There are also numerous travelers' reports of sarcelles and canards from Réunion, and so presumably this or a similar species also occurred there, where they were extinct by 1710 at latest, although no bones have been found.

Hi ! As far as I know Anas theodori is indeed known from bones, from Mauritius and also from Reunion.  |

Mauritian Duck Anas theodori was endemic to Mauritius, and is known from a number of explorers' accounts, and bones. In 1681, the "gray teal" was found in "great numbers" on lakes and ponds in the woods, but it was presumably hunted to extinction, becoming rare by 1693, and last mentioned as extant in 1696. There are also numerous travelers' reports of sarcelles and canards from Réunion, and so presumably this or a similar species also occurred there, where they were extinct by 1710 at latest, although no bones have been found. www.redlist.org/search/details.php?species=1244 |

 Extinct birds : an attempt to unite in one volume a short account of those birds which have become extinct in historical times : that is, within the last six or seven hundred years : to which are added a few which still exist, but are on the verge of extinction (1907) |

The Mauritian Duck or Sauzier's Teal (Anas theodori) is an extinct dabbling duck that formerly occurred on the islands of Mauritius and Réunion. It was a small teal of the Anas gibberifrons superspecies of the Anas subgenus Nettion. Its closest relative is Bernier's Teal from Madagascar, and apart from having stronger wings and being considerably bigger (between a Sunda Teal and a mallard in size) it seems to have looked very similar to that species. Apart from a few, brief descriptions, not much is known about the bird in life, but its habits probably did not differ significantly from those of its close relatives. Bones have been found on Mauritius and more recently on Réunion also. The scientific name honors Thé́odore Sauzier, who made many bones of extinct birds found on Mauritius available to science. Extinction The bird became extinct on both islands almost simultaneously and for the same reason: overhunting. On Mauritus, the "grey teals" were found in "great numbers" in 1681, but in 1693, Leguat (1708) found "wild ducks" to be already rare. In 1696, governor Deodati mentioned the species for the last time to be extant. On Réunion, the species is last mentioned to occur "in quantity" in de la Merveille's 1709 listing of the island's wildlife, but as Feuilley had not listed waterfowl in his 1705 report, de la Merveille's record is obviously based on obsolete hearsay information. The last reliable record of the species appears to be the report of Père Bernardin in 1687; thus, the date of extinction can be assumed to be the late 1690s on Mauritius, and a few years earlier on Réunion. The reports of Bernardin and (1710) Boucher are puzzling insofar as that they mention both geese, sarcelles (teals, this species) as well as canards (ducks, larger than sarcelles) as occurring or having occurred on Réunion. It is possible that a carpometacarpus bone apparently of an Aythya diving duck is referrable to these canards. If so, these birds were probably related to the Madagascar Pochard, which seems to have gone extinct in the last decade of the 20th century. References * BirdLife International (2004).
