One, two, three eyelids! Owls have an eyelid for every occasion. Like us, they have an upper and a lower lid, and blink by lowering their upper lid. In other situations, they raise their lower lid. The nictitating membrane is an additional semi-transluscent eyelid that moves from the inside corner of the eye toward the outside to protect the eye while hunting as well as clean and hydrate the eye. We've slowed down the video so you can get a better look at the bonus lid in action! #Owls #AnimalFa
