El Jefe is an adult, male North American jaguar that was seen in Arizona. He was first recorded in the Whetstone Mountains in November 2011, and was later photographed over several years in the Santa Rita Mountains. From November 2011 to late 2015, El Jefe was the only wild jaguar verified to live in the United States since the death of Arizona Jaguar Macho B in 2009. According to "Notes on the Occurrences of Jaguars in Arizona and New Mexico", an article regarding jaguars in the Southwest US, "Sixty two jaguars have been reportedly killed or captured in the American Southwest since 1900." He was not seen in Arizona after September 2015 and it was presumed that he returned to Mexico, where the nearest breeding population of jaguars is located. This was confirmed almost seven years later in August 2022, when a collective of conservation groups announced that he had been photographed using a motion-detecting camera, on November 27, 2021, in the central part of the state of Sonora. ...
