Wildlife & Habitat

Native Prairie 512x219

The Tewaukon Waterfowl Production Areas (WPA) are filled with shimmering blue wetland jewels amongst green grasses and a variety of colorful wildflowers. These highly productive wetland and prairie habitats offer nesting and migrating habitat to over 245 bird species and a diversity of mammals and insects.

  • Blue-winged Teal

    Blue-Winged Teal Pair

    The blue-winged teal is the most common duck species to nest on WPAs in the Tewaukon Wetland Management District. It is a small duck that likes to nest in thick prairie grasses and forbs. It uses the variety of shallow wetlands on the District to feed and find safe cover for their ducklings.

    The blue-winged teal heads to Tewaukon in the later part of March and into April. They spend the springtime finding a suitable mate and the female looks for a good hiding spot to build a nest. Blue-winged teal nest on the ground amongst the dense grasses and forbs and lay between 6-13 eggs. After hatching, the young teal stay in the nest only one day before heading to the safety of deeper water with the hen.

  • Bobolink


    The bobolink is a bird that lives in the dense vegetation of the tallgrass prairie. The males are black with a white back and with a patch of yellow on the back of their heads. Their song is a bubbly, metallic series of beeps, twitters, and warbling. They sit on high perches in meadows but forage while walking on the ground. The female bobolink is brown with small black and darker brown coloration to help her blend into the grass as she hides her nest on the ground. Bobolinks are social throughout most of the year.

    This common prairie bird can be seen on WPAs with dense vegetation and no trees. These birds feed on some insects but mostly seed from the grasses and wildflowers. They can have a brood of 4-7 young and feed them small insects to help them grow quickly.

    In the fall, bobolinks head out in late August and early September for their wintering grounds in southern South America.
