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.
Orinoco Goose
A pale-headed chestnut-and-white goose-like bird with a narrow dark mane on the neck. Found on tropical river islands and forest-edge wetlands of the Amazon and Orinoco basins. Perches prominently in trees. Monogamous with strong territorial behavior.
