For most of the year, The Greater Sulfur Crested Cockatoo lives in flocks of up to hundreds of birds. Early in the morning the birds fly to a watering place to drink.

If an intruder approaches, the lookouts screech loudly and the whole flock flies away. At sundown, the birds return to the trees, where they perch overnight. During mating season, the flock split up in small groups and pairs. To attract a female, the male struts towards the female with his crest fanned out. He moves his head in a figure-eight pattern and make soft, chattering noises. The pair bond by preening each other and touching each otherís bills.
