This vibrant volume shows numerous animal groups that migrate for various lengths of time and for various reasons. Most readers know that a V-shaped flock of geese flying overhead on a fall or winter's day is migrating to a better climate. Colorful photographs allow readers to follow birds, zebras, whales, turtles, and more as they migrate to find food, shelter, breeding grounds, or more suitable climates. Readers will learn how air, land, and water migration differ, what landmarks and senses animals rely on to get them from place to place, and why migration is essential for survival
