About These Birds
Spotted Whistling-duck
A small dark brown whistling-duck with bold white spots on its flanks, orange-red bill and legs, and a pale face. Found in tropical wetlands of New Guinea, the Philippines, and Indonesia. Often found near freshwater streams and flooded grassland. Less gregarious than other whistling-ducks.
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.
