About These Birds
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.
New Zealand Merganser
An extinct flightless or near-flightless merganser (~900 g) of family Anatidae, endemic to the subantarctic Auckland Islands of New Zealand. Inhabited forested riverine habitats and fed on freshwater fish and invertebrates. Exterminated by hunting and predation from introduced mammals; last reliably recorded in 1902 and declared Extinct.
