Whistling for the Jaguar

The un-redacted story of the jaguar, Macho B's snaring and death.

The effectiveness of jaguar scat

Contrary to what McCain told me, the jaguar scat he obtained from the Phoenix Zoo and had directed me to place at BJDP cameras and near the AZGFD snare that trapped Macho B was not from a female jaguar in estrus. According to Stuart Wells of the Phoenix Zoo, whom supplied the scat to McCain, the scat was from both the female and male jaguars housed at the zoo and the female was not in heat during the scat collection. It wasn’t until days after McCain received the scat that Wells thought the female had just come into heat because the male jaguar had begun “mewling” at her.

During the criminal investigation, the USFWS Special Agents tasked the USFWS “Jaguar Lead,” Erin Fernandez to investigate the effectiveness of jaguar scat as a scent lure and how that related to the “take” of Macho B. Fernandez reviewed eight studies that used attractants and two of those concluded that the scent lures had no long range effect but were effective to hold the animal in front of a camera long enough to obtain a better photo. Fernandez told the USFWS SAs that, “although jaguars have well developed olfactory organs, there was little published information on the olfactory ability of jaguars.” Fernandez stated, “she did not think that scat would have a long distance effect.”

With regards to using jaguar scat as a scent lure and if that met the criteria for a “take” violation of the Endangered Species Act Fernandez was uncertain. She explained there was too little known about Macho B and when the scat was used in relation to his detections in southern Arizona. If a case for a “take” violation could be made Fernandez suggested the use of jaguar scat as a scent lure could meet the definition of “harass” under the “take” violation of the Endangered Species Act.

Ron Thompson of AZGFD and McCain’s perceived boss on the snaring project also told the USFWS SAs that “there are no published studies on the effectiveness of scat for lions and jaguars.”
