Owls are raptors that belong to the Strigiformes order. They are found on every continent except Antarctica and can be immediately recognized by their round, flat faces and large forward-facing eyes. Owls have incredible night vision and hearing and are nearly silent in flight, making them remarkable night-time hunters. Their eyes are fixed in their sockets so to look around they must turn their head, which they can do up to 270 degrees.
There are two accepted families of owls, "typical" or "true" owls in the family Strigidae and barns owls in the family Tytonidae.
In the United States common owls include Barn Owls, Great Horned Owls, Barred Owls, Boreal Owls, Burrowing Owls, Long-eared Owls, Northern Pygmy Owls, Short-eared Owls, Great Gray Owls, Snowy Owls, Northern Saw-whet Owls, Northern Hawk Owl and Flammulated Owls.
