About These Birds
Yellow-billed Pintail
A slender long-tailed duck with pale buff-brown body, dark brown cap, yellow-sided bill, and a distinctive long pointed tail. Found from the South American subtropics to the Falkland Islands and South Georgia. Gregarious; forms large post-breeding flocks.
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.
