Piercing Eyes


This colorful eyelid is known as a nictitating membrane.  It is found in most predatory birds.  It is a clear membrane that the Great Grey Owl can use to cover the eye protecting it from thrashing prey, unseen branches while flying through dense forest, or just to re-wet the eye balls.  This owl’s nictitating membrane looks so colorful due to the reflection from the sun.
