Audubon National Wildlife Refuge in North Dakota is a 14,739-acre prairie wetland refuge managed by the U.S. Fish and Wildlife Service, with most of its area covered by Audubon Lake. Established in 1955 as Snake Creek National Wildlife Refuge and renamed in 1967 for John James Audubon, it includes open water, islands, wetlands, and prairie habitat that support abundant wildlife. The lake’s 100 islands provide important bird nesting areas, and 3,020 acres of wetlands sustain many birds and mammals. Especially notable for Baird's sparrow and Le Conte's sparrow, the refuge documented 246 bird species between 1956 and 2007, highlighting its ecological importance.
