Plumage variation considerable and confusing, leading to discrimination in recent years of three taxa which are here treated tentatively as synonyms: long-established form alticola and recently described hockingi were considered full species owing to apparently stable characters and sympatric occurrence with present species#R, but new observations of unpaired birds with alticola and hockingi plumage features within flocks of P. mitratus, combined with evidence that museum materials of such birds lack adult moult patterns, suggest that “alticola” and “hockingi” refer to variations within juvenile plumages of P. mitratus#R, while recently described subspecies tucumanus#R appears to represent individual variation within P. mitratus#R. Two subspecies recognized.
