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.
Ruddy Shelduck
A large orange-brown shelduck with a pale buff head, black neck ring (male only), white wing patches, and bright green speculum. Widespread from Morocco and southeastern Europe east to China. Sacred to Buddhists in Tibet. Nests in burrows, rock crevices, and ruins.
