About These Birds
Lesser White-fronted Goose
小白额雁是灰雁属中体型最小的种类，繁殖于西伯利亚北极冻原，越冬于东南欧、伊朗及中国东部。与白额雁相似，但体型更小，额白斑更大，眼圈黄色醒目。由于越冬地农业变化和猎捕压力，数量已大幅减少，被列为易危物种。
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.
