About These Birds

A small grey-brown teal with fine pale edging on feathers, red eye, and green speculum. Widespread and common in Australia and New Zealand. Highly nomadic in Australia; follows inland flooding. Found in a wide variety of freshwater habitats from permanent lakes to temporary claypans.
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.
