About These Birds
Whooper Swan
A large all-white swan with a long neck and a distinctive yellow-and-black bill pattern—a large yellow wedge extending to the nostrils. The national bird of Finland. Calls with a bugling whooping resonance. Breeds in Eurasian subarctic; winters in northwest Europe and East Asia.
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.
