Distribution and Habitat
The Yellow-tailed Black Cockatoo is found up to 2000 m (6500 ft) AMSL over southeastern Australia including the island of Tasmania and the islands of the Bass Strait (King, Flinders, Cape Barren islands), and also on Kangaroo Island. On Tasmania and the islands of the Bass Strait it is the only native black-coloured cockatoo. On the mainland, it is found from the vicinity of Gin Gin and Gympie in south and central eastern Queensland, south through New South Wales, where it occurs along the Great Dividing Range and to the coast, and into and across most of Victoria bar the northern and northwestern corner, to the Coorong and Mount Lofty Ranges in southeastern South Australia. A tiny population numbering 30 to 40 birds inhabits the Eyre Peninsula. There they are found in Sugar Gum (Eucalyptus cladocalyx) woodland in the lower peninsula and migrate to the mallee areas in the northern peninsula after breeding. There is evidence that birds on the New South Wales south coast move from elevated areas to lower lying areas towards the coast in winter. They are generally common or locally very common in a wide range of habits, although they tend to be locally rare at the limits of their range. Their breeding range is restricted to areas with large old trees.
The birds may be found in a variety of habitats including grassy woodland, riparian forest, heathland, subalpine areas, pine plantations, and occasionally in urban areas, as long as there is a plentiful food supply. They have also spread to parts of suburban Sydney, particularly on or near golf courses, pine plantations and parks, such as Centennial Park in the eastern suburbs. It is unclear whether this is adaptive or because of loss of habitat elsewhere. In urban Melbourne, they have been recorded at Yarra Bend Park. The so-called "Black Saturday bushfires" in 2009 appear to have caused sufficient loss of their natural habitat for them to have been sighted in other parts if the urban areas of Melbourne as well.

Famous quotes containing the words distribution and/or habitat:
“In this distribution of functions, the scholar is the delegated intellect. In the right state, he is, Man Thinking. In the degenerate state, when the victim of society, he tends to become a mere thinker, or, still worse, the parrot of other men’s thinking.”
—Ralph Waldo Emerson (1803–1882)
“Nature is the mother and the habitat of man, even if sometimes a stepmother and an unfriendly home.”
—John Dewey (1859–1952)
