Ecologists at the University of Hong Kong have conducted groundbreaking research on the Sulphur-crested Cockatoo and the critically endangered Yellow-crested Cockatoo, with major implications for their conservation. The research confirms the Triton Cockatoo as a distinct species and highlights the risks of hybridization and competition when introducing the wrong species during reintroduction programs. The study also identifies genetic differences among subspecies of the Yellow-crested Cockatoo, simplifying previous classifications. The findings emphasize the importance of incorporating genetic data into conservation planning.
