About These Birds
Upland Goose
A large sheldgoose with strong sexual dimorphism: males are white with black back barring; females are warm brown with barred flanks. Common in Patagonian and Falkland Islands grasslands. Gregarious; forms large flocks outside breeding season. Grazes on short grass and agricultural land.
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.
