Mountain Lion
Puma concolor · Felidae
The ghost of the mountains — North America's largest wild cat.
Found & hunted in
Overview
The mountain lion — also called cougar, puma, or panther depending on region — is the most widely distributed wild cat in the Western Hemisphere and the apex predator of western North American ecosystems. Highly secretive and primarily nocturnal, lions are rarely seen even in areas of high density. The vast majority of mountain lion hunting in the US is done with trained hounds, which track a lion by scent, tree it, and hold it until the hunter arrives to make the shot. Spot-and-stalk lion hunting is possible in areas with good snow tracking conditions.
Habitat
The mountain lion — also called cougar, puma, or panther depending on regional tradition — holds the distinction of having the largest geographic range of any wild terrestrial mammal in the Western Hemisphere, occupying terrain from the Canadian Yukon south through the Rocky Mountain cordillera, the Pacific Ranges, and the Sierra Nevada, and continuing through Central and South America to the tip of Patagonia. Within North America, the species reaches its highest densities in the rugged, broken country of the American West, particularly where the combination of adequate prey, cover, and minimal human disturbance creates ideal habitat conditions.
Mountain lions are obligate ambush predators, and their habitat selection reflects that hunting strategy with precision. They require two fundamental elements: adequate prey density and terrain or vegetation structure that allows close-range approach to prey undetected. The classic lion country that hunters learn to recognize combines rocky outcrops, steep rimrock, and broken terrain — features that allow a stalking cat to approach within 10 to 30 feet of a bedded deer or elk before the prey detects danger — with draws, canyon heads, and dense oakbrush, manzanita, or chaparral that serve as daytime bedding cover.
Elevation range varies enormously by region and season. In the Sierra Nevada and Rocky Mountain ranges, lions follow their deer prey on a seasonal vertical migration, occupying high-elevation summer deer ranges at 7,000 to 10,000 feet during summer and moving to lower foothills and canyon country at 3,000 to 5,000 feet as deer winter herds concentrate in the valleys. In the desert Southwest, lions occupy the broken bajadas, canyon systems, and mountain islands of the Sonoran and Chihuahuan deserts, where isolated ranges separated by desert flats create island biogeography dynamics that influence population structure and connectivity.
The Pacific Coast ranges from northern California through Oregon and Washington support some of the highest verified lion densities in North America, driven by the combination of dense blacktail and Roosevelt elk populations and the impossibly rugged, brushy terrain that provides ideal ambush opportunities. Coastal areas where deer concentrate on winter browse at lower elevations consistently hold lion concentrations, and hunters who invest time learning these winter deer movement patterns discover that they have simultaneously identified the most productive lion hunting areas in their region.
Population
Total mountain lion population estimates for the United States and Canada are notoriously difficult to determine given the animal's secretive habits, enormous home range requirements, and the logistical challenges of counting individual animals over large, rugged landscapes. Current population estimates for the western United States range from 20,000 to 40,000 individuals, with the broadest uncertainty surrounding California's population — estimated at between 4,000 and 6,000 animals — where a 1990 voter initiative banned sport hunting and has created conditions for both population growth and increased human-lion conflict. The mountain lion has recolonized portions of its historical range in the Great Plains and Midwest as the western population has grown and dispersing young males push east, with confirmed breeding populations now documented in Nebraska's Pine Ridge and occasional confirmed individuals as far east as the Mississippi River.
Population density in well-managed hunting states reflects the effectiveness of regulated harvest as a management tool. Colorado, with an estimated population of 3,000 to 7,000 lions and an annual harvest of 300 to 500 animals, maintains stable numbers while managing predator-prey dynamics with mule deer herds that are under pressure from drought and habitat loss. Utah, Idaho, Montana, Wyoming, Nevada, and Arizona all maintain regulated seasons that have kept populations stable or growing. Research conducted using GPS-collar studies has consistently shown that lion populations exhibit compensatory reproduction — when harvest removes animals, reproduction rates increase and juveniles survive at higher rates, maintaining the population within the productive range for the habitat.
The eastern cougar was declared extinct by the U.S. Fish and Wildlife Service in 2011, confirming what wildlife biologists had long suspected — the isolated populations that survived into the twentieth century in the Appalachians and Southeast were extirpated by the early 1900s. The Florida panther, a genetically distinct subspecies, survives with approximately 120 to 230 individuals in the Big Cypress Swamp and surrounding habitats of southwestern Florida, managed intensively under ESA protection and a genetic rescue program that introduced eight Texas pumas in 1995 to address severe inbreeding depression. This population remains critically endangered and is not huntable.
Conservation
Mountain lion conservation in the American West occupies an interesting position compared to most large predators — the species is not federally listed under the Endangered Species Act (with the exception of the Florida panther subspecies), and management authority rests with individual states. This has produced a patchwork of management approaches ranging from California's complete hunting ban to the relatively liberal harvest systems maintained in Idaho and Montana, creating a natural experiment in predator management strategies that wildlife biologists continue to study and debate.
