Arctic terns raise their young during the Arctic summer. Then they fly south to the Antarctic, where summer is just beginning. In the fall they fly north again, making a round trip of 22,400 miles (36,000 km)! The Arctic tern sees more daylight each year than any other creature.   Previous: Back Book: 1001 Section: Human World Chapter: Polar Regions
