gusts near a ship. Wilson’s Storm-Petrels are found in every ocean. When foraging, their feet patter across the surface, stirring up prey. Their fondness for feeding in cold, salty water could make them an indicator for changes in ocean conditions due to climate change. Learn more at BirdNote.org.

When Does a Crossbill's Bill Cross? Feb 08, 2022

A young crossbill starts life with a wedge-shaped beak. As it grows up and starts to feed itself by removing conifer seeds from their tough packaging, the tips of its bill begin to grow rapidly — and then they cross. By the time the bird is a month and a half old, the tips of its bill become fully crossed. Learn more at BirdNote.org.

Non-Vocalization: Many Ways to Make Noise Feb 07, 2022

Many birds have creative ways to make noise without using their voices. Ruffed Grouse use their wings to make echoing booms. Wilson’s Snipes make a high-pitched sound called winnowing as air passes across their tail feathers. Palm Cockatoos swing a stick against a tree to tap out a beat.

This show was produced by World According to Sound. BirdNote and World According to Sound are teaming up for an immersive, 70-minute, virtual event about the sounds of birds. Learn more at BirdNote.org.

Anna's Hummingbirds Winter in the North Feb 06, 2022

Most hummingbirds retreat south in autumn, but Anna's Hummingbirds are found in northern latitudes throughout the year. Since 1960, they've moved their year-round limit north from California to British Columbia. They're taking advantage of flowering plants and shrubs, as well as hummingbird feeders. But how do they survive the northern cold? They suspend their high rate of metabolism by entering a state of torpor – a sort of nightly hibernation, where heart rate and body temperature are reduced to a bare minimum. Many hummingbirds, including those in the high Andes, rely on the same strategy. Learn more at BirdNote.org.

American Coots Feb 05, 2022

American Coots settle onto lakes and estuaries, forming rafts of hundreds, even thousands, of birds. They like to feed on aquatic vegetation, and sometimes they lumber ashore to nibble at grasses and agricultural crops. The coot's lobed toes help it swim and maneuver under water. To get airborne, the coot requires a long, running takeoff. Be sure to watch the video of a coot feeding on the Chesapeake Bay. Learn more at BirdNote.org.

Rodney Stotts on Becoming a Falconer Feb 04, 2022

Rodney Stotts decided to become a falconer after years of working with injured raptors and teaching young people about wildlife. When he reached out to potential mentors, some couldn’t picture him, a Black man, as a falconer. But Rodney eventually found a mentor and began training and handling birds of prey. Now a certified master falconer himself, he introduces kids from the Washington, DC, area and beyond to the majesty of raptors. Learn more at BirdNote.org.

Light and Song - Sparks in Winter Feb 03, 2022

Even in winter, some birds — including Black-capped Chickadees, House Finches, and American Robins — greet the sunrise with song. We normally hear the dawn chorus in springtime, when birds sing to define territory and attract mates. But birds don’t breed by warmth alone. Day length is a far more reliable spark than weather. We know that photo-receptors in birds’ brains sense the increasing light. It triggers the production of hormones, which helps bring on the breeding season. Our early birds aren’t breeding in February. But they’re warming up. Learn more at BirdNote.org.

Conserving Wetlands for Black Rails Feb 02, 2022

Black Rails are marsh-inhabiting birds, more often heard than seen. Many Black Rails nest in marshes along the Atlantic seaboard and in the Midwest. But in winter they concentrate in the coastal marshes of East Texas, Louisiana, and Florida, areas that face many threats. US populations of Black Rails have declined greatly. In recent decades, the enactment of laws protecting wetlands has improved the bird's prospects. Still, the Black Rail remains on American Bird Conservancy's "red list." Learn more at BirdNote.org.

Spark Bird: Chidi Paige and the Yellow Warbler Feb 01, 2022

When Chidi Paige moved from Nigeria to the U.S., she began running a youth STEM program and had to teach lessons on bird identification. She was in for a challenge: she had to learn the local bird species quickly. On a birding trip, she spotted a Yellow Warbler in a pine tree. The beautiful warbler got Chidi hooked on birding. She has designed several games to make learning bird identification fun for kids. Learn more at BirdNote.org.

Biomimicry - Japanese Trains Mimic Kingfisher Jan 31, 2022

In the 1990s, train engineers in Japan built trains able to travel nearly 170 miles per hour. The problem was that when the trains exited a tunnel, the air in front of their bullet-shaped noses expanded rapidly, creating a loud “tunnel boom.” The chief engineer, a birder, looked to the shape of a kingfisher’s bill to design long, narrow train noses that parted the air. The trains became both quieter and more efficient. Learn more at BirdNote.org.

Short-eared Owl Jan 30, 2022

Flapping with deep, slow wing-motion, a Short-eared Owl appears almost to float above the ground. This owl has an extensive world range, including North and South America, Europe, and Asia. Still, it's declining, due to development, agriculture, and overgrazing. American Bird Conservancy and Partners in Flight consider this bird at-risk. But the federal Conservation and Wetland Reserve Programs are showing promise for Short-eared Owls, by preserving large blocks of habitat. Let your elected representatives know that you support these programs! Learn more at BirdNote.org.

