Trilling tapaculo Scytalopus parvirostris

Tiny, compact gray bird. Females are slightly duller, with brown lower sides and rump. Like most tapaculos, they are usually very shy and rarely seen in the open. Nearly identical to Tschudi’s Tapaculo, which is found at higher elevations where the two overlap; their songs are also very different. Trilling Tapaculo’s song is a long, rapid chatter.
