What They Eat Mallards eat weeds, roots, and seeds, as well as some mollusks, insects, small fish, tadpoles, freshwater snails, fish eggs, insects and insect larvae. On land, they eat grain. Mallards are dabblers. They can reach food in water a foot or two deep by tipping-up with their tails held vertically. Although they can dive in an emergency, they rarely do so.
Mallards live throughout North America, Europe, and Asia.
They can be found across Canada - they are most numerous in the Prairie Provinces, but recently they have been spreading eastward and northward. Mallards have adapted well to changing habitats and, as we can see, thrive even in major city centres. Most Mallards migrate to the central and southern United States in the winter, where lakes and ponds are ice-free, but some winter in southern parts of Canada.