Costa Rica Winter Sunrise Jan 29, 2022

On a winter morning in Costa Rica, a colorful choir welcomes the day. A pair of Bay Wrens sings a brisk duet just before sunrise. Perched in the upper canopy of the tropical lowland forest, a group of Keel-billed Toucans calls out. In a nearby tree, Purple-throated Fruitcrows (like this one) add their voices to the chorus. Then a male Montezuma Oropendola belts out an electrifying series of notes — one of the most distinctive voices in the tropics. Finally, a Bright-rumped Attila calls from its perch.

Unlikely Duets: Extremes of Bird Sound Jan 28, 2022

This show pairs birds that make sounds on opposite extremes: the highest-pitched bird, the Black Jacobin hummingbird, duets with the Southern Cassowary, one of the lowest-pitched birds. The faint, buzzy song of the Grasshopper Sparrow joins the voice of the White Bellbird, the loudest bird in the world.

This show was produced by World According to Sound. BirdNote and World According to Sound are teaming up for an immersive, 70-minute, virtual event about the sounds of birds. Learn more at BirdNote.org.

Why Do Birds Come to Birdfeeders? Jan 27, 2022

A tube of black oil sunflower seeds isn’t “natural”…and neither is a suet cake. Yet as soon as you hang them up, the neighborhood birds, like these female finches, find them. Those grosbeaks at your feeder probably never ate sunflower seeds in nature. Sunflowers grow in open plains, while grosbeaks live in forests. But birds have a substantial capacity to learn, either by action or by witnessing other birds at a feeder. Learn more at BirdNote.org.

Rhea Nesting Is Mind-boggling Jan 26, 2022

A typical bird nest will have maybe four to six eggs neatly arranged by the parent to hunker down on. But in one Rhea nest, you may find between 50 and 80 eggs! And they’re not all from the same set of parents. Male Rheas mate with several females and then build a single nest on the ground to hold all the eggs from each of them. Learn more at BirdNote.org.

Spark Bird: Rosemary Mosco's Bird and Moon Jan 25, 2022

Rosemary Mosco was drawn to birds as a shy child, because they rewarded patience. In college, she struggled to connect with her classes in anthropology. She began volunteering with a group in Toronto that tries to stop birds from hitting windows. At the same time, she created a cartoon about a lonely bird that befriends the moon and flies around the city having adventures. She now combines art and science as a cartoonist and science writer.

Winter Brings Falcons Jan 24, 2022

A Merlin — like this one — hunts boldly from a high perch. A Peregrine Falcon dives on a hapless pigeon, with an air speed approaching 200 miles per hour. The Gyrfalcon can fly down even the fastest waterfowl in a direct sprint. A Prairie Falcon blends in with its background. And the smallest North American falcon of all, the American Kestrel, hovers a field, watching for a mouse or large insect. Learn more at BirdNote.org.

Reddish Egret - Lagoon Dancer Jan 23, 2022

The Reddish Egret, a particularly glamorous heron, is best known for its startling antics in capturing fish. When fishing, the egret sprints across the lagoon, weaving left and right, simultaneously flicking its broad wings in and out, while stabbing into the water with its bill. Fish startled at the egret’s crazed movements become targets of that pink dagger. At times, the bird will raise its wings forward over its head, creating a shadow on the water. It then freezes in this position for minutes. Fish swim in, attracted by a patch of shade and . . . well, you know the rest. Learn more at BirdNote.org.

Nictitating Membranes - Nature's Goggles Jan 22, 2022

For most birds, keen eyesight is critical for survival. But many birds lead lives that can be very hard on the eyes — like flying at breakneck speed, racing for cover into a dense thicket, or diving under water to capture prey. Imagine how the chips fly as this Pileated Woodpecker chisels a cavity. Fortunately, birds have evolved a structure for protecting their eyes. Beneath the outer eyelids lies an extra eyelid, called the nictitating membrane. It helps keep the eye moist and clean while guarding it from wind, dust, and hazards. Learn more at BirdNote.org.

Song Sparrows Across the Continent Jan 21, 2022

Song Sparrows can be heard singing almost everywhere in the United States. People have recorded their song along rivers and lakes, in cities and towns, and in fields and forests.

On a Cold, Cold Night Jan 20, 2022

When the bitter cold of winter arrives, songbirds face an emergency: how to keep warm through the night. On normal nights, many prefer sleeping solo in a sheltered spot. But in severe cold, some kinds of birds may have a greater prospect of survival by roosting with others. Learn more at BirdNote.org.

Birds on the March with Army Ants Jan 19, 2022

As thousands of army ants march through a rainforest in Panama looking for food, countless insects try to escape. Antbirds follow the ants, waiting for flying insects to leave their hiding spots so they can swoop down and catch them. About 300 species of animals, including 29 bird species, depend on army ants for their survival. It’s thought to be the largest association of animals tied to a single species in the world.

Great Horned Owls Nest Jan 18, 2022

High in a leafless cottonwood, a female Great Horned Owl incubates two eggs. As light snow falls on her back, her mate roosts nearby. Since December, this pair has been hooting back and forth regularly at night. Great Horned Owls nest in winter, because the owlets, which hatch after a month of incubation, must remain near their parents a long time compared to many other birds — right through summer and into early fall.

