Abstract: A bird and mammal survey was conducted on 10 dike systems in the Lower Mississippi River (river miles 377 to 885, AHP) in the late summer and fall of 1984 as part of the Mississippi River Commission Lower Mississippi River Environmental Program. The totals recorded during the 3-month survey were comprised of 126,612 birds in 92 species and 599 mammals in 11 species. Results of the survey indicated frequent use of these areas by migrating and resident populations of birds. Mammals did not use the dike systems to any great extent. Greater numbers of birds and mammals were noted at dike systems containing open areas interspersed with woods and pools. Monthly bird concentrations were strongly influenced by migrants, especially swallow and blackbird species. These two categories constituted approximately 90 percent of the total bird observations. Large dike systems, such as Redman-Robinson Crusoe, Island 62, and Ashport-Golddust, provided large acreages and habitat diversity, which in turn resulted in greater numbers of sightings throughout the survey.
