Mountain Serpent-Eagle

Bland, unremarkable-looking medium-sized babbler of open forest, forest edges, clearings, brushy riparian, and overgrown margins of cultivation in lowland and foothill areas. Extremely generic-looking, with no bright colors, a medium-length tail, and an average bill. Evenly-proportioned body gives it a rather bulbul-like outline. Note unmarked gray face, dark gray crown, dark rufous tail, and faint brownish wash on the chest. Especially similar to Moustached Babbler, but note present species’ darker crown, plain face (no moustache), and more slender bill. Scaly-crowned is also similar, but has a bright rufous patch on the forecrown. Plainly-colored Pellorneum babblers can be confusing, but note differences in proportions and profile. Most frequently-heard song is a beautiful but eerily human-like rising series of even whistles; when duetting, one bird often gives explosive “wik!” calls in response. Also gives a quicker, more cheery, and less human-like version of the song, as well as a short melancholy up-and-down series of whistles.

Medium-sized, strikingly patterned songbird endemic to Taiwan, where less common than Taiwan Scimitar-Babbler. Brown above, white below, with rich olive-brown flanks, rusty undertail coverts, and black “necklace” of blobby black streaks. Inhabits foothill and montane forests, where it skulks in undergrowth and shrubby edge. Pairs duet, giving bouncy-sounding hoots; alarm calls harsh and grating.

A well-named antshrike of subtropical forest understory in the Andes. Male is uniform dark gray with no distinguishing features; female almost equally nondescript, plain brown overall with contrasting gray face. Stout bill with hooked tip, like other antshrikes. Usually seen singly or in pairs in the lower levels of montane forest, rarely coming into the open. Sometimes follows mixed-species flocks. Found at higher elevations than most other antshrikes. Listen for short series of “awh” notes, accelerating slightly.
