Part of the U.S. Department of Agriculture’s Animal and Plant Health Inspection Service (APHIS), the Wildlife Services (WS) program helps alleviate wildlife damage to agricultural, urban, and natural resources. WS also addresses wildlife threats to public health and safety and protects endangered and threatened species from predators. Canada geese, ducks, and other waterfowl are valuable natural resources enjoyed by birdwatchers and the general public. WS professionals recommend a number of methods to discourage waterfowl from settling in residential and crop areas. In special instances, WS may relocate urban waterfowl using live-trapping or tranquilizers such as alpha-chloralose.
