About These Birds
Hooded Merganser
A small fish-eating duck (~640 g) of family Anatidae, males bearing a dramatic fan-shaped black and white crest. Breeds in wooded swamps, rivers, and lakes in North America, nesting in tree cavities; winters on sheltered coastal and inland waters. Uses keen underwater vision to hunt fish and crayfish.

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.
