![]() They would fly from Byles Creek Valley through to Copeland Road East and we assumed then off to Lane Cove National Park,” Ms Brown said. “After moving into Malton Road Beecroft in 2011 we would see Gang-gangs most weeks. Ms Smith has been instrumental in documenting and monitoring the species for the past four decades according to the organisation’s President, Ms Patricia Brown. The Gang-gang Cockatoo is the emblem of the Byles Creek Valley Union Inc which was started in the 1980s by Ms Robyn Smith to fight development in the wildlife corridor. Pairs share parental duties including nest preparation, incubating and caring for young after fledging. Like Powerful Owls, Ganggangs form close monogamous pairs and need mature trees for breeding. ![]() Similar to many cockatoos, they are often left-handed! Their diet consists of seeds, berries, fruits and nuts from native and introduced trees and shrubs as well as insects and their larvae. They are relatively quiet, compared to the screeching Sulphur-crested Cockatoo, sounding like a creaky gate or a cork being pulled from a bottle. They are sometimes mistaken as a Galah in flight. Females have a dark grey head and wispy crest. ![]() The adult male Gang-gang is a show-stopper recognised by its scarlet red head and crest with a slate grey body and wings. This is one of the last known breeding grounds in metropolitan Sydney, with the Byles Creek Valley wildlife corridor representing a stronghold and providing suitable habitat with large tree hollows. In 2013, only 14 birds were recorded in the Hornsby LGA. Clearing for farmland, residential releases and infrastructure resulted in numbers dropping significantly according to the NSW Scientific Committee. The population once extended across Baulkham Hills, Castle Hill, Cherrybrook and Dural. Hornsby and Ku-ring-gai Local Government Areas, the Gang-gang Cockatoo (Callocephalon fimbriatum) was listed as locally endangered under the Threatened Species Conservation Act. Key management sites for this threatened species are being identified by the NSW Government and other program partners, where feasible, cost-effective and beneficial management actions can be undertaken.Ĭurrently, no management sites have been identified for this threatened species.Adult female Gang-gang Cockatoo © Patricia Brown Liaise with land managers and landholders managing fire to raise awareness about the importance of live and standing dead hollow-bearing trees, and to minimise losses of these trees when carrying out prescribed burns. Care must be taken to ensure that the removal of exotic berry-bearing shrubs and trees such as cotoneatser, hawthorn and pyracantha, that provide foraging habitat, is compensated for by planting of appropriate native foraging plant species such as acacias and eucalypts. Restore gang-gang cockatoo habitat in strategic locations close to known habitat and movement corridors, using appropriate local tree, shrub and ground cover species. Where possible, negotiate management agreements with landholders that are funded in perpetuity that allows ongoing recruitment of native local trees, shrubs and grasses. Protect known and potential remnant gang-gang cockatoo habitat, particularly tall wet forest and dry sclerophyll forest vegetation communities with large trees supporting hollows that are 10cm in diameter or larger and manage these areas to allow ongoing regeneration of local native trees, shrubs and ground layer plants. The actions listed in the action toolbox are supplementary to NSW legislation, policy and programs and can be used by stakeholders, where applicable to guide management at a site, regional or state scale. Threats to this species are outlined here. Many of these threats are addressed by NSW planning, native vegetation, and biodiversity legislation, policy and programs including the offsets program (BioBanking, NSW Biodiversity Offsets Policy for Major Projects), Biodiversity Certification, management of environmental water and reservation under the National Parks and Wildlife Act 1974. The key threats to the viability of landscape-managed species are loss, fragmentation and degradation of habitat, and widespread pervasive factors such as impacts of climate change and disease. Proportion of the species' distribution on reserveĥ4% of the species' distribution occurs on reserve (within NSW National Parks and Wildlife Service estate).
