About These Birds
Common Goldeneye
A medium-sized diving duck (~920 g) of family Anatidae, males with iridescent green heads and a round white cheek spot. Breeds near boreal lakes and rivers, nesting in tree cavities across Eurasia and North America; winters on coastal and inland waters. Dives for invertebrates, fish, and plant matter. Least Concern with widespread distribution.
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.