Spark Bird: Kira Jane Buxton's Crow Rescue Jan 17, 2022

Kira Jane Buxton wrote two novels about a foul-mouthed pet crow navigating the extinction of humanity. But her love for crows began just a few years before writing the books. She found an injured crow surrounded by 60 others calling out in alarm. Though Kira was nervous, she took the crow to a wildlife rehabilitator. Sadly, the crow didn’t survive. But since then, Kira has bonded with her local crows and visits them regularly. Learn more at BirdNote.org.

How Evolution Reshaped the Woodcock Jan 16, 2022

Evolution works with what's at hand. So if you start with a normal bird skull – bill pointing forward, eyes oriented front or sideways, ears behind eyes – and introduce the challenge of seeing behind your head while your bill is pushed deeply into the soil, what do you get? The American Woodcock! With its long bill constantly probing the soil for earthworms, its entire skull has been rearranged. Relative to other birds, woodcocks' eyes have moved toward the top and rear of the skull, pushing the ear openings downward. Apparently the brain followed suit! Learn more at BirdNote.org.

Capuchinbirds Jan 15, 2022

The peace of the vast Guyanan jungle is abruptly broken with the dawn chorus of male Capuchinbirds, one of the most bizarre birds in South America. The singing male bows forward, then suddenly stretches to his full length, raising a monk-like cowl of feathers around his naked blue-gray head. The unmistakable noise attracts female Capuchinbirds, which jostle each other ruthlessly in the quest to get close to the studliest of the displaying males. The alpha male with the best singing technique will be the only one to mate. Learn more at BirdNote.org.

Songs in Slow-Motion Jan 14, 2022

By slowing down the songs of the Crested Oropendola (seen here) and the Tui, all the notes and harmonies stand out. While these details normally rush past the human ear faster than our brains can process, birds are alert to the subtleties of other birds’ songs.

Filming Rare Storks in Their Nests Jan 13, 2022

Photographer Gerrit Vyn traveled to northeastern India to document the daily life of the Greater Adjutant stork. These endangered birds nest high in trees on privately owned land in the state of Assam, where they’re known as Hargila. Conservation biologist Purnima Devi Barman helped Gerrit get a stork's-eye view by building a bamboo tower near the canopy of a Hargila nesting tree. Learn more in the documentary Hargila from the Cornell Lab of Ornithology.

Saving the Hargila Jan 12, 2022

Conservation biologist Purnima Devi Barman returned to Assam, India, where she grew up, to work with a highly endangered bird, the Greater Adjutant stork. The species nests in populated areas of Assam, where it’s known as Hargila. Because they’re scavengers, some see Hargila as unclean and remove trees where they nest. Purnima has found creative ways to connect Hargila to people’s daily lives and culture in Assam. Learn more at BirdNote.org.

Trogons Nest with Wasps Jan 11, 2022

The "Violaceous" Trogon (recently split into three species), which nests in Mexico, Central America, and northern South America, often excavates its dwelling within a large, active wasp or termite nest. It begins by devouring some of the insects, then digs a cavity large enough to accommodate the birds and their eggs. While they may continue to snack on resident wasps or termites throughout nesting, the trogons never eliminate all the insects, creating a nest that few predators would dare disturb. Learn more at BirdNote.org.

BirdNoir - Dial E for Eagle Jan 10, 2022

In this BirdNoir mystery, the private eye fields a call from a woman who says a large bird that looks like a Bald Eagle stole a Rainbow Trout from her pond. Through a process of elimination, the detective is able to rule out a few likely suspects and arrive at the probable answer. When you think you’ve spotted an eagle, remember to examine all the evidence. Learn more at BirdNote.org.

Tree Swallows Spend the Winter Jan 09, 2022

Most swallow species that nest in North America eat almost nothing except flying insects. When the bugs die off in the fall, the swallows head south to winter in the tropical zones of Central and South America and the Caribbean. However, Tree Swallows can also eat small fruits. If Tree Swallows arrive in the north before the insects are out, they’ll supplement their diets with fruit, giving them a competitive advantage for limited nesting sites. Learn more at BirdNote.org.

A Swirl of Snow Geese Jan 08, 2022

Snow Geese nest from far northeastern Russia to Greenland, in the arctic and subarctic. They winter in large flocks on the deltas of rivers in northwestern Washington, areas along the Eastern Seaboard, and throughout the Mississippi Flyway. Watching Snow Geese in flight, Barry Lopez described them, "as if the earth had opened and poured them forth, like a wind, a blizzard, which unfurled across the horizon above the dark soil ... great swirling currents of birds in a rattling of wings..."

Black Kites - Do Birds Start Fires? Jan 06, 2022

In the savanna country of northern Australia, the vegetation is well adapted to the area’s recurrent fires. As flames sweep across the savanna, Black Kites watch for prey like grasshoppers and lizards that flee the fire. But there’s now evidence that Black Kites may actually create fires by carrying burning twigs in their talons and dropping them on a patch of savanna away from the original wildfire. The kites then pick off the escaping prey. Setting a new area ablaze allows that individual kite to feed in a space where there aren’t so many rival predators. Learn more at BirdNote.org.

Birds Berries and Germination Jan 05, 2022

Some plants have evolved fruits with edible flesh that attract birds. When birds swallow the fruit, they also ingest the seeds. They transport the seeds to new spots for the plants to take root. Birds’ digestive systems grind away the hard outer coating of the seed, making it more likely to germinate. Seeds in a bird’s droppings are pre-packaged in nutrient-rich fertilizer. Learn more at BirdNote.org.

