This species is listed as Vulnerable because remote-sensing techniques indicate that the lowland forest on which this species depends for nesting is being cleared at such a rate that the population is likely to be undergoing a rapid decline.

50cm. White cockatoo, bases of head feathers undersurfaces of wing and tail suffused with yellow. Yellow crest feathers only visible easily when crest is erect. Grey-black bill and feet and diagnostic sky-blue wattled skin around the eyes (much darker than on other similar cockatoos).
Buchanan et al. (2008) calculated the rate of forest loss within the species's range on New Britain as 35% over three generations.
It inhabits tropical lowland rainforest up to an altitude of 1000 m. Although it occurs in disturbed forest including degraded forest and gardens, it presumably relies on intact forest with large trees for nesting (Dutson 2011).
Rapid conversion of lowland forest to oil plantations over the last thirty years is likely to have caused a significant loss of breeding habitat. Although it is rare in the international trade, even limited trapping would be a cause for concern.
Conservation actions underway
Conservation actions proposed
Monitor populations and breeding success in logged and unlogged forest throughout its range. Ensure the protection of a number of large areas of lowland forest on New Britain as part of a protected area network for the island. Monitor trends in the national and international trade of this species. Conduct awareness campaigns to discourage trapping of the species. Discourage the logging of trees with holes or other suitable nesting cavities.
