Early European settlers brought firearm technology to waterfowl hunting in the Americas. In the late eighteenth century, market hunting of the goose and duck flocks of the Atlantic and Mississippi Flyways proliferated. Hundreds of bird species move along the Atlantic coast and from the headwaters of the Mississippi River in Minnesota and Ohio to the Gulf of Mexico, migrating between breeding grounds and wintering grounds, and in the nineteenth century, hunters began using sound to draw down these passing birds.
