Cockatoos enjoy spending their days in the trees, digging up things, and foraging for fruits or whatever else they might find to eat. Palm Cockatoos are usually in pairs, but maybe found singlely or in groups of five to six. Sometimes the Palm Cockatoos gather and engage in social interactions such as preening, forming displays, and just calling out to one another. Palm Cockatoos sometimes feed on seeds and fallen fruits that they may find, but they would rather eat plants than fruits. They also eat insects, and insect larvae.
Berries are common fruit that the Palm Cockatoos consume.
When male Palm Cockatoos are ready for courtship, they will display their beautiful feathers by stretching them to their full height, and approach the female, while calling to them at the same time. The age of maturation in the Palm Cockatoo is about four years old. The Palm Cockatoos lay only one egg per year. The chick will not emerge from its nest until approximately 100-110 days. About two weeks after leaving its nest, the chick still is not able to fly and is forced to depend on its parents for another six weeks.