Rachel Carson and the Veery Jan 04, 2022

Rachel Carson, author of Silent Spring, and her beloved friend Dorothy Freeman shared a love of nature… and especially of one particular bird: the Veery, a type of thrush. Plain looking as it is, the Veery has a particularly beautiful song. Learn more at BirdNote.org.

City Hawks Versus Country Hawks Jan 03, 2022

Resident Cooper’s Hawks that nest in the urban areas of Albuquerque, New Mexico, are thriving as the populations of doves, their prey, have exploded. The easy prey gives the urban birds a competitive advantage over hawks in more natural habitats, where prey is less concentrated. The soaring numbers of urban Cooper's Hawks could help preserve the genetic diversity of the species far into the future. Learn more at BirdNote.org.

Alpine Swifts Fly Nonstop Jan 02, 2022

How long can a bird fly without touching the earth? To find out, Swiss scientists attached sensors to Alpine Swifts. The sensors showed long periods when the swifts were gliding and not flapping their wings. Were the birds asleep? Scientists don’t know for sure. It could be that Alpine Swifts sleep during the summer breeding season — and don’t sleep at all during migration. But why do they stay aloft so long? Swifts can’t perch because they have very short legs. So if they can manage it, avoiding touching down makes perfect sense. Learn more at BirdNote.org.

A New Year Dawns Jan 01, 2022

Downy Woodpeckers Dec 31, 2021

Coast to coast, border to border, forest to feeder, the Downy Woodpecker goes about its business in 49 states. The smallest woodpecker in the United States, it turns up everywhere there are a few trees, except in the dry deserts of the Southwest and in Hawaii. Learn more at BirdNote.org.

Brown Pelicans - Conservation Success Dec 30, 2021

Brown Pelicans are a regular sight today along the Gulf of Mexico and our southern coastlines. But these birds have not always been so plentiful. They were hunted for their feathers and as pests by fishermen. The Migratory Bird Act of 1918 protected their recovery. But by 1970, pesticides were killing pelicans outright and thinning their eggshells. The 1972 Endangered Species Act has helped lead to a gradual comeback. Learn more at BirdNote.org.

Birds of Paradise Dec 29, 2021

It's morning on the island of New Guinea, and the lowland forests erupt with the crowing calls of Birds of Paradise. Male Raggiana Birds of Paradise perform elaborate displays to attract females, sometimes even hanging upside-down with their wings pointing upward. Forty-three species of Birds of Paradise are found on or near New Guinea. Learn more at BirdNote.org.

Bird Seed Dec 28, 2021

When buying seed for your feeders, it’s tempting to get the biggest, cheapest bag. But not all bird seed is the same. Figure out the nutritional value of the seeds and whether your local birds can actually eat them. Black-oil sunflower seeds provide good protein and fat. Other good seeds include white millet and nyjer thistle. Avoid red milo, a livestock grain. And clean your feeding station regularly to prevent the spread of disease. Learn more at BirdNote.org.

Freeway Hawks Dec 27, 2021

Driving the freeway or a narrow country road, you may glance up at a light pole where a large hawk sits in plain view. If it's brown and somewhat mottled, and its small head and short tail make it appear football-shaped, it's probably a Red-tailed Hawk. During winter, many Red-tailed Hawks move south, joining year-round residents. Learn more at BirdNote.org.

How Birds Become Red Dec 26, 2021

Most birds have the capacity to make red feathers, even those that lack red plumage. This discovery was revealed by scientists who studied Red-factor Canaries — a “hybrid” bird that is part canary, part Red Siskin, like this one. Both species have the “redness gene.” But Red-factor Canaries have a thousand times more red pigment in their skin. And why? Red-factor Canaries inherited the siskin’s “genetic switch” that turns on the redness gene in their skin. So just having the gene is not enough: if the genetic switch in the skin is turned off . . . no red feathers. Learn more at BirdNote.org.

Why Some Birds Sing in the Winter Dec 25, 2021

By late January, some resident birds, such as the Northern Mockingbird, are beginning their spring singing. When you step outside on a particularly sunny day this winter, a Fox Sparrow like the one pictured here may be warming up for the coming spring. And as far north as British Columbia, Pacific Wrens are singing in earnest by mid-February. So the singing season never entirely stops. Learn more at BirdNote.org.

Pigeon Flocks Follow the Leader Dec 24, 2021

The flocking movements of homing pigeons are governed by a pecking order. Higher-ranked birds have more influence over how the flock moves. Leading birds change directions first, and followers swiftly copy the leader's movements. And birds at the front of the flock tend to make the navigational decisions. In other words, the pigeons follow the leader. Or leaders. learn more at BirdNote.org.

Graylag Goose Dec 23, 2021

The goose of today’s farmyards was domesticated about 3,000 years ago from the Graylag Goose, the wild species found today throughout much of Europe and Asia. To ancient Egyptians, the goose symbolized the sun god Ra. Greeks linked the goose with Aphrodite, the goddess of love. And geese are prominently featured in the Shijing, the oldest existing collection of Chinese poetry. Learn more at BirdNote.org.

