About These Birds
Barnacle Goose
白颊黑雁是北极雁类，繁殖于格陵兰、斯匹次卑尔根和俄罗斯新地岛，越冬于英国、爱尔兰及西欧北海沿岸。头颈黑色，脸白色，体羽灰黑色带细横纹，腹部白色。以草地和农田植物为食。在中世纪，人们误以为其从藤壶中孵化而来，故又称藤壶雁。
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.
