About These Birds
Common Goldeneye
A medium-sized diving duck (~920 g) of family Anatidae, males with iridescent green heads and a round white cheek spot. Breeds near boreal lakes and rivers, nesting in tree cavities across Eurasia and North America; winters on coastal and inland waters. Dives for invertebrates, fish, and plant matter. Least Concern with widespread 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.
