分布与栖息地
It lives in the Veuve Nature Reserve on La Digue, Seychelles, where it inhabits dense Calophyllum forests. Although a reservation was made especially for this bird, it is common to see it outside in the trees or even in the garden of the Seychellois people. Plans were made to get this bird back into the wild on other islands of the Seychelles.

行为
It preys on insects in flight or from a perch. It also feeds on larvae and spiders. The oval bowl-shaped nest is built on branches and consists of twigs, palm fibre, and spider webs. Both parents, male and female, take care of the little bird until it grows up and each of them provides it with food, mainly in the form of flies for which it got its name.
保护状况
The International Union for Conservation of Nature lists this bird as being "Vulnerable". The threats it faces are a result of its specific habitat requirements which are incompatible with the habitat loss and fragmentation taking place on La Digue, due to increasing tourism and the expansion of settlements. Numbers of birds are thought to be in the low hundreds, and in an effort to improve its long-term hopes of survival, it has been introduced to Denis Island where there are no mammalian predators. 23 birds were moved to Denis Island in 2008 and have since successfully bred there.

Nicobar Sparrowhawk
Tachyspiza butleri
Small raptor with short wings. Male is gray above with thin brown barring on the pale underparts, and a black tail tip. Female is browner overall. Similar to Shikra, but Nicobar Sparrowhawk is smaller and paler, and has no tail bands. Known to be shy; sticks to treetops in forested habitats. Limited range restricted to a few of the Nicobar Islands.
Pulitzer's Longbill
Macrosphenus pulitzeri
An unusual warbler with a long, straight bill and a pale eye. Mostly dull olive-green with a yellowish throat. Found locally along the Angolan escarpment in dry evergreen forest at low middle elevations, mainly in dense tangles at middle levels of the forest. Could be confused with camaropteras, but larger, without a bright green wing. Also similar to some greenbuls, but smaller and shorter-tailed. Usually detected by the distinctive song: a repeated, low-pitched, two-note “peet-treeya” phrase.
New Zealand Kaka
Nestor meridionalis
A large, olive-brown parrot endemic to New Zealand. Adults have a deep crimson belly and undertail with a red-orange underwing. South Island birds are brighter with a white crown. Juveniles have a yellow base to their lower bill. A forest-dwelling parrot that is more common on offshore islands, but flourishes in areas where mammalian predators are controlled; some visit city and rural gardens. Harsh, grating “kra-aa” call is often heard before the bird is seen. The species also whistles a series of tuneful notes while perched. Distinguishable from Kea by smaller size, olive-brown as opposed to olive-green plumage, and range.
