See P. fuscicapillus. Taxonomy unsettled; limits of races uncertain, and molecular analyses needed, combined with examination of birds at equivalent stages of plumage wear, and analysis of vocalizations. On basis of plumage pigmentation and pattern of feathering on cheek and neck, two groups have been distinguished, sometimes treated as two species: those from Lesser Sundas (nominate and neglectus) and CN Australia (gordoni and ammitophilus) form one group, the rest the other. Forms gordoni and ammitophilus, however, differ from other two in group in their vestigial casques, and from each other in habitat, while race yorki has uniquely cylindrical casque and silver-edged crown feathers and may be closer to P. argenticeps#R; moreover, jobiensis has almost no casque at all; thus four, five or six groups arguable, several of them potentially full species. Other proposed races include sumbanus (Sumba) and plesseni (Lembata), both merged with neglectus; pallidiceps (Wetar), synonymized with nominate; brevipennis (Utakwa R, in S New Guinea), fretensis (Hall Sound, in SE New Guinea) and trivialis (Collingwood Bay, on N coast of SE New Guinea), all subsumed into novaeguineae; and confusus (N Queensland), treated as synonym of yorki. Ten subspecies currently recognized.
