The Sulphur-crested Cockatoo is a parrot that is found mainly in the northern and eastern areas of Australia, including Tasmania, and in New Guinea and the Aru Islands, and has been introduced to the Perth area of Western Australia as well as New Zealand and Indonesia.
Sulphur-crested Cockatoos in the wild in urban areas have become a nuisance, as they use their strong beak to destroy timber decking and panelling on houses. In rural areas, they are a pest for farmers of grain, fruit, and nut crops and in Western Australia are a declared pest., They also emit a loud screeching sound, which has been described as like someone being strangled. They have been observed in flocks of up to 100 birds.
