New Guinea; error = Luzon, Philippines.
Commonly considered to include C. dobsoni, and hitherto always C. panayensis. Races rather variable in plumage and size, and some, e.g. the strikingly large guillemardi and the notably isolated vordermani (both of which may be threatened owing to habitat loss), may in future be treated as full species. Some authors#R consider Sundaic forms (including difficilis) to represent a separate species, distinct from Philippine taxa, but vocal analysis suggests differences between Philippine and Greater Sunda taxa not strong, although voice of kochii appears relatively distinctive. Race †cebuensis extinct. Thirteen extant subspecies recognized.
