About These Birds
Southern Pintail
A small island duck found on the remote Kerguelen and Crozet archipelagos in the sub-Antarctic Indian Ocean. Closely related to Northern Pintail. Non-migratory island endemic; small population threatened by introduced predators and overgrazing by rabbits.
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.
