About These Birds
Snow Goose
A distinctive goose with two morphs—white with black wingtips, or 'blue morph' with dark body and white head. Large flocks create spectacular migration events. Breeds in the Arctic; winters in the United States and Mexico. Population growth has caused severe overgrazing of Arctic salt marshes.
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.
