The female has distinctive yellow patches on the head and neck and paler, more orange-red tail panels barred with black. Males are black with a brownish head and front with solid red panels in their tail. The plumage is black with yellow edges and yellow panels on the tail. Glossy Black Cockatoo (Calyptorhynchus lathami) The Glossy Black Cockatoo is the smallest of the Calyptorhynchus genus at around 45cm to 50cm. These species are blackish brown in color with yellow spots on their cheeks. He has written on all aspects of natural history, advised the ACT Government on biodiversity and published multiple guides to the region’s flora and fauna. A yellow-tailed black cockatoo is a large cockatoo that belongs to the parrot family. Ian Fraser is a Canberra naturalist, conservationist and author. Raucously begging youngsters often accompany the flocks, but they may have come from as far away as Victoria or the NSW north coast – our knowledge of their movements is sketchy.Īs far as I am aware there is only one breeding record from the ACT, a historic one and, tragically, from a tree cut down in the ranges in days long before the protection of Namadgi National Park.įor now, however, the black cockies are very much a part of our lives. It remains to be seen what effect the calamitous fires of the summer just gone might have on the ability of the cockies to reproduce. The end result, which may take some time to achieve, is a fat wriggling protein prize.Ī hollow suitable for black cocky breeding is only found in mountain eucalypts at least 200 years old. So far it has been using its tail as a prop, but now it needs a firmer platform, so it chews and hauls a strip of timber out to a 45-degree angle and stands on it while it excavates with its great tool of a bill. The bird inspects the trunk to identify the holes through which the industrious grub ejects its sawdust droppings (‘frass’). For the wattles, they just bite into the soft trunk to see if it’s hollow, then rip straight into it.Įucalypt timber, however, is a very different proposition. They are all mostly black in colour, and the taxa may be differentiated partly by size and partly by small areas of red, grey. RM 2A2M52D Calyptorhynchus galeatus, Print, Described by French naturalist Anselme Gatan Desmarest in 1826, the genus Calyptorhynchus has five species of cockatoos. The grub-seeking cocky, usually part of a loose flock, has different strategies for the softer wattles and the hard eucalypts. RF 2C93MMC Yellow Tailed Black Cockatoos. ![]() (That’s a story in itself, but one for another day.) ![]() They have a particular fondness for the big white grubs, like pale sausages, of cossid moths which chew through the solid wood of wattle and eucalypt trees. However, they have another, very different food preference which also relies on the mighty bills. We always know when they’re visiting even without the quiet ‘wee-oo’ contact calls, as the discarded cones crash onto our little balcony. They easily crush the tough woody banksia cones, having nipped through the stem, and extract the seeds. To watch them feeding – when they can often become absorbed in the task and allow us to watch – is first to be reminded of just how big they are, a good 60 cm long with massively powerful bills.
