About These Birds
Hawaiian Goose
Hawaii's state bird and the world's rarest goose, recovered from near extinction. A medium-sized brownish goose with a black face, pale buff neck with diagonal stripes, and reduced webbing between the toes adapted for walking on lava. Grazes on volcanic slopes and coastal areas.
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.
