Immature / young birds look like adults, but have a shorter bill and their periophthalmic ring is less blue. Males and females look alike, except males tend to be larger than females and have larger heads and beaks.
They have dark brown irides (= plural of iris) and grey feet. The narrow periophthalmic ring is bluish-grey, extending to the upper cheeks. The bill is greyish-horn color and elongated. The underside of the tail-feathers and wings are washed with yellow. The ear-coverts and feathers above the eyes are tinged dusky-yellow. The lores (the region between the eye and bill on the side of a bird’s head) and base of the feathers to the head, nape (back of the neck), breast and back are orange-pink. The general plumage is white with a very short broad crest. They can live 50 years or longer however, most succumb to accidents or disease. It mostly feeds on the ground, eating seeds including cereal crops such as wheat and barley. These cockatoos generally roosts in trees overnight, and fly off to feed in the early morning with an almost deafening screeching. The Little Corella congregates in flocks of up to several thousand birds, which often include many Galahs. It is so common in its natural habitat that it has become something of a pest throughout much of Australia, as it can be destructive to the trees in which it perches by chewing the bark off smaller twigs.
The Little Corella, Cacatua sanguinea – sometimes referred to as the bare-eyed cockatoo – is endemic to Eastern, North-western and Northern Australia.
