About These Birds
Emperor Goose
A stocky silvery-grey goose with a white head stained orange-yellow from iron-rich water, black-and-white scaly body, and orange-yellow legs. Breeds on Alaska's Yukon-Kuskokwim delta; winters along the Aleutian Islands coastline. Strongly tied to coastal habitats year-round.
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.
