Cacatua sanguinea

The little corella (Cacatua sanguinea ), also known as the short-billed corella, bare-eyed cockatoo, blood-stained cockatoo, and little cockatoo is a white cockatoo native to Australia and southern New Guinea. It was known as Birdirra among the Yindjibarndi people of the central and western Pilbara. They would keep them as pets, or traditionally cook and eat them. The downy feathers are used in traditional ceremonies and dances where they adorn head and armbands.


The little corella is a small white cockatoo growing to 35–41 cm (14–16 in) in length and weighs 370–630 g (13–22 oz), with a mean weight of 525 g (1.157 lb). It is similar in appearance to both the long-billed corella and the western corella, but the little corella is smaller, and unlike either of those species, it has upper and lower mandibles of similar length. It is easily distinguished from the long-billed corella by the lack of an orange throat bar. C. s. normantoni and C. s. normantoni are a little smaller than the nominate form. C. s. normantoni is lightly brownish on the underside of flight and tail feathers. C. s. gymnopis has darker blue eye-rings, more strongly marked pink lores and a yellow wash to the lower-ear coverts. Females are slightly smaller than males in weight, wing length, culmen size, tarsus length, tail length and eye ring diameter.



The nominate form, C. s. sanguinea is found in Northern Australia. C. s. normantoni is found on the Western Cape York Peninsula. C. s. transfreta is found in New Guinea. C. s. gymnopis is found in Central, Eastern, and South-eastern Australia. Habitat ranges from the arid deserts of central Australia to the eastern coastal plains, but they are not found in thick forests. Little corellas can also be found in urban areas, including Melbourne, Canberra, Sydney and Brisbane, where they feed on lawns and playing fields. They are numerous in farmlands throughout New South Wales and Queensland, and have become so common in some areas that they have become something of a pest, and can be destructive to the trees in which they perch, by chewing the bark off smaller twigs.

Habits and Lifestyle

Little corellas congregate in flocks of up to several thousand, which often include other birds such as galahs, sulfur-crested cockatoos and red-tailed black cockatoos. They generally roost in trees overnight, and fly off to feed in the early morning before returning in the late evening. Flocks will often fly many kilometers between their feeding and roosting areas, and in desert areas must also fly to watering holes twice a day, while corellas which live in coastal areas do not have to fly long distances to find water.

Diet and Nutrition

Little corellas usually feed on the ground, however occasionally feed in trees and shrubs. They eat a variety of both wild and cultivated seeds and regularly feed on lawn grasses in urban areas. They frequently feed on cereal crops such as wheat, barley and maize and can become a considerable agricultural pest in some areas.

Mating Habits

Breeding occurs from May to October, and usually takes place earlier in the north of its range. The nest is usually in a tree hollow, cliff cavity or termite mound.


Population threats

In July 2019, in a scene that was said to resemble a "horror movie", about 60 corellas in Adelaide, South Australia, died in a suspected case of poisoning, after "falling from the sky", bleeding from their mouths, and wailing. At least 57 of the birds were long-billed corellas, with a few of them being were short-billed corellas. It was hoped that whoever poisoned them would get traced after doing a report on toxicology, which could nevertheless take several weeks to complete, because in Australia, people were required to register if they purchase poisons, according to Sarah King, founder of Casper's Bird Rescue, who witnessed the deaths, and also said that the type of poison was a slow one that takes several weeks to work. Additionally, the local Alexandrina council had beforehand called for short-billed corellas to be culled for damaging crops and chewing on streetlights, damaging built infrastructure such as buildings and sporting equipment, and displacing other native species of birds and bees, possums, and other organisms.
