Sunda Collared-Dove

A typical medium-sized brown-and-white buzzard that was only recognized as distinct in 2010. The underparts are whitish buff with heavily streaked underparts (lighter on the throat). Underwings display significant contrast, with pale primaries and secondaries standing out against black 'wrists' and rusty 'wingpits'. Juveniles are buffier and less heavily streaked. Uncommon resident endemic to Socotra, mostly between 150–800m, preferring ravines and cliffs; other buzzards are vagrants. Calls like other buzzards.

A small bird of lowland and montane forest and edge. Unmistakable; the only nuthatch in its range. Blue above with a black edge to the wing, a black forehead, a thin black stripe behind the eye, pale pink underparts, and a yellow bill, eye, and eye-ring. Often joins mixed-species flocks. The only woodpecker similar in size is Philippine Woodpecker, but Sulphur-billed Nuthatch is blue rather than brown. Voice includes high-pitched, descending shrieking calls and sharp staccato chips.

Flocks of these large sea ducks enliven northern coastlines. Males are white and black with a soft suffusion of green on the nape. Immature males are variable and messy-looking with patches of black and white. Females vary from rich rufous-brown to cold grayish, always with extensive black barring covering body and wings. Slight variation in bill shape and color across subspecies, especially obvious on males; Pacific birds have brightest orange bills, most others have greenish bills. Dives to feed on mollusks and other crustaceans. In late summer, look for flocks of females with dozens of ducklings; broods often join together. Compare females with other eider species, and note details of bill and head shape.
