Great River National Wildlife Refuge is centrally located along the Mississippi Flyway, a major migration route for migratory birds, affording visitors an excellent opportunity to see wildlife. More than 200 species of birds visit the refuge throughout the year. Bald eagles are common in the winter as they gather near the river to feed in open water areas. Herons and egrets are seen during the summer feeding along the shores and in the wetlands. Deer, squirrel, raccoon, muskrat, otter, turkey, beaver, skunk, and opossum are year-round residents.
