Slender-billed Cockatoos are roughly the same size as the Ducorps Cockatoo, and somewhat similar in appearance. They are funny-looking birds with crests that are too small and beaks that are too big! Even their coloring is a little funny. They are entirely white or pinkish, except for patches of orange or salmon over their eyes (which looks like a mask) and throat (which looks like a bib). They have the bare, blue patch of skin around their eyes that is typical of Cockatoos.
