We are also interested in what they are feeding on. Try to photograph the birds - even an image from a distance may be sufficient to confirm the identification. The location, the number of birds (including sex & age - adult/juvenile - if apparent), and their behaviour at the time. We are mapping the distribution of Gang-gang cockatoos, the location and activity around suitable nest hollows and their feeding habits. Help to map these special birds and their habitats by recording sightings anywhere across south-eastern NSW & the ACT ![]() It is already listed as vulnerable in NSW. The Gang-gang CockatoO ( Callocephalon fimbriatum) is about to be listed as one of the more threatened species of cockatoo in Australia. Michael Mulvaney and Stacey Taylor presenting the Gang-gang research Here is the recording of the 2021 Science Week presentation about the findings to date from this Gang-gang nesting research project in ACT. There are different levels and kinds of contribution you can offer, from making observations, putting out motion sensitive cameras and recording what’s in tree hollows, to helping to ID the birds and their feed trees and analysing motion sensitive camera images. We will be gathering information about Gang-gangs that is currently unknown and co-ordinating our research with work undertaken elsewhere across the Cockatoo’s range, so that results in our area can be compared with that of other places and habitat such as burnt/unburnt urban/remote, using data from several different locations. This information will help inform the conservation of this bird and lead to the implementation of action as to how its dramatic decline (around 70% in less than 30 years) may be turned around. We are looking for people who want to find out more about Gang-gangs on the south coast, particularly what they are eating, where they are nesting, the rate of nesting success and how that success is influenced by factors thought to be impacting negatively on the Gang-gang such as brush-tail possum predation, hollow competition from Sulphur Crested Cockatoos and other species, overheating in hollows and flooding of hollows. Information on the musters can be found at the Canberra Ornithologists Group website.This project follows and extends successful research carried out in the ACT. Even if you don't see any birds, these reports are really important for the survey," he said. "Choose somewhere you spend a little time most days of the week, like your home garden or the local park, and record the maximum number you see or hear each day. Mr Davey said the quarterly gang-gang muster was a simple bird-watching activity that anyone could take part in. In spring the birds were most often recorded in suburbs adjoining forested habitats on Mt Majura, Mt Ainslie, Red Hill, Black Mountain and Mt Taylor. Surveys from home gardens, local parksĪs well as quarterly muster events like the one happening this week, the group has a separate year-long tracking project. It is part of the logos of both Canberra Ornithologists Group and ACT Parks, Conservation and Lands. ![]() The gang-gang is listed as vulnerable in NSW but is common in the ACT. "We're busily confirming the locations of them at the moment, but in general there seems to be a restricted distribution around the urban areas." "So far we've got about 4,000 records, which have all got to be looked at," he said. Mr Davey said there had been a good response and the resulting information could inform conservation plans such as protection of suburban nesting trees. The surveys are simple to complete and can be done online or by mail. It's important for this survey to also, if possible, record nil observations," he said. "The survey is based on your garden or on your worksite and what you do is record the maximum number of gang-gangs you see each day within a hundred metres of that spot. The group's Chris Davey said it was part of ongoing efforts to fill in knowledge gaps about their breeding and nesting habits. ![]() ![]() The Canberra Ornithologists Group is currently mapping the regional distribution of the cockatoos and the group is partway through a week-long muster to gather data from the community. Hundreds of Canberrans are doing their part this week to map the distribution of the ACT's well known gang-gang cockatoos.
