A medium-sized diving duck. Males have rich chestnut-brown body, white eye, and blue-grey bill; females are similar but duller. Australia's only widespread diving duck. Nomadic; follows inland flooding. Forms large rafts on deep lakes.
Mandarinente
Die Mandarinente gilt weithin als die schönste Ente der Welt. In der ostasiatischen Kultur symbolisiert sie Liebe und Treue, da sie feste Paarbindungen eingeht. Anders als die meisten Enten nistet die Mandarinente in Baumhöhlen bis zu 9 Meter über dem Boden, sodass die erst einen Tag alten Küken zu Boden springen müssen.
