Stiles's Tapaculo Scytalopus stilesi

A standard Scytalopus tapaculo: plain dark gray with browner flanks and rump. Acts like a mouse, scurrying around on or near the ground within montane forest. Extremely limited range in the central Andes of Colombia. Far more often heard than seen. Listen for froglike churring song, given as a long series of short bursts.
