Mauritius Duck

The Mascarene teal, also known as the Mauritius duck and Sauzier's teal, is an extinct species of duck that lived on the Mascarene Islands of Mauritius and Réunion. A small duck was mentioned in 17th century accounts from these islands which is thought to be this species, and it may also be depicted in one illustration. In 1893, various bones from the Mare aux Songes swamp of Mauritius were used to name a new species in the duck genus Anas, A. theodori, after Théodore Sauzier who directed the excavations. Additional remains from Réunion were considered to belong to the same species in 1999, and it was determined to be related to the Sunda teal of the Indian Ocean.
