Strigidae—Typical Owls

Most owls are assigned to this family despite the size differences, varying from the tiny Elf Owl to the Great Horned Owl. In a general way, prey size varies with size of the owl, but prey also may vary with hunting habits; an owl that hunts primarily over grassland has a different selection of prey items than one cruising forest or brushland.
