Spiny-faced Antshrike is a unique, streaked antbird restricted to eastern Panama and extreme northwestern Colombia. It has been recorded at few localities, with Nusagandi in Panama being perhaps the most reliable site to find this species in recent years. It is best detected by its song, a rising series of whistles. Both sexes share diffuse streaking on the head and mantle. The female is brown overall, while the male is brown above and gray below. Spiny-faced Antshrike occurs in evergreen forest in lowlands and foothills. It moves about with mixed understory flocks, sallying to vegetation in pursuit of arthropods. The nest is a cup of rootlets placed in a branch fork.
