Long-billed Corella Cacatua tenuirostris/Cacatua pastinator

The Long-billed Corella or Cockatoo, also called the Slender-billed, is a name for two separate species: one native to Eastern Australia (Cacatua tenuirostris) above and immediately below, and one native to Western Australia (Cacatua pastinator) third row.

Both the Eastern and the Western Long-billed have bare eye rings and pink facial markings. The Eastern Long-billed (above) also has a "cut-throat" red marking on the neck and red above the eye.

The Western Long-billed (above) doesn't have the cut-throat marking or red over the eye. Like all cockatoos, both have a raisable crest. The long upper beak of both is used to dig up seeds, bulbs and roots, and since these gregarious birds eat in large flocks, they can be agricultural pests.
