Uncommon but widespread, Rufous-crowned Antthrush is a resident of the forest floor and low undergrowth. They forage on the ground, where they walk with tail cocked, flipping over leaves in search of insect prey. Both sexes are similar in appearance, but juvenile birds have some white on the lores and throat. Although mostly distinctive in plumage, they can be separated from the similar Black-faced Antthrush by their bright rufous crown and black on the breast. Additionally, Rufous-crowned prefers terre firme forest, whereas Black-faced is found in seasonally flooded areas. Like other antthrushes, Rufous-crowned is heard much more frequently than seen; their song is a fast series of descending then ascending notes, having a clear and somewhat mellow quality.
