From Wikipedia, the free encyclopedia
The genus Calyptorhynchus has five species and 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, but they may ultimately be considered distinct genera:
- Subgenus Calyptorhynchus - black-and-red cockatoos
- Red-tailed Black Cockatoo, Calyptorhynchus (Calyptorhynchus) banksii
- Calyptorhynchus (Calyptorhynchus) banksii banksii
- Calyptorhynchus (Calyptorhynchus) banksii graptogyne
- Calyptorhynchus (Calyptorhynchus) banksii macrorhynchus
- Calyptorhynchus (Calyptorhynchus) banksii naso
- Calyptorhynchus (Calyptorhynchus) banksii samueli
- Glossy Black Cockatoo, Calyptorhynchus (Calyptorhynchus) lathami
- Calyptorhynchus (Calyptorhynchus) lathami lathami
- Calyptorhynchus (Calyptorhynchus) lathami erebus
- Calyptorhynchus (Calyptorhynchus) lathami halmaturinus
- Subgenus Zanda - black-and-yellow/white cockatoos
