A infamous jaguar that roamed the mountains of southern Arizona for a number of years earlier than disappearing in 2015 turned up greater than 100 miles south of Mexico, conservation biologists say.
The Mexican non-profit group Profauna mentioned this week that the large cat often known as El Jefe had been photographed in an undisclosed mountainous location in central Sonora as a part of the Border Hyperlinks Initiative. That program, which entails varied teams on either side of the border and run by the Wildlands Community, displays greater than 150 motion-sensing wildlife cameras within the area.
El Jefe, or “The Boss,” named for Tucson highschool college students, was photographed quite a few instances within the mountains south of Tucson at a time when it was the one confirmed jaguar to roam wild in the US. Two different males have since been photographed in Arizona, although each later disappeared, and one turned up poached in Mexico.
El Jefe’s lengthy journey north of the border made him a star amongst those that longed for the species’ return to its historic northernmost vary, and his obvious good well being in Sonora emboldened large cat conservationists.
“He is like an outdated buddy you have not heard from in a very long time,” mentioned Aletris Neils, who runs Conservation CATalyst, a Tucson-based group devoted to saving the world’s 38 wild cat species. “Simply realizing they’re okay warms your coronary heart.”
In early 2016, Conservation CATalyst and the Middle for Organic Range launched video of the final identified sighting of El Jefe, from the earlier fall within the Santa Rita Mountains.
The photographs captured in Sonora have been the primary confirmed sightings since then. A Northern Jaguar Mission researcher, Carmina Gutiérrez-González, confirmed the cat’s id from its noticed sample after software program first recognized a match.
“There is no such thing as a query that this is identical animal photographed in Arizona that many feared could have died when it stopped exhibiting up on path cameras almost seven years in the past,” Gutierrez-González mentioned in a Wildlands Community information launch.
A spokesperson for the Arizona Sport and Fish Division confirmed that division biologists had reviewed the pictures and agreed they’re the identical because the jaguar repeatedly documented within the Santa Rita and Whetstone ranges between 2011 and 2015.
Components of Arizona, together with the Sky Island forests, comprise the northernmost historic habitat for jaguars, which vary south by means of the Americas. The one jaguars identified to have roamed the state on this century have been males and it’s believed that they have been in search of their very own territories. Lastly, they may not discover a mate.

The Northern Jaguar Mission maintains a reserve within the Sierra Madre Occidental, a mountainous panorama comparatively wetter than Arizona’s, about 120 miles south of the border, the place a breeding inhabitants thrives. There, conservationists accomplice with ranchers in an effort to keep up a core inhabitants that may repopulate areas the place predators have been extirpated.
The species’ full-time return to Arizona faces a lot of obstacles, together with a border wall that has left just a few roads, such because the mountains of Patagonia and the San Rafael Valley. Conservationists additionally concern {that a} proposed copper mine within the Santa Rita mountains, El Jefe’s former territory, might deter colonization.
The US Fish and Wildlife Service initially decided that Hudbay’s Rosemont mine wouldn’t destroy crucial habitat for the endangered jaguar, however a federal choose overturned that call and ordered a brand new assessment. The corporate has appealed the ruling.
“I’m delighted to know that an enormous, stunning cat like El Jefe has traveled lots of of miles, crossed the border no less than twice, and gone nearly unnoticed for the final seven years,” mentioned Russ McSpadden, a conservation advocate on the Middle for Range. Organic. in a written assertion.
The truth that it apparently did so with out beforehand triggering a digicam within the area’s substantial community exhibits how troublesome monitoring these creatures could be, Neils mentioned. Her bodily situation at age 12 means that she has remained wholesome, which she interprets as an indication that the habitat she has traversed, together with in Arizona, supported her nicely.
American conservationists collected DNA from El Jefe’s droppings as he roamed Arizona. Someday, Neils mentioned, he hopes biologists will match the genes in a youthful jaguar, confirming that El Jefe’s admixture with the core inhabitants has led to profitable breeding.
