Sydney, New South Wales, Australia.
Sister to C. boweri (which see). Races sometimes divided into three species, one in New Guinea and N Australia (superciliosa and brunnea), one in W, C & SC Australia (rufiventris), and a third in E Australia and Tasmania (nominate and strigata); despite wide range of vocal variation, however, songs of all races very similar (few recordings of brunnea and rufiventris), and detection of any difference, likely to be small, would require extensive analysis. Considerable geographical variation, and up to 13 local forms sometimes distinguished, but races intergrade widely. New Guinea population often separated as tachycrypta; differs somewhat from birds in NE Australia (Cape York, in N Queensland), but not sufficiently to warrant subspecific recognition. Other named races, all in Australia, are parryi (Kimberley district of Western Australia), roebucki (Roebuck Bay, in Western Australia) and julietae (interior NW Australia), all merged with brunnea; kolichisi (Western Australia) and whitei (interior South Australia), synonymized with rufiventris; pallescens (E Queensland), anda (NE South Australia) and halmaturina (SE South Australia and adjacent New South Wales and Victoria), all merged with nominate; and kingi (King I, in Bass Strait), merged with strigata. Five subspecies recognized.
