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).

C. s. gymnopis has darker blue eye-rings, more strongly marked pink lores and a yellow wash to the lower-ear coverts.

[2] 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 are considered to be crop pests,[9] and can be destructive to the trees in which they perch, by chewing the bark off smaller twigs.

They generally roost in trees overnight, and fly off to feed in the early morning before returning in the late evening.

[citation needed] The call consists of high pitched notes and screeches somewhat similar to the sulfur-crested cockatoo.

[10] In July 2019, in a scene that was said to resemble a "horror movie",[11][12] about 60 corellas in Adelaide, South Australia,[13] died in a suspected case of poisoning, after "falling from the sky", bleeding from their mouths, and wailing.
