About These Birds
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.
Crested Shelduck
A mysterious possibly extinct shelduck known from only a handful of specimens collected in Korea and Siberia before 1916. Males had a black head with green sheen, white crest, and colorful body. No confirmed sightings since 1971. Possibly on the edge of extinction or already extinct.
