About These Birds
Siberian Scoter
A medium-large sea duck (~1.3 kg) of family Anatidae, closely related to White-winged Scoter and endemic to eastern Siberia and northeastern Asia. Breeds near boreal lakes and winters in coastal seas of East Asia. Feeds by diving for benthic mollusks and crustaceans. Least Concern; recently split from White-winged Scoter as a distinct species.
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.
