White Cockatoo or "Sulphur-crest" for short, Sulphur-crested Cockatoos are widespread throughout northern and eastern Australia and Tasmania and also New Guinea - introduced to south-western W.A. and New Zealand. They occur in a broad range of habitats ranging from coastal rainforest through to inland mallee but always where there are mature trees big enough to provide a large nest hollow.

Sulphur-crests are a popular cage bird and amuse some people because of their ability to mimic human speech - they are also very long lived. One such famous individual was "Cocky Bennett" from Tom Ugly's Point in Sydney who lived to the age of 116 and in his final 20 years was featherless - his favourite phrase was " One more feather and I'll fly".

There are two subspecies in Australia - the slightly smaller one in the north is rather more solitary and doesn't form the large flocks so familiar in the south. In farming areas, they can be a pest in crops and eat a wide variety of seed, usually on the ground, but they also feed on native fruits and berries in shrubs and trees.
