Greater Racket-tailed Drongo Dec 18, 2014

Show notes

Tweet of the Day is the voice of birds and our relationship with them, from around the world. Liz Bonnin presents the greater racket-tailed drongo of South-East Asia. Across a clearing in a Malaysian forest flies a dark bird, seemingly chased by two equally dark butterflies. Those butterflies in hot pursuit aren't insects at all; they are the webbed tips of the greater racket-tailed drongo's excessively long wiry outer-tail feathers, which from a distance look like separate creatures as it flies. Glossy blue-black birds which live in wooded country and are great insect catchers, hawking after them in mid-air before returning to a perch. They're bold too and won't hesitate to harry and chase much larger birds than themselves, including, birds of prey. Like other drongos the greater racquet-tailed drongo has an extensive but not very musical repertoire which includes the sounds of other birds it meets, when it joins mixed feeding flocks, and can imitate the call of a hawk to alarm the hawk's victims and so steal food from them while they are distracted by the call: an ingenious tactic, which few other birds have learned.

Saddleback Dec 17, 2014

Show notes

Tweet of the Day is the voice of birds and our relationship with them, from around the world. Liz Bonnin presents the formerly widespread saddleback of New Zealand. It's loud, piping and whistling calls once resounded throughout New Zealand's forests, but now the saddleback is heard only on smaller offshore islands. This is a bird in exile. About the size of a European blackbird, saddlebacks are predominantly black with a rust-coloured saddle-shaped patch on their backs. In Maori culture this mark came from the demi-God Maui who, after trying to catch the sun, asked the saddleback to fetch water. The bird refused, so hot-handed Maui grabbed it and left a scorch mark on the bird's back. As well as this chestnut saddle, the bird has two bright red wattles at the base of its beak which it can dilate when it displays. It also has an extensive vocabulary and one of its calls has earned it the Maori name –"Ti-e-ke".

Blue Manakin Dec 16, 2014

Show notes

Tweet of the Day is the voice of birds and our relationship with them, from around the world. Liz Bonnin presents the advancing, leaping and queuing male blue manakin of Brazil. Male blue manakins are small, blue and black birds with scarlet caps. They live in the forests of south-east Brazil and neighbouring areas of Argentina and Paraguay. Whilst their plumage is eye-catching, their mating display is one of the strangest of any bird. A dominant male Blue Manakin enlists the support of one or more subordinate males. Calling loudly, all the males sidle along a branch towards the female, taking turns to leap into the air and then fly back down and take their place at the back of the queue. This sequence of advancing, leaping and queuing occurs at a frenetic pace, until, without warning, the dominant male calls time on this avian dance-off, with a piercing screech.

Hawaiian Goose (Nene) Dec 15, 2014

Show notes

Tweet of the Day is the voice of birds and our relationship with them, from around the world. Liz Bonnin presents the Nene, or the endemic and rare Hawaiian goose. Visit a Wildfowl and Wetland Trust centre in the UK and it is likely you'll be mobbed by the nasal calls of one of the world's rarest birds, the Hawaiian Goose or "Ne-Ne". In the late 18th century there were around 25,000 of these neat attractive geese, with ochre cheeks and black-heads, on the Hawaiian Islands. But by the early 1950s, due to development and introduced predators, a mere 30 or so remained. A few of these remaining Nene's were taken to Slimbridge, home of Peter Scott's Wildfowl Trust as part of a captive breeding programme. They bred successfully and now many generations of geese produced there have been returned to their native islands. Their future is still precarious in the wild, but as the state bird of Hawaii the Nene's outlook is more secure today than for the last seventy years.

Morepork Dec 12, 2014

Show notes

Tweet of the Day is the voice of birds and our relationship with them, from around the world. Liz Bonnin presents the morepork or Ru-Ru, New Zealand's only surviving native owl. Strange double notes in the forests of New Zealand were once thought to be cries from the Underworld. But these calls are most likely to be that of a morepork calling. Its familiar call earned it the alternative Maori name of "ruru". Largely nocturnal, it has brown, streaky feathers and large bright yellow eyes which are well adapted for almost silent night hunting forays for large insects, spiders, small birds and mammals. In Maori mythology, moreporks, or "ruru" are spiritual birds, and can represent the ancestral spirit of a family, taking the form of a woman known as "Hine-Ruru" or "owl woman" who acts as a guardian, protecting and advising the family members.

