The Riverlands Migratory Bird Sanctuary is located at the heart of the Mississippi Flyway on the Mississippi River near its confluence with the Missouri River.  Over 300-plus bird species, including 60% of all North American birds and 40% of the nation's waterfowl find food, shelter, and safe passage on the Mississippi Flyway, one of the greatest migration corridors on the planet.  This 3,700 acre Riverlands Migratory Bird Sanctuary provides unmatched opportunities to view the birds and other wildlife and experience the majesty of the Great Rivers every season of the year. Frequent visitors include Bald Eagles and Trumpeter Swans in winter, migrating shorebirds and warblers in spring and fall, Dickcissel and other grassland birds in summer, and year-round residents like the Great Blue Heron.
