Gray-sided Flowerpecker

A medium-sized greenish-gray bird with a black cap and a carrot-colored bill, endemic to the middle and high elevations of the mountains of Grand Comoro. Found in humid forest and in adjacent plantations and secondary areas. Often in small, noisy groups. Very similar in appearance to Madagascar Bulbul, and they overlap at moderate elevations, especially in degraded habitats. Grand Comoro Bulbul is separated by the slightly larger size, the olive tint to the plumage, especially on the back, the yellowish tint to the underparts, and the paler belly and undertail. Its song is an unmusical series of rattling and scraping notes, often given from a high perch, similar to Madagascar Bulbul’s, but slightly lower-pitched and more metallic. 

The southwestern counterpart of the Red-billed Blue-Magpie, this colorful long-tailed corvid also forages in noisy flocks. Similar in coloration to Red-billed, but Yellow-billed is paler blue overall, with a small white patch at the back of the crown instead of an extensive white stripe, and a bright yellow bill instead of a scarlet one. Primarily found in Himalayan hill forest, with disjunct populations in northwestern Myanmar and northern Vietnam.

An attractive, medium-sized, long-tailed raptor. Mostly gray with a black uppertail and wingtips. There is yellow bare skin at the base of the bill, and the legs are red. Immature birds are mostly brown. Found in dry savanna and thornscrub, alone or in pairs. Similar to Dark Chanting-Goshawk; adults separated by their yellow facial skin, and both adults and immatures by their white rather than barred gray rump patch, which is obvious in flight. The calls include a long squeal and a chanting series of “pwek” notes.
