Harlequin Ducks like to live on the edge. They spend their days in river rapids and crashing surf. Both males and females have a white patch in front of their eyes and round white spots behind their ears. Another common name for the Harlequin Duck is Sea Mouse, a reference to squeaking noises they make when in large groups.
