Historically restricted to the Mascarene Islands (Mauritius and Réunion) in the Indian Ocean. Now extinct. Presumably inhabited freshwater wetlands and coastal areas before human colonization.
Mandarin Duck
Wooded lakes, rivers, and ponds surrounded by dense forest. Unlike most ducks, regularly perches in trees and nests in tree cavities.

About These Birds
Mauritius Duck
An extinct duck known from subfossil bones found on Mauritius and Réunion. Closely related to the Grey Teal. Went extinct after European settlement of the Mascarene Islands in the 17th century due to hunting and introduced predators.
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.
