The Arctic Tern does just that. A recent mapping project has shown that, starting in Greenland, they travel down either the American or African coastlines to Antarctica, then fly back in an S-shape up the center of the Atlantic. The journey is 43,000 miles round-trip, and every spring the 3.5-oz. bird ends up back in the Arctic. Scientists were especially interest in the serpentine path terns take across the Atlantic, because it shows that they “know” instinctively to fly counter-clockwise in the southern hemisphere, and clockwise in the north!
