The Cockatoos are very lively and affectionate birds. They are quite cuddly and bond very closely with their owners. However, their sociability and need for affection means they demand a great deal of time from their owners. Deprived of affection, cockatoos will become depressed or exhibit neurotic behaviors. They are intelligent, playful, mischievous, and they can be exceptionally loud. They are somewhat excitable so sometimes don't do that well around young kids.

Cockatoos are prone to neurotic behavior including feather plucking and self-mutilation, especially if denied the affection and attention they need so strongly. Usually active, energetic and healthy, Cockatoo can suffer from common diseases like any other Parrots.
