These can be divided into two main groups the white cockatoos and the black cockatoos. Gang-gangs are very social birds, but not overly noisy. Cockatoos (family Cacatuidae) Native to Australia, Papua New Guinea and Indonesia, there are over 40 species. The birds are not easily mistaken for other cockatoos, but while in flight may resemble the Galah. Juvenile males can be distinguished by their brighter crowns and shorter crests, but otherwise look similar to the adult female. The edges of feathers on upperarts are slightly paler grey than the rest of the feather, which makes the bird look somewhat barred. The edges of feathers in underparts have edges of yellow or pink. The head and crest is bright red in males, but dark grey in females. The gang-gang cockatoo is a grey bird with a wispy crest. Some cockatoo species have been adversely affected by habitat loss, particularly from a shortage suitable. The name gang-gang comes from a New South Wales Aboriginal language, probably from one of the coastal languages, although possibly from Wiradjuri. Cockatoos are monogamous and nest in tree hollows. 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. The gang-gang cockatoo is the faunal emblem of the Australian Capital Territory. Smaller birds chase these predators out of their territories so that. It ranges throughout south-eastern Australia. Owls in particular elicit intense mobbing behavior, as they often prey on sleeping birds. Mostly mild grey in colour with some lighter scalloping (more pronounced and buffy in females), the male has a red head and crest, while the female has a small fluffy grey crest. Both sexes incubate the 2-3 eggs for about a month and care for the young. The female chooses a nest hollow in a suitable tree and both sexes prepare the nest for egg-laying, lining it with wood-chips and dust by chewing at the sides of the hollow. The ACT Environment Minister says the move provides a chance to focus. Gang-gang Cockatoos form close, monogamous pairs. The parrots have been impacted by climate change and bushfires. It is the only species placed in the genus Callocephalon. The gang-gang cockatoo will be added to the threatened list. The gang-gang cockatoo (Callocephalon fimbriatum) is a parrot found in the cooler and wetter forests and woodlands of Australia, particularly alpine bushland.
