Gang-gang Cockatoos are seen in pairs during the breeding season and in flocks of up to 100 at other times. Seasonal migration occurs in this species with populations peaking in Canberra suburbs from April to September. In summer, they migrate to the Brindabella ranges to breed. Preferred hollows are fairly high and vertical or steeply sloping, lined with wood chips chewed from hollow walls. Nests are built in tree hollows of tall trees close to permanent watercourses. Hatching occurs at 30 days and the young remain in the nest for about 8 weeks. Both the male and female take turns to incubate a clutch of 2 to 3 eggs.

The breeding season of Gang-gang Cockatoos lasts from October to January. Gang-gangs require old, hollow-bearing trees close to a permanent water supply. In winter, they are found in drier, more open woodlands and in urban areas. During the summer, they are prevalent in mountain woodlands containing eucalypts and acacias up to an altitude of 2000m. Gang-gang Cockatoos show seasonal migration. Pairs and small flocks were recorded throughout the survey area with highest detection frequencies in suburban Turner, CSIRO, ANU and NMA. Conservation (Pet/Pest) Status - NationalĬurrently not listed as a threatened species under the EPBC Act 1999, however it is considered a Protected Native Animal. Sightings in the urban Canberra have been slowly increasing over the last 20 years and population levels in the region are considered stable (COG). Over the last 20 years, the overall reporting rate in NSW has dropped by 44%. The Gang-gang Cockatoo is a protected native species in the ACT and are listed as a vulnerable species in NSW. Country of OriginĪustralia Conservation (Pet/Pest) Status - Regional They are most frequently encountered along the Cotter, Gudgenby and Naas River. Gang Gangs regularly inhabit the inner suburbs of Canberra, particularly those near Lake Burley Griffin, Black Mountain, Aranda and Mount Ainsle. Southeast Australia from eastern NSW to southern VIC. The Galah ( Eolophus roseicapilla) is classed in the same family and may look similar in flight, but can be recognised by its pink face and belly and pinkish-white crest, crown and forehead. The Gang-gang Cockatoo is quite unique in appearance. Species CallĪn unmistakable and prolonged, rusty, gate-like screech. The young resemble the adult female with the exception of a red crest and crown on young males. The female has grey and salmon pink bars on its under belly and while the tail is also dark grey, the base has greenish-yellow bars.

The base of the tail is washed in yellow and the tail is unbarred and dark grey. Males have a bright orange-red crest and head while females have a dark grey crest and head. They are predominantly grey bodied with a fine and wispy crest. Distinguishing Featuresīoth male and female Gang-gang Cockatoos have large pale grey bills, broad wings edged in white and a short tail. Gang-gang, Gang-gang CockatooRed-crowned Cockatoo, Redheaded Cockatoo, Helmeted Cockatoo, Red-crowned Parrot and Redheaded Parrot. Cat owners can prevent their pets preying on the species by installing a cat run or enclosure. An entrance diameter of 12cm and an inside diameter of 22cm is recommended.

A vertical nest box at least 10m above the ground can also provide good breeding shelter. The protection of remnant vegetation containing dead and mature trees is essential for protecting cockatoo populations. Several actions can help to protect the Gang-gang Cockatoo from decline. Threats/Control Methods - Localįree roaming domestic pets will attack young birds in their first few months of life. This disease is often fatal and is a contributing factor to the decline of populations across NSW.

The Gang Gang Cockatoo is also susceptible to the Psittacine circovirus disease (PCD) which causes feather, beak and skin abnormalities. Competition for the diminishing nest hollows occurs with other birds, such as the Common Myna ( Acridotheres tristis) and the Common Starling ( Sturnus vulgaris), and the Brush-tailed possum ( Trichosurus vulpecular). These losses occur through land clearing, frequent fires and habitat degradation. Loss of nesting hollows poses a significant threat to the successful breeding of Gang-gang Cockatoos.
