The Rodrigues Turtle Dove was described in 1874, when it was already extinct; it is known from subfossil remains and from contemporaneous accounts.
The species disappeared sometimes between 1726 and 1761.

The Amirante Islands are a group of small coral islands in the so-called outher Seychelles southwest of the Seychelles main islands.
These islands were once inhabted by an endemic subspecies of the Madagascar Turtle Dove (Nesoenas picturata (Temminck)), which actually might even warrant species status.
The Amirante Islands Turtle Dove was apparently extirpated by direct hunting, because the birds were seen as a pest; the last individuals were seen in the 1950s.

The Mauritius Turtle Dove was described based on subfossil bones that were recovered from deposits on the island of Mauritius, where it lived sympatrically with the Mauritius Pink Pigeon (Nesoenas mayeri (Prevost)).
This species had rather robust legs and small wings and had a rather terrestrial lifestyle. [1]

This species was described in 1907, it is known from at least one contemporaneous account and from subfossil bones.
The species was somewhat similar to the Mauritius Pink Pigeon (Nesoenas mayeri (Prevost)) (see photo below) that is still found on the island of Mauritius.
