    • Travel many miles at 10 mph
    • Reach speeds of 50 mph in a sprint

Identifying Mountain Lion Tracks

Mountain lions have a distinctive heel pad with 3 lobes visible at the rear of the track (dogs typically only register 2 lobes). Their claw marks usually do not show in the track with some exceptions. When walking, a cougar’s rear paw often steps in the track of the front paw, creating an overlapped pattern. This is called direct register. Cougars will also walk with the rear track registering in front of the front track. This is called an overstep walk. Both of these gaits can occur at greater speed indicating a trot, which will increase the stride length. Their paws have a leading toe, similar to how a human hand has a leading finger. This indicates right or left paw. Dog tracks are more symmetrical with no leading toe and the negative space between their toes and heel pad creates an ‘X’ shape.

Are Mountain Lions, Cougars and Panthers all the Same Animal?

YES! The American lion’s scientific name is Puma concolor, and is sometimes referred to as “the cat of many names.” The scientific name was changed from “Felis concolor” in recent decades. Mountain lions once ranged more extensively than any other mammal in the Western Hemisphere. Historically they could be found anywhere from the Canadian Yukon to the Straits of Magellan — over 110 degrees in latitude — and from the Atlantic seaboard to the Pacific Ocean. As a result, each native tribe and group of European explorers gave the cat a different name. Today, mountain lions are listed in dictionaries under more names than any other animal in the world. Writer Claude T. Barnes listed 18 native South American, 25 native North American, and 40 English names for the same animal. Depending on the region and native language, common names for the American lion include: mountain lion, cougar, panther, puma, painter, el leon, and catamount. 

Although the mountain lion may have more names and nicknames than any other animal, the following are not names for lions and represent completely different species: bobcat, lynx, ocelot, jaguar, leopard, cheetah, Asiatic lion, African lion, and tiger. Many people have heard the term “black panther,” but these are actually melanistic jaguars or leopards: a genetic trait that makes an individual cat’s fur appear much darker than the usual coloration. To date there has never been a confirmed case of a melanistic (black) mountain lion.

How Many Mountain Lions Are There?

No one knows exactly how many mountain lions live in North America. Unlike herd animals, mountain lions are solitary, wide-ranging, and naturally occur at low densities across vast landscapes. They are also highly elusive, making them one of the most difficult large mammals to study and count.
 
Rather than conducting direct counts, wildlife agencies estimate mountain lion populations using a combination of GPS collar studies, camera traps, genetics, habitat models, harvest data, and long-term research. These methods provide useful estimates, but they are not precise, and approaches vary among states and provinces.
 
Published estimates suggest there are tens of thousands of mountain lions across the western United States. More important than a continental total, however, is the health of individual populations. Some are stable and well connected, while others face challenges from habitat fragmentation, barriers to movement, or management practices that may not be sustainable over the long term.
 
At the Mountain Lion Foundation, our focus is not on arriving at a single population number. It is on ensuring mountain lions are managed using the best available science so healthy populations continue to thrive as part of resilient ecosystems.

What Do Mountain Lions Look Like?

Puma concolor means lion of one color. Adult mountain lions have a tan-colored coat — much like the African lion — but are slighter in build with a head that is smaller in proportion to its body.

The sexes look alike, though male lions are 30 to 40 percent larger than females. Though sizes vary greatly throughout the cat’s geographic range, a typical adult male will weigh 110 to 180 pounds and the female 80 to 130 pounds. Exceptional individuals have exceeded 200 pounds, but this is rare. Adult males will measure 6 to 8 feet from nose to tail tip and females 5 to 7 feet. The most recognizable feature of the American lion is its long and heavy tail, which measures almost one-third of the lion’s total length.

Mountain lion kittens or cubs (either term is correct) have camouflaging spots and rings around their tails that fade as they mature. These spots fade to faint dapples by about 9 months of age and at around a year old, young cougars look nearly identical to an adult. This can create confusion because it may look like multiple individuals are traveling in together. If you see more than one cougar together this is usually a family group. This family will break up when the young are, on average, 15 months old.

Where do mountain lions live in the U.S.?

Mountain lions are the most widely distributed wild cat in the Americas and once ranged across nearly every habitat in the United States. Today, established breeding populations remain primarily in the western United States, with the endangered Florida panther persisting in the Southeast. Young mountain lions occasionally disperse hundreds or even thousands of miles beyond these populations, highlighting the species’ remarkable ability to explore and recolonize suitable habitat.
 
Mountain lions are highly adaptable. They live in deserts, forests, mountains, grasslands, shrublands, and coastal ecosystems—wherever they can find adequate prey, cover, and space. Their continued success depends not only on habitat quality but also on connected landscapes that allow animals to move safely between populations.
 
Although generally solitary, mountain lions are more socially flexible than once believed. Individuals communicate through scent marking, maintain overlapping home ranges in some areas, and may tolerate one another at shared food sources. Females raise kittens alone, moving them among several den sites during their first months of life.
 
Because mountain lions require large, connected landscapes, they are often considered an indicator of ecosystem health. Conserving habitat for mountain lions benefits countless other wildlife species and helps maintain the ecological processes that healthy landscapes depend upon.

What Do Mountain Lions Eat?

