About These Birds
Goosander
The largest merganser (~1.5 kg) in family Anatidae, males with glossy green heads and salmon-flushed white bodies. Breeds along rivers and lakes in northern Europe, Asia, and North America; winters on larger rivers and reservoirs. A pursuit-diver specializing in fish, using a serrated bill for grip. Least Concern with stable Holarctic distribution.
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.
