長喙黑鳳頭鸚鵡

Baudin's Black-Cockatoo is a large, critically endangered black cockatoo endemic to the forests of southwestern Australia. It is distinguished by its white cheek patches, white-tipped tail feathers, and long bill adapted for extracting seeds and marri nuts. Severe habitat loss, slow reproduction, and competition for nest hollows have driven its population to critically low levels.
