Male cockatoo will open his wings, ruffles his feathers, and raising his crest while dancing and bouncing repeatedly in front of a female cockatoo for her to be attracted. When the female accepts the male, they will preen each other. After breeding, they will leave their group and find a nesting site. They make their nest in a tree hallows with a measurement of 16 to 100 ft. Female corella lay eggs for about 3 to 4 white eggs.

The incubation of eggs usually lasts for 30 days. Both sexes are good at parenting, in which they take turns in keeping their eggs moist by sitting on them during the incubation period. In addition, when they are already hatched, they feed their young chicks alternately. Young chicks mature between 4 to 5 and 6 to 7 years. The sexes of these young chicks are difficult to determine; DNA testing will be helpful to know their sexes.

Size and Weight

Common Disease/Illnesses

Psittacine Beak and Feather Disease (PBFD)

This disease is most common among other birds, including parrots, cockatoos like corellas, and other birds that belong to the Psittacidae family. This kind of disease is said to be a fatal viral disease because it results in death due to the infection that reduces the immunity caused by this disease. This disease is caused by the circovirus that kills the cells and infects the beak and the feathers of the birds.

The symptoms of this disease are the abnormal growth of their feathers and their beaks, loss of appetite, regurgitation, and diarrhea. This disease can also be transmitted from birds to birds and to humans who have direct contact with those infected birds. Furthermore, this disease has no cure, and vaccines are only now being developed.


This disease is caused by a virus that can get through direct contact with other infected birds, infected feces, nest boxes, dandruff, incubators, and feather dust. This disease can be a deadly virus to birds, but other cockatoos cannot die with this disease; instead, they will become the carrier of this virus for their whole life and spread this virus to other birds.

Young birds in cockatoos and other parrots are mostly the ones that are being targeted by this kind of disease, and many of the young birds can either die or become the carrier of this virus. Parrots that are already an adult will not be the carrier for the rest of their life; instead, they will only carry the virus for about 24 weeks and get cured completely. When an adult bird dies due to polyomavirus will only be determined by the veterinarian.


It is an infectious disease in humans that are being transferred to a sick bird or any susceptible species like guinea pigs, dogs, sheep, horses, and all bird species. This disease is caused by Chlamydia psittaci, a type of bacteria that often infects birds. The bird that is being infected by these bacteria will take some time before the symptoms will arise.

The common symptoms of Psittacosis are greenish feces, coughing, fluid running from their nose, and difficulty in breathing or loud breathing. The birds that have kind of symptoms will often die within 2 weeks, but some birds that are infected and do not show any of these symptoms may be a carrier of this bacteria which can eventually transmit to other birds.


It is a parasite that causes infection to many species of birds. This is due to a contaminated environment in which parasites mostly occurs. This parasite is usually found in drinking and recreational water and lives in the intestinal tract of infected species such as birds and other animals and also to humans.

The symptoms of this infection to birds include itching, diarrhea, loss of feathers, loss of appetite, and other malnutrition symptoms. In humans, it can cause intestinal symptoms like stomach cramps, flatulence, diarrhea, and nausea. These symptoms will result in dehydration and weight loss. However, some people or animals have no symptoms at all, but after a long period of time, these symptoms will eventually occur.
