The solitary feline, who has been nicknamed El Jefe, was picked up on camera in the Santa Rica Mountains.
Once a common sight across the Southwestern United States, jaguars were driven to the point of extinction back in the 1960s and have now all but disappeared from the wilds of America.
Only around four of five individuals have been spotted in the last 20 years, but now a sole survivor by the name of El Jefe has made a rare appearance on recently recorded trail camera footage.
The majestic animal, which is thought to have been living in mountains north of the Mexican border for over three years, is the only known wild jaguar in the entire United States.
