About These Birds
Andaman Teal
A small dark brown teal with a white throat and chin patch, green speculum, and dark bill. Endemic to the Andaman and Nicobar Islands in the Bay of Bengal. Vulnerable; threatened by habitat loss and hunting. One of the least-known ducks in Asia.
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.
