Yungas Tody-Tyrant

Small sparrow with a short tail found in grasslands including agricultural areas with grassy edges. Brownish gray above with heavy dark streaks and brownish wings, and plain gray-buff below. Note the short yellow eyebrow that does not reach beyond the eye. Usually sings a series of soft buzzy whistles from fence posts or shrubs.

A small and difficult to identify woodcreeper, widespread but often rare and seldom encountered. Smaller than most other woodcreeper species in range (slightly larger than Olivaceous Woodcreeper), with a relatively short, straight bill and weakly marked brown plumage. Note the faint pale streaking on the head and spots on the throat. Best found and identified by voice, a fast, even trill lasting between 1-2 seconds and usually heard at dawn.

A tiny swift with dark plumage except for the off-white underside from the lower breast down. Tail looks square, only sometimes showing a very marginal tail notch. Aerial and gregarious, gathering in flocks over a variety of habitats, both open and forested. Restricted to the western Lesser Sundas, where it only overlaps with one other similar species, White-nest Swiftlet. Tenggara Swiflet is smaller with a white underside, unlike that species.
