Ducks Unlimited (DU) is an American nonprofit organization 501(c) dedicated to the conservation of wetlands and associated upland habitats for waterfowl, other wildlife, and people. It had roughly 700,000 members as of January 2016. In 1927, an offshoot of the Boone and Crockett Club was created specifically for sport bird management and operated until 1930 as the American Wild Fowlers. Membership included such people as Arthur Bartley and Nash Buckingham, who would later be very instrumental in the conservation movement. In 1930, Joseph P. Knapp, a publishing tycoon who successfully obtained such notable publications as The Associated Sunday Magazine, Crowell Publishing Company, Collier’s Weekly, Farm and Fireside and the book publisher P.F. Collier & Sons, founded More Game Birds in America and American Wild Fowlers was quickly absorbed into the new organization. In 1937, Knapp, Robert Winthrop, and a small group of conservation philanthropists decided to focus on the decreasing waterfowl populations, and the habitat necessary to sustain them in Canada, and formed Ducks Unlimited Inc. As had happened before, More Game Birds in America was absorbed by the new waterfowl organization.
