Quick Answer
Northern Shovelers seek aquatic plants and invertebrates such as snails and aquatic insects during late migration. They also feed on small crustaceans like crayfish and amphipods. Insects and grains such as rice and wheat may be consumed during times of scarcity.
Plant-Based Food Sources
During late migration, Northern Shovelers focus on eating various types of aquatic plants, including algae, duckweed, and submerged aquatic vegetation like coontail and waterweed. They can eat up to 1/3 of their body weight in aquatic plants daily, which is essential for their survival. In North America, they often feed on the dense vegetation found in marshes, ponds, and wetlands.
Invertebrate and Crustacean Food Sources
Invertebrates and small crustaceans make up a significant portion of a Northern Shoveler’s diet during late migration. They forage for snails, aquatic insects, crayfish, and amphipods in shallow water with dense vegetation or submerged structures. In the southeastern United States, for example, they often feed on snails and crayfish in freshwater wetlands.
Hunting and Habitat Considerations
When hunting Northern Shovelers, understanding their food sources and habitat preferences is crucial for success. Look for areas with dense aquatic vegetation, shallow water, and an abundance of invertebrates and crustaceans. In North America, these areas can be found in marshes, ponds, and wetlands. Consider using decoys, calling, or blind hunting techniques to increase your chances of encountering these birds during late migration.
