About These Birds
Black-headed Duck
A small diving duck (~530 g) of South America, family Anatidae, and the sole member of genus Heteronetta. Inhabits freshwater marshes and lakes in Argentina, Bolivia, Brazil, Chile, and Uruguay. Unique among waterfowl as an obligate brood parasite, laying eggs in nests of coots and other waterbirds. Feeds on seeds and aquatic invertebrates. Least Concern.
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.
