Young birds fledge after about 4 months and both sexes have the colouring of their mother. The best time for hand raising is at about 10 weeks when their black feathers are in place but the tail feathers are still short. The eyes of the young open around 3 weeks and the yellow down will show black pin feathers at about 6 weeks. Once the female has one egg in her nest, she will not lay another. The birds breed easily in captivity and can lay eggs every 3 weeks between February and November. However, with an increase in interest in conservation, more aviculturists are concerned about maintaining the integrity of the separate subspecies in cultivation, and so avoid crossbreeding. Birds were often previously bred without much attention to subspecies of origin. Until now, most birds in captivity have been of subspecies C. The red-tailed black cockatoo is the most commonly seen of the black cockatoos in captivity, and can be hardy and long-lived if given plenty of space. Hand-reared birds are able to learn a few words and can be quite affectionate, although males may become imprinted and unlikely to breed. Hand-raised birds can be bought for anywhere between $15,000 to $40,000 in the United States, where they are seldom seen in aviculture. In the late 1990s, red-tailed black cockatoos fetched prices of $1750 in Australia and $8900 (~US$6000) overseas. Of the black cockatoos, the red-tailed is the most adaptable to aviculture, although black cockatoos are much rarer and much more expensive in aviculture outside Australia. Populations in southeastern Australia are threatened by deforestation and other habitat alterations. They are seed eaters and cavity nesters, and as such depend on trees with fairly large diameters, generally Eucalyptus. In the more northerly parts of the country, these cockatoos are commonly seen in large flocks. The species is usually found in eucalyptus woodlands, or along water courses.
Although the more northerly subspecies are widespread, the two southern subspecies, the forest red-tailed black cockatoo and the south-eastern red-tailed black cockatoo are under threat. Five subspecies are recognised, differing chiefly in beak size. It is more common in the drier parts of the continent.
Adult males have a characteristic pair of bright red panels on the tail that gives the species its name.

The female alone incubates the eggs, while the male supplies her with food. Both sexes construct the nest, which is a large tree hollow, lined with wood chips. Yellow-tailed Black-Cockatoos have a long breeding season, which varies throughout their range. The Yellow-tailed Black-Cockatoo is found in south-eastern Australia, from Eyre Peninsula, South Australia to south and central eastern Queensland. Small to large flocks can be seen in these areas, either perched or flying on slowly flapping wings. The Yellow-tailed Black-Cockatoo inhabits a variety of habitat types, but favours eucalypt woodland and pine plantations. Young birds resemble the adult female, but young males have a smaller cheek patch. The female has a larger yellow cheek patch, pale grey eye-ring (pink in males), white upper bill (grey-black in males) and black marks in the yellow tail panels.

It has a yellow cheek patch and yellow panels on the tail. It is easily identified by its mostly black plumage, with most body feathers edged with yellow, not visible at a distance. The Yellow-tailed Black-Cockatoo is a large cockatoo. In recent years it has been in rapid decline because of native habitat clearance, with a loss of food supply and nest sites. The Yellow-Tailed Black-Cockatoo is one of five species of Black-Cockatoo in Australia.
