Purple Martin Nov 20, 2014

Show notes

Tweet of the Day is the voice of birds and our relationship with them, from around the world. Chris Packham presents the purple martin from eastern North America. Every spring, across the land from Chicago to St Louis, you can hear couples squabbling over the best real estate. But these aren't human house-buyers, they're purple martins. Purple Martins are the largest North American swallow, glossy blue-black rather than purple and much chunkier than the well-known barn swallow. They spend the winter in insect-rich places in South America and return to their North American breeding colonies each spring. In the west, they nest in holes in trees or even in giant saguaro cacti, but in the east where they're much more common, they almost exclusively rely on people to provide them with nest-sites. Visit almost any city, town or homestead and you'll see multi-story nest-boxes, the home of a score of purple martin families. Around 1 million people are thought to erect housing each year. Their human landlords take a personal pride in their martin colonies, listening each spring for those first pebbly calls which are a sign that their protégés have made it back from the tropics, once again.

Asian Crested Ibis Nov 19, 2014

Show notes

Tweet of the Day is the voice of birds and our relationship with them, from around the world. Chris Packham presents the rare Asian crested Ibis formerly common in Japan and China. The crested ibis is mainly white with a shaggy white crest and a red face; but in the breeding season its plumage is tinged with ash-grey. Under its wings is a subtle peach tone, a colour known in Japan as toki-iro. Unfortunately its beauty hasn't saved the crested ibis from persecution in Japan, China or Siberia where it used to breed. It was thought to be extinct in China, until seven birds were found in 1981. In 2003 the crested ibis became extinct in the wild in Japan. Now, crested ibis are conservation symbols in the Far East. They are strictly protected in China where they are being reintroduced to increase the small wild population. In Japan the first wild Japanese crested ibis chick flew from its nest in 2012.

Rhinoceros Auklet Nov 18, 2014

Show notes

Tweet of the Day is the voice of birds and our relationship with them, from around the world. Chris Packham presents the rhinoceros auklet found around the North American western seaboard. Rhinoceros auklets are auks. They look very different to their relatives the puffins or guillemots. They're dark grey-ish brown birds, and in the breeding season both male and female have flowing white plumes above their eyes and behind their orange bills. It is the white vertical plate at the base of its bill which has inspired the birds' common names of "horn-billed puffins" or "unicorn puffins". This horn is only grown in the breeding season; the birds shed it in autumn when they head out to sea. Rhinoceros auklets in burrows or cavities in grassy places or on forest floors: most colonies are small, but some contain a hundred thousand birds which produce a soothing chorus of mooing and grunting sounds, strange to hear in the blackness of a coastal wood.

Arabian Babbler Nov 17, 2014

Show notes

Tweet of the Day is the voice of birds and our relationship with them, from around the world. Chris Packham presents the Arabian babbler of a Yemeni Desert. Arabian babblers could almost be described as feathered meerkats. They're sociable, charismatic and always on the alert. These energetic and curious birds are found around the Arabian peninsula and in Egypt, often in dry scrubby places. They have long tails, curved bills and a bounding gait, and their sandy plumage is superb camouflage against the parched ground where they roam in search of insects and seeds. If on their travels, a group of babblers discovers a snake they will mob it with loud shrieks, raising their wings and calling to each other until they see it off. Arabian babblers don't use their social skills just to chase away predators. They spend all their time in groups of usually four to six adult birds and in these groups their relationships are fluid. They are also co-operative breeders and help each other to rear their chicks, a communal way of life that helps to forge bonds between these very vocal birds.

Bell Miner Nov 14, 2014

Show notes

Tweet of the Day is the voice of birds and our relationship with them, from around the world.

Chris Packham presents the bell miner of eastern Australia. The sound of a tiny hammer striking a musical anvil in a grove of gum trees signifies that bell miners are in search of sugar. More often heard than seen the bell miner is a smallish olive-green bird with a short yellow bill, with a small orange patch behind the eye. It belongs to a large family of birds known as honeyeaters because many have a sweet tooth and use their long bills to probe flowers for nectar. But the bell miner gets its sugar hit in other ways. Roving in sociable flocks, bell miners scour eucalyptus leaves for tiny bugs called psyllids who produce a protective waxy dome. Bell miners feed on these sweet tasting shelters. Some scientists suggest that Bell Miners actively farm these insects by avoiding over-exploiting of the psyllid colonies, allowing the insects numbers to recover before the birds' next visit. So dependent are they on these psyllids bugs that Bell Miners numbers can often fluctuate in association with any boom-and-bust changes in psyllid population.

