The Gang-gang Cockatoo has a creaky, rising screech that sounds like a rusty hinge: ‘ky-or-ark’. The gang-gang cockatoo (Callocephalon fimbriatum ) is a parrot found in the cooler and wetter forests and woodlands of Australia, particularly alpine. Their average size is 34cm and their average weight is 257 grams. They can be located in food trees by the sounds of feeding and falling debris. Gang-gangs are gregarious but relatively quiet cockatoos. Young birds are similar to the adult female, with young males differing by having a red crown and forehead and a shorter, less twisted red crest. Females have extra yellow edging to their feathers that increases this barred effect. In both sexes, the feathers of the upperparts and wings are faintly edged pale grey, giving a barred appearance. The adult female has a dark grey head and crest, with the feathers of the underparts edged pink and yellow. The adult male has a distinctive scarlet red head and crest, with the rest of the body slate-grey. The Gang-gang Cockatoo is a small, stocky cockatoo with a wispy crest, large, broad wings and a short tail. After the breeding season has finished, and the days grow cooler and shorter, they undertake altitudinal movements, leaving the mountains and flying to lower elevations to spend the autumn and winter, where they often inhabit suburban gardens of lowland towns and cities. It is the only species placed in the genus Callocephalon. In the summer months, they are mostly found at higher elevations, where they breed in tree hollows in the moist eucalyptus forests of the mountainous Great Divide. The gang-gang cockatoo ( Callocephalon fimbriatum) is a parrot found in the cooler and wetter forests and woodlands of Australia, particularly alpine bushland.

The Gang-gang Cockatoo can be seen throughout many parts of south-eastern Australia.
