Meet the duck that's always dressed for Halloween! The Harlequin Duck's name refers to their brightly patterned plumage, which resembles the theatrical costume of a clown or harlequin character. Even their scientific name, Histrionicus histrionicus, comes from the Latin word meaning 'actor' or 'performer'. Harlequin Ducks are most at home in whitewater rivers and rough, rocky coastlines of the northern U.S. and Canada. They are one of very few duck species worldwide capable of breeding and raising their young in rapid mountain streams. Harlequin Ducks are strong swimmers, and feed by diving for aquatic prey.
