But according to a genetic study, they are actually 2 separate species. Learn more Opening https://cosmosmagazine.com/nature/birds/sulphur-crested-cockatoo-triton/

The study finds that a type of cockatoo which inhabits much of New Guinea – the Triton cockatoo – is a distinct species from sulphur-crested cockatoos.

This means that re-introducing Australian birds to places in New Guinea, where Triton cockatoos are struggling, could do more harm than good.

“Introducing the wrong species in the wrong place could jeopardise their long-term survival in the wild through hybridisation or competition between the Triton cockatoo and the sulphur-crested cockatoo, potentially even disrupting ecosystems in the long term,”

sulphur-crested cockatoo is 2 species

The study finds that a type of cockatoo which inhabits much of New Guinea – the Triton cockatoo – is a distinct species from sulphur-crested cockatoos.

“Introducing the wrong species in the wrong place could jeopardise their long-term survival in the wild through hybridisation or competition between the Triton cockatoo and the sulphur-crested cockatoo, potentially even disrupting ecosystems in the long term,”
