The LA Times has had good coverage of Macho B’s collaring and here’s a little more from them. Poor guy looks a bit wasted in this pic! In addition KOLD (CBS station in Tucson) has this on their website: ”

Arizona Game and Fish wildlife managers are learning some fascinating things about a jaguar roaming Southern Arizona.

They put a satellite tracking collar on the jaguar last week and it provides the cat’s location points every three hours.

It also has a unique feature with a special signal to indicate if the jaguar crosses the international border with Mexico.

Since it was collared February 18, the jaguar has moved several miles to a very high and rugged area. 

He has stayed in that general vicinity for a few days with patterns of rest and visits to a nearby creek.

Scientists also have confirmed that this cougar [WTF, guys he’s a jaguar!] is indeed “Macho B,” the same cougar that has been photographed by trail cameras periodically over the past 13 years.

Macho B is believed to be the oldest known jaguar in the wild, somewhere around 15 or 16″


Here’s info from The AZ Republic in Phoenix:

Scientists beginning to get info from tagged jaguar

Scientists are beginning to learn the lifestyle of the oldest known wild jaguar as it roams through southern Arizona.

The cat was captured last week and fitted with a tracking collar to allow scientists to learn more about the little-known, solitary species.

The Arizona Game and Fish Department has recorded the jaguar traveling several miles in the last week. The cat has mostly stayed near a very high and rugged area in southern Arizona.

The animal has remained in that area for a few days with apparent patterns of rest and visits to a nearby creek.

Since the collaring late last week, the cat has appeared to feed on prey.

Biologists have also confirmed the identity of the jaguar as Macho B, an older male cat that has been photographed periodically over the last 13 years. Macho B is believed to be the oldest known jaguar in the wild, at about 16 years old.

Previously, the oldest known jaguar was thought to be 13 years old.

Biologists are able to study the 118-pound male cat’s diet and feeding habits through the satellite tracking technology.

The GPS tracking collar provides location points for the cat every three hours, according to the press release.

The collar weighs less than 2 pounds and should not impede his normal movements or his ability to catch prey.

North Star Science and Technology donated the device, which was specifically designed for a jaguar in the event the species was captured.

The species has been listed in the United States under the Endangered Species Act since 1997, when their presence became known in the Arizona and New Mexico borderlands.

The Phoenix Zoo’s jaguar, Lucero, and Macho B are both Northern jaguars. Lucero was rescued after being illegally captured in Mexico. The Mexican government authorized a one-year loan of the cat to the Phoenix Zoo to allow for critical dental surgery, according to Lauren Strait, communication specialist at the Phoenix Zoo.

Strait said that tracking Macho B is a significant breakthrough because there is so little research on these animals. The tracking of Macho B and his foraging patterns will be highly beneficial to the study of the jaguar species.

Macho B was captured and collared on Feb. 18 in an area southwest of Tucson in a research study aimed at monitoring mountain lions and black bears.

Officials estimate that there are 70-100 jaguars left in the wild that are close to the United States, while about 3,000-15,000 remain wild worldwide. Jaguars are also the only cats in North America that roar
