David's Fulvetta

Chocolate-brown thrush with finely scaled white underparts. Very similar to Himalayan and Sichuan Thrushes, with which it was once considered a single species. Alpine is shorter-billed than the other two species, with a darker brown forehead than Sichuan Thrush; averages longer-legged and longer-winged than Himalayan Thrush. Long-tailed Thrush can also be similar, but lacks Alpine’s intense throat and chest speckling, and has thin but prominent pale wingbars. Alpine Thrush breeds in open rocky alpine areas with scattered shrubbery between 3000 and 4500 meters of elevation, though it descends lower into the foothills during winter. Song is simple but not altogether unmusical, consisting of fluid warbling notes and squeaky grating ones. 

A fairly small, slender bird of lower montane grassy valleys. Warm brown above and on the belly, with a white throat and a faintly streaked grayish chest. Note indistinct pale brow and pale barring across the base of the undertail. Very skulking. Similar to Long-tailed Bush-Warbler, but has shorter tail and grayish rather than deep brown underparts. Also similar to Philippine Bush-Warbler but with less distinct pale eyebrow. Song is a sequence of piercing and grating ringing notes repeated at regular intervals.

Small round songbird found in heavy vegetation along creeks and thick wet forest, including bamboo clumps, of northern-central Australia. Brown above, pale below, with broad white supercilium, dark ear coverts, peachy-rufous flanks and undertail, and white markings in wing and tail. Usually carries tail cocked upright. Compare White-browed Robin, which is completely white underneath (and note range). Vocalizations include pleasant, repeated soft whistle (with 3-5 notes) and a sharper whistled call.
