Attractive ant-following antbird of mature rainforest. It is an obligate ant-follower, and is usually found in pairs or family groups around army ant swarms. The two sexes are uniquely distinctive: males are gray with a white eyebrow and throat and fine white tail barring; females are rusty orange with faint black patterning and fine black tail barring. While it follows army ant swarms through a variety of mature and secondary rainforest habitats, its territories are usually centered around areas of dense undergrowth within mature rainforest, like in upland ravines and around tree fall gaps. Its song is a distinctive slow, descending series of wheezy whistled notes.
