This title is suitable for children of ages 7 to 9 years. Autumn is the time that many birds fly to places with warmer climates. Spring signals their return trip. Many birds migrate to keep warm and to find food that is not available in their winter homes. Not all migration is seasonal, however. Animals that graze, such as wildebeests, zebras, and antelopes, migrate in huge herds of millions of animals to find water and new plants to eat. There are also animals, such as humpback whales, sea turtles, and salmon, which migrate to reproduce. This book, containing fabulous photographs, will bring migrating animals, the navigational tools they use, and the challenges they face, to life for children.
