<P> Most birds can not move their eyes , although there are exceptions , such as the great cormorant . Birds with eyes on the sides of their heads have a wide visual field , useful for detecting predators , while those with eyes on the front of their heads , such as owls , have binocular vision and can estimate distances when hunting . The American woodcock probably has the largest visual field of any bird , 360 ° in the horizontal plane , and 180 ° in the vertical plane . </P>
