Join animals on epic adventures, and travel through the natural world with them. Across the world, billions of animals are embarking on incredible journeys. Many are in search of food, some are looking for a mate, lots are heading to a warmer climate, and others are just seeking a new home. Follow the mass migrations of entire species with amazing facts and maps that tell the stories of nature\'s most amazing journeys. Discover the record-breaking flight of the Arctic Tern, who travels from the Arctic to the Antarctic and back every year, the sharks that follow plankton for enormous distances from the ocean depths to the surface from night to day, spiderlings that shoot strands of thread into the air and ride them like a balloon in the wind to new islands, the mites that hitchhike on beaks of hummingbirds to be carried to new locations, the millions of wildebeest following the rain across the Serengeti, or the Monarch butterflies who use Earth\'s magnetic field to trace a path along the west coast of North America.
