Thicket Antpitta is found from eastern Honduras, discontinuously, southward to southwestern Colombia, and includes two Central American and one South American subspecies. Previously Thicket Antpitta was considered conspecific with White-lored Antpitta (Hylopezus fulviventris), which is an exclusively Amazonian species. Morphologically, Thicket Antpitta is distinguished from other Hylopezus by the much less well defined and duller streaking below, and its predominantly buffy rufous underparts. Thicket Antpitta inhabits lowland habitats below 900 m and, as its name suggests, prefers dense, tangled, thickets around streams and treefalls, also occurring along forest edges and into adjacent plantations. The species is generally fairly common, but like all other Grallariidae, is more easily heard than seen. The reproductive biology, diet, and behavior of Thicket Antpitta are almost completely undocumented.
