Since 1999, the United States Department of Agriculture Wildlife Services agency has been engaged in lethal culls of Canada geese primarily in urban or densely populated areas. The agency responds to municipalities or private land owners, such as golf courses, which find the geese obtrusive or object to their waste. Addling goose eggs and destroying nests are promoted as humane population control methods. Flocks of Canada goose can also be captured during moult and this method of culling is used to control invasive populations.
