Owl, a bird of prey with a flat face and rosette of feathers about the eyes, making them appear large and conspicuous. There are about 200 species. For the most part they are birds of night and pass the day in secluded and dark places. A few, like the snowy owl and the hawk-owl, are day-birds. The common owls feed for the most part on smaller birds and field-mice. Since the latter are destructive to crops and vegetation the owls should be protected, if for no other reason than for their war upon these rodents. Preying at night, in their soft plumage flitting about silently, they dispose of animals that have hid by day from the hawk. Owls feed upon field-mice, rats, squirrels, fish, insects and other animal food, eating tfleir prey entire ; later the indigestible parts, rolled into a hard pellet, are ejected from the mouth, and these pellets found in numbers about roost-ing-spots. Owls generally live in woods, and are seldom tamed. They fall ready prey to man, being easily trapped and shot, and their nests as a rule are openly exposed. They nest early, their young being fed on animal food instead of fruit. Their eggs are always pure white. The cry of the owl is well-known. It may be added that when angry or frightened the bird strikes its mandibles together like castanets. The barn owls form a distinct family. They have long faces, the feather discs on which are nearly triangular, and they are often called monkey-faced owls. The familiar barn-owl seldom molests birds, is the enemy of rats, and should be givan all protection. In color it is pale
