MNBound Eagle Eye 4-14-13

Eagles have 3 eyelids. Eagles blink up as their top eyelid is larger than the bottom one. The additional inner eyelid is known as a nictitating membrane. Every three or four seconds, the nictitating membrane slides across the eye from front to back, wiping dirt and dust from the cornea. Because the membrane is translucent, the eagle can see even while it is over the eye. Bald eagles have two foveae or centers of focus, that allow the birds to see both forward and to the side at the same time. (Bald eagle Journal North 2012) Many thanks to the camera operators, Mark, Anthony & Lance.
