The animal known for migrating thousands of miles is the Arctic Tern. This remarkable bird is known for having the longest migration of any animal, traveling about 71,000 kilometers (about 44,000 miles) annually. It breeds in the Arctic and then migrates to the Antarctic for the winter, experiencing two summers each year. This extensive journey allows Arctic Terns to exploit seasonal food sources effectively. The Tern's ability to navigate across vast distances using innate instincts, alongside environmental cues, is fascinating. Their migration not only showcases their endurance but also highlights the challenges faced by migratory species amid environmental changes.
