Located below the confluence of 3 of the greatest rivers in North America – the Mississippi, the Missouri, and the Illinois – and situated in one of the most important nature preserves in the area is the Audubon Center at Riverlands. The Center is located along one of the most significant migratory flyways in the world – the Mississippi Flyway. This flyway is significant because about 60% of all North American waterfowl and songbirds, approximately 325 species in all, migrate along this route. The Audubon Center at Riverlands was opened to engage and enlighten birders and nature enthusiasts. The Center is set in the 3,700 acres of the marsh and wetlands forest of the Riverlands Migratory Bird Sanctuary. Built in partnership between the National Audubon Society and the U.S. Army Corps of Engineers, the center features floor to ceiling windows that afford great views of the Mississippi River. Visiting Hours: Open Daily: 8 am – 4 pm. Closed on Thanksgiving Day, Christmas Eve Day, Christmas Day, New Years Eve Day and New Years Eve. The grounds are open from dawn to dusk daily. There is no charge to visit the Audubon Center at Riverlands.
