The Arctic Tern (Sterna paradisaea) may be a small bird, but it undertakes the world's longest migration each year when it travels almost from pole to pole. After breeding in the Arctic Circle, these birds migrate during the Northern Hemisphere winter to the border of the Antarctic ice pack. The roundtrip migration is almost equal to flying all the way around the earth -- totaling approximately 21,750 miles (35,000 kilometers).
