A century ago, the jaguar was found in the four states bordering Mexico--as far north as the Grand Canyon. However, it has been all-but-extirpated from this country via hunting and habitat loss. Jaguars are still occasionally seen in southern Arizona and New Mexico, but there's no known breeding population here. Recently, it seems that one of the greatest dangers to jaguars in or near the U.S. is researchers trying to study them.
In the last seven years, biologists have captured four jaguars in the Arizona-Sonora region, in each case intending to put a radio collar on the animal and follow its movements.

The animal never recovered from sedation and died as the warm morning turned hot. Rosas attributed the death to "heat stress."
Ugh. The animal had been trapped in a leg snare. The first ketamine dart didn't do the trick, but the second dart--a half-dose, sure did. The researcher was a PhD student from New Mexico State University.

They managed to sedate and collar the jaguar, who was released.
"Her health was good, and we made sure she was in good condition several weeks after capture," Avila said in a statement written this year.
Researchers discovered in October 2003 that the jaguar had slipped out of the collar.
A few months of data is better than nothing. And two days later, the same pair of biologists captured another jaguar.

The two biologists had already trapped mountain lions as part of the research, but they said in e-mails they were woefully unprepared for the jaguar capture. They used a blowgun and a "jab stick" to try to sedate the jaguar, which lunged at them.
They put a radio collar on the jaguar, but it died. McCain concluded that the heat of that day and the difficulty sedating the animal combined to cause the death.
Woefully unprepared?? Switching to a more detailed article on this debacle.
The biologists involved in the Mexican capture blamed their supervisor—a prominent researcher and published authority on jaguars—for failing to adequately prepare them for the capture.

Avila and McCain also wrote in their e-mails that Lopez Gonzales told them to keep the death quiet and to hide the cat's skin and skull at the ranch. Emil McCain skinned the jaguar, cleaned the skull and buried the body close to the ranch, Avila wrote.
Lopez Gonzalez denied telling the biologists to cover up the death but acknowledged that he didn't want them traveling anywhere with the jaguar corpse, saying he "didn't think he would be looked at very good in the towns."
Lopez Gonzalez said he notified Semarnat, the Mexican environmental agency, of the death, but agency representatives told the Star they could find no information about the 2003 jaguar capture.
Carlos Lopez Gonzalez is a Mexican research biologist at the Universidad de Queretaro. In the late '90s,
...Lopez Gonzalez started researching jaguars in Sonora while working on a book—published in 2001—with David Brown, an Arizona State University adjunct professor and a wildlife biologist for 40 years.
Lopez Gonzalez targeted the rough, steep, canyon-filled eastern Sonora terrain centering on Los Pavos, a 10,000-acre ranch in the thornscrub, 65 miles from the nearest town. His work drew support from 20 conservation groups and environmentalists, including Tucsonan Craig Miller of Defenders of Wildlife. Miller recently said he had long felt that if any hope existed for jaguars to recover north of the border, it had to start with protecting and recovering the far larger population in Sonora.
I agree, but not killing the jaguars already here also matters. Back to the original article.
Feb. 18, 2009: Between Nogales and Arivaca, Ariz
Arizona Game and Fish biologists Thorry Smith and Michelle Crabb were checking snares, set as part of a mountain lion and bear study, when they found a jaguar had been trapped.
...
Smith used an injection rifle to fire a dart containing the sedative Telazol into the old jaguar's rump, and after 13 minutes, the jaguar was quiet. The morning was cold and the cat's body temperature was cool. He looked healthy when released, but within days he was barely moving.
On March 2, a team recaptured the jaguar and took him to the Phoenix Zoo for treatment. There, a medical team diagnosed terminal kidney failure and euthanized him.
That cat--Macho B--had been first photographed in Arizona in 1996. Switching back to the other article...
Since Macho B's death, environmentalists have said the department did not learn the lessons of the earlier Sonoran jaguar deaths.
For one, there was no veterinarian or anyone with jaguar-capture experience on the scene at Macho B's capture, although the capture team had consulted with veterinarians on what kind of anesthetic to give a jaguar in the event of a capture. Because the trap that snared Macho B had no electronic signal, biologists didn't learn of the capture until three to 14 hours after it occurred.
The captors also used a snare trap even though a risk assessment done for the Jaguar Conservation Team had warned that was the riskiest of three possible methods of capture, instead advocating the use of hounds.
Game and Fish officials have said they did not take those steps because that was the protocol for deliberate jaguar capture—not for accidental capture.
Yeah, but why would one trap big cats in that area without being prepared for the possibility of snaring a jaguar? Meanwhile, environmentalists actually recommended using hounds to go after jaguars? And if the officials had used hounds, what would the environmentalists say they instead should have been doing?
