north-west coast of Australia.
Often considered conspecific with C. torquatus (which see), but differs in its black vs white lores (3); white vs grey-washed whitish throat to mid-belly (2); much stronger white wing-flash (2); paler, greyer back, scapulars and rump (ns); and slightly elongate black line extending down neck sides (ns); voice also said to be different, but further evidence required. Race colletti often synonymized with nominate, but seems reasonably distinctive. Proposed race latens (Uwins I, in N Western Australia) included in argenteus. Type locality of nominate disputed; if this name is instead applicable to Arnhem Land form (with type locality of Port Essington), Western Australian form then takes name latens. Two subspecies recognized.
