About These Birds
Yellow-billed Teal
A small brown teal with a distinctive bright yellow bill, dark crown, green speculum with white borders, and orange legs. Widespread in South American highland and lowland wetlands. One of the most common ducks in the Andes. Gregarious; forms large flocks outside breeding season.
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.
