Austral Blackbird

The only batis on Bioko. Patterned like a typical batis, with a white belly and throat, black wings with a white bar, and a black face. Males have a black crown, a black back, and a black chest band, whereas females have a gray crown, a gray back, and a rusty chest band. Both sexes have limited white above the eye that can appear like a broken eyeline. Infrequently encountered but widespread from lowland forest to mid-montane forest, where it can be seen in forest and disturbed forest, including plantations. Songs include a series of high-pitched whistled notes, and a few harsh notes followed by a fast trill that descends slightly in pitch. 

Short-tailed lark with a streaky brown back and inky black streaks on the chest. General coloration very similar to various other larks, but the shorter tail Indochinese Bushlark separates it from Australasian Bushlark and migrant or vagrant larks. Song is a series of clear cricket-like trills, given from the ground, a perch, or the air. Calls include similar trilling, as well as whistles. Inhabits open dry land such as fields and grasslands with small trees and bushes dotted around. Unlike skylarks, readily perches on trees and bushes.

A distinctive swift of lowland forest with a square tail and bulging wings that are “pinched” at the body and widest in the center. Wings, back, and throat are blackish, while belly, tail, and rump are white. Could be confused with Cassin’s Spinetail, but Sabine’s Spinetail’s tail extends out beyond the wings, giving it a typical swift appearance. Call is a high-pitched twitter.
