Pygmy-Owls' False Eyes

This Northern Pygmy-Owl appears to have eyes in the back of its head. But why? One theory is that large false eyes may create the illusion that the owl is much bigger than its 6 and 3/4-inch size. A more current theory is that the false eyes help protect the pygmy-owl's true eyes. Small birds will mob this diurnal owl, even striking it, directing some attacks at its eyes. If the large false eyes can take the brunt of these attacks, little harm will come to the Pygmy-Owl's vulnerable true eyes.More info and transcript at BirdNote.org. Want more BirdNote?
