Black-vented Shearwater
Puffinus opisthomelas
Small brown-and-white shearwater with messy appearance. Especially note smudgy face and neck. Found in warmer ocean waters off the west coast of North America, often close to land. Found singly or in small flocks, sometimes with other shearwaters. Most similar to Manx Shearwater but ranges do not usually overlap; also look for smudgier head, longer bill, and darker undertail coverts on Black-vented. Also compare with much larger Pink-footed Shearwater.

Barred Antthrush
Chamaeza mollissima
Compact brown bird with a stubby black bill. Warm reddish brown with heavy black-and-white barring on the undersides, face, and eyebrow. Walks around the ground in dense montane forest with a springy gait, bobbing its tail up and down with each slow step. Exceptionally timid bird heard far more often than seen; listen for its long hooting song, an accelerating series of low toots.
Chocolate-backed Kingfisher
Halcyon badia
A ventriloquial forest kingfisher that is more often heard than seen as it perches in the subcanopy. Distinctive with its blood red bill, broadly chocolate-brown upperparts, white underparts, and bright blue wing patches and tail. Nests in arboreal termite mounds. Song is a series of ten or more easily imitated whistles that rise and then abruptly fall in pitch, “pew pew pew PEW PEW PEW pew pew.”
Rufous-headed Tanager
Hemithraupis ruficapilla
Small and restless tanager found in the canopy of forest borders and lighter woodlands where it often accompanies mixed-species flocks. Males have a cinnamon head with a yellow side to the neck, and an orange throat and rump. Males are olive-green above and on the tail and off-white below. Females are quite uniformly olive-green with gray flanks and are identical to female Guira Tanagers.
