About These Birds
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.
Black Scoter
A medium-sized sea duck (~1 kg) in family Anatidae, males entirely black with a bold orange-yellow knob at the bill base. Breeds on boreal and tundra lakes of North America and eastern Russia; winters coastally. Dives for mollusks and crustaceans. Near Threatened following population declines linked to habitat loss on breeding grounds.
