Reunion Shelduck

The Réunion sheldgoose or Kervazo's Egyptian goose is an extinct species of sheldgoose from Réunion. It was a close relative of the Egyptian goose and was about the same size. There is only one description remaining, that of Dubois made in 1674. Apart from that, the species is only known from brief reports and subfossil bones, collected by British ornithologist Graham S. Cowles. Dubois' full account reads as follows:

Wild geese, slightly smaller than the European geese. They have the same feathering, but with the bill and feet red. They are very good [to eat].
