Investigating the Death of Macho B, America’s Last Known Wild Jaguar

A criminal investigation has been launched into the capture and death of Macho B, the last known wild jaguar in the United States. He was at least 15 years old, making him the oldest wild jaguar ever reported. He was first captured in a leg-hold snare outside Tucson, Arizona, on February 18. Described as healthy, he was tranquilized and fitted with a radio-collar by which he could be tracked by satellite, and released. On March 2, when wildlife officials decided he was in poor health, they recaptured him with tranquilizing darts and flew him to the Phoenix Zoo. He was euthanized at the zoo the very same day because a veterinarian said Macho B had irreversible kidney failure. Questions were soon raised about the circumstances of the incident. Macho B had been observed by remote cameras, but conservationists had argued that no attempt should be made to snare the animal, especially considering his age. The Arizona Game and Fish Department “did not authorize or condone intentional initial capture of this jaguar,” it said in a statement [The New York Times]. However, a biologist who was working as a consultant to the department, Emil McCain, may have instructed an employee to snare the jaguar. A field technician claims that McCain gave her female jaguar scat in February, and told her to place it at the snare trap site. The scat had been used several times to attract Macho B to come within camera range [The New York Times]. McCain has denied the allegation. Wildlife officials are also investigating whether stress from his capture had caused or exacerbated Macho B’s condition. A necropsy was performed, and [on March 4] Phoenix Zoo Executive Vice President Dr. Dean Rice [said] the capture probably played a key role in the jaguar’s death [Los Angeles Times]...Discover
