About These Birds
Mauritius Shelduck
An extinct shelduck formerly endemic to Mauritius. Known from subfossil bones and historical records from the 17th century. Likely resembled the Egyptian Goose. Went extinct after European colonization due to hunting and introduced predators. No description of living birds exists.
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.
