Aviculture
In the late 1990s, Red-tailed Black Cockatoos fetched prices of $1750 in Australia and $8900 (~US$6000) overseas. 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. Hand-reared birds are able to learn a few words and can be quite affectionate, although males may become imprinted and unlikely to breed. 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. Until now, most birds in captivity have been of subspecies C. b. banksii and C. b. samueli. Birds were often previously bred without much attention to subspecies of origin. 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.
The birds breed easily in captivity and can lay eggs every 3 weeks between February and November. Once the female has one egg in her nest, she will not lay another. An egg takes about 30 days to hatch. The eyes of the young open around 3 weeks and the yellow down will show black pin feathers at about 6 weeks. 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. Young birds fledge after about 4 months and both sexes have the colouring of their mother. Mature male birds will become aggressive to young male birds at puberty (4 years); they must be separated if caged.
The large and powerful bills of these birds can quickly and easily open a Brazil nut (normally requiring crushing in a vise or pounding with a hammer), shearing it as neatly as a laser.
Captive breeding guidelines may be found in Husbandry Guidelines for the Red-tailed Black Cockatoo (Bennett, 2008).
