The spots gave it away. Just like a human fingerprint, the rosette pattern on each jaguar is unique so researchers knew they had a new animal on their hands after reviewing images captured by a remote camera in southern Arizona.
The University of Arizona Wild Cat Research and Conservation Center says it’s the fifth big cat over the last 15 years to be spotted in the area after crossing the U.S.-Mexico border. The animal was captured by the camera as it visited a watering hole in November, its distinctive spots setting it apart from previous sightings.
“We’re very excited. It signifies this edge population of jaguars continues to come here because they’re finding what they need,” Susan Malusa, director of the center’s jaguar and ocelot project, said during an interview Thursday.
The team is now working to collect scat samples to conduct genetic analysis and determine the sex and other details about the new jaguar, including what it likes to eat. The menu can include everything from skunks and javelina to small deer.
As an indicator species, Malusa said the continued presence of big cats in the region suggests a healthy landscape but that climate change and border barriers can threaten migratory corridors. She explained that warming temperatures and significant drought increase the urgency to ensure connectivity for jaguars with their historic range in Arizona.
More than 99% of the jaguar’s range is found in Central and South America, and the few male jaguars that have been spotted in the U.S. are believed to have dispersed from core populations in Mexico, according to the U.S. Fish and Wildlife Service. Officials have said that jaguar breeding in the U.S. has not been documented in more than 100 years.
Federal biologists have listed primary threats to the endangered species as habitat loss and fragmentation along with the animals being targeted for trophies and illegal trade.
The Fish and Wildlife Service issued a final rule in 2024, revising the habitat set aside for jaguars in response to a legal challenge. The area was reduced to about 1,000 square miles (2,590 square kilometers) in Arizona’s Pima, Santa Cruz and Cochise counties.
Recent detection data supports findings that a jaguar appears every few years, Malusa said, with movement often tied to the availability of water. When food and water are plentiful, there’s less movement.
In the case of Jaguar #5, she said it was remarkable that the cat kept returning to the area over a 10-day period. Otherwise, she described the animals as quite elusive.
“That’s the message — that this species is recovering,” Malusa said. “We want people to know that and that we still do have a chance to get it right and keep these corridors open.”
