In its non-breeding plumage, the white-faced ibis is very similar to the glossy ibis except that it tends to be slightly smaller and its plumage has a somewhat warmer color. Breeding adults have a pink, bare face bordered with white feathers (rather than a bluish bare face with no bordering feathers), a grey bill, and brighter-colored, redder legs. Adults have red eyes year-round, whereas glossy ibises have dark eyes. Juveniles of the two species are nearly identical.

I wonder why they are called white faced?
