Migration is one of the most fascinating and dramatic of all animal behaviors. From insects and birds to reindeer and giant whales, many animals fly, swim, walk, and even hitchhike in search of better food, milder climate, or suitable mate. Some cross entire oceans; a few even circle the globe. These marathon journeys animals take are filled with great tests of physical strength and endurance - as well as danger and sometimes death. In ""Animal Migration"", learn why animals are compelled to migrate and the various patterns and cycles of their migrations.
