El Jefe, North America's Last Jaguar, Caught On Video

New York: El Jefe, North America's Last Jaguar, Has Been Caught On Video.

Conservation CATalyst and the Center for Biological Diversity has released a video showing the the last known wild jaguar in the United States.

In the video, El Jefe, the big cat can be spotted roaming in the Santa Rita Mountains just outside Tucson, Arizona. The spotting of the jaguar is part of an ongoing camera project that monitors mountain ranges for endangered jaguar and ocelot, the Center for Biological Diversity said in a statement.

"Studying these elusive cats anywhere is extremely difficult, but following the only known individual in the U.S. is especially challenging," said Chris Bugbee, a biologist with Conservation CATalyst. The cat has been named El Jefe by Tucson students.

According to Bugbee, he and his colleague spent three years tracking the mountains. "These videos represent the peak of our efforts," he added.

El Jefe is the only 'verified' jaguar in America since the euthanisation of Macho B in March 2009, according to the Center for Biological Diversity.

AZ Central report said, "(El Jefe's) home range is ground zero for the Rosemont Copper mine," the center's Randy Serraglio said. "It's really going to destroy a significant part of his home."

"Jaguars have always occurred in Arizona and yet we know so little about them in the northern portion of their range," Bugbee, a biologist with Conservation CATalyst, said in a press release.

"Smack in the middle of his territory is a proposed copper mine. That not only has the potential to destroy his habitat, but it will also influence prey. This cat will have to relocate to in a different area where he might not be as successful," he added.
