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.
Orinoco Goose
A pale-headed chestnut-and-white goose-like bird with a narrow dark mane on the neck. Found on tropical river islands and forest-edge wetlands of the Amazon and Orinoco basins. Perches prominently in trees. Monogamous with strong territorial behavior.
