The Family Cacatuidae includes cockatoos, a group of medium- to large-sized parrots native to Australasia, including Australia, Indonesia, and the Philippines. Cockatoos are easily recognized by their prominent crests and strong, curved beaks, which they use for cracking nuts and seeds. They are highly intelligent, social birds, often forming large flocks and exhibiting complex vocalizations and problem-solving abilities. Most species feed on seeds, fruits, and occasionally insects, and many are known for their playful and affectionate behavior in captivity. Cacatuidae play important ecological roles as seed dispersers and are popular in aviculture, though several species are threatened due to habitat loss and the pet trade.
