Justification of Red List Category
This species was found on Mauritius, but is now Extinct having not been recorded since 1696. Hunting is likely to have caused its extinction.
No extant population remains.
Anas theodori was endemic to Mauritius, and is known from a number of explorers' accounts (Cheke 1987), and bones (Cowles 1987). Although in 1681, the gray teal was found in great numbers it was becoming rare by 1693, and was last mentioned as extant in 1696. There are also numerous travellers' 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 (Cheke 1987).
Reports indicate that it was found on lakes and ponds in the woods.
It was presumably hunted to extinction.
