Identification
Dark bird of highland forest understory. Male is entirely dark gray except for bold white wing spots; female is brown above and rufous below with a gray face. Inhabits tall premontane forest, generally between 500–1800 m on tepui slopes, and is especially likely to be found in steep terrain and in areas with many large, mossy boulders. Usually found in pairs that forage for insects on or near the ground, probing into crevices and tossing aside leaves, much like others of genus; does not typically join mixed-species flocks. Song is a long series of sharp notes, swelling in volume and dropping in pitch at end. Very similar to Spot-winged Antbird of lowlands, which it replaces at higher elevations (no known overlap); best distinguished by voice and habitat.
