The migration of the Arctic tern is by far the longest normal migration of any known animal. Its migration starts up at its breeding ground around the arctic circle (northern Canada, Alaska, northern Russia, coast of Greenland). Then it goes winding down all the way to Antarctica for the summer there. It can be found feeding and flying around the coast for most of their time there. When their summer there is finished they go up the coasts of many different country, barely ever landing. They finish their migration back up in their breeding grounds. They have just concluded their 19,000 kilometer (12,000 mile) migration from the north to the south of the globe. During the whole year they migrate up to 70,900 kilometers. In a lifetime, the normal length of how much they have migrated is around 2.4 million kilometers.
