The family, widely diffused over the world, includes the common crow, the raven, the fish crow, the rook, the jay, and the magpie. The common crow of North America is remarkable for its gregarious and predatory habits. They pair in March. The nest is built of sticks and is usually located in a low tree, preferably an evergreen, about 20 feet from the ground. Since the forests have been decreasing in area, crows have become bolder and now nest in orchards and solitary trees in open fields. They feed chiefly on worms and the larvae of insects. They also eat grain and seeds, whence they have sometimes been regarded as injurious to the farmer; but they amply repay him for what they take by destroying the vermin in his fields.
