Sulphur-crested cockatoo

Distribution

There were four recognized subspecies of sulphur-crested cockatoos: Triton cockatoos, Eleanora cockatoos, Mathews' cockatoos, and greater sulphur-crested cockatoos. Triton cockatoos are native to New Guinea. Eleanora cockatoos originate from the Aru Islands. Mathews' cockatoos originate from the Gulf of Carpentaria in Australia. And greater sulphur-crested cockatoos live in eastern Australia, from Cape York to Tasmania.

Introduced species

Within Australia, sulphur-crested cockatoos of the nominate race have also been introduced to Perth, which is far outside the natural range. Outside Australia, they have been introduced to Singapore, where their numbers have been estimated to be between 500 and 2000.
