Lobo was a North American gray wolf who lived in the Currumpaw Valley (Corrumpa Creek[1]) in New Mexico. During the 1890s, Lobo and his pack, having been deprived of their natural prey such as bison, elk, and pronghorn by settlers, became forced to prey on the settlers' livestock to survive. The ranchers (at Cross L Ranch[2]) tried to kill Lobo and his pack by poisoning animal carcasses, but the wolves removed the poisoned pieces and threw them aside, eating the rest.
