The Glossy Black-Cockatoo is the smallest of the five black-cockatoos. It has a brown-black head, neck and underparts, with red or orange-red tail panels and an otherwise dull black body. The crest is small and inconspicuous and the bill is broad and bulbous. Adult females have extensive yellow patches on the head and neck and the tail panels tend to be more orange-red with black bars, but may become less barred and more red with age. Some adult males have a few yellow feathers on the head and the males' tail panels tend to be bright red. Young birds resemble adult males but have yellow spotted or streaked breasts, bellies and flanks, with some yellow spots on cheeks and sides of head. They nest in tree hollows for breeding. The Glossy Black-Cockatoo feeds almost exclusively on the seeds of the Casuarina tree: in a particular area, birds may feed only on a single species. It may also sometimes eat wood-boring larvae. They strip the seed pods from the tree, then tear them open with their strong bills to extract the seeds — the ground below is often littered with dozens of discarded cones. They feed in threes, less commonly in pairs or small groups or in large flocks of up to 60 birds. Tame and easily approached when feeding, they can be detected by the clicking of their bills and the falling debris of casuarina cones and twigs. They mate for life, with pairs maintaining their bond all year round. The female prepares the nest hollow and incubates the eggs, only leaving the nest to feed herself after the newly hatched nestling is a week old. Males feed the female and nestling throughout the incubation and brooding period. Once fledged, the young bird is fed by both parents for up to four months and remains with them until the next breeding season.(Source: Birdlife Australia, n.d.), (Image: Don VanPoppel).
