Dwarf Koel

Large dark swift with long sickle-shaped wings and a forked tail, which is often kept closed in a needle-tipped point while in flight. Black overall with an ashy gray throat and a thin white rump. Distinguished from needletails by proportionally longer wings, longer and more slender body, and much longer tail. Closely related Pacific Swift has a broader and brighter rump patch and a whiter throat. Faint greenish gloss on the back is diagnostic but difficult to see. Like other "fork-tailed swifts", usually seen in flight over hills, forests, and open areas. Gives high thin notes as well as a grating trills. Breeds in limestone caves.

A very large honeyeater with a long dagger-like bill. Entirely gray-brown with a whitish collar and pink naked skin around the eye. Juveniles are less olive, showing some yellow feather edging above. Confined to the island of Seram, where it is found in lowlands and foothills in forest, plantations, mangroves, and sparsely wooded areas. Differs from Seram Oriole in showing bare skin around the eye and also in shape, as it is slightly larger and relatively longer-tailed, with a bill that tapers to a finer tip and a crown is often flattened, with a peak on the nape. Gives an explosive loud “k’PROW!” call.

A small, charismatic bird of tepui highland forests. Note orange-rufous face and breast, short tail, and bold wing bars. Found only at higher elevations (above 1000 meters) in understory of humid forest with lush growth of mosses and epiphytes; usually in pairs that may join mixed-species flocks but are often found away from them. Forages deliberately, making short flights between perches and peering about for insect prey. Voice is a hollow, rolling purr, descending in pitch and usually preceded by one or two short notes; it is given intermittently and often in duet by a pair. A distinctive bird and unlikely to be confused with other species in its limited range.