Plumbeous Antbird Nov 13, 2014

Show notes

Tweet of the Day is the voice of birds and our relationship with them, from around the world.

Chris Packham presents the Plumbeous antbird in a Bolivian rainforest. When army ants go on the march in the Bolivian rainforest, they attract a huge retinue of followers; often heard but rarely seen. These include Antbirds. The Plumbeous Antbird is a lead-coloured bird; the males have a patch of blue skin around their eyes, whilst the females are bright russet below. Like other antbirds they are supreme skulkers, hiding under curtains of dense foliage and only betraying themselves by their calls and song, a particularly fluty call. But you'd think that with a name like antbirds, their diet is easily diagnosed, but surprisingly antbirds rarely eat ants. Instead, most species shadow the columns of army ants which often change nest-sites or raid other ant colonies. As the ants march across the forest floor, they flush insects and other invertebrates which are quickly snapped by the attendant antbirds.

Common Indian Cuckoo Nov 12, 2014

Show notes

Tweet of the Day is the voice of birds and our relationship with them, from around the world. Chris Packham presents the Indian cuckoo found across much of South East Asia. A bird singing "crossword puzzle" - "crossword puzzle" over the woods is an Indian Cuckoo, a shy and slender bird, grey above and barred black and white below. These features are similar to those of a small hawk and when a cuckoo flies across a woodland glade, it's often mobbed by other birds. They're right to sense danger. Indian cuckoos are brood parasites and the females lay their eggs in the nests of other species including drongos, magpies and shrikes. The Indian cuckoo's song is well-known in the Indian sub-Continent and has been interpreted in different ways. As well as "crossword puzzle " some think it's saying "one more bottle" or "orange pekoe". And in the Kangra valley in northern India, the call is said to be the soul of a dead shepherd asking "... where is my sheep? Where is my sheep?".

Southern Cassowary Nov 11, 2014

Show notes

Tweet of the Day is the voice of birds and our relationship with them, from around the world. Chris Packham presents the roaring southern cassowary of Australia's Queensland. The territorial roaring calls of the world's second heaviest bird, the cassowary are odd enough, but it still won't prepare you for your first sighting of these extraordinary birds. Reaching a height of over 1.5 metres, they have thick legs armed with ferocious claws, blue – skinned faces and scarlet dangling neck- wattles. These are striking enough but it is the large horn, or casque, looking like a blunt shark's fin on the bird's head that really stands out. It's earned this giant its common name - cassowary comes from the Papuan for "horned head". Such a primitive looking creature seems out of place in the modern world and although the southern cassowary occurs widely in New Guinea, it's still hunted for food there. Cassowaries can kill dogs and injure people with their stout claws, but the bird usually comes off worst in confrontations.

Vegetarian Tree Finch Nov 10, 2014

Show notes

Tweet of the Day is the voice of birds and our relationship with them, from around the world. Chris Packham presents the vegetarian tree finch on the Galapagos Islands. These streaky sparrow-like birds found on the Galapagos Islands may look rather plain, but belong to the evolutionary elite, having attracted the attention of Charles Darwin on his visit there in 1835. Darwin noticed that the fourteen or so species of finches, which he concluded were derived from a common ancestor on this isolate archipelago, had evolved bills adapted to the type of food available. The Vegetarian finch has a bill rather like a parrot's, with thick curved mandibles and a biting tip which also allows it to manipulate seeds, similar to a parrot or budgie. Vegetarian finches are especially fond of the sugar-rich twigs of certain shrubs and are use the biting tip of their bills to strip off the bark to reach the softer sweeter tissues beneath: a niche that other finches on Galapagos haven't exploited yet.

Blue Jay Nov 07, 2014

Show notes

Tweet of the Day is the voice of birds and our relationship with them, from around the world. Chris Packham presents the North American blue jay. The loud warning screams of blue jays are just part of their extensive vocabulary. These birds are intelligent mimics. Blue jays are neat handsome birds; lavender-blue above and greyish below with a perky blue crest, black collar and white face. But the blue jay is not blue, but black. Its feather barbs contain a dark layer of melanin pigment; the blue we see is caused by light scattering through modified cells on the surface of the feather barbs and reflected back as blue. Common over much of eastern and central North America, blue jays will move in loose flocks to take advantage of autumnal tree mast. A single blue jay can collect and bury thousands of beechnuts, hickory nuts and acorns (in a behaviour known as caching) returning later in the year to retrieve these buried nuts. Any they fail to find, assist in the natural regeneration of native woodlands.
