Bird's Eye; Bird's Ear

I kept looking at this Roseate Spoonbill thinking "something's odd about its coloration".

 

Most people don't think about a bird's ear, but if they sing they must have ears to hear a song. Birds have no earlobe, and usually the ear is covered up with feathers. This picture clearly shows a hole in the black band behind its eye. That's the bird's ear!
