The old oxbows and low-lying fields along Tippo Bayou flood each winter and attract large concentrations of waterfowl. Wood ducks abound here. The unit also has a very healthy deer herd. Peregrine falcon, bald eagles, merlin, least tern, black tern and wood stork occasionally pass through the refuge in migration. Eastern screech owls, barred owls, great horned owls, loggerhead shrikes, and red-tailed hawks are common year-round residents. Blue grosbeaks, dickcissels, and painted buntings can be seen during the summer months. Most of the agriculture land of the area is devoted to raising soybeans and rice, for the benefit of waterfowl. The refuge is complemented on the south by the Malmaison Wildlife Management Area managed by the State of Mississippi.
