About These Birds
Pacific Black Duck
A large brown dabbling duck with a distinctive bold head pattern: dark crown, buff cheeks with two dark stripes, and a green speculum. The Mallard equivalent in Australasia. Widespread and common in Australia, New Zealand, New Guinea, and Pacific islands. Very tolerant of human presence.
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.
