About These Birds
Barnacle Goose
A medium-sized cleanly patterned goose with a white face, black crown, neck, and breast, grey barred back, and white belly. Breeds in the high Arctic; winters in northwestern Europe. Famous in medieval times as the subject of the legend that it hatched from barnacles.
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.
