About These Birds
Coscoroba Swan
The smallest swan and the only member of its genus, differing from true swans with a more goose-like head, red-pink bill and legs, and all-white plumage with black wingtips. Found in southern South America. Swims gracefully and grazes shoreline vegetation. Loud coscoroba call is distinctive.
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.
