Lakes, slow rivers, estuaries, and coastal lagoons. Often associated with parks and ornamental waters in Europe.

Despite its name, not truly mute: gives hissing snorts and low grunting when threatened. Wings produce a loud rhythmic whistling throbbing sound in flight.

About These Birds
Harlequin Duck
A compact sea duck (~550 g) in family Anatidae, males strikingly patterned in slate-blue with chestnut and white markings. Breeds along fast-flowing mountain streams in North America, Greenland, and Iceland; winters on rocky surf-swept coastlines. Feeds on aquatic invertebrates. Least Concern with stable populations across its range.
Höckerschwan
Der Höckerschwan gehört zu den schwersten flugfähigen Vögeln; Männchen können bis zu 14 kg wiegen. Trotz seines englischen Namens („Mute Swan“, stummer Schwan) ist er keineswegs stumm und gibt zischende, grunzende und schnaubende Laute von sich. Höckerschwäne gehen lebenslange Paarbindungen ein, und ihre aggressive Verteidigung des Brutreviers ist bekannt.
