of U.S. Fish and Wildlife ServiceA photo taken by trail camera in February shows wandering wolf OR-7, at left, for the first time since his tracking collar quit working in 2015. He's the best known disperser from the influential Imnaha Pack of Northeast Oregon. OR-7 gained a national following when he left his home pack in 2011 and ventured into California. He's now alpha male of his own group, the Rogue Pack.
