The Passing of a Titan

Contrary to popular belief, mountain lions are not all the same. They are as distinctive in personality as we are. Some are bold, others stick to the shadows. Some are social, others avoid interactions. Some hunt elk, some prefer smaller fare. Some are productive, successful mothers that rear numerous kittens to young adults, and others…

Understanding Dogs to Protect Cats

Post submitted by Matthias Fiechter Feral dogs have been seen chasing snow leopards and bears away from their prey. Growing populations of free-ranging dogs are becoming a real threat to wildlife in many parts of the snow leopard’s range. Liu Mingyu, a researcher in China, is tracking dogs with GPS collars to better understand their behavior…

Solitary Is Not Asocial: Social Interactions Among Mountain Lions

On May 5, 2012, the way I—and many other scientists—understood mountain lions changed forever. A few days earlier, data collected from F57, an adult female mountain lion we’d captured as part of Panthera’s Teton Cougar Project just the month before, revealed that she’d been in the same place for two full days, behavior typically indicative…

Urgent Global Action Needed to Stop Extinction of Earth’s Last Megafauna

A swift and global conservation response is needed to prevent the world’s gorillas, lions, tigers, rhinos, and other iconic terrestrial megafauna from being lost forever, an influential group of international scientists reported today in the journal BioScience.

Their analysis, entitled Saving the World’s Terrestrial Megafauna, covers the precipitous loss of large animal populations around the globe. The report included a 13-point declaration by 43 scientists and conservationists calling for acknowledgement that a “business as usual” mentality will result in massive species extinction. Read the declaration and study the maps showing the global decline of big land animals.

Why Research Matters to Mountain Lions in Wyoming

Mountain lions live like shadows around us, and most people have never seen one. Most never will. Yet on July 8, the Wyoming Game Commission granted these wraiths of forests and mountains a reprieve in several parts of the state, including Unit 2 in the northwest where Panthera’s Teton Cougar Project (TCP) operates. Unit 2…

Short Film: The Secret Life of Mountain Lions

The “Secret Life of Mountain Lions” provides an intimate glimpse into the family lives of mountain lions. This true story follows F61, an adult female mountain lion, and one litter of kittens. Mountain lions have long been considered anti-social creatures, but this remarkable short film reveals a family that is playful, affectionate and interdependent, even…

A Win For Wyoming People and Mountain Lions

I’m thrilled to share that Wyoming legislature voted yesterday in favor of science and to protect the balance of nature on which our state so deeply depends. HB0012, which would have allowed the trapping of mountain lions in Wyoming, failed to pass the House on Tuesday, February 9, 2016 at 2:23 pm. Thank you to…

NatGeo Wild’s Big Cat Week: Cougars Undercover

Its Big Cat Week on NatGeo Wild, and one of the headliner films is Cougars Undercover, a dramatic film following the lives of two mountain lion families in northwest Wyoming. The stars of the film are F51 and F61, adult female mountain lions studied by Panthera’s Teton Cougar Project, an ongoing work addressing diverse ecological…

Overlapping Mountain Lions

F61 and F51, adult female mountain lions (Puma concolor), also called cougars, followed by Panthera’s Teton Cougar Project were both four years old when they gave birth to their first litters of kittens within a month of each other in 2011. The pair of big cats were neighbors in adjacent and overlapping home ranges in…

Mountain Lion Dispersal

M80 and F96, young mountain lions followed by Panthera’s Teton Cougar Project, dispersed from their mother’s home range in northwest Wyoming, about April 1st, 2014, when the pair were 19 months old. In northern climates, there is a Spring pulse of young mountain lions setting out to find territories of their own. M80 moved north…

A Fortress For Cougar Kittens

We suspected F47, an adult female mountain lion followed by Panthera’s Teton Cougar Project, was pregnant in Spring of 2013; during the winter, we had caught her on camera consorting with M85, the resident male that overlapped her territory (see Rare Video Footage Shows the Dynamics of Cougar Courtship). In late Spring, F47 began to…

Mountain Lions Versus Porcupines

What did F99, a subadult female mountain lion followed by Panthera’s Teton Cougar Project, think when she encountered a North American porcupine in early November? A small, female mountain lion in the Northern Rocky Mountains might weigh 80 lbs, while a large porcupine might weigh 20. Certainly, the two species aren’t matched for a fair…

December 7, 2014: Return “Kidnapped” Animals to the Wild, Save the World’s Big Cats and More

This week on National Geographic Weekend, join host Boyd Matson and his guests as they climb El Capitan with young children, stop the kidnapping of Brazil’s wildlife, save lions by saving livestock, lift a 35-ton stone with prehistoric technology, work to save the last 3,000 wild tigers, visit some of the last nomadic tribes, bottle feed a baby cheetah, and clean up hazardous waste.

Mountain Lions Versus Black Bears

F96, nicknamed Frostbite because of the loss of parts of her ears and the tip of her tail during the winter of 2012-13, is a young female mountain lion followed as part of Panthera’s Teton Cougar Project. She dispersed from her mother’s home range in May of this year, when she was 20 months old.…

Fumbling Cougar Kittens: Learning to Hunt

We recently captured F99, a now 1-year old, orphaned, female cougar kitten followed by Panthera’s Teton Cougar Project (see post Why Adult Cougars Kill Each Other? for how she was orphaned and Orphaned Cougar Kittens and Their Inspiring Will to Survive for some of her adventures since). We swapped out the tiny, expandable collar that…
