The Sulphur-crested Cockatoo is native to the eastern and northern parts of Australia, including Tasmania and New Guinea. It prefers forested areas, savannahs, mangrove swamps, and has adapted well to urban environments.
Lifespan in the wild is approximately 40-60 years, in captivity – 70-80 years with proper care. Males and females weigh between 800 to 1000 grams. Body length is 45-50 cm, wingspan is up to 1 m. Sulphur-crested Cockatoos are known for their social nature and loud vocalizations. They often live in flocks and form monogamous pairs. Nesting occurs in tree hollows. The female lays 2-3 eggs, and the incubation period lasts about 25 days. Both partners participate in feeding the chicks, which leave the nest at 10-12 weeks.
Sulphur-crested Cockatoos are omnivores. They feed on seeds, fruits, nuts, berries, flowers, and occasionally insects. In urban areas, they might consume human food leftovers. Fossil records show the long development of the cockatoo family in Australia and nearby islands.
Sulphur-crested Cockatoos are popular as pets due to their social nature and ability to mimic sounds. They have appeared in films and TV shows and are symbolic of Australia, playing a significant role in local culture.
According to the International Union for Conservation of Nature (IUCN), the Sulphur-crested Cockatoo is classified as “Least Concern” although its population may decrease in some areas due to deforestation and illegal poaching.
