About These Birds
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.
Common Shelduck
翘鼻麻鸭是欧亚大陆西部沿海地区最常见的大型鸭子，以其鲜红色的嘴部（雄鸟具肉瘤）、黑绿色头部、栗色胸带和白色体羽的对比色彩著称，外形华丽。繁殖于欧洲和中亚，越冬于地中海、北非和中国南部。常在兔子洞或沙丘中营巢，以软体动物（主要是泥螺）和甲壳类为食。
