Orange-crowned Manakin
Heterocercus aurantiivertex
Dull manakin of seasonally flooded swamp forest in Amazonian lowlands. Male is less colorful than most manakins, with brown upperparts, cinnamon underparts, and a white throat; his orange crown is usually hidden and not often seen in the field. Female is duller; she is mostly olive-brown with a pale throat and face, and lacks a crown patch. Usually seen at lower to middle levels of forest along streams and lakes. Typical song is a rapid trill with undulating pitch.

Slender-billed Miner
Geositta tenuirostris
Distinctive tan bird with a thin curved bill. Forages on the ground in rocky high-elevation grasslands and pastures, especially near water and in damp areas. Usually keeps an upright posture and looks heavy-chested with a short tail. The males sing in flight displays, giving a song that is a long series of “pip” notes. Its call is a nasal laughing “heew,” recalling a flycatcher or even a small gull.
Sula Scops-Owl
Otus sulaensis
A small brown owl with indistinct ear tufts (often not visible) and yellow irises. Largely brown, mottled with dark streaks and markings over much of the body, with pale and white markings on the wings. Inhabits forest and trees within swamps, mainly in the lowlands, but sometimes into the hills too. Distinctive: restricted to the Sula Islands, where it is the only small brown owl. Song is a tremulous, trill-like whistle repeated in quick succession (“brew-ooo”). Also gives a high shrill screech note.
Cassin's Vireo
Vireo cassinii
Fairly dull vireo, intermediate between Blue-headed and Plumbeous. Grayish-olive overall, but with yellowish flanks and greenish back. Note white spectacles contrasting with gray head and two whitish wingbars. Breeds in mixed coniferous forests, especially in mountainous areas; winters in Mexico. Often separable from Blue-headed and Plumbeous Vireos by range, but can overlap during migration and winter. Cassin's is less contrasty than Blue-headed, especially between the gray face and whitish throat, and the greenish back blends into the nape and crown. Some birds are best left unidentified.
