A lone male wolf loped across the sandy landscape of the Chihuahuan Desert under a waning January moon in 2017, heading north. The male, known as M1425, was a member of a small population of endangered Mexican gray wolves reintroduced into Mexico in 2012.
The wolf was doing exactly what male wolves should be doing: exploring the landscape in search of new habitat, food sources and possibly even a mate. M1425 spent two nights exploring the new range before turning south and heading back to familiar territory.
The journey north, which took the wolf across the U.S.-Mexico border, was encouraging to researchers who tracked the animal’s peregrinations by GPS collar. Finding suitable mates has become a chief concern in the conservation of Mexican gray wolves, whose recovery has been stymied in part by lack of genetic diversity.
