Tapajos Fire-eye

Unmistakable hummingbird with long, scissor-shaped tail, overall green with decurved bill and white spot behind eye. Male recalls Violet-fronted Brilliant but with long and forked black tail and blue forehead; female very different, with shorter but still forked tail, white throat, green-speckled chest, and buffy belly, recalling female of Long-tailed Sylph. Found alone inside humid forests or forest borders at low to mid levels, often at Heliconia patches. Voice a short burst “tsi, tsi, tsip.” No similar species in its very limited range. Endemic to the Paria peninsula of northeastern Venezuela.

Gray finch-like bird known from only a few sites in the Andes of northern Peru, including steep slopes above the Marañon Valley. Adult has bright yellow bill and legs, black mask, and white outer tail feathers that are hard to see when perched. Young birds have less black on the face and duller bill and legs. Inhabits arid regions with dense, scrubby forest. Forages mainly on the ground, but perches up higher to sing. Typical song is a rising, tremulous whistle.

A plump, large-headed, brownish bird with an extremely long tail. Plain overall with no distinctive plumage features; look for pale eye and stubby bill. Difficult to see, but often heard giving an accelerating series of hard chip notes. Usually solitary or in pairs. Skulks through low, dense vegetation, especially chaparral. Restricted to the Pacific coast of North America, from Oregon to northern Baja. Not closely related to any other species in the Western Hemisphere. Might be confused with Bushtit, but larger and much different behavior and vocalizations.
