Races sometimes considered separate species, differing in plumage and in voice#R; further study required. On Timor, populations show morphological and vocal variation, e.g. birds on Mt Ramelan paler and greyer than those on Mt Mutis, and those on Atauro I vocally distinct; study required in order to assess taxonomic implications. Population on Roti I (off S Timor) previously included in nominate, but apparently represents an undescribed taxon#R. Race floresianus previously listed as floris, but this name is preoccupied when present species and P. montis are placed in same genus#R. Two subspecies recognized.
Affiliation of Roti I population unclear, may be an undescribed taxon#R.
