Baudin's Black Cockatoo, also called the Long-billed Black Cocokatoo to distinguish from the shorter, wider bill of the similar
Carnaby's Black Cockatoo, is native to southwest Australia (as is Carnaby's). Like Carnaby's, it has a short crest and white in its tail feathers.
They used to be considered the same species but were separated, mainly on the basis of the different bills, in the 1990s.
Males (above), like the related Yellow-tailed Black Cockatoos, have a dark beak and pink eye-rings.
The white cheek mark is longer but fainter than the female's. The black feathers have a thin light edge.
The black plumage is slightly irridescent.
Females and juveniles have a light beak and grey eye-rings.
Females have less extensive but brighter white cheeks. Their black feathers are more strongly scalloped with white.
