White-striped Warbler

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.”

Small green macaw of lowland rainforest. Favors swampy areas, especially those with palm trees, which it uses for nesting. Frequently calls in flight, a pleasant rolling “greeah.” Red belly can be hard to see at a distance, but is diagnostic if seen well. Similar to Chestnut-fronted Macaw, which has maroon (not yellow) underwings, white (not yellow) facial skin, and a pale (not dark) eye.

A large finch of extreme conditions, this is a breeder of sparsely vegetated, often barren environments such as glacier and cliff edges, rocky slopes, scrubby open meadows, and boulder fields; descends into open or scrubby habitat in the winter. Male is dark streaky brown with a crimson face and breast; female is streaky brown all over with no hint of a facial pattern. Large size and habitat serve to distinguish this from similar species.
