Citron-headed Yellow-Finch

Small songbird with bright yellowish upperparts and white “goggles.” Most subspecies have gray underparts; subspecies “unicus” of Sumbawa and Flores has a yellow belly. Compare with other white-eyes in various parts of their range; note present species combination of dark iris and yellow back. Inhabits a wide range of different wooded habitats across its range, including coastal scrub, mangroves, inland forests, and forest edge. Forages actively in small to medium-sized flocks, sometimes mixing with other species. Can be quite common on small islands. Twittering song is bright but unremarkable. Most frequently given call is a somewhat variable high-pitched, descending “djee.”

A drab, long-tailed brownish greenbul. The upperparts are brown and the underparts paler olive-gray. Also note the long bill, brown eye, and slightly paler throat. Found in forest at low and middle elevations, preferring the understory and middle levels of the forest. Separation from other greenbuls is tricky. Very similar to Cabanis’s Greenbul, but lacks pale eye-ring and has darker underparts. More robust and longer-billed than other similarly dull greenbuls, such as Little Greenbul, with a slightly more contrastingly pale throat. The inconspicuous song is a series of low-pitched whistles, often followed by a descending series of several rasping calls. Also gives a series of scolding calls on an even pitch. 

A large gray-brown oriole with a straight, heavy bill. Main field mark is an ill-defined dark mask on the feathered face. Underparts paler than upperside. Juveniles display rufous-edged wings. Singles or pairs can be found in forest, forest edge, mangroves, and woodlands in lowlands and foothills. Similar to Buru Friarbird, but dark facial area is feathered, not bare; bill shape is thick and straight; and tail is shorter. Variable song consists of around three fluty notes, often rising and loudest on final note: “ku-wuWOOO.”
