Trumpeter Swan – Great Lakes Habitat

Trumpeter Swans breed in freshwater marshes, ponds and lakes. They require large areas of shallow water (one to three feet deep) that produce the vegetation required for nesting and food. Their diet consists of tubers and stems from aquatic plants, including arrowhead, pondweeds, sedges and bulrush; they’ll also eat grasses and grains. Preferred nesting sites range from six to 150 acres in size, and are located in isolated areas away from human disturbance.
