Like most black cockatoos, Red-tailed Black Cockatoos are native to Australia.
The adult male Red-tailed Black Cockatoo is completely black except for red patches visible on the lower feathers of his tail.
He has a dark beak and no yellow spots/bars. Adult male plumage is reached at about 4 years old; juveniles resemble female plumage.
The female Red-tailed Black Cockatoo has yellow spots on her black head and wings, yellow bars on her front
and a barred red/orange tail. She has a light beak.
The Naso subspecies also called the Forest Red-tailed Black, native to the far southwestern corner of Australia
and shown in the row above, has a significantly larger (wider and longer) beak than the nominal subspecies shown in the preceding row.
Sometimes her tail is barred with yellow or orange instead of red. The northern, large-billed C. b. macrorhynchus subspecies,
above left, has pale yellow or white barring, but female Yellow- and White-tailed Black Cockatoos have no barring.
Juvenile Red-tailed have pale barring. The amount of yellow spotting on head and wings is variable.
Red and yellow barred tail; nominal subspecies
Woodworking is a favourite activity.
Some of the subspecies are endangered or threatened; some are seen as agricultural pests.
