AppearanceGalahs 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 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.
NamingThree subspecies are usually recognised. There is slight variation in the colours of the plumage and in the extent of the carunculation of the eye rings among the three subspecies.
The south-eastern form, ''E. r. albiceps'', is clearly distinct from the paler-bodied Western Australian nominate subspecies, ''E. r. roseicapillus'', although the extent and nature of the central hybrid zone remains undefined. Most pet birds outside Australia are the south-eastern form.
The third form, ''E. r. kuhli'', found right across the northern part of the continent, tends to be a little smaller and is distinguished from ''albiceps'' by differences in the shape and colour of the crest, although its status as a valid subspecies is uncertain.* Gulargambone, New South Wales
DistributionGalahs are found in all Australian states, and are absent only from the driest areas and the far north of Cape York Peninsula. It is still uncertain whether they are native to Tasmania, though they are locally common today, especially in urban areas. They are common in some metropolitan areas, for example Adelaide, Perth and Melbourne, and common to abundant in open habitats which offer at least some scattered trees for shelter. The changes wrought by European settlement, a disaster for many species, have been highly beneficial for the galah because of the clearing of forests in fertile areas and the provision of stock watering points in arid zones.
Flocks of galahs will often congregate and forage on foot for food in open grassy areas.
ReproductionThe Galah nests in tree cavities. The eggs are white and there are usually two or five in a clutch. The eggs are incubated for about 25 days, and both the male and female share the incubation. The chicks leave the nest about 49 days after hatching.
Like most other cockatoos, Galahs create strong lifelong bonds with their partners.
Cultural"Galah" is also derogatory Australian slang, synonymous with 'fool' or 'idiot'. Because of the bird's distinctive bright pink, it is also used for gaudy dress. A detailed, yet comedic description of the Australian slang term can be found in the standup comedy performance of Paul Hogan, titled ''Stand Up Hoges''. Another famous user of the slang "galah" is Alf Stewart from ''Home and Away'' who is often heard saying "Flaming galah!" when he is riled by somebody.
The Australian representative team of footballers which played a series of test matches of International Rules Football against Irish sides in the late 1960s was nicknamed "The Galahs" .
