About These Birds
Tundra Swan
A medium-sized white swan with a black bill often marked with a small yellow spot at the base. Migrates in large flocks between Arctic tundra breeding grounds and temperate wintering areas. Two subspecies: Bewick's Swan in the Old World and Whistling Swan in the New World.
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.
