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.
Mandarin Duck
The mandarin duck is widely considered the most beautiful duck in the world. In East Asian culture, mandarin ducks symbolize love and fidelity because they form strong pair bonds. Unlike most ducks, mandarins nest in tree holes up to 9 meters above the ground, and day-old ducklings must leap to the ground.
