Malagasy shelduck
The Malagasy shelduck, also known as the Sirabe shelduck, is an extinct species of waterfowl in the shelduck subfamily. It was described from subfossil bones found at Antsirabe in central Madagascar. Radiocarbon dating of subsequently discovered material shows that the bird survived to at least 1,400 years ago, after human settlement of the island. A close relative of the Egyptian goose, the bird is sometimes considered a subspecies of the extinct Mauritius sheldgoose; in this case it would become Alopochen maritiana sirabensis.
