Owl Owl 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. They are found in all regions of the Earth except polar ice caps and some remote islands. Owls are divided into two families: the true (or typical) owl family, Strigidae,
Origin of birds flight, in which developing wing structures served as a sort of parachute. Second, they achieved active flight by flapping the wings. He used "Archaeopteryx" as an example of this second stage. Finally, birds gained the ability to soar. Current thought is that feathers did not evolve from scales, as feathers are made of different proteins. More seriously, Nopcsa's theory assumes that feathers evolved as part of the evolution of flight, and recent discoveries prove that assumption is false. Feathers are very common in coelurosaurian dinosaurs (including the early tyrannosauroid "Dilong"). Modern birds are classified as coelurosaurs by nearly all palaeontologists,
