Harlequin Duck – Length: 17 inches, Wing span: 26 inches
The Harlequin Duck has an unusual pattern of habitat use and migration. It breeds along cold, fast-flowing mountain streams, but flies to the coast to spend the winter. Harlequin Ducks are excellent swimmers, able to cope with both fast currents and powerful surf, each of which they encounter at different times of the year.
Harlequin Ducks typically either don’t breed or they have poor success at breeding until they are five years old. They have been known to live over 10 years in the wild. Iceland is the farthest east that Harlequin Ducks breed, and is the only breeding location in Europe.
