Geographical variation slight and perhaps to some extent clinal, and races intergrade; validity of races questioned, and differences may be due largely to degree of plumage wear; further study required. Birds from Gascoyne Valley (W Western Australia) sometimes separated as race gwendolenae, but appear indistinguishable from nominate. Four subspecies currently recognized.

Subspecies and Distribution
  • P. s. superciliosus (Vigors & Horsfield, 1827) – CW Western Australia E to South Australia and W Victoria.
  • P. s. ashbyi Mathews, 1911 – SW Western Australia.
  • P. s. centralis Schodde & Mason, 1999 – C Australia (S Northern Territory, N South Australia).
  • P. s. gilgandra (Mathews, 1912) – inland SE Australia (S Queensland S to C Victoria and EC New South Wales).
