About These Birds
Mexican Duck
墨西哥鸭，也称墨西哥鸭，是一种中型鸭子，栖息于墨西哥中部高原及美国西南部的湿地和河流。其羽色与雌性绿头鸭相似，呈褐色斑驳状，嘴部呈橄榄黄色。雄雌外形相近，常在浅水湿地觅食。该物种被列为濒危物种，受栖息地丧失和与绿头鸭杂交的威胁。
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.
