White-browed Triller

A large gray-and-green fruit-dove confined to the Banggai Islands. Upperparts are forest-green and head and underparts are very pale gray, except for the wine-red vent, the tiny maroon chin, and the maroon base to the yellow bill. Found singly or in pairs in forest and degraded areas in the lowland and foothills. Combination of pale underside, miniature maroon chin, and yellow bill with a red base are unique in its limited range. Song is a long series of fast-paced “whoop” notes. Number of notes varies, but can exceed 20.

A striking, mostly dark harrier with large white panels in the underwings, a white rump, and bands on the tail. The juvenile is brown with white flashes in the underwings and has a heavily-streaked chest. It quarters low over heath-like fynbos, semi-desert Karoo, and dune brush hunting for small birds and mammals. Regularly disperses irruptively north into grasslands and steppe from January to July.

Small bird of open arid shrubland and grasslands in southwestern Western Australia. Pale brown above, whitish below, with distinct pale supercilium, streaking on head chest, and long, cocked tail. Forages quietly on the ground or in thick vegetation, where difficult to see. Most easily observed in spring when males perch up in vegetation to sing. Similar to Rufous Fieldwren but no range overlap. Compare Shy Heathwren, which has an unstreaked back and head, white wing spot and darker legs.
