![]() ![]() have a call that sound like a creaking gate, or a cork being pulled from a bottle.often return to the same nesting tree each year.In combination these factors present a serious threat to Gang-gang Cockatoos in the medium and long term. This species is also susceptible to psittacine circovirus disease which causes feather loss and beak abnormalities. "active member of Far South Coast Birdwatchers for many years").Īll sightings are recorded using the NatureMapr database.Land clearing and the removal of old trees endangers Gang-gang Cockatoos because they lose their feeding habitat and breeding hollows. 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 NatureMapr. We recognise, however, that many experienced 'birders' are able to confidently identify a bird based on sight or call alone. Most NatureMapr sightings require a photograph. Please add this to your sighting! Recording a sighting without a photo - for experienced bird watchers For Glossy Black-Cockatoos, if you see them using or investigating a tree hollow, this is very important information. Remember that we are keen to record any species of cockatoo, not only the Glossy Black-Cockatoos. Try to get a photo of the birds, but if this is not possible or if they have moved on, photograph evidence of their feeding and of the feed tree. The location, the number of birds (including sex & age - adult/juvenile - if apparent), their behaviour and - if feeding - what type of trees they are using. And juveniles sit begging - constantly and loudly – making no apparent attempt to feed for themselves. Feeding birds may be at any level in the vegetation, even at ground level. This apparently destructive behaviour is due to their determined searching for wood-boring grubs of moths or beetles.Ī feeding flock often involves some birds sitting high in the trees, calling an alarm if approached. They are also famous for tearing into the bark and branches of various trees, often dropping branches or snapping small saplings. For example, they take the woody fruit of Eucalyptus, Hakea, Banksia and a variety of introduced trees, including plantation pine trees. ![]() They feed in a wide variety of trees and may be found in woodland, parks, coastal heath or forest. In flight their long-tails, dark colour, and loud calls are distinctive. Yellow-tailed Black-Cockatoos may be seen flying in small or large flocks. Where to look for Yellow-tailed Black-Cockatoos: Juveniles have colouration like female, but are best recognised by their continual, rasping begging calls. Yellow cheek patch, larger and brighter in adult female than in the male. Pale yellow tail panels, variously mottled with black in both males and females. Large, slender bird with long tail and long wings. Some features to look for in recognising Yellow-tailed Black-Cockatoos: 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'). Where to look for Glossy Black-Cockatoos: 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.
