Owls are birds from the order Strigiformes, which includes about 200 species of mostly solitary and nocturnal birds of prey typified by an upright stance, a large, broad head, binocular vision, binaural hearing, sharp talons, and feathers adapted for silent flight.
Exceptions include the diurnal northern hawk-owl and the gregarious burrowing owl.
Owls hunt mostly small mammals, insects, and other birds, although a few species specialize in hunting fish.
