The Lake Ogallala State Recreation Area (LOSRA) is located immediately downstream from Lake McConaughy, which was formed by the construction of Kingsley Dam across the North Platte River, and includes riparian woodland, shrubland, grassland, marsh, sandbeach, rivers, ponds, and lakes. Birds were surveyed in LOSRA from 1988 to 1992 and censused in the southwest campground of LOSRA from late May to mid-July during the 1991 and 1992 breeding seasons. Seventy-five bird species (56 terrestrial and 19 aquatic) were observed, including several hybridizing species. Thirty-one terrestrial species inhabited the southwest campground, but only 60% of these were counted during biweekly censuses; a consistent set was not counted. Total bird abundance declined during the 10 week census periods. Three avian nest predators and one brood parasite were observed in the southwest campground. Species diversity decreased as survey area decreased.
