See C. fuliginosus and C. montanellus. Races fall into groups on basis mainly of plumage characters: greyer “campestris group” (also including rubiginosus); rufous-brown and less streaked “isabellinus group” (with wayensis); pale “dorrie group” (with hartogi); and long-billed race winiam, on its own; limited vocal evidence does not indicate possible species-level divergence among these groups, but much more material needed. Proposed race ethelae (Yorke and Eyre Peninsulas, in South Australia) included in nominate. Seven subspecies recognized.

Subspecies and Distribution
  • C. c. rubiginosus A. J. Campbell, 1899 – CW coast of Western Australia from Exmouth Gulf S to near Geraldton.
  • C. c. dorrie Mathews, 1912 – Dorre I, in Shark Bay (Western Australia).
  • C. c. hartogi Carter, 1916 – Dirk Hartog I, in Shark Bay.
  • C. c. wayensis Mathews, 1912 – saltlakes between S Great Sandy Desert and Meekatharra–Sandstone, in C Western Australia.
  • C. c. campestris (Gould, 1841) – S Western Australia (Nullarbor Plain E from Balladoni–Israelite Bay) and S South Australia (E to coastal Eyre Peninsula and S Yorke Peninsula, S Flinders Ranges, S L Frome Basin and W Murray Mallee).
  • C. c. isabellinus North, 1896 – lower Finke R S to Coober Pedy, SW rim of L Eyre Basin and N part of L Frome Basin, in South Australia.
  • C. c. winiam A. J. Campbell & A. G. Campbell, 1927 – SE South Australia (E from Meningie and the Coorong) and NW Victoria (Big and Little Deserts).
