This is Nebraska's newest National Wildlife Refuge, established in 1992 on the inside bend of the Missouri River east of Fort Calhoun. Encompassing 3,300 acres, the Refuge contains significant acres of tallgrass prairie plus riparian timber, river and wetland areas, and cropland.
A breeding bird survey conducted in 2000 counted 69 breeding species, including northern bobwhite, red-bellied woodpecker, sedge wren, eastern wood-pewee, warbling and Bell's vireo, common yellowthroat, Baltimore and orchard oriole, and black- and yellow-billed cuckoo. Prairie uplands support significant numbers of dickcissels and grasshopper sparrows (the third and fourth most abundant species on the breeding survey), as well as other species like Henslow's sparrow, upland sandpiper, and horned lark.
The Refuge is managed by the U.S. Fish and Wildlife Service, an agency of the Department of the Interior.
