What’s In A Name?
Cougar, puma, mountain lion, panther, catamount, painter, ghost cat, mountain screamer, red tiger, deer tiger, Mexican lion, American lion. That’s twelve names for the same animal. There are at least 40 more.
No other mammal on earth has this many common names. Not even close. And the reason is simple: Puma concolor has the largest range of any wild land mammal in the Western Hemisphere. From the Yukon to Patagonia, across forests, deserts, swamps, prairies, and mountains, this single species has been encountered and named by people speaking dozens of languages across two continents for thousands of years.
So when someone asks “what’s the difference between a cougar and a puma?” the answer is: nothing. Same animal. Same species. Same DNA. The only difference is who’s talking about it and where.
One Animal, Forty Names
The naming confusion isn’t laziness. It’s geography.
comes from the Quechua language of the Inca, where it meant “powerful animal”. It’s still the standard term across Latin America and in scientific literature globally. The species name is Puma concolor, which translates roughly to “powerful animal of one color”.
has a messier origin. A 16th-century Portuguese naturalist in Brazil recorded an indigenous Tupi name for the jaguar: cuguacu ara. A French naturalist later borrowed it, shortened it to cuguar, and someone along the way started applying it to the wrong cat. The name stuck anyway. It’s the most common term in Canada and parts of the western US.
showed up in English around 1858. It’s the most popular name in the American West, and it’s arguably the least accurate. This cat is not a lion (lions are genus Panthera; pumas are genus Puma) and it doesn’t live exclusively in mountains. It lives everywhere from sea-level swamps to 14,000-foot peaks.
is the most confusing of the bunch. Technically, panther refers to any large cat with a solid-colored coat, and it’s applied to black-phase jaguars and leopards as well as to pumas. The Florida panther (Puma concolor coryi) is the most famous use of this name in North America, and it is very much a puma, not a panther in the Panthera genus sense.
“Catamount” is a contraction of “cat of the mountain”. It was common in the eastern US and New England in the 1600s and 1700s.
“Painter” is an Appalachian dialect corruption of “panther”. Old-timers in the southern mountains still use it.
And the Cree had their own name: Katalgar, meaning “Greatest of Wild Hunters”. The Chickasaw called it Ko-Icto, “Cat of God”.
All the same animal.
So Why Does Anyone Think They’re Different?
Because they look slightly different depending on where they live. A puma in the mountains of British Columbia is bigger, heavier, and has thicker fur than a puma in the Everglades. A Patagonian puma hunting guanacos on the open steppe looks and behaves differently than a Florida panther stalking deer through palmetto scrub.
If you’re not familiar with Bergmann’s Rule, it a simple one: animals living in colder environments are generally larger than their equivalents in warmer climates. Whitetail deer in Central Canada can be much much larger than the whitetail deer found in the Florida keys, for example.
People saw these regional differences and assumed they were looking at different animals. Scientists formalized that assumption into 32 subspecies. For decades, that’s how the taxonomy stood.
Then DNA changed everything.
In the early 2000s, geneticist Stephen O’Brien and his team at the National Cancer Institute collected samples from over 300 pumas across North, Central, and South America. They found that all North American pumas are “virtually indistinguishable” genetically. The 15 supposed North American subspecies collapsed into one. Central America had one. South America had four. The grand total went from 32 subspecies to six.
The most genetically diverse pumas turned up in Paraguay and Brazil south of the Amazon, suggesting those populations are the oldest (around 250,000 years) and that northward migrations gave rise to everything else over time. As of 2017, only two subspecies are formally recognized: Puma concolor couguar (North and Central America) and Puma concolor concolor (South America).
The practical takeaway: the puma I’ve photographed in Torres del Paine, Chile, and the mountain lion a rancher complains about in Montana are more closely related than most people assume. The size and behavioral differences are environmental, not genetic.
Not a Big Cat (Technically)
Here’s a detail that surprises most people: despite weighing up to 220 pounds and being the largest cat in North America, the puma is classified as a “small cat”.
The distinction is anatomical, not about size. Big cats (genus Panthera: lions, tigers, leopards, jaguars, snow leopards) have a flexible hyoid bone in the throat that allows them to roar. Pumas have a rigid hyoid bone. They can’t roar. They purr, hiss, chirp, growl, and produce an eerie high-pitched scream that sounds like a woman crying in the woods. But they cannot roar.
This puts pumas in the same taxonomic subfamily (Felinae) as your house cat, the cheetah, and the ocelot. Their closest living relative is the jaguarundi, a small weasel-shaped cat from Central and South America. Their next closest relative, surprisingly, is the cheetah.
What Makes Pumas Remarkable
Forget the name. What matters about this animal is what it does.
Pumas occupy more habitat types than any other wild cat species. Forest, desert, swamp, grassland, alpine tundra, coastal scrub. From sea level to above treeline. From the boreal forests of British Columbia to the windswept steppe of Patagonia, where I spent four months living and working as a guide out of Futaleufu, Chile. (I never saw a puma the entire time, which is par for the course. These cats are phantoms.)
