Cholo Alethe Chamaetylas choloensis

A robust, chocolate-backed forest skulker with clean-cut pale underparts washed gray, and a distinctive white throat and outer tail tips. Singles and pairs are shy and inconspicuous residents in the dense under-story of mid-altitude forest, between 700–1900m. May follow army-ant swarms, where it loses its fear of humans. Calls a loud downslurred quavering “tiiyuuu” and harsh chitter in alarm. Similar White-chested Alethe differs from Cholo by having gray (not brown) face and rufous tail lacking white.
