Justification of Red List category
This cockatoo has suffered an extremely rapid population decline (>80% over three generations), owing to unsustainable trapping for the cagebird trade. This has been exacerbated by ongoing forest loss. It is assessed as Critically Endangered. Future rates of population reduction are suspected to be lower, as the bulk of the population is now restricted to protected areas. 

Population size: 1200-2000 mature individuals

Population trend: decreasing

Extent of occurrence (breeding/resident): 965,000 km2

Country endemic: no
