Sharpe's Drongo

A plain clay-brown laughingthrush with a long, curved yellow bill. Largely without distinguishing plumage features, but note weak white brow, blue-gray tinge to the wings, and small black patches on the “elbow” and face. The only laughingthrush in much of its range. Forages in hilly and montane regions, where it often moves about noisily in medium-sized flocks in scrubby, brushy habitat, often near waterways. Long rambling song melodious and thrush-like; calls include fluid whistles, nasal chattering, and quiet peeping.

A mostly dark-brown petrel with a white underbody and a strongly hooded appearance. Very similar to the larger Tahiti Petrel, but has a smaller, thinner bill and more rounded wings. Erratic flight style is much more fluid and “flappy” than that of Tahiti Petrel, which prefers to soar endlessly on long thin wings. Similar to Phoenix Petrel, but lacks a pale throat and a pale bar on the leading edge of the underwing.

A tiny, rotund flycatcher found singly in the understory of montane forest from Panama to Peru. Very nondescript plumage: darker olive above with a dull tawny breast and yellowish belly. Looks uniformly brownish in bad light. Usually stays low, where it perches quietly and sallies out to glean insects. Often detected by its snapping sounds and whirring wingbeats. Occurs from around 700–2,000 m, typically lower than Rufous-headed Pygmy-Tyrant but some elevation overlap.
