Galahs are a smaller and more colourful version of the sulphur-crested cockatoos.
Where I live I tend to see them only in pairs.Large flocks are seen more in the open and inland areas.Like their sulphur-crested cousins, they are frequently seen in the suburbs of Melbourne nowdays. When I was a boy, I don't remember seeing them at all in the suburbs.
Some parrot species are definitely on the way out, but not these cockatoos,who have expanded their habitats markedly in the last fifty years.

Galahs, like all cockatoos are cheeky and noisy by nature.
Their powers of mimicry are remarkable. When I was a boy,neighbours had a pet galah who talked with his owners and copied his owners wheezing cough so expertly you never knew whether it was human or bird who was coughing.

Though galahs can be seen in flocks of hundreds,they always pair off and usually keep their mate for life.

A common sight in country Australia.

Most Australians have a soft spot for these likeable birds,except perhaps wheat-growing farmers.Cockatoos often devastate grain crops.
