3. Can owls blink?

Owls possess a dramatic fierce stare. It makes some of us wonder if they can blink. The answer is yes, owls can blink. An owl has not one, not two, but three eyelids: one for blinking, one for sleeping and another one called the nictitating membrane which is a thin layer of tissue that closes diagonally across the eye to keep the eye clean and healthy. Their large, face-forward eyes give owls their binocular vision. This means owls can see an object with both eyes at the same time, and in 3 dimensions similar like humans. The field of view for an owl is about 110 degrees, with about 70 degrees being binocular vision.
