About These Birds
Black-bellied Whistling-duck
A boldly patterned whistling-duck with a bright red bill, chestnut-and-black body, broad white wing stripe, and a distinctive whistling call. Common in freshwater wetlands from the southern United States to central South America. Nests in tree cavities. Often perches in trees—unusual for waterfowl.
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.
