They hunt at night and roost during the day. Their eyes are bigger than most birds and take up more room in their head than their brain does. The owl has to turn its head to look from side to the side because it cannot roll its eyes. Owls can focus on objects both near and far at the same time. A great gray owl can see a mouse two football fields away.
Owls also have a third eyelid which keeps the eye moist and helps protect the eye.
It has fourteen bones in its neck. It can turn its head farther around than we can. It can look behinditself. Sometimes it seems to have its head on backward. It can also turn its face upside down.
