About These Birds
Plumed Whistling-duck
A large whistling-duck with long buff flank plumes extending beyond the folded wings, brown body, pink bill, and upright posture. Endemic to Australia. Gregarious, forming large grazing flocks on grasslands near water. Feeds mainly on grasses and sedges rather than aquatic plants.
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.
