Mascarenachen kervazoi Cowles, 1994 The Réunion sheldgoose or Kervazo's Egyptian goose (Alopochen kervazoi) is an extinct species of sheldgoose from Réunion.

Apart from that, the species is only known from brief reports and subfossil bones, collected by British ornithologist Graham S.

As early as 1667, François Martin complained of unsustainable hunting.

The last record of the species is a 1709 listing of de la Merveille who stated that ducks and geese occurred "in quantity", but as Jean Feuilley had not listed waterfowl in his 1705 catalogue of Réunion's animals, de la Merveille's record is obviously based on obsolete hearsay information.

Thus, the last record of the species appears to be the report of Père Bernardin in 1687.
