Birds have been observed nesting in hollows in large, old trees, and breeding has been documented at least since 1994. The maximum population is estimated to be between 18 and 40 pairs. Individual birds are likely on occasion to move across the population boundary.ĥ. The population encompasses, but is not restricted to, Pennant Hills Park and parts of Lane Cove National Park. This population is bounded by Beecroft - Cheltenham in the west, Epping - North Epping in the south, Turramurra - South Turramurra in the east, and Thornleigh - Wahroonga to the north. A population of Gang-gang Cockatoos persists in the Hornsby and Ku-ring-gai Local Government Areas. Gang-gang Cockatoos were once widespread and numerous in Sydney and surrounding areas, but have been greatly reduced in recent years by loss of habitat.Ĥ. The species occurs in a variety of forest and woodland habitats and occasionally in more open areas in south-eastern New South Wales and Victoria.ģ. Both sexes have crests the male is distinguished from the female by its bright red head. The Gang-gang Cockatoo is a relatively small, dark grey cockatoo. The Gang-gang Cockatoo, Callocephalon fimbriatum (Grant), is not listed as an Endangered Species on Part 1 of Schedule 1 of the Act, and thus populations of the Gang-gang Cockatoo are eligible for listing as endangered populations on Part 2 of Schedule 1 of the Act.Ģ.

Listing of Endangered Populations is provided for by Part 2 of the Act. The Scientific Committee, established by the Threatened Species Conservation Act, has made a Final Determination to list the Gang-gang Cockatoo, Callocephalon fimbriatum (Grant), population in the Hornsby and Ku-ring-gai Local Government Areas as an ENDANGERED POPULATION on Part 2 of Schedule 1 of the Act.

Researchers hope they will provide an opportunity to observe the behaviours of the Gang-gangs and help in their conservation.Gang-gang cockatoo (Callocephalon fimbriatum) population, Hornsby and Ku-ring-gai Local Government Areas - endangered population listing “The money is always scarce but this project has been very collaborative – researchers, government staff, citizen scientists and community groups,” Dr Rhind said.Ĭockatubes involve creating artificial breeding hollows around the Eurobodalla to attract the birds. One of those projects – “Cockatubes” – has been introduced by biologist Susan Rhind in conjunction with Eurobodalla Shire Council’s natural resources supervisor Courtney Fink-Downes. “Researchers are coordinating projects to secure the Gang-gang’s future.” So when we do, we measure everything we can,” Dr Rayner said. She said there was very limited data available when it came to Gang-gang breeding. Statistics show there’s been a 69 per cent decline in the species since the turn of the century.ĭr Rayner has been collecting data from natural Gang-gang nesting hollows around the capital region to determine if they are actually being used for breeding or not.
