House Crow Oct 23, 2014

Show notes

Tweet of the Day is the voice of birds and our relationship with them, from around the world. Miranda Krestovnikoff presents the house crow, native of southern Asia. Leggier and longer-billed than the slightly larger European carrion crow and having a charcoal grey bib and collar and raucous call, these are common birds in towns and villages from Iran through India to Thailand. As scavengers they eat almost anything, which is how they've come to live alongside us. We provide water as well as food and have introduced the birds into areas of the Middle East and Africa. Although they don't fly long distances, the crows often hop aboard ships and arrive in foreign ports. Ship-assisted house crows have the potential to spread around the globe, a beautiful example of avian exploitation of human activity.

Red-billed Quelea Oct 22, 2014

Tweet of the Day is the voice of birds and our relationship with them, from around the world. Miranda Krestovnikoff presents the World's most numerous bird; red billed quelea. Red-billed queleas are the most numerous birds in the world and as part of the weaverbird family sound and look like small neat sparrows. Their ability to adapt to local conditions and travel for food allows large populations of fast-breeding queleas to build up. The statistics are mind-boggling. Some flocks of red-billed quelea can comprise millions of birds which may take hours to fly past. There are probably between one and a half and ten billion birds in Africa. They breed in vast colonies; one colony in Nigeria covered one hundred and ten hectares and contained thirty one million nests.

Satin Bowerbird Oct 21, 2014

Show notes

Tweet of the Day is the voice of birds and our relationship with them, from around the world. Miranda Krestovnikoff presents Australia's satin bowerbird. Then male is a blackish looking bird with bright purple eyes, whose plumage diffracts the light to produce an indigo sheen with a metallic lustre. He builds a U-shaped bower of sticks on the forest floor into which he hopes to lure a female. But brown twigs on a brown woodland floor aren't very eye-catching, so he jazzes up the scene with an array of objects from berries and bottle-tops to clothes-pegs and even ballpoint pens. All have one thing in common: they are blue. The male dances around his bower to attract the greenish females: often holding something blue to impress her. As he poses, he calls enticingly to advertise his prowess. Once she's made her choice, she will leave to build her nest and rear her young alone.

Montezuma Oropendola Oct 20, 2014

Show notes

Tweet of the Day is the voice of birds and our relationship with them, from around the world. Miranda Krestovnikoff presents the Panamanian Montezuma oropendola. In a clearing in the humid rainforest in Panama a tall tree appears to be draped in hanging baskets. These are the nests of a New World blackbird, Montezuma oropendola. The male produces an ecstatic bubbling liquid call as he displays to females, reaching a crescendo whilst bowing downwards from his perch, spreading his wings and raising his tail. They weave long tubular basket-like nests from plant fibres, which they suspend in clusters from tall trees. Colonies can contain up to one hundred and seventy nests, but more usually number about thirty.

Echo Parakeet Oct 17, 2014

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

Miranda Krestovnikoff presents the echo parakeet found only in Mauritius, a bird which has brushed extinction by its wingtips. This once familiar bird of the island of Mauritius will only nest in large trees with suitable holes, few of which remain after widespread deforestation on the island. A close relative of the more adaptable ring necked parakeet found now across southern Britain where it's been introduced, by the 1980's the wild population of echo parakeets numbered around ten birds. Threatened with extinction in the wild, captive breeding and successful releases into the wild have stabilised the population to about three hundred birds.

Crested Lark Oct 16, 2014

Show notes

Tweet of the Day is the voice of birds and our relationship with them, from around the world. Miranda Krestovnikoff presents the crested lark found from Europe across to China. The west coast of Europe is one edge of the huge range of the crested lark. Much like many larks it is a streaky brown bird but supports, as its name suggests a prominent crest of feathers on its head. Its song is delivered in a display flight over its territory as a pleasant series of liquid notes. Unlike skylarks which are rural birds, crested larks often nest in dry open places on the edge of built-up areas. Its undistinguished appearance and behaviour were cited by Francis of Assisi as signs of humility and he observed that like a humble friar, "it goes willingly along the wayside and finds a grain of corn for itself".

Galapagos Mockingbird Oct 15, 2014

Show notes

Tweet of the Day is the voice of birds and our relationship with them, from around the world. Miranda Krestovnikoff presents a bird which intrigued Darwin, the Galapagos mockingbird. There are four species of Mockingbird in the Galapagos islands, which probably all descended from a single migrant ancestor and then subsequently evolved different adaptations to life on their separate island clusters, hence their fascination for Charles Darwin. The most widespread is the resourceful Galapagos Mockingbird. Unlike other mockingbirds which feed on nectar and seeds, the Galapagos mockingbird has adapted to its island life to steal and break into seabird eggs and even attack and kill young nestlings. They'll also ride on the backs of land iguanas to feed on ticks deep within the reptiles' skin and will boldly approach tourists for foot. They aptly demonstrate the theory of the "survival of the fittest".

Common Hawk Cuckoo Oct 14, 2014

Show notes

Tweet of the Day is the voice of birds and our relationship with them, from around the world. Miranda Krestovnikoff presents the common hawk cuckoo from the Bengal region. The repetitive call of the common hawk-cuckoo, otherwise known as the brain-fever bird, is one of the typical sounds of rural India and on into the foothills of the Himalayas. Its name partly derives from its call sounding like "brain fever" but also what one writer called its repetition being a "damnable iteration". It looks like a bird of prey, and flies like one too, imitating the flapping glide of a sparrowhawk in the region, known as the shikra, often accompanied by mobbing small birds. Unwittingly as they mob her, birds like babblers betray their nest, into which the cuckoo will lay her egg.

Pied Butcherbird Oct 13, 2014

Miranda Krestovnikoff presents the virtuoso songster the pied butcherbird of Australia. Australian parks, gardens resonate to the flute like calls of a medium sized black and white bird with stout blue-grey bills, and a black hood. They earned their name 'butcherbird' from their habit of storing prey by impaling it onto thorns or in a tree crevice before feeding on it with their hooked bill. They can sing for up to twenty minutes at a time, appearing to improvise as they perform a mellifluous, but unpredictable performance which they deliver as a solo or a duet with another butcherbird. Australian composer David Lumsdaine, described its call as..... "a virtuoso of composition and improvisation".

Arctic Warbler Oct 10, 2014

Show notes

Tweet of the Day is the voice of birds and our relationship with them, from around the world. Miranda Krestovnikoff presents the long distant migrant Arctic warbler. These classic olive-grey warblers, slightly smaller than the European robin, with a pale eye-stripe, winter in south-east Asia, but each spring fly to northern forests to breed. This can be as far as Finland, up to 13,000 kilometres away as well as Arctic and sub-Arctic Russia, Japan and even Alaska. They do this to feed on the bountiful supply of insects which proliferate during the 24-hour daylight of an Arctic summer. A few make it to Britain, the Northern Isles, but whether they finally return to Asia is not known.
