Small, plain bird found at high elevations in the eastern Andes in northern Peru. Adult male is dark gray, often looking black in the field. Females and young birds are browner, especially on the lower underparts. Similar to Large-footed Tapaculo, but smaller and has a different voice. Gives low-pitched, froglike notes either in a steady series or in shorter, faster bursts. Inhabits understory of elfin cloud forest, often near tree line, and stays low where it is hard to see.
