| − | The Little Corella, Cacatua sanguinea, is a white cockatoo native to Australia; it is sometimes called the Bare-eyed cockatoo.

| − | The Little Corella grows to 36 to 39 cm in length and congregates in flocks of up to several thousand birds, which often include many Galahs.

| − | Little Corellas are mostly white, with a fleshy blue eye-ring and a pale rose-pink patch between the eye and bill. In flight, a bright sulphur-yellow wash can be seen on the underwing and under tail. The sexes are similar in plumage, and young birds look like the adults. The adults measure 35cm - 39cm; young birds are slightly smaller.

| − | Little Corellas are widespread throughout Australia, although large gaps separate some populations. Their range is expanding with land clearing and increased sources of water. Escaped or deliberately released cage birds have also helped Numbers in the east of Australia. The Little Corella is the most widely distributed of the three corella species found in Australia. The Western Corella is confined the extreme south-west of Western Australia, and the Long-billed Corella is found in the south-east.

| − | The bird generally roosts in trees overnight, and flies off to feed in the early morning with an almost deafening screeching. It mostly feeds on the ground, eating seeds including cereal crops such as wheat and barley. It is so common that it has become something of a pest throughout much of Australia, and can be destructive to the trees in which it perches, by chewing the bark off smaller twigs.
| + | Diet includes seeds of cereal crops such as wheat and barley. |
| − | Little Corellas feed in large noisy flocks. The birds feed mainly on the ground, and have to drink on a daily basis. The most common foods are grains and grass seeds, and the increase in agricultural crops has increased the birds' numbers in these areas where they may become pests. Some bulbs and fruits may also be eaten.

| − | Breeding
| |
| − | The Little Corella may breed at any time of the year when conditions are suitable. Birds are thought to pair for life and will start breeding at the start of a long period of rain. The nest site is a suitable tree hollow, lined with shavings of wood. This is normally used for several years in row. Both sexes incubate the two to four eggs and both care for the young chicks. The eggs hatch after about 25 days, and the chicks are born naked and totally dependent on their parents.

| | | | |
| − | Breeding pairs nest in large colonies, and several nests may be found in the same tree. Where their ranges overlap, different corella species may nest together, but they are not thought to breed with each other
| + | A nest is built in a suitable tree hollow, lined with shavings of wood. 2-4 eggs are laid and are incubated by both parents for about 25 days. |
