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.
Velvet Scoter
A large sea duck (~1.6 kg) of the family Anatidae, males black with a white wing patch and yellow-sided bill. Breeds on lakes and rivers of northern Eurasia; winters on coastal waters of Europe. Forages by diving for mollusks and crustaceans. Vulnerable due to significant population declines attributed to hunting pressure and habitat degradation.
