The two divisions of the Port Louisa NWR are important to Iowa birds because of the habitat. Species such as Bald Eagles, Red-Shouldered Hawks, Barn Owl and King Rail have either nested or attempted to nest there, according to their website. Three or more species in the high conservation priority category have also been identified as nesting species. Some include the Prothonotary and Cerulean Warbler and American and Least Bittern. The habitat that is there is unique because it is maintained and supports this assemblege of birds. Each year large groups of waterfowl, shorebirds and songbirds can be found here during migration. This area is important for research, including future research opportunities.
