Are red tailed black cockatoos endangered?

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".
