The southern white-fringed antwren is a small antbird that creeps and hops through dense scrub, often flicking its tail to reveal the namesake white fringes. Pairs frequently duet, with male and female delivering contrasting phrases. It prefers edges, restinga, and other low, brushy habitats rather than deep forest. Though called an antbird, it is not an obligate army-ant follower and mostly gleans small arthropods from foliage and twigs.