The Majestic Gyrfalcon Dec 22, 2021

Gyrfalcons are the largest falcons in the world, with a wingspan of almost four feet and weighing almost five pounds. The name “Gyrfalcon” derives from an Old Norse word for “spear.” During the summer, you’ll find Gyrfalcons on the tundra, where they feed on arctic birds. But in the winter, some will fly as far south as the northern U.S. Learn more at BirdNote.org.

How Birds Survived the Asteroid Dec 21, 2021

The asteroid that struck the Yucatán 66 million years ago wreaked worldwide ecological damage, spelling the end for most dinosaurs and destroying the world’s forests. Yet a few bird-like dinosaur groups made it through. Scientists believe that these groups were all ground-dwellers. Though some species could fly, a life on the ground would have been a key advantage in a world without forests. All modern birds evolved from these ancient creatures. Learn more at BirdNote.org.

Margaret Morse Nice and the Song Sparrow Dec 20, 2021

Few backyard birds in North America are more widespread than the Song Sparrow. But it was the study of this seemingly unremarkable bird that helped shape modern ornithology. In 1928, Margaret Morse Nice began carefully observing Song Sparrows near Columbus, Ohio, where she lived. For eight years, Nice banded and made detailed accounts of the birds' lives and behavior. The emphasis on bird behavior — and painstaking observation of living birds in the wild — helped shift the focus away from collection, description, and distribution. And it all started with that little brown bird with the melodious song. Learn more at BirdNote.org.

Not Just Any Nectar Will Do Dec 19, 2021

Hummingbirds such as this Buff-tailed Sicklebill specialize in nectar feeding. But other species of birds, less specialized to nectar, also visit flowers for a taste of the sweet stuff. The flowers they visit likely have a more open shape, with nectar more accessible to a non-specialist’s bill. The sugar they sample is probably different from what hummingbirds prefer. As flowering plants and birds co-evolved, each to benefit from the other, it seems likely that plants evolved the type of sugar best suited to the pollinators on hand. It's a win-win for all concerned. Learn more at BirdNote.org.

The Cardinal: A Southerner Moves North Dec 18, 2021

Holiday cards often feature gorgeous red cardinals against a snowy landscape. So it’s easy to assume the birds have always been a colorful presence in bleak Northern winters. But cardinals used to be Southern birds. By the second half of the 20th century, though, they were nesting as far north as Maine, the northern Midwest, and even southern Canada.

Spark Bird: Drew Lanham Takes Flight Dec 17, 2021

Acclaimed ornithologist and writer J. Drew Lanham’s obsession with birds began when he was a kid, when he wished to take flight alongside them. He tried out cardboard wings and an umbrella, trying to defeat gravity. He kept refining his designs and finding better jump-off spots. He eventually gave up on trying to fly, but he never stopped loving birds. Learn more at BirdNote.org.

Basalt as Shelter Dec 16, 2021

As the winter sun sinks over the Coulee Lakes, hundreds of Gray-crowned Rosy-Finches suddenly appear, an undulating cloud that swarms into the upper levels of the basalt cliffs. The finches nest high in the mountains in summer, and roam the countryside in large flocks in winter. Gray-crowned Rosy-Finches roost for the night in a colony of abandoned swallow nests on basalt cliffs. Learn more at BirdNote.org.

Bluebirds Close to Home Dec 15, 2021

Bluebirds can bring flashes of azure color and mellow songs to where you live. The best way to bring them close to home is with nest boxes. You’ll need an untreated wood box with a one-and-a-half inch hole five feet above the ground. Finding the right place for the nest box is important, too. Shrubs that bear small fruits can entice bluebirds. Find instructions for building an effective bluebird nest box at BirdNote.org.

Winter Brings Snow Buntings Dec 14, 2021

Snow Buntings begin their lives amid the harsh conditions of the high Arctic. They're prized winter visitors to the northern tier of states. Look for them along shorelines, in farmland, and open country - landscapes that mirror the Arctic tundra where they fledge their young. Snow Buntings face the prospect of a shrinking nesting range, as global climate change transforms far northern habitats. Learn more at BirdNote.org.

Razorbills Swim in Synchrony Dec 13, 2021

Razorbills, a cousin to the puffin, nest in colonies on cliffs. Before they lay eggs, Razorbills take part in two unique social behaviors. In one, the Razorbills swim round and round in a tight mass, then dive as one. Next, they surface with heads aligned and bills held open. In another behavior, dozens of birds swim in a line, then zig-zag in a synchronized pattern across the ocean’s surface. Learn more at BirdNote.org.

Just What Are Flamingos? Dec 12, 2021

Few birds are as distinctive as flamingos. Scientists once grouped flamingos with storks and ibises. But a study of flamingo DNA delivered a stunning surprise: their closest living relatives appear to be grebes. And an even bigger surprise: DNA indicates that flamingos and grebes share an ancestry with certain land birds, like doves. So flamingos evolved long legs and necks, just as herons and storks did. But they belong on a completely different branch of the tree of life. Learn more at BirdNote.org.

Following the Honeyguide Dec 11, 2021

The Greater Honeyguide's demanding call is not aimed at a member of its own species. Instead, the bird guides people in search of honey through the forest, directly to bee hives. The bird flies to a colony of bees living in a hollow tree. The human follower exposes the hive with an ax and takes much of the honeycomb. Then the honeyguide moves in to feast on bee larvae and beeswax. Learn more at BirdNote.org.

