Because the jaguar is we never learned the spot pattern behavior, gained during more than 40 so deeply rooted in Latin American on his left side. Shortly before and years of experience following them culture, we began referring to this shortly after we last photographed in these remote mountain ranges, to jaguar as “Macho A.” “Macho” being Macho A, our cameras obtained two predict the most likely places to find the Spanish word for “male” and “A” photographs of the left profile of a jaguar. These pictures could either be Photos © Emil McCain. the left unknown side of Macho A or a different, unknown jaguar. Without a simultaneous photograph from both sides (paired cameras) we cannot be sure. Emil McCain, a Humboldt State University graduate student, joined the project in June 2004. He added several years of jaguar research experience gained in Costa Rica and Sonora, Mexico. Emil soon expanded the project three-fold. Camera captures soon expanded exponentially. We now have more than 15,000 images of 25 of the region’s wildlife species, including more than 70 photographs of jaguars. On August 31, 2004, we photographed another adult male jaguar in the same mountain range as Macho A. This jaguar had a distinctly different spot pattern. On his right side was a conspicuous rosette resembling the cartoon character “Pinocchio.” Being the second jaguar on our study, he became “Macho B.” Ever since the project began, we hoped to find the original 1996 jaguar again. Finally our wish came true. One spring day in 2006, we were reviewing our old photos of the jaguar we first treed in 1996 and realized what we hadn’t comprehended before. Winking at us through the juniper branches was the familiar face of Pinocchio. The jaguar which glared down at us from the tree that day was Macho B; our beautiful Baboquiviri jaguar is still here 10 years later! Those original photographs of

The data shows a diversity of life capable of supporting a jaguar population. Pictured are a jaguar (right), black (lower left), ringtail (lower right), and (bottom). Photos © Emil McCain.
