About These Birds
Cape Barren Goose
A large pale grey goose with a distinctive lime-green cere at the base of its short dark bill and pink legs. Endemic to southern Australia. Grazes on grasses and low scrub on offshore islands. Territorial and aggressive; pairs hold year-round territories. Can survive without fresh water.
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.
