About These Birds
Tundra Bean Goose
A large brown goose with dark head and neck, orange-patterned black bill, and orange legs. Separated from Taiga Bean Goose as a distinct species. Breeds on Arctic and subarctic tundra; winters in eastern Asia and occasionally western Europe. More common in Japan and eastern China.
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.