Crested Auklets Winter in the Bering Sea Dec 10, 2021

The Bering Sea in winter, framed as it is by Alaska and Siberia, is frigid, stormy, and dark. But remarkably, some birds seem right at home there. The Crested Auklet is one such bird. And they have some unique qualities. Crested Auklets bark like Chihuahuas. Also, these seabirds exude an odor of oranges from a chemical they produce that repels ticks. They nest in immense colonies on Bering Sea islands, and remain nearby through winter, in flocks of many thousands. The auklets present a superb natural spectacle - sight, sound, and smell!

The Wonderchicken! Dec 09, 2021

In 2018, paleontologist Daniel Field took a closer look at specimens from an amateur fossil collector. His team used micro-CT scanning, kind of like a high-energy CAT scan, to visualize the encased fossils. They were amazed to find a tiny bird skull: the earliest known fossil record of a modern bird. The skull looks chicken-like in the front and duck-like in the back. The bird may have looked and behaved like a modern shorebird. Learn more at BirdNote.org.

Morning in Oaxaca Dec 08, 2021

A winter morning in Oaxaca, Mexico—a great time to visit old friends who spent the summer in the United States. Yellow-rumped Warblers and Western Tanagers—northern summer-nesters that winter in western Mexico—mingle with resident Berylline Hummingbirds, Gray Silky-Flycatchers, and this Crescent-chested Warbler.

Why Penguin Feathers Don't Freeze Dec 07, 2021

Gentoo Penguins live in the frigid waters of the Atlantic. Only recently have scientists begun to unravel why penguin feathers don’t freeze. An electron microscope revealed tiny pores on the feathers that trap air, making the surface water repellent. This feature, plus a special coating oil from the preen gland, prevents water build-up and delays freezing. Engineers could attempt to apply these principles to prevent icing on plane wings.

Birds on a Cold Night Dec 06, 2021

During December, birds spend the long, cold nights in a protected place, sheltered from rain and safe from nighttime predators. Small forest birds, such as nuthatches and creepers, may spend the night huddled together in tree cavities. Birds like this male Mallard fluff up their feathers for insulation, hunker down over their legs and feet, and turn their heads around to poke their beaks under their shoulder feathers.

Recording the Araripe Manakin, With Gerrit Vyn Dec 05, 2021

Near the city of Crato in northeastern Brazil lives a critically endangered little bird — the Araripe Manakin. It’s a little larger than a sparrow, it’s beautiful, and it lives on the slopes of a very small area in the Araripe Plateau. And because the Araripe Manakin wasn’t discovered until the late 1990s, it’s relatively unstudied. Gerrit Vyn of the Cornell Lab of Ornithology is on a mission to capture a “clean” recording of the Araripe Manakin — one without human-generated noise in the background. Will he succeed? Learn more at BirdNote.org.

Searching for the Araripe Manakin, With Gerrit Vyn Dec 04, 2021

Gerrit Vyn is a sound recordist for the Cornell Lab of Ornithology. He recently traveled to northeastern Brazil’s Araripe Plateau in search of the Araripe Manakin, a beautiful white bird with dark wing-tips and tail-feathers — and a deep red hood. The Araripe Manakin is critically endangered, in part because of its limited range. But, as Gerrit observes, human activity also threatens the bird’s survival. Learn more at BirdNote.org.

BirdNoir - The Mystery of the Blue Bird Dec 03, 2021

In this episode of BirdNoir, Michael Stein — Private Eye — gets a call from a friend, Danny, who wants to know why the bluest bird he’s ever seen has vanished. But there are many birds that are blue besides the true bluebirds (which belong to the thrush family). To solve the mystery, the detective needs to know the right questions to ask Danny, finding the relevant information to identify the bird and figure out what happened. Learn more at BirdNote.org.

Encounter with a Cassowary Dec 02, 2021

In a tropical woodland in eastern Australia, you glimpse a Southern Cassowary, a huge flightless bird that must rate as the most prehistoric looking of all birds. Cassowaries are capable of making remarkable sounds, including the lowest known bird call in the world, barely audible to the human ear! Learn more about the Southern Cassowary at BirdNote.org.

Spark Bird: A Blackburnian Warbler’s Journey Dec 01, 2021

Justine Bowe fell in love with birds when she was a kid, on a hike with her dad when she saw the fiery colors of a Blackburnian Warbler. Justine now manages the Bird Friendly Coffee program at the Smithsonian Institute's Migratory Bird Center, working with coffee farmers to preserve habitat for birds that migrate to Central and South America. In Colombia, she got to see Blackburnian Warblers spending winter on bird-friendly farms. Learn more at BirdNote.org.

Common Redpoll Nov 30, 2021

The tiny Common Redpoll, one of the smallest members of the finch family, weighs only as much as four pennies, yet it survives the cold and darkness of winter in the far North. Most birds depart in autumn to warmer climes. But redpolls feed on birch and alder seeds that are available throughout the winter, no matter how deep the snow. This little bird typically eats 40% of its body weight in seeds every day to keep itself alive. Redpolls are survivors. Learn more at BirdNote.org.

Welcoming Back Winter Birds Nov 29, 2021

Although we may think of autumn as the end of the growing season, a sort of winding down in the natural world, for birds it’s as much a season of renewal as the spring. In the colder months, we welcome back our winter birds — juncos, swans, and more — which spent the summer in their breeding territories to the north. Offering the right kind of food and environment in the winter months can attract these migrants to your yard! Learn more at BirdNote.org.

