About These Birds
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.
Blue-billed Duck

Inhabits deep freshwater lakes and swamps in southeastern and southwestern Australia. Dives for aquatic invertebrates and plant matter. Least Concern; dependent on permanent water bodies, vulnerable to drought cycles.
