Galahs form permanent pair bonds, although a bird will take a new partner if the other one dies. The nest is a tree hollow or similar location, lined with leaves. Both sexes incubate the eggs and care for the young. There is high chick mortality in Galahs, with up to 50 % of chicks dying in the first six months. Galahs have been recorded breeding with other members of the cockatoo family, both in the wild and captivity.
