The secretive chestnut-backed antbird (Myrmeciza exsul) male has a blackish head, neck and breast, and the rest of the upperparts, wings and tail are chestnut. Contrary to its name, it has no special attraction to ants, though it does so opportunistically when a swarm passes through a territory. It is found in humid forests in Central and South America (Chocó-Magdalena), ranging from eastern Nicaragua to western Ecuador.
