Arizona Captures and Collars the First Jaguar in the United States
An endangered species, jaguars used to roam a large part of the southwest, but were killed off by ranchers by 1972. Then in 1997 scientists started seeing pictures of two male jaguars. Macho A hasn't been spotted in a while and may be dead. Macho B weighs a healthy 118 pounds and is thought to be 15 or 16 years old. The oldest known wild jaguar was 13.
The small population of jaguars that lives in the Mexican state of Sonora, Arizona and New Mexico is cut off from the rest in Mexico. According to the Nature Conservancy, jaguars are the least studied of all the big cats, but governments are working to get ranchers who might kill the cats interested in keeping them by paying $500 for photos of jaguars living on their land.
