How many red tailed black cockatoos are left?

Answer 1

There are 5 sub-species of red-tailed black cockatoos, and while some are common, others are not.
They are:

• South-eastern red-tailed black cockatoo, C. b. graptogyne, (endangered - only found in southwestern Victoria and southeastern South Australia)
• Forest red-tailed black cockatoo, C. b. naso(near threatened)
• C. b. banksii found across Queensland
• Great-billed Cockatoo or C. b. macrorhynchus(found across Australia)
• C. b. samueli found across the central coastal region of Western Australia, and parts of Queensland and western NSW.

There are believed to be about only 1000 of the endangered South-eastern red tailed black cockatoos left in Australia, in the wild.

Answer 2

The South-eastern red tailed black cockatoo is classified as endangered. It is only found in south-western Victoria and south-eastern South Australia, where it is believed there are only about 1000 adult birds remaining.

There are several factors contributing to it being endangered. Bushfires are a problem, as they reduce its habitat, particularly large trees with hollows for nesting, and also reduce its food source. Agriculture has also resulted in loss of habitat. Surprisingly, the red tailed black cockatoo is largely subject to predation by the brushtailed possum which, although herbivorous, takes over the cockatoo's nests.

There are four other sub-species of red-tailed black cockatoo which are not endangered, although the Forst red-tailed black cockatoo is "near-threatened".
