观察细节
An amazingly distinct taxon, far smaller than Large-billed Crows in the Ryukyu or the mainland, with much less domed forehead and much more delicate bill. Voice also seems somewhat different, and it occurs from urban area to forests, very catholic in habitat use. Seems as distinct as any of the Australian corvid species, surely a split in the complex which is way overdue an analysis
