About These Birds
Trumpeter Swan
North America's largest native waterfowl and one of the heaviest flying birds, with all-white plumage, a long neck, and all-black bill. Named for its resonant bugling call. Recovered from near extinction in the 20th century through active conservation. Breeds in northern wetlands.
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.
