Surface Ducks inhabit swallow bodies of water such as marshes, saltpans, lagoons, with a floating vegetation. Essentially migratory, they are sociable and gregarious ducks which favor mixed flocks. Surface Ducks have sober colors and fly slower than other ducks. They are nocturnal and crepuscular feeders and essentially omnivorous. Monogamous pair bonds are seasonal and initiate at the end of January in Arctic and temperate regions where they reproduce. Females actively participate in duckling care. Young are sexual mature at one year. Some of important Surface Ducks are: Northern Pintail (Anas acuta), Eurasian Wigeon (Anas Penelope), American Wigeon (Anas Americana), Green Winged Teal (Anas Crecca Crecca), Northern Shoveler (Anas Clypeata), Falcated Duck (Anas Falcata), Mallard (Anas Platyrhynchos), Gadwall (Anas Stretera), Garganey (Anas Querquedula), Blue-Winged Teal (Anas Discors), Red Shoveler (Anas Platalea) and Australasian Shoveler (Anas Rhynchotis).
