Galah
Eolophus roseicapilla
The galah is about 35 cm (14 in) in length, and weighs 270–350 g (10–12 oz). It has a pale silver to grey back, a pale grey rump, a pink face and breast, and a light pink mobile crest. It has a bone-coloured beak, and the bare skin of the eye ring is carunculated. It has grey legs. The sexes appear similar; however, adult birds differ in the colour of the irises; the male has very dark brown (almost black) irises and the female has mid-brown or red irises. Adults are more brightly coloured than juveniles.

Little Corella
Cacatua sanguinea
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. transfreta are a little smaller than the nominate form. C. s. Voice: The call consists of high pitched notes and screeches somewhat similar to the sulphur-crested cockatoo. Large flocks will call simultaneously and can create a deafening screeching sound audible from several kilometers away.
