Maroon-backed Accentor

An unusual warbler with a long bill and pale eye. The upperparts are pale, with blurry gray on the chest and rufous on the flanks. Found in humid forest at low and middle elevations, mainly in dense mid-level tangles. Similar in appearance to other longbills, but with a good view, separated by the rufous on the underparts. Also similar to Fraser’s Sunbird, but less yellow below, with a straighter bill. Most often detected by the distinctive song, a melancholy, wandering, variable series of whistles that can either descend or ascend. Sounds quite robin-like.

Vivid green bird of lowland evergreen forest canopy where it joins mixed flocks. Male has a black mask and throat. The black throat also has a dark blue center, though this can be difficult to see in poor lighting. Female is clean-faced save for a pale yellow throat and a trace of a blue mustache. Generally larger than Lesser Green Leafbird, but the two can be maddeningly difficult to tell apart. On the male Greater Green Leafbirds, look for a more extensive black mask and no traces of yellow on the forehead, while on the female, look for a yellow (not green) throat.

Very large chicken-like bird, widespread across the Amazon basin, but nowhere common. Distinguished from other tinamous by entirely gray plumage with fine black barring on the upperparts and some white speckling on the head. Gray Tinamou is also larger than other large species such as Great and White-throated Tinamous. Favors areas of upland forest and is most often encountered by voice, a single, short hollow whistle given at long intervals.
