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.
Torrent Duck
A slim agile duck perfectly adapted to fast-flowing Andean rivers. Males are striking with a white-and-black-streaked head, red bill, and chestnut breast; females are rufous below. Forages by diving and swimming in violent rapids, holding on to boulders with strong claws. Monogamous with strong site fidelity.
