Cockatoo Information


The Lesser Sulphur-crested Cockatoo, or Yellow-crested Cockatoo, Cacatua sulphurea, is endemic to Lombok, Sumbawa, Noesa Penida Island in Indonesia and East Timor in Southeast Asia. There is a feral population in Hong Kong. Thus large group has apparently developed from a number of caged birds that have been released over many years.

This cockatoo is critically endangered endangered in its natural habitat where numbers have declined dramatically due to illegal trapping for the cage-bird trade. The current feral population is estimated at less than 10,000. It is, therefore, listed on Appendix I of CITES.



The plumage of ths cockatoo is all white, except for its long, forward-curling yellow crest. It has a loud and very raucous voice.
