The Gang-gang Cockatoo, Callocephalon fimbriatum, is found in the cooler and wetter forests and woodlands of Australia, particularly alpine bush land. It ranges throughout south-eastern Australia and Tasmania.
Mostly mid gray in colour, the male has a red head and crest, while the female has a small fluffy gray crest. It is easily identified by its distinctive call, which is described as resembling a creaky gate, or the sound of a cork being pulled from a wine bottle.
Like all cockatoos, Gang-gangs nest in hollow trees. Loss of older, hollow-bearing trees and loss of feeding habitat across south-eastern Australia through land clearing has led to a significant reduction in the numbers of this cockatoo in recent years.
