Depends on the duck. But yes, most Sea ducks (Long-Tail, Scoter, Eider) are eating bivalves, invertebrates, and crustaceans. Divers have a similar diet in salt water. Puddlers are a little bit more restricted to the coastal areas because of the way they feed, but will eat the same foods plus aquatic vegetation. What you run into with trying to plant anything in a brackish environment is the salinity of the soil and water. One of the best foods in such an environment is Widgeon Grass. And yes, Widgeon along with other puddlers eat it regularly when it is available. You can propagate the grass, but I would be concerned with its ability to take over any small body of water or area where there is no current. Other plants that can tolerate high salinity are Turtle weed (Batis maritima
), Inland Saltgrass (Distichlis spicata
) and Needlegrass Rush (Juncus roemerianus
) these would probably be your best bet if you have an area that you can only flood with saline water because they have a high saline tolerance.
