Subspecies
No subspecies.
Forms a superspecies with other members of genus, as a series of non-overlapping mountain-top replacements, and all sometimes considered conspecific. Their vocalizations seem fairly close, but plumage patterns differ to an extent not found within species-level taxa in the Furnariidae. Birds from southern Puno (Peru), with darker plumage and probably significantly smaller body size, appear to represent an undescribed taxon.
