Million Of Geese, Missouri, United States

• The South American sheldgeese, genus Chloephaga
• The prehistoric Madagascar Sheldgoose, Centrornis majori, the "Woodard"
The Blue-winged Goose, Cyanochen cyanopterus belongs either to these, or to lineage closer to ducks.
The Spur-winged Goose, Plectropterus gambensis, is most closely related to the shelducks, but distinct enough to warrant its own subfamily, the Plectropterinae.
