Once driven to the brink extinction in the United States, the population of Mexican wolves has doubled in the past five years.
There were at least 109 wild Mexican wolves, or lobos, in the Southwest in 2014, up from 83 in 2013, U.S. Fish and Wildlife Service (FWS) announced Friday (Feb. 13). It's the fifth year in a row the small population has grown. In 2010, there were just 50 Mexican wolves in the wild.
