Whiskered Treeswift
Hemiprocne comata
Elongated white “whiskers” and brows give this elegant species the appearance of a wise old man. Long-tailed and long-winged, like a cross between a swift and a swallow. Glossy brownish-olive with glossy blue-black wings and head. Male has chestnut ear patches, while the female has bluish ones. Sallies from exposed perches in the canopy and along clearings in lowland and foothill wet forests. Gives squeaky, excited-sounding calls and high-pitched chattering.

Spectacled Barwing
Actinodura ramsayi
The only barwing in its range which combines an unmarked face and pale underparts with a bold white eyering. Found in montane forests and adjacent scrubby areas. Forages in pairs and small flocks, usually rustling about in dense vegetation. Occasionally will emerge out onto an exposed branch, from which the bird may give several plaintive mewling notes.
Blue-throated Roller
Eurystomus gularis
A large-billed roller of primary and secondary forests that is often found sitting on branches overlooking clearings or in the canopy. Distinctive, with a bronze-colored body, a blue throat, a pale yellowish bill, and blue tail and flight feathers. Resembles and occurs alongside the related Broad-billed Roller, but Blue-throated Roller differs in its blue throat and bronzier body. Voice is a harsh “kleek,” often delivered noisily in rapid succession.
Streak-throated Canastero
Asthenes humilis
Small, plump brown bird with a fairly long tail sometimes held cocked. Has lighter brown underparts, a faint white eyebrow, and black streaking on the face and throat. Found in rocky grasslands with short grass at high elevations, where it forages on the ground between patches of grass. Compared to the similar Cordilleran Canastero, Streak-throated has more prominent streaking in the face and throat and a brown tail (reddish brown in Cordilleran). Its song is a soft, short trill, and it also gives bursts of “pit” notes.
