About These Birds
Common Scoter
A medium-sized sea duck (~1.1 kg) in family Anatidae, males entirely black with a knobbed yellow bill. Breeds on moorland lakes in northern Europe and western Siberia; winters in large flocks on shallow coastal seas. Dives for bivalves and crustaceans. Least Concern; monitored due to sensitivity to offshore energy development and oil spills.
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.
