While shortcomings certainly occur in Livezey's analysis, [citation needed] mtDNA is an unreliable source for phylogenetic information in many waterfowl (especially dabbling ducks) due to their ability to produce fertile hybrids, [2] in rare cases possibly even beyond the level of genus (see for example the "Barbary duck").
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.

Order: Anseriformes Family: Anatidae The family Anatidae includes the ducks and most duck-like waterfowl, such as geese and swans. These birds are adapted to an aquatic existence with webbed feet, bills which are flattened to a greater or lesser extent, and feathers that are excellent at shedding water due to special oils.
Following the 2010 Deepwater Horizon oil spill in the Gulf of Mexico, Ducks Unlimited became involved with multiple clean-up efforts in Gulf states. The organization worked with the National Fish and Wildlife Foundation and the USDA Natural Resources Conservation Service to protect approximately 79,000 acres of waterfowl and other waterbird habitats.

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.
A 1696 sighting by William de Vlaming of "four-footed animals" in the reeds of Amsterdam Island may have been of this duck, as there are no native land mammals on the island. [3] No naturalist visited Amsterdam Island until 1874, by which time it was infested with rats from visiting ships, and the duck was extinct. [4]
