All representatives of the animal world — birds, fish, crustaceans, reptiles, mammals, insects and even slime molds make great journeys by water, land or air. Migration is one of the greatest mysteries of the natural world. Without a compass or GPS devices, birds fly thousands of kilometers from Europe to Africa, where insects and berries abound, salmon cross oceans to return to the rivers in which they were born, and monarch butterflies spend their entire adult lives traveling from the meadows of the United States and Canada to the forests of Mexico. During its 30-year life, the polar tern flies a distance equal to five flights to the moon and back. This book examines in detail how and why different animals migrate. The simple text is filled with fascinating facts, and colorful illustrations show the wonders of our extraordinary planet and the species that inhabit it. Leatherback sea turtles are one of the most seasoned ocean explorers. Together with the sea currents, they swim in search of delicious jellyfish and travel up to 17,000 km per year, and then return to lay their eggs on the very beach where they were born. Soaring birds are limited by the height of thermal currents, while waving birds can fly at high altitudes. That's why we rarely see many small migratory birds; they usually fly so high that they can't be seen from the ground.
