Citron-crested Cockatoo Studies

The Yellow-crested Cockatoo, (Cacatua sulphurea), has suffered a precipitous decline in its population due chiefly to unsustainable harvesting for the local and international wild bird trades. Large-scale logging and conversion of forest for agriculture has further hastened this decline. Remaining numbers are down to 2500-10,000 individuals.

The Citron-crested Cockatoo (C.s. citrinocristata), a subspecies of the Yellow-crest, has suffered greatly as well. The WPT has funded part of the work, on the island of Sumba, of Margaret Kinnaird and Tim O'Brien from the Wildlife Conservation Society to study the Citron-crest and determine how to best to save remaining populations.

The World Parrot Trust also helped to successfully petition CITES to move this species to Appendix I status in 2005.
