Western Chat-Tanager Calyptophilus tertius

A long-tailed, shy, ground-feeding species of wet broadleaf forests with dense undergrowth, especially near streams from 700 to 2,000 meters elevation. Dark brown, with white throat that fades into gray-brown chest and belly. Primarily feeds in thick leaf litter. Rather similar to the Eastern Chat-Tanager, which is a bit smaller and has a yellow eyering. This species’ full song is a loud, whistled “tsew, tsee-ew, tsee-ew, tsu, tsu, tsu,” or variations thereon, with final notes given rapidly; often sung in fragments. Songs are more clearly whistled than those of Eastern Chat-Tanager. Call is a “chep.”
