North Dakota Century Code Title 20.1. Game, Fish, Predators, and Boating § 20.1-12-06. Game birds to be tagged

Each shooting preserve operator shall tag all game birds harvested by guests before the birds are consumed or removed from the shooting preserve premises. The director shall provide tags to shooting preserve operators, at nominal cost to them. Once affixed, tags must remain attached until the game birds are prepared for consumption. If a wild upland bird of the same species hunted on the shooting preserve is taken accidentally by a client out of the regular hunting season proclaimed by the governor, or is taken by a client not in possession of a proper small game license, the client may keep the bird. At no time following release may a shooting preserve operator allow the number of wild and released birds harvested to exceed one hundred percent of the number of birds that have been released. All birds must be healthy when released. The total percent of harvested wild birds kept by clients may not exceed twenty-five percent of the birds harvested during the season. Other than those wild birds allowed to be retained by a client, the shooting preserve operator shall deliver to the department all wild birds harvested.
