Subspecies There are four recognised subspecies: A 2024 genetic study found that the Triton cockatoo is genetically distinct from the two Australian forms of sulphur-crested cockatoo and should therefore be considered a separate species, ''Cacatua triton''. Description Sulphur-crested cockatoos are long, with the Australian subspecies larger than subspecies from New Guinea and nearby islands. The plumage is overall white, while the underwing and -tail are tinged yellow. The expressive Crest (feathers), crest is yellow. The bill is black, the legs are grey, and the eye-ring is whitish.
