High Quality Content by WIKIPEDIA articles! The Egyptian Goose is a member of the duck, goose and swan family Anatidae. It is in the shelduck subfamily Tadorninae, and is the only extant member of the genus Alopochen. mtDNA cytochrome b sequence data suggest that the relationships of Alopochen to Tadorna need further investigation. Two or three species of Alopochen from the Madagascar region have become extinct in the last 1000 years or so: Mauritian Shelduck, Alopochen mauritianus - Mauritius, late 1690s. Malagasy Shelduck or Madagascar Shelduck, Alopochen sirabensis - Madagascar, prehistoric: see Late Quaternary prehistoric birds. Réunion Shelduck or Kervazo's Egyptian Goose, Alopochen kervazoi - Réunion, c.1690s
