About These Birds
Long-tailed Duck
A medium-sized Arctic sea duck (~780 g) in family Anatidae, males having elongated central tail feathers. Breeds across circumpolar tundra; winters in large flocks on coastal and open-ocean waters. Dives to impressive depths for crustaceans, fish, and mollusks. Vulnerable; steep population declines linked to bycatch in fishing nets and climate change.
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.
