long-tailed tapaculo Scytalopus micropterus

Small, mouse-like bird of Andean cloud forest. Often looks all gray in the dark forest understory it inhabits, but it does have rusty lower underparts with dark barring. Female may show a brown tinge on her back. Similar to other tapaculo species, and best identified by range and voice. Stays near the ground and is usually hard to see. Typical song is a “ker-chick!” repeated over and over.
