É a subespécie denominada tundra do complexo do ganso-de-bico-laranja. As suas populações são monitorizadas como entidade separada em algumas jurisdições.
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.
