337 species of birds have been identified in the national lakeshore area. 113 of those species are considered regular nesters. The Bald Eagle and the Sandhill Crane migrate through the park. With habitat restoration and improving water quality in the area, it is hoped that they may nest again at the park in the next decade. There are 18 species of amphibians.
Surveys are underway to determine the status of populations of frogs.
27 species of reptiles can be found. Visitors to the foredunes and blowouts may catch a glimpse of the six-lined racerunner darting through the marram grass. The national lakeshore provides critical habitat for the Karner Blue butterfly, a federally endangered species.
