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.
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 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. Thirty-nine species have been recorded in Connecticut. Upland sandpiper, Bartramia longicauda

The gadwall is a bird of open wetlands, such as prairie or steppe lakes, wet grassland or marshes with dense fringing vegetation, and usually feeds by dabbling for plant food with head submerged. They can also dive underwater for food, more proficiently than other dabbling ducks, and may also steal food from diving birds such as coots. [ 15 ]
