From 2 to 16 April 1993, we conducted road-side surveys of birds using harvested fields of small grains, soybeans, and wm within 8 km of two blackbird roosts in east central South Dakota. Blackbirds, waterfowl, killdeer, homed larks, ring-necked pheasants, and western meadowlarks were the most common buds recorded. The frequencies of blackbirds, non-game birds, terrestrial game birds, and waterfowl was not equally distributed within the three habitats (P = 0.U.23).
