The Arctic tern has the longest migration of any animal: about 44,000 miles (about 70,800 km) per year. The Arctic tern, a bird that weighs just 4 ounces (113 g), is the animal that has the longest migration. Migration is the seasonal travel of animals, generally from one climate to another, in order to take advantage of needed resources. Arctic terns travel from the North Pole to the South Pole and back, for a distance of about 44,000 miles (70,800 km) annually. It is unknown why they choose to migrate such a long distance. The birds typically start their migration in Greenland, then fly south to Antarctica for about five months before heading back north.
