About These Birds
New Zealand Scaup
A small compact all-dark diving duck with a yellow eye in males, known in New Zealand as the 'black teal.' Endemic to New Zealand. The only native diving duck still widespread on both main islands. Gregarious; forms large flocks on deep mountain 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.
