Galahs have a grey back, a pale grey rump, a pink face and chest, and a light pink crest. The male has a very dark brown iris, and the female has a mid-brown/red iris. They move in large noisy flocks and congregate to roost together at night.
The first European settlers in this area rarely saw galahs but this colourful cockatoo is now one of the most abundant and familiar parrots. They hacve adapted to eat cereal crops and other introduced species. Their preference for the seeds of cultivated crops makes them a pest in agricultural areas. The sight of these birds clowning around performing acrobatics on powerlines is very comical. They feed mainly on seeds. They are also a popular visitor to the feeding tables that some people erect.