They consume over 200 documented prey species. Elk, deer, bighorn sheep, guanacos, porcupines, rabbits, mice, raccoons, coyotes, and, as recent research has documented, penguins. At Monte Leon National Park in Argentina, pumas have been recorded hunting Magellanic penguins at the highest population density ever measured for the species anywhere. Researchers recorded 13 pumas per 100 square kilometers, more than double the previous global record. The famously solitary cats were tolerating each other at close range around abundant prey, behaving more like brown bears at a salmon run than like the reclusive solo hunters we think of.
That behavioral flexibility is the real story. Pumas don’t specialize. They adapt. Whatever’s available, wherever they are, they figure it out.
The Florida Panther Problem
The Florida panther is worth its own section because it illustrates both the naming confusion and the conservation stakes.
By the early 1990s, the Florida panther was functionally extinct. Fewer than 25 animals remained in the Everglades and surrounding swampland, and they were in bad shape. Decades of isolation and inbreeding had produced males with heart defects, undescended testicles, and kinked tails. Scientists estimated a 95% chance of extinction within 20 years if nothing changed.
In 1995, wildlife managers brought eight female pumas from Texas to Florida to breed with the surviving males. This was controversial. Critics argued it would “contaminate” the Florida panther subspecies with outside genes.
The genetics told a different story. O’Brien’s team had already shown that all North American pumas were essentially one population. There was no genetically distinct “Florida panther” to contaminate. What there was: a small, inbred group of Puma concolor couguar that desperately needed genetic diversity.
It worked. The population tripled. Health markers improved dramatically. Heart defects declined. The Florida panther exists today because someone decided that the animal mattered more than the name.
But the fix was temporary. Inbreeding markers are creeping back up, habitat continues to shrink, and the cats still get hit by cars on Florida highways at an alarming rate. The panther is not saved. It’s on life support.
Pumas and People
Puma attacks on humans are extremely rare. In a 10-year study in New Mexico, researchers approached wild pumas at a median distance of about 60 feet. The cats displayed threatening behavior in only 6% of encounters, and nearly all of those involved mothers with cubs.
That said, pumas are large predators that occasionally kill people. Most attacks involve juveniles dispersing into new territory and encountering humans for the first time, or adults in areas where development has pushed into their habitat. The standard advice applies: don’t run, don’t crouch, make yourself look large, maintain eye contact, and fight back if attacked.
In Patagonia, the dynamic is different. The pumas of Torres del Paine have been the top predator in their ecosystem for thousands of years. There are no wolves, no bears, no competing large carnivores. As Jim Williams, a Montana Fish, Wildlife & Parks biologist and author of “Path of the Puma”, put it: “Unlike North America, there are no grizzly bears, black bears or wolves, so these cats are not sneaking around in the trees at night like they are up here”. The result is bolder cats that are more visible during daylight hours, which is why Torres del Paine has become one of the best places on earth to photograph wild pumas.
Where to See Pumas
In North America, your best chances are in areas with high deer density and limited hunting pressure. Parts of California, Colorado, Montana, and British Columbia hold solid populations. But “seeing” a puma in North America often means finding tracks, hearing a scream at night, or catching a fleeting glimpse of a tail disappearing into timber. These are cryptic, solitary animals that actively avoid being seen.
In Patagonia, it’s a different world. The cats around Torres del Paine National Park, particularly on the private ranchland bordering the park, are habituated to human presence. With experienced trackers who know individual animals by name, you can photograph wild pumas at relatively close range in open terrain. It’s the closest thing to an African big cat safari that exists in the Americas.
We run a Patagonia Puma Photography Tour out of Torres del Paine: five photographers, five full days with the cats, private ranch access, and trackers who’ve been following these animals for years.
Puma FAQs
Are cougar and puma the same animal? Yes. Cougar, puma, mountain lion, panther, and catamount are all common names for Puma concolor. It’s one species with the widest geographic range of any wild land mammal in the Western Hemisphere. The different names come from different languages and regions across the Americas.
Is a Florida panther a puma? Yes. The Florida panther (Puma concolor coryi) is a regional population of puma, not a true panther in the Panthera genus. The name “panther” was applied historically to any large solid-colored cat. Despite the name, Florida panthers are genetically nearly identical to pumas found across the rest of North America.
Why does one cat have so many names? Because its range spans from Canada to the southern tip of South America. People speaking dozens of languages across two continents encountered the same animal and named it independently. The Inca called it “puma”. Portuguese colonists in Brazil contributed “cougar” (through a convoluted chain of mistranslation). Spanish explorers called it “leon” (lion) and “gato monte” (cat of the mountain). English settlers in Appalachia called it “painter”. The Cree called it “Katalgar”: Greatest of Wild Hunters.
Is a puma a big cat? Technically, no. Despite being the largest cat in North America (up to 220 lbs), pumas are classified in the subfamily Felinae, not Pantherinae. The distinction is anatomical: pumas have a rigid hyoid bone and cannot roar. They purr, chirp, hiss, and scream. True “big cats” (lions, tigers, leopards, jaguars, snow leopards) belong to genus Panthera and can roar. The puma’s closest relative is the jaguarundi, followed by the cheetah.
What’s bigger, a cougar or a puma? They’re the same animal, so neither is bigger. However, pumas do vary significantly in size across their range. Males in northern latitudes (British Columbia, Montana) can reach 200+ pounds. Males in tropical South America may weigh half that. Females are 40-60% smaller than males regardless of location. These size differences are environmental, not genetic.
