Mareca is a genus or subgenus of ducks in the family Anatidae that includes the wigeons.. The species now placed in this genus were formerly placed in the genus Anas.A molecular phylogentic study comparing mitochondrial DNA sequences published in 2009 found that the genus Anas, as then defined, was not monophyletic.

The Eurasian wigeon is a bird of open wetlands, such as wet grassland or marshes with some taller vegetation, and usually feeds by dabbling for plant food or grazing, which it does very readily. It nests on the ground, near water and under cover. It is highly gregarious outside of the breeding season and will form large flocks.
The American wigeon was formerly called the baldpate by ornithologists, and some people still use that name, especially hunters. The diet of the wigeon consists mainly of grass leaves (~80%), other food types eaten are seeds (~10%) and roots and stems (~5%).

The majority of these species eat small invertebrates picked out of the mud or soil. Different lengths of legs and bills enable multiple species to feed in the same habitat, particularly on the coast, without direct competition for food.

The gadwall was first described by Carl Linnaeus in his landmark 1758 10th edition of Systema Naturae. [3] DNA studies have shown that it is a sister species with the falcated duck; the two are closely related to the three species of wigeons, and all of them have been assigned to the genus Mareca.
