About These Birds
Hawaiian Duck
A medium-sized duck resembling a female Mallard, with mottled brown plumage and green speculum. Endemic to Hawaii; hybridizes with feral Mallards, threatening its genetic integrity. Found on freshwater wetlands of Kauai and other islands. Endangered; conservation focus on reducing hybridization.
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.
