Why and how do animals migrate? Find out in this series for young readers, which covers the journeys of an amazing range of animals. From the Arctic tern that makes a yearly round-trip from the Arctic to the Antarctic to the African elephant circling the drying plains of Africa, moving from water hole to water hole, animal migration is astounding. These books help students understand how food supply, climate, and human activity interact to form a hospitable or inhospitable environment for animals. Students will learn that migration is an often predictable, often critical form of animal behavior and that it is an adaptation that helps individual animals, groups, or even entire species survive.
