Gang gang cockatoo chibi4/11/2024 Outcomes from the assessment are not expected until early 2022, but you can see our submission in support of the listing here. It is for these reasons that Canberra’s favourite bird has recently been assessed for national listing in the endangered category. This is increasingly concerning when considering that the population has declined by approximately 69% in the previous three generations. It is estimated that the fires impacted the bird’s distribution by 28-36%, reduced the carrying capacity for the species by 40%, and resulted in a 10% reduction of the overall population. The species suffered enormously from the 2019/2020 bushfires in both mortality and habitat loss. Hollow competition isn’t the only threat to Gang-gang Cockatoo populations. Gang-gang Cockatoos being social birds, often form creches where several pairs will nest nearby to one another and share the burdens of parenthood. After the egg is laid, both parents will incubate it for 4-6 weeks until the fledgling hatches. Once the Gang-gangs have secured a hollow they will line it with wood chips and dust before egg-laying. Competition for nesting hollows is fierce as many species are looking for the same features including possums, Sulphur Crested Cockatoos, and Galahs. These requirements mean that the Gang-gang Cockatoos are ideally looking for hollows in mature trees.īut as most Canberrans will tell you, finding the perfect home in the current market is extremely difficult and, unfortunately, the bird world is no exception. They are very particular about the form and size of their nesting hollows requiring an average hollow depth of 50.5 cm, an average hollow entrance width of 13.1cm and height of 21.3cm, and the hollow height being approximately 7.5m above the ground. Like most young couples looking to start a family, the birds are touring the city’s best locations to find an appropriate nesting site. Currently, while the rest of us are twiddling our thumbs in lockdown, Canberra’s Gang-gang Cockatoos are busily heeding the arrival of Spring by preparing for their breeding season. Gang-gang Cockatoos are a popular feature of Canberra’s cooler months as they fly down from the surrounding mountains to take refuge from the winter chill in the city’s parks and reserves.
