Birds of C Pacific sometimes placed in separate race rothschildi. Races have been suggested to form a N–S cline, and species may be better considered monotypic. Four subspecies normally recognized.

  • P. r. westralis Mathews, 1912 – E Indian Ocean.
  • P. r. roseotinctus (Mathews, 1926) – SW Pacific.
  • P. r. melanorhynchos J. F. Gmelin, 1789 – W, C & S Pacific.
