The Common Murre is among the few species of birds that can "fly" under water. When above the water, the 18"-long murre must flap frantically to stay aloft.

Common Murres, black and white torpedoes with feathers, chase down fish even several hundred feet below the surface. Cornell's Macaulay Library offers audio and video of Common Murres.
