    Calyptorhynchus: Brief Summary
    provided by wikipedia

    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 sole genus of the "dark cockatoo" subfamily Calyptorhynchinae. Studies based on the mitochondrial DNA 12S gene fragment suggested that other sexually dichromatic species, the gang-gang cockatoo as well as the cockatiel may be the closest living relatives of Calyptorhynchus (Brown & Toft, 1999). However, subsequent studies, including more genes confirm the morphological taxonomy with the gang-gang cockatoo most closely related to the Galah, within the white cockatoo group, and with the cockatiel as a third distinct subfamily of cockatoos. 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 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 Yellow-tailed black cockatoo, Calyptorhynchus (Zanda) funereus Calyptorhynchus (Zanda) funereus funereus Calyptorhynchus (Zanda) funereus whiteae (not widely accepted) Calyptorhynchus (Zanda) funereus xanthanotus Carnaby's black cockatoo, Calyptorhynchus (Zanda) latirostris Baudin's black cockatoo, Calyptorhynchus (Zanda) baudinii
