About These Birds
Barnacle Goose
A medium-sized cleanly patterned goose with a white face, black crown, neck, and breast, grey barred back, and white belly. Breeds in the high Arctic; winters in northwestern Europe. Famous in medieval times as the subject of the legend that it hatched from barnacles.
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.
