About These Birds
Yellow-billed Duck
A large dark brown dabbling duck with a striking bright yellow bill. Common in freshwater wetlands across eastern and southern Africa. Often found in groups near reed beds. Closely related to the Mallard lineage. Common in parks and on large 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.
