The Sulphur-crested Cockatoo, Cacatua galerita, is one of the larger and more widespread of Australia’s cockatoos. These birds range throughout the various climates in Australia, from Far North Queensland beyond the Iron Range Mountains, as well as parts of the Snowy Mountains. They are also numerous in Adelaide and southern South Australia and can be spotted north of Perth.
The Sulphur-Crested Cockatoo weigh about 28.2 ounces. Their distinctive call can be loud and it is meant to travel through the forest environments in which they live. They are curious and intelligent birds. They have adapted very well to urban civilization in Australia. Sulphur crested cockatoos may no longer be imported into the United States as a result of the Wild Bird Conservation Act. However, they have been bred in captivity.
Sulphur-crested Cockatoos, along with many other parrots, are susceptible to a widespread viral disease known as Psittacine Beak and Feather Disease, which causes the birds to lose their feathers and grow grotesquely shaped beaks.
They can be destructive to cereal and fruit crops, as well as timber structures such as house planking and trees. These birds have been known to engage in geophagy, the process of eating clay to detoxify their food.
