Pygargue à tête blanche
Crescent Lake NWR was protected in 1931 to ensure the wetlands would continue to be protected, providing migratory bird species and other animals a safe haven. As many as twenty Bald eagle pairs have been known to spend part of the year within the refuge, and along another 200 observed bird species, the refuge is considered one of the finest in the U.S. for birders. The grasses support a large group of Pronghorn as well as Mule and White-tailed deer. Coyote, bobcat, beaver, river otter, swift fox, prairie dog and raccoon are also found on the refuge. Sport fishing is popular with Yellow Perch, Walleye and Largemouth bass being the more commonly sought.
