About These Birds
Eastern Spot-billed Duck
A large brown dabbling duck with a yellow-tipped black bill, without the red spot of its Indian relative, and a green speculum. Found across northeastern Asia. Partially migratory; breeds in northern China, Korea, and Siberia; winters farther south and east.
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.
