Endangered Wolves Taste

FILE - in this Wednesday, Dec. 7, 2011, photo, a female Mexican gray wolf looks to avoid being captured for its annual vaccinations and medical checkup at the Sevilleta National Wildlife Refuge in central New Mexico. Biologists are trying to tap into the biological avoidance response in Mexican gray wolves so they will steer clear of livestock. Cattle depredations throughout southwestern New Mexico and southeastern Arizona have served as an Achillesí heel for the federal governmentís efforts to return the endangered species to its historic range throughout the American Southwest.(AP Photo/Susan Montoya Bryan)
