About These Birds
Eastern Spot-billed Duck
A large brown dabbling duck with a yellow-tipped black bill, without the red spot of its Indian relative, and a green speculum. Found across northeastern Asia. Partially migratory; breeds in northern China, Korea, and Siberia; winters farther south and east.
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.
