Subspecies
Sometimes divided into subspecies, with recognition of petiti of Gabon to central Zaire, and whitesidei of south-central and eastern Zaire, but in view of great individual variation in plumage within ranges of all proposed subspecies, and overlap of characters, the species is probably best treated as monotypic until more extensive studies are made.
