About These Birds
Redhead
A medium-sized diving duck. Males have a rounded rufous-red head, black breast and rear, and grey body; females are brown. Highly parasitic breeder—females frequently lay eggs in other ducks' nests. Found across North America. Winters on large bays and coastal waters.
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.
