Distribution and Habitat
Unlike the Galah, Major Mitchell's Cockatoo has declined rather than increased as a result of man-made changes to the arid interior of Australia. Where Galahs readily occupy cleared and part-cleared land, Major Mitchell's Cockatoo requires extensive woodlands, particularly favouring Callitris, Allocasuarina and Eucalyptus. In contrast to other cockatoos, Major Mitchell pairs will not nest close to one another; in consequence, they cannot tolerate fragmented, partly cleared habitats, and their range is contracting.
In the Mallee region of Victoria where the Galah and Major Mitchell's Cockatoo can be found to be nesting in the same area, there has been on occasion where the two species have interbred and produced hybridised offspring

Famous quotes containing the words distribution and/or habitat:
“The question for the country now is how to secure a more equal distribution of property among the people. There can be no republican institutions with vast masses of property permanently in a few hands, and large masses of voters without property.... Let no man get by inheritance, or by will, more than will produce at four per cent interest an income ... of fifteen thousand dollars] per year, or an estate of five hundred thousand dollars.”
—Rutherford Birchard Hayes (1822–1893)
“Neither moral relations nor the moral law can swing in vacuo. Their only habitat can be a mind which feels them; and no world composed of merely physical facts can possibly be a world to which ethical propositions apply.”
—William James (1842–1910)
