They are white overall except for the underside of their wings and their tail, which has a tinge of yellow. They have a black or dark-gray beak, gray legs, and the ring of their eyes is whitish. The eye color of males is typically black, while that of females is red or brown. They are 44 to 55 cm (17 to 22 inches) in length.
These birds have a very loud call. Their shriek is meant to travel to long distances through the forest. These birds are very often confused with the Corella that can be found in Australia. However, Corellas are smaller in size, do not have the yellow crest on their heads, and their beaks are of paler colors.
One good idea is to get a big stock of toys and then rotate them every couple of weeks so that the bird always has something new and exciting in the cage to keep him/her busy and happy. Keep in mind that if these birds get too bored, they start pulling out their feathers.
These birds can be found throughout Tasmania and northern and eastern Australia. In recent years, they have been introduced to New Zealand and Indonesia. These are birds that stay in the same place all year round, and usually they can be found in wooded areas that are close to human settlements.
The diet of cockatoos consists of seeds, nuts, and roots in the wild. They like to eat in groups. If a flock of them is eating on the ground, then one of them sits on a high tree and keeps a lookout for predators and other potential dangers. They bite off branches and twigs when not eating, to play with and keep their bills trimmed down when in the wild.
Cockatoos are considered easy to breed in captivity. The only thing is to move the male to a different cage in case of multiple birds, because he can turn mean. It is also recommended that a large aviary is used to help prevent any accidents. Instead of breeding them, adopting one that needs a home is a better option.
