Genus
Anas (Mallards, pintails, and allies)
Anas is a genus of dabbling ducks. It includes the pintails, most teals, and the mallard and its close relatives. It formerly included additional species but following the publication of a molecular phylogenetic study in 2009 the genus was spit into four separate genera. The genus now contains 31 living species. The name Anas is the Latin for “duck”.
