caption_attribution_description: English: El Jefe the jaguar
context_page_description: El Jefe is an adult, male North American jaguar that was seen in Arizona. He was first recorded in November 2011, and is living in the Santa Rita Mountains. From November 2011 to November 2016, El Jefe was the only wild jaguar verified to live in the United States. His name - which is Spanish for The Boss - was chosen by students of the Felizardo Valencia Middle School of Tucson, in a contest organized by the non-profit conservation group Center for Biological Diversity in November 2015 and has been used frequently by conservation groups and media. However, several researchers involved in his monitoring prefer to call him simply the Santa Ritas jaguar.
