About These Birds
Laysan Duck
A tiny brown dabbling duck with distinctive white around the eye and green speculum. The most range-restricted waterfowl in the world; endemic to Laysan Island in the Hawaiian archipelago. Critically Endangered; brought back from single digits in the early 20th century. Feeds on brine flies.
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.
