Small streaked antbird. Black-and-white streaked head and underparts with a bold black eyeline and crown, brown wings and tail, and orange-red wash on the sides. Found in dense understory around forest edges and secondary growth; where it overlaps with Yellow-breasted Warbling-Antbird, largely restricted to the understory of mature rainforest, especially around tree fall gaps and along streams and ravines in upland areas. Compared to the similar Yellow-breasted Warbling-Antbird, usually has orange-red wash restricted to its sides (Yellow-breasted can be orangey but usually has extensive color on the throat and breast), and is found in mature forest habitats (not bamboo or riverside secondary growth). Song an accelerating, descending series of whistles that get rougher in tone, very similar to that of Yellow-breasted Warbling-Antbird.
