Mountain Sawwing
Psalidoprocne fuliginosa
An entirely brownish-black swallow with darker wings and a forked tail. Often encountered in groups at the forest edge and in montane grassland. Only found on Bioko, where it is the only sawwing, and on Mt. Cameroon, where it is the common sawwing of high elevations. Calls are short, liquid “shu-shu” notes. Appears similar to other sawwings, especially to young Black Sawwings, but Mountain Sawwing is completely dark all over, including on the underwing.

Black Honey-buzzard
Henicopernis infuscatus
A distinctive raptor confined to New Britain. Entirely blackish-brown with indistinct dark markings and a beady pale eye. In flight appears long-tailed and broad-winged, with well-pronounced “fingers” on the outer wing; from below, note bold white bars on the tail, outermost wing feathers, and trailing edge of the wings. Juveniles resemble adults. Found in forest from lowlands to hills. Unmistakable in its limited range, where no other similar raptors occur. Call consists of a series of upslurred whistles, rapidly gaining in pace.

Green-headed Sunbird
Cyanomitra verticalis
Medium-sized sunbird in which males have an iridescent green head and breast, and females a green helmet. Depending on the light, these green areas can sometimes look blue. The pale yellow shoulder tufts are usually hidden. Found at low and middle elevations in lush woodland, gardens, and forest. Often in pairs, and sometimes in mixed-species flocks. Vocalizations include mewing and scolding calls, and a song that starts with hesitant notes but then breaks into a long trill. Male similar to male Blue-throated Brown Sunbird, but paler overall, with a larger area of iridescent green rather than blue on the head.

Plain Gerygone
Gerygone inornata
A tiny, warbler-shaped songbird confined to the eastern Lesser Sundas. Upperparts gray-brown; underparts clean, unmarked white. Note subtle white mark between bill and eye, and beady-eyed appearance. Juveniles washed yellow below. Inhabits forest, edge, mangroves, and scrub from coast to mountains. Sits high in the understory, singly or in pairs. Unmistakable, as the only tiny gray-and-white warbler-like bird in range. Warbling song comprises a series of high-pitched, descending whistled phrases such as “pee-pee-ooo-ooo-pee-ooo-ooo”. Calls often and for prolonged periods.
