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.
Lake Duck
A stiff-tailed duck (~665 g) of southern South America, family Anatidae, with males displaying ruddy plumage and a bright blue bill. Inhabits freshwater lakes, ponds, and marshes from Brazil to Patagonia. Dives for aquatic plants, seeds, and invertebrates. Least Concern; notable for the proportionally longest penis of any vertebrate relative to body size.
