Males have a distinct scarlet red head and slate-grey body with white bars on it. Pairs prefer to nest in proximity to other pairs, rather than in isolation.īelow are four examples of potential Glossy Black-Cockatoo nest hollows in coastal forests of the Atlas of Life region.Other names Description Similar species Behaviour Diet Calls Reproduction Distribution/habitat References External links Projects Gang-gang Cockatoo Scientific name Callocephalon fimbriatum Bird family cockatoos Status Endangered (EN) Listen to audio The Gang-gang Cockatoo is gregarious in nature. The birds favour nesting sites where there are numerous suitable hollows. Storm, insect and (some) fire damage are important factors in creating hollows. Nest trees are usually either dead or damaged. As an indication, trunk 'diameter at breast height' (DBH in images below) of at least 60cm. Nest trees are usually large and very old eucalypts. Hollow in a 'spout' that is either vertical or no more than 45 degrees off verticalĮntrance diameter of at least 15cm, in a branch or trunk of at least 30cm diameter.Įntrance at least 8m above the ground, in the upper part of the trunk or in large, broken branches close to the main trunk Studies in central NSW have shown that Glossy Blacks in the Goonoo State Forest select nesting sites with the following features: Glossy Black-Cockatoos nest in tree hollows. Protecting suitable nest sites is critical to saving this species. The Threatened Species unit is particularly keen to identify trees which could be nesting sites for Glossy Black-Cockatoos. Photograph the cones AND the tree, and record this as a sighting on iNaturalist. This is a typical feed tree species for Glossy Black-Cockatoos across the Atlas of Life region. The images below show the chewed cones, alongside intact cones, of Allocasuarina littoralis. These small 'cones' are exceptionally tough, and if you find them torn apart in this way, you can be confident that Glossies have been feeding in the tree above. The tell-tale traces of recent feeding are the scattering of torn Allocasuarina cones. The Gang-gang Cockatoo is a small, overall dark grey cockatoo, with dull white edges on the wings and most of the body, with a short, square tail. Identifying where Glossy Black-Cockatoos feed and nest is potentially even more valuable than sightings of the birds themselves. "active member of Far South Coast Birdwatchers for many years"). Also, please note your level of experience (e.g. We simply ask that in the comments field you describe what you based your identification on, including how you excluded similar, candidate species. If you are confident in your identification, please go ahead and add a sighting to iNaturalist. We recognise, however, that many experienced 'birders' are able to confidently identify a bird based on sight or call alone. Most iNaturalist sightings require a photograph. RECORDING A SIGHTING WITHOUT A PHOTO - FOR EXPERIENCED BIRD WATCHERS 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. the scattering of torn Allocasuarina fruit on the forest floor is quite diagnostic. Such feasting also leaves tell-tale evidence long after they've gone. In fact the squeaking and cracking of their feeding is often the first indication of their presence. Small groups will sit quietly, chewing on the fruit, sometimes remaining in the same tree for hours. Glossy Blacks feed almost exclusively on Allocasuarina fruit (often called 'she-oak cones'). Soft, wavering call in flight - again, very different to the Yellow-tailed black call. Short tail, clearly shorter than Yellow-tailed blacks when seen in flight. Males have bright red panels in their tails, while females and juveniles have orange-red panels with varying amounts of black barring.įemales have variable amounts of yellow on the head and neck. considerably smaller than Yellow-tailed blacks.
