It appears to have benefited from the change in the landscape since European colonisation and may be replacing the Major Mitchell's cockatoo in parts of its range. The term galah is derived from gilaa, a word found in Yuwaalaraay and neighbouring Aboriginal languages.
Galahs are about 35 cm long and weigh 270–350 g. They have a pale grey to mid-grey back, a pale grey rump, a pink face and chest, and a light pink mobile crest. They have a bone-coloured beak and the bare skin of the eye rings is carunculated. They have grey legs. The genders appear similar, however generally 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. The colours of the juveniles are duller than the adults. Juveniles have greyish chests, crowns, and crests, and they have brown irises and whitish bare eye rings, which are not carunculated.
