Until recently, the Short-billed Black-Cockatoo, C. latirostris, found in south-western Australia, was considered a subspecies of the Yellow-tailed Black-Cockatoo. This species has white, instead of yellow, panels in the tail. Another similarly sized black-coloured cockatoo is the Red-tailed Black-Cockatoo, C. magnificus. This species overlaps with the range of the Yellow-tailed Black-Cockatoo in south-eastern Queensland. It has red panels in the tail, and spotting on the body and head. The smaller (48 cm) Glossy Black-Cockatoo, C. lathami, also has red panels in the tail.
