What Do Mallard Ducks Eat?
Posted In: Birds.
Mallard ducks will eat a variety of foods. This type of duck is considered to be omnivorous, which means it has a varied diet of plants, animals and other items. They feed at the surface of the water and are very flexible as to what they will eat. The diet is also going to be determined by not only the food available but also breeding cycle as well as competition between other species for the same food source. This particular duck is not limited to just one sort of diet, rather they have several different choices.
Invertebrates & gastropods
Mallards have a wide variety of choices when it comes to invertebrates such as flies, caddisflies, dragonflies, lepidopterans and beetles. Worms and crustaceans also round out the mallard diet in this particular classification. With such a variety of food available to them, they are able to find good food no matter where they are.
Tubers and roots
This is also a staple of the mallard diet. Roots and tubers play an important role in the nutrition of the Mallard. Bulrushes, hackberry, barley and roots of swamp trees make an important part of the mallard diet. Any roots or tubers that they can find are added to their diet.
Plant matter and seeds
Mallards also feed on the seeds that they find during foraging, as well as plant matter. Seeds in the diet include primrose, willow, oak, wild rice, wheat, corn and barley. They can also eat water elm seeds as well as other seeds that they find foraging.
Frogs and other animals
While some of the animals that mallards eat have already been listed above, they also eat frogs, small fish, insects, freshwater snails and fish eggs. So the diet is varied depending on location as well as what life cycle the mallard is in. Since they do not dive into the water like other birds, they can get more by tipping their heads under the water to feed themselves.
