In a rare sign of unity, hunting organizations and animal rights advocates are calling on states to ban the use of drones in big game hunting, which manufacturers see as a new market for the pilotless aircraft.

National conservation groups that promote hunting like the Izaak Walton League of America, the Pope & Young Club and the Boone and Crockett Club, and anti-hunting organizations like PETA and the Humane Society of the United States, are all asking states to discourage the use of drones to help hunters spot game such as elk, deer and sheep.
