One of the most extraordinary wildlife recovery stories in recent North American history first broke out in 1996, when rancher Warner Glenn captured the first photos ever taken of a wild jaguar in the United States of America. The encounter, which occurred while Glenn was hunting mountain lions near his home in the Arizona-New Mexico borderlands, was the first documentation of jaguars in the USA since the early 20th century. Subsequently, further sightings and the use of infrared camera traps in the region have revealed the regular occurrence of a handful of male jaguars in southern Arizona and New Mexico. All of these animals are long-range wanderers from the northernmost population of jaguars, a group of about 120 animals, which resides in Mexico’s Sonora region.
