About These Birds
White-winged Duck
A large dark duck with a pale speckled head, brownish body, and broad white wing patch visible in flight. One of Asia's most endangered ducks. Found in undisturbed lowland forest near rivers in South and Southeast Asia. Nests in large tree hollows. Threatened by deforestation and hunting.
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.
