I had the wonderful pleasure of visiting the San Diego Zoo this weekend. And as I was looking around...this owl happened to be looking at me! I learned that an owls eyes are so big that they have a small brain which results in them being one of our less intelligent feathered friends.
Another fact below is taken from http://www.sandiegozoo.org/animalbytes/t-owl.html
Vision— Animals that are active at night usually have large eyes, which lets them make use of any available light. With owls, the eyes are so big that they can’t move in any direction. This means that an owl must move its entire head to follow the movement of prey, but it also gives it better focus with both eyes looking in the same direction. And even though it seems that an owl can twist its head completely around, most owls actually turn their heads no more than 270 degrees in either direction.
