Mallard (Anas platyrhyncos) can be found in a variety of wetland habitats. The species will migrate through the area in the early spring and late fall, usually pushing the “iceline”. They are a hardy species that will migrate into the Prairie Pothole Region before the lakes and ponds melt for the spring and stay until they start freezing up in the fall. Abundant breeding can be observed in the area dependent upon late spring wetland conditions. They breed in the adjacent upland grasses surrounding wetland complexes in the prairie.
