So, what do mallard ducks eat? Mallard ducks eat plant matter, bugs, grains, and small fish. They are omnivorous, but particularly prefer plant matter over carnivorous options. But how much should a mallard eat per day, and what treats can you give your pet mallard duck to try out? Let’s learn about this common waterfowl now.
What Does a Mallard Duck Eat?
A mallard duck eats plant material from roots and leaves, seeds such as acorns, bugs and invertebrates, and even small fish. They are opportunistic eaters, weeding through tall grasses and riverbeds for their food. Mallards enjoy seeds greatly, according to Oecologia. The amount of seeds they eat and pass helps improve the spread of many different plant seeds. Mallards digest an average of 70% of the seeds they eat, leaving the remaining 30% undigested and capable of growing more plants from it. It is important to note that many breads are bad for mallards. While certain grains and Seed varieties are safe and recommended to feed your local duck pond, bread has the capability of carrying many bacterias and diseases that can harm local duck populations. It is more important to bring along fresh vegetables and produce with you if you want to feed your local ducks. Let’s take a look at some more complete list of what a mallard duck may enjoy eating.

Mallards are not very picky eaters. This is why you may be wondering why you can’t feed them your old moldy bread. It is important to note that just because a mallard duck seems excited about a certain food, it doesn’t mean that you should feed it to them. Mallards use their beaks to sift through plant matter and water in order to find their food. They enjoy pecking and hunting through grains and plant matter, much like many other species of bird. According to The Journal of Wildlife Management, mallard ducks often seek out invertebrates or bugs, especially during winter. They require some level of protein in their diets, though winter may make such foods difficult to come by. This is why many mallards eat plant matter as the majority of their diet. This includes seeds and corn, but primarily includes grass from farmlands or aquatic plants. They will even eat fish or other water invertebrates, but prefer plant matter over all things. Mallard ducks have also been known to eat fish eggs. Mallard ducks have been known to pass viable fish eggs through their digestive system, leaving baby fish alive and capable of living on!
How Much Does a Mallard Duck Eat?
A mallard duck eats anywhere from 70-120 grams of grain per day, according to the Wildlife Society Bulletin. The amount of food depends on the size of the mallard duck, their age, location, and whether it is a pet or a wild duck. Mallard ducks are often free grazers, eating whatever comes across their beaks. They dive for food often, sticking their feathered tails in the air as they bob on the water. It is important to pay attention to how much you are feeding your captive ducks, as they tend to eat whatever is put in front of them. But more on that later. Mallard ducks enjoy foraging on land, packing through grassland and dirt for bugs and seeds. They eat a lot of wasted grain, such as corn and husked oats or barley. The green headed male mallard ducks often get lost in large fields of plant matter. Mallard ducklings often eat more aquatic protein than grown ducks. This could be because they need to learn how to properly hunt, and diving for food is much more difficult than simply foraging on land. Plus, ducklings often need more protein when they are young.

Mallard ducks are one of the most commonly hunted ducks in the United States. They are a very common breed of duck, so this is not unheard of. Many hunting dogs are trained to hunt mallard ducks in particular. Mallard ducklings often fall victim to predators, given their limited abilities for escape. They can’t fly right away, and are very slow runners and swimmers at first. Grown mallards are also at risk to predators, but are more capable of flying away.
