The United States Department of Agriculture (USDA) took responsibility for hundreds of dead starlings that were found on the ground and frozen in trees in a Yankton, S.D., park on Monday.
The USDA's Wildlife Services Program, which contracts with farmers for bird control, said it used an avicide poison called DRC-1339 to cull a roost of 5,000 birds that were defecating on a farmer's cattle feed across the state line in Nebraska. But officials said the agency had nothing to do with large and dense recent bird kills in Arkansas and Louisiana.