Mountain lions are ambush predators that rely on stealth, patience, and powerful bursts of speed to capture prey. They hunt primarily deer, but their diet varies depending on where they live and what is available. Across their range, they also prey on elk, bighorn sheep, feral hogs, smaller mammals, and occasionally other wildlife.
 
After making a kill, mountain lions often drag their prey to a secluded location and cover it with leaves, grass, snow, or other natural materials. They typically return over several days to feed, providing an important food source for bears, birds, and many other scavengers.
 
As native apex predators, mountain lions play an important role in healthy ecosystems. By naturally influencing prey populations and behavior, they help maintain ecological processes that benefit many other species. This is the Lion Effect.

Are Mountain Lions Dangerous?

To deer, yes! To people, not so much. Human encounters with mountain lions are rare and the risk of an attack is infinitely small. You are more likely to drown in your bathtub, be killed by a pet dog, or hit by lightning. If lions had any natural urge to hunt people, there would be attacks every single day. Instead, they avoid us.

But if you live, work, or play in cat country, be alert! Avoid walking alone between dusk and dawn when lions are most active. Keep your children and pets close to you. Never approach or corner a mountain lion (or any wild animal). If you do encounter a mountain lion, STOP. DO NOT RUN. Unlike safety advice for encountering bears, do not act timid or play dead in front of a cat.

Instead: Maintain eye contact. Stand tall. Look bigger by opening your coat or raising your arms. Slowly wave your arms and speak firmly. Back away slowly but be careful not to trip or fall over. Most encounters where a cougar approaches a human are because the cougar wants to move the person away from kittens or a food resource. Backing away slowly will provide space, and the cougar will move on once there is enough space. Some very rare encounters are aggressive. Throw items at the lion if necessary. Give the cat room and time to move on. Remain aware and cautious. Bear spray is effective on cougars. It may take more than one spray, so don’t empty the can on the first deployment. Be sure to educate yourself on the correct way to use bear spray. 

In the rare event of an attack, fight back. Most people succeed in driving the mountain lion away.

How Can I Protect My Pets and Livestock from Mountain Lions?

Living and working in mountain lion country sometimes means sharing the landscape with large carnivores. While conflicts with pets and livestock can occur, decades of research and practical experience have shown that many can be reduced through thoughtful, proactive measures tailored to the situation.
 
The most effective approaches combine good animal husbandry with proven deterrents. Bringing pets indoors at night, using secure nighttime enclosures for vulnerable livestock, employing livestock guardian dogs where appropriate, and using fencing, lighting, or other deterrent devices can all help reduce the likelihood of predation.
 
There is no single solution that works everywhere. The best approach depends on the landscape, the animals involved, and the unique challenges each property faces. Successful coexistence is built on understanding local conditions, applying proven techniques, and adapting them over time.

If Mountain Lions Aren’t Endangered Why Do They Need to Be Protected?

Mountain lions are not listed as endangered across most of North America, but that doesn’t mean they no longer need thoughtful conservation. Like many wide-ranging species, their long-term health depends on how they are managed and whether they can continue to move safely across connected landscapes.
 
Mountain lions occur naturally at low densities and reproduce slowly. Their populations can remain healthy when management is guided by sound science, but they can also decline where habitat is fragmented, connectivity is lost, or hunting and conflict-related killings become unsustainable. Because management decisions vary widely across states and provinces, the outlook for mountain lions is not the same everywhere.
 
Mountain lions are also an important part of healthy ecosystems. As apex predators, they influence prey populations and behavior, creating ecological effects that ripple throughout the landscape. Healthy predator populations contribute to more resilient ecosystems, richer biodiversity, and functioning natural processes.
 
The Mountain Lion Foundation works to ensure mountain lions continue to thrive wherever they occur. That means advocating for science-based wildlife management, protecting habitat and wildlife corridors, supporting research, promoting coexistence, and helping ensure that decisions about mountain lions are guided by the best available science and the public trust.

Will Mountain Lions Ever Return to the Eastern United States?

Mountain lions once occupied nearly every major habitat across the Americas, from the Atlantic forests to the Pacific coast, from deserts and mountains to wetlands and temperate forests. Their disappearance from the eastern United States was not the result of ecological limitations, but of widespread persecution and landscape change.
 
Today, much of that landscape has changed again. Forests have returned across large portions of the East, deer populations are abundant, and many wildlife species once thought lost, including black bears, elk, wolves in some regions, and even mountain lions as occasional dispersers, are demonstrating nature’s remarkable capacity for recovery.
 
Whether mountain lions establish breeding populations in the East will depend on more than habitat alone. It will require connected landscapes, thoughtful wildlife management, and, perhaps most importantly, public acceptance. In some places, natural recolonization may be possible. In others, restoring mountain lions could require more active conservation approaches. Those decisions should always be guided by sound science, careful planning, and meaningful public engagement.
 
At the Mountain Lion Foundation, we believe the larger goal is not simply returning mountain lions to places where they once lived. It is restoring healthy, connected ecosystems where wildlife, and people, can thrive together. How mountain lions return, where they return, and whether they return should be informed by the best available science and the communities who will share the landscape with them.

What is the Mountain Lion Foundation?

The Mountain Lion Foundation is the nation’s leading nonprofit dedicated exclusively to the conservation of mountain lions. Through science, education, advocacy, and practical coexistence solutions, we work to protect mountain lions and the healthy, connected landscapes they help shape.
