Carnaby’s Black Cockatoo (Calyptorhynchus latirostris)
The Carnaby’s Black-Cockatoo has white tail panels and white cheek patches. Male and females can be distinguished by the colouring around their eyes; males have a pink eye-ring and females have a grey eye-ring. Carnaby’s Black Cockatoos can live up to 40 to 50 years in the wild.
The population of Carnaby’s Black Cockatoo has dropped by 50% in the last 45 years, and a large portion of the existing birds are older than breeding age. Numbers have declined due to the destruction of their habitat and competition for nesting hollows. Carnaby’s Black Cockatoos are endemic to Southwest Western Australia, which means they do not occur anywhere else in the world. They are specially protected under both Commonwealth and State legislation.
During the nesting season Carnaby’s Black Cockatoos inhabit native woodland areas and nest in the hollows of mature Eucalyptus trees. After the breeding season Carnaby’s Black-Cockatoos migrate to coastal areas, in particular pine plantations and Banksia woodlands. However, due to habitat loss they now also breed in the coastal areas of Perth if they can find suitable tree hollows surrounded by enough food and water. Warwick Open Space already contains a confirmed night-time roost site for Carnaby’s Black Cockatoo during the non-breeding season.
They feed on the seeds of Banksia, Hakea, Eucalyptus, Grevillea and Marri (Corymbia calophylla). They have also adapted to feeding on exotic species such as pines and cape lilac.
