About These Birds
Reunion Shelduck
An extinct shelduck formerly endemic to Réunion Island in the Indian Ocean. Known only from subfossil bones and brief historical records from the 17th century. Went extinct shortly after European colonization. No illustrations or detailed physical description of the living bird is known.
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.
