Exactly where are an owl's ears? Well, the eyes of this Great Gray Owl are set in a broad, dish-shaped face.

Ridges of tiny hair-like feathers rim the owl's face, creating "facial disks." Just below the margins of the facial disks, concealed by feathers, are the openings to the owl's ears. 

The facial disk acts as a sound collector - like an old-fashioned ear trumpet - and guides sound to asymmetrically placed ears. There's always more to learn about owls' ears!
