Puffins are built for swimming underwater rather than for flying, and at the Alaska SeaLife Center in Seward, a mutli-level seabird display allows visitors to watch puffins and other sea birds dive to the bottom of the enclosure for food. When they dive, puffins flap their wings through the water, appearing to fly.
