Yellow-tailed Black-Cockatoos were once content to feed on the seeds of native shrubs and trees, especially banksias, hakeas and casuarinas, as well as extracting the insect larvae that bore into the branches of wattles. Now, after the establishment of extensive plantations of exotic Monterey Pines, the cockatoos may feed more often by tearing open pine cones to extract the seeds. The population on South Australia’s Eyre Peninsula is now reliant on the seeds of the Aleppo Pine, a noxious weed, as its preferred habitat, Sugar Gum woodlands, has become extensively fragmented.
Research featured in the ‘State of Australia’s Birds 2015‘ headline and regional reports indicates a significant decline for the Yellow-tailed Black Cockatoo (and some other parrot species) in the East Coast.
The Yellow-tailed Black-Cockatoo is a large cockatoo. It is easily identified by its mostly black plumage, with most body feathers edged with yellow, not visible at a distance. It has a yellow cheek patch and yellow panels on the tail. The female has a larger yellow cheek patch, pale grey eye-ring (pink in males), white upper bill (grey-black in males) and black marks in the yellow tail panels. Young birds resemble the adult female, but young males have a smaller cheek patch.
The contact call is a drawn-out “kee-ow”. Some screeches are also given.
The Yellow-tailed Black-Cockatoo is found in south-eastern Australia, from Eyre Peninsula, South Australia to south and central eastern Queensland.
Habitat: Woodland, Forest
The Yellow-tailed Black-Cockatoo inhabits a variety of habitat types, but favours eucalypt woodland and pine plantations. Small to large flocks can be seen in these areas, either perched or flying on slowly flapping wings.
The Yellow-Tailed Black-Cockatoo is one of six species of Black-Cockatoo in Australia. In recent years it has been in rapid decline because of native habitat clearance, with a loss of food supply and nest sites.
Yellow-tailed Black-Cockatoos feed in small to large, noisy flocks. The favoured food is seeds of native trees and pinecones, but birds also feed on the seeds of ground plants. Some insects are also eaten.
Yellow-tailed Black-Cockatoos have a long breeding season, which varies throughout their range. Both sexes construct the nest, which is a large tree hollow, lined with wood chips. The female alone incubates the eggs, while the male supplies her with food. Usually only one chick survives, and this will stay in the care of its parents for about six months.
