Described by French naturalist Anselme Gaëtan Desmarest in 1826, the genus Calyptorhynchus has five species. They are all mostly black in colour, and the taxa may be differentiated partly by size and partly by small areas of red, grey and yellow plumage especially in the tail feathers. It is the largest genus of the "dark cockatoo" subfamily Calyptorhynchinae which now is recognized to contain also the other sexually dichromatic species, the Gang-gang Cockatoo and probably the cockatiel which despite its unique appearance may actually be the closest living relative of Calyptorhynchus (Brown & Toft, 1999, but see Astuti, 2004?). Two subgenera (Calyptorhynchus and Zanda) are recognized based on the colouration of the species, and presence of sexual dimorphism:
- Subgenus Calyptorhynchus - black-and-red cockatoos
- Red-tailed Black Cockatoo, Calyptorhynchus (Calyptorhynchus) banksii
- Glossy Black Cockatoo, Calyptorhynchus (Calyptorhynchus) lathami
- Subgenus Zanda - black-and-yellow/white cockatoos
- Yellow-tailed Black Cockatoo, Calyptorhynchus (Zanda) funereus
- Carnaby's Black Cockatoo, Calyptorhynchus (Zanda) latirostris
- Baudin's Black Cockatoo, Calyptorhynchus (Zanda) baudinii
