Several red-tailed black cockatoo calls have been recorded. Like other cockatoos, the red-tailed black cockatoo or Banksian can live a very long time in captivity in 1938, ornithologist Neville Cayley reported one over fifty years old at Taronga Zoo.Īnother bird residing in London and Rotterdam zoos was 45 years and 5 months old when it died in 1979. Juvenile red-tailed black cockatoos resemble females until puberty, which occurs around four years of age, but have pale yellow barred underparts.Īs the birds mature, the males gradually replace their yellow tail feathers with red ones the entire process takes about four years. Black cockatoos are almost exclusively left-footed (along with almost all other cockatoos and most parrots). In common with other cockatoos and parrots, red-tailed black cockatoos or Banksians have zygodactylous feet, two toes facing forward and two backward, which allow them to grasp objects with one foot while standing. Male birds weigh between 670–920 grams (1.5–2 lb), while females weigh slightly less at 615–870 grams (1.25–1.75 lb).
The underparts are barred with fine yellow on a black base. Red-tailed black cockatoo females are black with yellow-orange stripes on the tail and chest and yellow to red patches on the cheeks and wings. The tail is also black and has two bright red side panels. The plumage of the male is all black with a prominent black crest made up of elongated forehead and crown feathers. Rufous-tailed black cockatoos are about 60 centimeters (24 in) in length and are sexually dimorphic.
