The Harlequin Duck is a very beautiful species of sea duck found along coastal waters across North America and eastern Asia. They prefer fast-moving water and breed near fast-flowing streams.
Male Harlequin Ducks have a striking plumage of slate blue, white, and chestnut. They get their name from the colorful masked character Harlequin from an Italian style of improvisational comedy theater.
Harlequin Ducks feed by diving for marine invertebrates, fish, and aquatic insects. They may also feed by dabbling.
