FARGO, N.D. (AP) – A western North Dakota outfitter who was arrested after shooting at a bald eagle decoy has pleaded guilty to a charge he attempted to kill a migratory bird.

Gary Stang, 63, was arrested in March near his hunting excursion business, the same day investigators with U.S. Fish and Wildlife Service set up the stuffed eagle decoy as a way to lure him into shooting it.

Agents had been investigating Stang for four years as a suspect in the shootings of protected birds like eagles, owls and hawks in an area near his business. Agents wouldn’t give a number on how many birds he’s suspected of killing.
