About These Birds
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.
Common Eider
The heaviest duck in the Northern Hemisphere (~2 kg), family Anatidae. Breeds colonially on rocky coasts and islands of the North Atlantic and Arctic. Dives for mussels and crustaceans in shallow marine waters. Females line nests with insulating down. Near Threatened due to recent declines in parts of its range from hunting and pollution.
