This antshrike is a skulking understory bird that is most often detected by its distinctive duet between males and females. It forages methodically in dense thickets and is sometimes seen near army-ant swarms to snatch flushed insects. The species tolerates secondary growth and edge habitats, which helps keep its populations stable. Males and females look quite different, aiding quick field identification.