Ivory Gull and Conservation Nov 28, 2021

Polar Bears symbolize the icy landscapes of the far north like no other animal. The bear's way of life — its very survival — is inseparable from the Arctic pack-ice. Less familiar is a remarkable bird that shares with the Polar Bear this vital link to ice: this Ivory Gull. The gulls feed on small fish and other marine life, but also scavenge carcasses, including those left by Polar Bears. Global warming has brought increasing change to the world of ice-dependent species such as the Ivory Gull and Polar Bear. Learn more at BirdNote.org.

A Blizzard of Snow Geese Nov 27, 2021

An immense field appears to be covered with snow, blanketed in white. But a closer look reveals more than 10,000 Snow Geese. Snow Geese nest on Wrangel Island, in the Chukchi Sea off northern Siberia. Don't miss the amazing video by Barbara Galatti! Learn more at BirdNote.org.

Why Birds Eat Snow Nov 26, 2021

In the depths of winter, when open water is frozen over, it can be challenging for birds to stay hydrated. Some birds eat the frozen water all around them. Cedar Waxwings catch snowflakes in mid-air. Black-capped Chickadees drink from dripping icicles. Plenty of other birds scoop up fresh, powdery snow and eat it. It could be worth the calories to melt the snow when searching for liquid water could expose them to predators. Learn more at BirdNote.org.

How Much Do Birds Eat? Nov 25, 2021

There used to be a saying about somebody who doesn’t eat much — “she eats like a bird.” But how much does a bird typically eat? As a rule of thumb, the smaller the bird, the more food it needs relative to its weight. A Cooper’s Hawk, a medium-sized bird, eats around 12% of its weight per day. For a human weighing 150 pounds, that’s 18 pounds of chow, or roughly six extra-large pizzas. And that perky little chickadee at your feeder eats the equivalent of 35% of its weight. You, as a 150-pound chickadee, will be munching 600 granola bars a day. And a hummingbird drinks about 100% of its body weight per day. That means you’ll be sipping 17½ gallons of milk.

In Winter, Puffins Lead Very Different Lives Nov 24, 2021

Every summer, puffins — like this Horned Puffin — grow blazingly colorful layers over the bases of their huge beaks. But in the winter, puffins lead very different lives, and they shed their bright ornamentation. Puffins in winter are largely solitary — and silent. They spend about seven months alone at sea, before returning once again to their colonies to breed. Learn more at BirdNote.org.

Singing Under Streetlights Nov 23, 2021

Some birds have always called nocturnally, but other species are relative newcomers to the nighttime music scene, specifically in urban areas. Birds such as American Robins often sing well into the night. Scientists are studying what environmental cues might lead to this behavior. While artificial light could be a factor, recent studies suggest that some birds may be avoiding daytime city noise by singing nocturnally. Learn more at BirdNote.org.

Aplomado Falcon Nov 22, 2021

Aplomado Falcons were once widespread residents of the American Southwest, but by the 1950s, they'd disappeared entirely from the region. Loss of habitat, loss of prey, and pesticides all played a role. But in the 1980s, a group called The Peregrine Fund began breeding captive Aplomado Falcons. Over the next 25 years, 1,500 fledglings were set free in South Texas. At the same time, conservation pacts with private landowners provided more than two million acres of habitat. Learn more at BirdNote.org.

Birds of Prey and Nesting Territories Nov 21, 2021

Red-tailed Hawks typically have a nesting territory of about a half-mile to a full square mile, depending on how much food there is. Bald Eagles’ nesting territories range from 2½ square miles to as much as 15 square miles, for the same reason. But the Gyrfalcons in Finland and Scandinavia really need their space! Learn more at BirdNote.org.

Swans Come Calling Nov 20, 2021

Trumpeter Swans land in a plowed field to forage for remnant potatoes, grain, and other waste crops. This swan is among the largest of all waterfowl; the Tundra Swan is somewhat smaller. These swans migrate in family groups each fall from nesting sites in Canada and Alaska. Learn more about these swans, and view a map to the Skagit Flats of Washington where you can see them. When you go, please be courteous, and if you stop, pull completely off the roadway. Always respect private property.

Seabirds, Trees and Coral Nov 19, 2021

Palmyra Atoll is a ring-shaped island encircling a lagoon in the South Pacific. The atoll lost many native trees due to U.S. military activity during World War II. Conservationists have worked to restore the ecosystem. Seabirds such as Black Noddies and Red-footed Boobies nest in the island’s rainforest. Their guano enriches the soil, and the soil’s nutrients help support the coral ecosystem that provides fish for the birds. Learn more at BirdNote.org.

To Mob or Not to Mob Nov 18, 2021

When a bird of prey flies over, a flock of crows may dive-bomb the predator and give it a noisy escort out of town. An Eastern Kingbird, like this one, will clamp its feet onto the back of a hawk to send it packing. How do they know which birds to chase off and which to ignore? By genetic wiring, or instinct, but also learning. By watching their parents in the act of mobbing, youngsters gain critical knowledge that may save their own skin. Learn more at BirdNote.org.

