Scaly-breasted Wren
Microcerculus marginatus
Dark, short-tailed wren, quite shy and difficult to see. Overall brown with paler grayish throat and rather long, straight bill. Some populations have more scaling on breast than others. Found on the ground inside forest, where it makes an interesting song. Listen for a series of whistled notes, starting off high-pitched with a few in rapid succession, then each note dropping in pitch and spaced further and further apart. The whole series can last for minutes. Far more often heard than seen.

Turdoides leucopygia
A dark brown babbler with a bright white rump. The pattern on the head and breast varies widely across this species' range; birds can have a completely white head, a white face mask with a dark rim, or a black throat and white cheek patch. The extent of the pale scaly markings on the breast also varies. Found in moist woodland, forest edge, and scrub, almost always in groups of up to ten individuals. Easily separated from other babblers in its range by the white rump. The call is a raucous babbling, usually given by a whole group in chorus.
