Video shows only known wild jaguar in U.S.

A video released Wednesday by Conservation CATalyst and the Center for Biological Diversity shows the only known wild jaguar in the United States.

The footage shows the jaguar roaming in the Santa Rita Mountains just outside Tucson, Ariz., and 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.

Bugbee said they've 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 Macho B was euthanized in March 2009, according to the Center for Biological Diversity.
