Chapin's Mountain-Babbler Turdoides chapini

A strange, chunky dull-brown forest babbler with a paler throat, a dark chestnut crown, and a warmer chestnut breast, rump, and wing panel. Juvenile has a more purplish crown. Family groups of 5–12 move quickly and noisily through the canopy and middle levels of transitional broadleaf evergreen forest between 1000 and 1600 meters of elevation, investigating thicker vegetation for food. Associates with bulbuls and could be mistaken for them, but rusty tones to plumage should clinch identification. Groups give harsh grating calls mingled with sweeter notes.
