Papyrus Yellow-Warbler

A large pigeon with a green back, gray underparts, a darker gray head, and a bold white eye-ring. Juveniles are merely duller versions of adults. A bird of lowlands and hills, found within the canopy of forest and forest edge, normally in singles, pairs, or small groups where fruiting trees are present. Routinely heard call is a descending series of six deep hooting notes: “hoot-hoot-hoot-hoot-hoot-hoot.”

Medium-sized robin with orange underparts and an olive-brown back. The tail is uniformly rufous, lacking the dark center of a typical robin-chat. There is some geographical variation, with the western birds showing a black cap and the eastern birds a gray one. Found in the undergrowth of various forest types at low and middle elevations. Shy and retiring. The song is a highly variable mix of notes which usually includes imitations of other bird species. Similar to akalats, but separated by its white eyebrow.

Short-tailed antbird found in the understory of mature rainforest. Forages singly or in pairs, clinging sideways to vertical stems close to the ground; often follows army ant swarms, but usually does not associate with mixed species flocks. Males are gray with black scalloping on the back and black tail with white tip. Females vary in plumage geographically but are generally tawny buff with similar diagnostic black markings on the back and black-and-white tail; underparts gray in northeastern Amazonia, and underparts gray and upperparts uniform brown in southwestern Amazonia.
