He is one of the oldest jaguars on record along the frontier, and one of few known to have crossed the U.S.-Mexico border, say ecologists.

jaguars they had lost track of might still be alive.

They were believed to have vanished from the United States by the turn of the century after being hunted for government rewards in the southwestern United States to encourage cattle ranching. The majority of the world’s jaguars can be found in four regions: the Pacific coast of Mexico, southeastern Mexico, central America, and central South America.

Studies conducted in response to a 1996 jaguar sighting in the United States located a key breeding area in central Sonora.

Non-governmental organizations in the U.S. and Mexico have collaborated to protect wild cats by monitoring their movements, establishing safe havens for them, and enlisting the help of landowners in both countries.

Drug cartels are a major obstacle for conservationists in Mexico, adding to the difficulty of figuring out where to place cameras to record the animals and analyzing the images later.

On the phone from Sonora, Bravo revealed that “there is a presence of armed groups and drug traffickers” in the remote areas frequented by the jaguars. “It is crucial that we proceed cautiously, cooperating with the locals who advise us against venturing into certain areas. Everything is getting way too complicated.

Walls erected at the border hinder the movement of jaguars, American antelope, black bears, and Mexican wolves, which poses the greatest threat to efforts to repopulate the American Southwest with jaguars, according to Bravo. He also mentioned that the Border Patrol’s light towers and the roads they use are problematic.
