General Information There are five different species of the red-tailed black cockatoo mainly distinguished by their beak size. The south-eastern red-tailed black cockatoo is found mainly in the south-east of South Australia and the south-west of Victoria. It is endangered as its overall population is 1400 but its status is not critical. The biggest threat for this species of cockatoo is the destruction of their nests and their food. The cockatoo only eats tiny seeds found in Brown Stringybark,Desert Stringybark and Buloke. There has been significant clearing of Buloke trees by humans. Because the cockatoo prefers to eat the seeds of plants that are roughly 100 years old, planting crops now will not immediately help in the conservation of this species.

Dear Mr Environment Minister I am writing to you about the endangered south-eastern red-tailed black cockatoo. This species is endangered mainly because of reduction in their food. They feed nearly entirely on three types of trees: Brown Stringybark, Desert Stringybark and Buloke seeds. Roughly 97% of Bulokes have been cut down. Fires that burn in Stringybark forests reduce the availability of the seeds which is bad because the cockatoo feeds on the seeds. In addition to their food there aren’t enough eucalyptus trees that have hollows for the cockatoo to make nests. Another threat is their natural predator: the common brushtail possum. Helping to conserve this animal is hard mainly because it is so fussy; it only eats three types of plants and the Bulokes have to be roughly 100 years old. The best method is to plant all the Bulokes now. Then while the Bulokes are aging, all the cockatoos can be kept in enclosures that are free from any fires and from common brushtail possums. In the enclosures there should be water, a lot of Stringybark trees and eucalyptus trees with hollows that should allow them to make their nests. During the summer the trees should be heavily watered to stop them catching fires. In 100 years the Bulokes will be ready so then all the cockatoos can be released. Thankyou.