Marabou Stork Dec 11, 2014

Show notes

Tweet of the Day is the voice of birds and our relationship with them, from around the world. Liz Bonnin presents the gaunt undertaker-looking marabou stork in Africa. It is not very scientific to describe a bird as ugly, but the marabou stork would not win any prizes for beauty or elegance. This bulky stork, with a funereal air, has a fleshy inflatable sac under its throat which conspicuously wobbles as it probes African rubbish dumps for carrion. Seemingly more at home amongst the melee of vultures and jackals squabbling over a carcass, it is known in some areas as the undertaker bird. But, in the air the marabou stork is an elegant sight. It has one of the largest wingspans of any bird, up to 3 metres across. Soaring effortlessly on these broad wings the storks scan the sub-Saharan landscape for food. Marabou storks are doing well, thanks to our throwaway society and they've learned to connect people with rubbish – a salutary association one might say.

Northern Jacana Dec 10, 2014

Show notes

Tweet of the Day is the voice of birds and our relationship with them, from around the world. Liz Bonnin presents the northern jacana at home in Central American wetlands. A cross between a coot and a plover, northern Jacanas are found in swamps in Central America and Mexico. They're long legged birds with a black head and neck, and a chestnut body with yellow highlights. And, northern jacanas are polyandrous; the females have more than one partner. Males build platforms of floating vegetation and attract females by calling or posturing. If a female mates with a male, he may use his platform as a nest for her eggs. The female doesn't care for the eggs, but goes in search of up to three other mates. The result is that a single female may have several males raising different clutches of eggs for her and each clutch may contain the eggs of more than one male!

Black-chinned Hummingbird Dec 09, 2014

Show notes

Tweet of the Day is the voice of birds and our relationship with them, from around the world. Liz Bonnin presents the North American black chinned hummingbird. What seems to be a large green beetle is flying erratically across a Los Angeles garden: suddenly, it hovers in mid-air to probe a flower bloom; this is a black-chinned hummingbird. Although often thought of as exclusively tropical, a few species of hummingbirds occur widely in North America and in the west; the Black-chinned hummingbird is the most widespread of all. Both sexes are glittering emerald above: the male's black throat is bordered with a flash of metallic purple, which catches the sun. Black-chinned "hummers" are minute, weighing in at just over 3 grams. But they are pugnacious featherweights seeing off rival males during intimidation flights with shrill squeals, whilst remarkably beating their wings around 80 times a second. They'll also readily come to artificial sugar-feeders put out by householders to attract these flying jewels to their gardens.

Red-crowned Crane Dec 08, 2014

Show notes

Tweet of the Day is the voice of birds and our relationship with them, from around the world. Liz Bonnin presents the red-crowned crane from Japan and Asia. Backlit by a Japanese winter sun, huge black and white birds dance for an audience. Their plumage mirrors the dazzling snow and dark tree-trunks. The only spots of colour are crimson - the caps of these Red-crowned Cranes. Red-crowned Cranes breed only in far-eastern Russia. Tall, majestic and very vocal, red-crowned cranes gather in groups to reinforce pair-bonds, by leaping into the air and fluttering their 2.5 metre wings, sometimes holding sticks or twigs in their long bills. During winter months, the cranes are fed with grain, and receive a stream of captivated visitors. In front of a wall of clicking camera shutters, the cranes perform their elaborate dance, to delight their captivated audience.

Brown Thrasher Dec 05, 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 brown thrasher, usually seen in North America. Brown thrashers are related to mockingbirds that breed across most of eastern and central North America. They're famous for their vast repertoire which can include over 1000 song types. They spend much of their time skulking in dense shrubs at woodland edges and in parks and gardens. They're russet on top, white below and heavily streaked like a large thrush but with much longer tails and stout curved bills. Their name comes from the noisy thrashing sound they make as they search the leaf litter for food. Normally, brown thrashers are short distance migrants within North America but in 1966, in November of that year, in Dorset, birdwatchers almost dropped their binoculars in disbelief when they heard the call of a brown thrasher coming from a coastal thicket. It remained here until February 1967 and is the only British record.
