About These Birds
Long-tailed Duck
A medium-sized Arctic sea duck (~780 g) in family Anatidae, males having elongated central tail feathers. Breeds across circumpolar tundra; winters in large flocks on coastal and open-ocean waters. Dives to impressive depths for crustaceans, fish, and mollusks. Vulnerable; steep population declines linked to bycatch in fishing nets and climate change.
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.
