Peering at a map of red dots, Michael Robinson became worried when he couldn’t locate AF1251, the last adult Mexican gray wolf of the Prieto pack, who was also a mother with a yearling.
Robinson, senior conservation advocate at the Center for Biological Diversity, was keeping an eye on the remaining two members of the Prieto pack after the alpha male of the pack and a pup had been killed by the federal Wildlife Services agents earlier this year. Wildlife Services is a secretive federal agency that offers predator removal services for ranchers.
The two wolf killings followed the removal of a total of seven pack members over the last two years.
“I’d been very interested in what would happen to the Prieto pack after [that],” Robinson said.
The mapping tool, provided by the U.S. Fish and Wildlife Service, tracks endangered Mexican gray wolves using radio collar data. The map is usually updated every two weeks, but amid the pandemic, the map hadn’t been updated in over a month. When it was finally updated this week, Robinson said he checked the numbers of each red dot on the map, hoping to locate the female. But she wasn’t there. After a series of unanswered phone calls to the Fish and Wildlife Service, he received the news. The nine-year-old female was dead, and the yearling had fled.
That was the end of the Prieto pack.
