About These Birds
Andean Teal
A small brown teal with yellow bill and green speculum. Closely related to Yellow-billed Teal; sometimes considered conspecific. Restricted to high-altitude Andean wetlands of Colombia, Ecuador, and Peru. Listed as Near Threatened due to wetland loss.
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.
