In Florida, mottled ducks are found in freshwater wetlands, ditches, wet prairies and flooded marshes. In some seasons, mottled ducks are also found in rice and flooded fallow fields. In some cases, they have been found in small numbers in mosquito control areas. They stay in the same area year-round.
In Texas and Louisiana, mottled ducks are found fresh and saltwater marshes and brackish ponds. These areas are full of vegetation such as bulrush, long grasses, rice, cutgrass and bultongue.
