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
A large distinctive shelduck with a white body, dark green head, broad chestnut breast band, and a bright red bill with a knob in males. Common along European and Asian coasts and estuaries. Nests in rabbit burrows or hollow trees. Large moult migrations concentrate in Germany's Wadden Sea.