Spark Bird: Nick Belardes and the Vermilion Flycatcher Nov 17, 2021

Author Nick Belardes was walking at a park near his home in San Luis Obispo, California, when he saw a man who seemed in tune with birds. Belardes asked him what the coolest bird around was, and the man replied Vermilion Flycatcher. Belardes and his wife soon went out looking for the ruby-like bird, finally spotting it through rain and mist. He remembers that sighting as a turning point that drew him deeper into the world of birds. Learn more at BirdNote.org.

The Gorgeous Gadwall Nov 16, 2021

When you first glimpse a male Gadwall, you might think you're looking at a female Mallard. But take a closer look, and you'll see plumage as richly and subtly colored as an English gentleman's tweed jacket. For a closer look, click Enlarge under the photo. The Gadwall now nests all across the northern US and into Canada. You can probably see one of these handsome birds on a pond or in a marsh near you. Some may even breed in your neighborhood.

Catching Insects Nov 15, 2021

Birds that depend on flies for food have many creative ways of catching their prey. Swallows execute sharp turns and quick changes of speed. Bluebirds watch from a perch, pouncing when the time is right. A Chuck-will’s-widow flies with its scoop-like mouth wide open, engulfing moths and other insects. A Merlin snares dragonflies in its talons. Hummingbirds dart into swarms of midges. Learn more at BirdNote.org.

Western Hummingbirds, East Nov 14, 2021

Not long ago, the only hummingbird that someone living in the eastern United States and Canada could hope to see was the Ruby-throated Hummingbird. But things have changed. Today, more and more hummingbird species — such as this Broad-tailed Hummingbird — have been discovered beyond their “normal” ranges. Why is this colorful explosion happening now? Climate change is one possible factor. So are shifts in migration routes. Or it could just be that more people are on the lookout for these relative newcomers. Learn more at BirdNote.org.

Habitat Defined Nov 13, 2021

When you think of habitat, think of home. For a jay that lives in the forest, the forest is its habitat – where it finds food, water, shelter, and the company of other jays. Or it might live in your back yard or the bank parking lot down the street. Some birds live in different habitats at different times of year. Many sandpipers summer on the Arctic tundra, but during the rest of the year, they live on coastal tide flats. Learn more at BirdNote.org.

A Pocket Guide to Pigeon Watching Nov 12, 2021

Illustrator and science writer Rosemary Mosco is the author of the new book, A Pocket Guide to Pigeon Watching. The book explores humanity’s long relationship with pigeons, from domestication thousands of years ago to fancy pigeon breeding in recent centuries. Rosemary's book not only breaks down the variations to look for in feral city pigeons, but also some of the most bizarre fancy breeds. Learn more at BirdNote.org.

How Terns Read the Water Nov 11, 2021

Like an expert angler, a tern can read the surface of the water to find where to catch its next fish. Scientists piloted a drone to track the flight paths of terns on the hunt. The terns sought out turbulent water. A vortex formed by colliding currents traps fish near the surface, where terns can snap them up. Terns fly toward bubbly upwellings to see if the rising water brings prey animals along with it. Learn more at BirdNote.org.

Starling Mimicry Nov 10, 2021

The searing cry of a Red-tailed Hawk pierces the air. The distinctive scream is coming from a tree nearby. But when you scan the tree for the form of a hawk, you see only a small, speckled, black bird. You’ve been fooled. It’s a starling giving voice to the hawk’s cry. The European Starling — the continent’s most abundant non-native bird — is an accomplished mimic. Starlings are especially astute imitators of bird sounds that have a whistled feel — like the sound of a Killdeer or quail. They can duplicate a car alarm or phone ring, too. Learn more at BirdNote.org.

Bird Brains in a New Light Nov 09, 2021

Many birds are remarkably clever. New findings help reveal how they can be so smart. In mammals, intelligence is seated in the neocortex, which has neurons arranged in layers and columns. Birds lack a neocortex and were thought to have a forebrain composed of simple clusters of neurons. Recent research indicates that a part of the bird forebrain, the dorsal ventricular ridge, has neurons layed out similarly to those in the mammalian neocortex. Learn more at BirdNote.org.

Birds in the Winter Garden Nov 08, 2021

Put your winter garden to work as a haven for birds. Leaves and brush left to compost provide foraging and roosting places, smother this year’s weeds, and feed next spring’s plant growth. Watch for juncos and towhees in the leaf litter, and wrens in the brush. Maybe even a Song Sparrow, like this one! With a little planning, your garden can be a haven for birds year round. Learn more at BirdNote.org.

Fancy Fruit-doves in the South Pacific Nov 07, 2021

Fruit-doves are forest-dwelling doves of the South Pacific found on island groups like the Philippines and New Guinea. There are 54 species of fruit-doves, most about the size of a Mourning Dove or smaller, and they do indeed eat fruit. The combinations of bold colors in fruit-doves are unmatched by any other group of birds. Learn more at BirdNote.org.

Common Mergansers Pushed by the Ice Nov 06, 2021

Around this time of year, Common Mergansers cross the US-Canadian border on their way to wintering grounds in the Lower 48. But how do they know when to go? Ducks are well insulated against frigid winter temperatures, but mergansers can find their fishy prey only by diving below the surface of open water. So they’re doing just fine, resting and feeding in southern Canada, until a thin veneer of ice forms on their lake, signaling the time has arrived to head south! Learn more at BirdNote.org.
