Carnaby’s Black Cockatoo are endemic to WA but are rapidly in decline. Estimates put total population to be below 60,000.
The Northern Swan Coastal Plain Important Bird Area (IBA) supports up to 15,000 Carnaby’s Black-Cockatoo in the non-breeding season and a small number of breeding pairs. The birds are attracted to this area because of the presence of feed species in remnant vegetation containing Banksia heath and woodland, scattered marri (Corymbia callophylla) and tuart (Eucalyptus gomphocephala) trees and Pinus spp.
