Chocolate-vented Tyrant

A fairly small bird of lowland and foothill forest floor or dense undergrowth. Warm brown on the upperparts, crown, and sides, with fine buff streaks on the sides and blackish underparts heavily streaked white. Note the contrasting white throat, the black-and-white moustache stripes, and the white stripe from above the eye to the back of the head. Unmistakable in range. Voice includes a variety of medium-pitched whistles, including repeated piping, downslurred notes, plus complex jumbled songs and imitations of other bird species.

Very small bird of humid tropical forest and edge. Favors vine tangles at mid-upper levels, where moves actively, holding its tail cocked and flopping it from side to side. Appearance is distinctive, with buffy face, very long thin bill, and fairly long tail with white tips. Similar to Long-billed Gnatwren but has three white spots on outer tail feathers and a slower, sometimes multiparted chattering song. Easily overlooked, but vocal.

Tiny, mouse-like bird of tepui forest understory. Entirely dark rufous-brown with a stubby tail. Found only in humid, mossy forest on tepui slopes, mostly above 1000 meters, where it is difficult to see, staying close to the ground as it crawls over roots, rocks, and large branches. Usually encountered alone and does not follow mixed-species flocks. Most easily detected by its extraordinary song: a variable series of short, pure whistles, rising and falling but usually ending with several notes on the same pitch; humanlike and easily imitated. May pop into view in response to imitation or playback, bobbing nervously before disappearing. Could be confused with Tepui Wren, but is darker brown overall and lacks buffy eyebrow.
