About These Birds
Bar-headed Goose
Famous as one of the world's highest-flying birds, crossing the Himalayas at altitudes exceeding 7,000 m during migration. Medium-sized, pale grey with two distinctive black bars on the white head. Breeds on high-altitude lakes; winters in South Asian wetlands. Specialized haemoglobin enables high-altitude flight.
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.
