Considerable confusion regarding type locality and subspecific nomenclature: type locality was claimed to be Bioko, apparently due to misunderstanding; under such an arrangement the Bioko race was considered nominate poliocephala, while westernmost race bore name castanonota; however, type series convincingly shown not to have come from Bioko, but probably Ghana, and plumage of syntypes matches skins from there; type locality thus emended, westernmost race becoming nominate, with Bioko race adopting name compsonota. Described race nandensis (from W Kenya) considered synonymous with carruthersi. Nine subspecies recognized.
