Animales migratorios: En el agua (Migrating Animals of the Water)
En marcha: Migraciones animales (On the Move: Animal Migration)
Why and how do animals migrate? Find out in this Spanish series for young readers, which covers the journeys--sometimes lifelong, sometimes accomplished in a 24-hour period--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, to the tiny ruby-throated hummingbird catching winds to carry it across the Gulf of Mexico, 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.
