Animal migration : remarkable journeys in the wild

Summary: This guide explores the mysteries of animal migration over land, through oceans, and by air. With more than 300 color photographs, maps, and illustrations, it covers every continent as it traces the routes of some 50 remarkable migrations -- including those of polar bears, wildebeest, hummingbirds, iguanas, and sharks. The author describes the navigation, reproduction, and feeding strategies of these animals and discusses migrations that stand out for their extraordinary challenges, such as those that take animals unthinkable distances across hostile territory. This book also includes a catalog of migration hot spots around the world -- places where the planet's greatest animal voyages can be observed.
