The Gang-gang Cockatoo (Callocephalon fimbriatum) is one of Australia's most endearing parrots and the formal avian emblem of the Australian Capital Territory. Despite this distinction it is now classified as Endangered, with the 2019–20 Black Summer bushfires burning through an estimated 70–80% of its core breeding range in Victoria and NSW.
Gang-gangs are medium-sized, stocky cockatoos with a scalloped grey plumage that gives them an almost knitted appearance. Males are immediately identified by their striking red heads and crests; females are grey with a faint green wash and orange-edged feathers on the belly. Both sexes have the distinctive creaking, rusty-hinge call that carries clearly through mountain forest.
During spring and summer, Gang-gangs breed in the tall mountain ash and alpine ash forests of the Victorian and NSW ranges, nesting in large hollows in mature eucalypts. In autumn and winter, they move to lower altitudes — often appearing in suburban parks and gardens in Canberra, the Dandenong Ranges, and alpine fringe towns like Bright and Harrietville.
Post-fire recovery is complicated by the loss of hollow-bearing trees. Gang-gangs need old trees with large hollows for nesting, and the fires destroyed many of these. Conservation programs are now installing nest boxes in recovering forest as a stopgap measure.
Winter visits to Canberra's suburbs or the Dandenong Ranges east of Melbourne offer some of the most reliable encounters — birds regularly feed on berry-producing ornamental trees in gardens and street plantings.
Best places to see the Gang-gang Cockatoo
Dandenong Ranges (Belgrave, Sherbrooke)
VICExcellent habitat for Gang-gangs year-round. Sherbrooke Forest and surrounding suburbs see frequent sightings. Often found alongside Superb Lyrebirds.
Canberra suburbs (winter)
ACTGang-gangs descend from the ranges to feed on berry-producing trees in suburban Canberra gardens April–August. Check ornamental hawthorns, cotoneasters, and berry-bearing natives.
Alpine Victoria (Bright, Mount Hotham area)
VICBreeding habitat in mountain ash forest. Good in spring and early summer before birds descend.
Tharwa Valley / Namadgi National Park
ACTMontane forest and alpine ash. One of the most reliable year-round sites after the fires.
