Swan River, Western Australia

.

Sometimes considered to include smaller and smaller-billed C. sanguinea, and in the past treated as conspecific with C. tenuirostris; on current evidence, the three (entirely allopatric) forms probably best considered to constitute three separate species. Type specimen of race derbyi previously considered of doubtful origin and locality, but subsequently validated#R; described form butleri (from near Coorow) is synonym of derbyi. Two subspecies recognized.
