Medium-sized, sluggish bird of tall rainforest. Males mostly gray and black; females very different, with dull to bright cinnamon head and breast, which can aid identification since this species generally occurs in pairs. Often found along river edges and in areas with much vine growth in the mid-story. Hops slowly through vegetation, searching for insects; found alone or with mixed-species flocks. Told from other antshrikes by song and brightly colored female; males have more extensive white wing markings than most other antshrikes. Song is a rapid series of notes with a trogon-like quality.
