About These Birds
American Black Duck
A large dark brown dabbling duck closely resembling a very dark female Mallard, with purple speculum, yellowish-olive bill in males, and orange legs. Common in eastern North America. Hybridizes freely with Mallard; pure populations declining in the interior.
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.
