Races sometimes considered to represent two separate species, and may be genetically divergent: rubeculus is smaller (effect size for male wing −2.13; score 2), with rufous-brown vs whitish breast (but some tendency in some populations of nominate towards rufous; hence only 1); unclear zone of intergradation or hybridization (possibly 2) supposedly in W Queensland; thus species status approached, but analysis of available recordings indicates that vocalizations are similar and hard to distinguish#R. Geographical variation largely clinal, size becoming larger and plumage greyer from W to N & E, and a dozen races sometimes recognized; other proposed races include strepitans (lowland S New Guinea), nigrescens (NW Western Australia), intermedius (N Western Australia E to arid interior Queensland and N South Australia), bamba (Melville I), brownei (Cape Arnhem Peninsula), mountfordae (Groote Eylandt), cornwalli (coastal NE Queensland S to Cairns), trivirgatus (coasts of S Queensland and New South Wales) and tregellasi (SE South Australia E to SE New South Wales). Two subspecies currently recognized.
