Anseriformes is an order of birds also known as waterfowl that comprises about 180 living species of birds in three families: Anhimidae (three species of screamers), Anseranatidae (the magpie goose), and Anatidae, the largest family, which includes over 170 species of waterfowl, among them the ducks, geese, and swans.
This is a list of Anseriformes species by global population. While numbers are estimates, they have been made by the experts in their fields. Anseriformes (Anser being Latin for "goose") is the taxonomic order to which the ducks, geese, swans, and screamers belong.

The Anatinae are a subfamily of the family Anatidae (swans, geese and ducks). Its surviving members are the dabbling ducks , which feed mainly at the surface rather than by diving . The other members of the Anatinae are the extinct moa-nalo , a young but highly apomorphic lineage derived from the dabbling ducks.
The Anserinae are a subfamily in the waterfowl family Anatidae.It includes the swans and the true geese.Under alternative systematical concepts (see e.g., Terres & NAS, 1991), it is split into two subfamilies, the Anserinae contain the geese and the ducks, while the Cygninae contain the swans.