The primary conservation challenges for mountain lions in the western United States are habitat connectivity and human-wildlife conflict. Individual male mountain lions disperse up to 1,000 miles from their natal territory in search of unoccupied range, and their ability to cross major highways, agricultural valleys, and urban areas determines the genetic health of isolated mountain populations. Highway wildlife crossing structures — underpasses and overpasses designed specifically to facilitate safe wildlife passage across divided highways — have been built at critical pinch points in California's I-15 in the Santa Monica Mountains area and are planned for other connectivity bottlenecks, representing a significant conservation investment driven largely by research on mountain lion movement.
Human-wildlife conflict, primarily involving livestock depredation and the occasional safety incident near developed areas, generates significant political pressure on lion management programs. Documented attacks on humans have increased in California in the decades since the hunting ban, though mountain lions remain one of the statistically least dangerous wildlife hazards in the western United States compared to deer-vehicle collisions or even domestic dog bites. Regulated hunting programs, far from threatening lion populations, have been shown by multiple peer-reviewed studies to reduce human-lion conflict by maintaining a population of wary animals with natural fear of humans — a behavioral characteristic that tends to erode in unhunted populations.
Diet
Obligate carnivores — primarily deer (mule deer and whitetail), elk calves, and pronghorn. Also take bighorn sheep, wild pigs, and smaller mammals (coyotes, rabbits, raccoons) opportunistically. A lion kills roughly one deer per week. They cache kills under debris and return to feed for several days.
Social Behavior
Strictly solitary except for mating and a female with dependent kittens. Males hold large territories of 50–150 square miles and actively exclude other males. Females hold smaller, overlapping territories. Lions communicate through scrapes (pawed mounds with urine), claw marks on trees, and scent. They avoid each other in normal circumstances; territory intrusion can lead to lethal fights.
Breeding & Rut
Mountain lions do not have a defined rut season — breeding can occur at any time but peaks in winter. Females are in estrus for about 8 days and may breed multiple times. Kittens (1–4, average 2–3) are born with spotted coats that fade by 6 months. Kittens stay with the female for 1.5–2 years before dispersal.
Scouting
- →Fresh lion tracks in snow or mud are the single most reliable indicator of current activity in your hunting area. Mountain lion front tracks measure 3 to 4.5 inches across and are nearly round, lacking visible claw marks since lions retract their claws while walking — this feature alone distinguishes them from large canine tracks, which show four symmetrical claw marks. Measure the track's metacarpal pad, which has a distinctive three-lobed leading edge, and note the stride length and pattern; a large male in a relaxed walk covers 20 to 30 inches between prints.
- →Learn to recognize lion kill sites, as they reveal far more about the cat's habits and travel patterns than any other sign. Lions kill deer and elk by grabbing the muzzle or back of the skull and rotating the neck to break it, or by suffocating the prey with a sustained throat clamp. The carcass is typically dragged to a secluded location and cached under debris — leaves, sticks, pine needles, or even snow — before the lion retires to a nearby elevated bed to watch and return over subsequent days. A cached kill with fresh material indicates the cat will likely return within 24 hours.
- →Install trail cameras on ridge saddles, canyon bottoms, and creek crossings where lion tracks concentrate, using both infrared and video-capable units positioned at 18 to 24 inches above the ground to capture the full body of a passing cat. Lions are highly neophobic — they will notice and investigate novel objects placed on their travel routes — so allow cameras to settle into the environment for several days before expecting use. Check cameras remotely or minimize visits to preserve scent cleanliness around high-value locations.
- →Study the seasonal deer concentration areas in your hunting unit with the same intensity you would apply to scouting the deer themselves, because mountain lion distribution is a direct function of prey distribution. Winter deer yards — the low-elevation brushy draws, south-facing slopes with shrub browse, and agricultural margins where deer congregate when deep snow drives them out of the high country — are precisely where lions follow, and they are where the most productive lion hound hunting and spot-and-stalk opportunities concentrate from November through February.
- →Identify fresh scratch piles — raised mounds of earth, pine duff, or snow accompanied by strong urine scent — which are the primary territorial marking behavior of adult male lions. These scrapes are often placed at the base of a prominent tree, at the intersection of two game trails, on a ridgeline saddle, or at the edge of a kill site cache. Fresh scrapes with moist soil and strong odor indicate recent activity; scrapes with dry, gray soil or weathered urine scent are days or weeks old. A cluster of active scrapes indicates a resident male's territory center.
- →Glass canyon rims, rocky ledges, and horizontal tree limbs in the early morning and late afternoon — mountain lions bed in elevated positions that provide thermal warmth, shade, and a commanding view of approach routes. A bedded lion at 300 yards looks remarkably like a tawny log or a flat rock until it moves, and even experienced hunters miss them. Use your spotting scope to scrutinize every horizontal feature along cliff faces and ridge lines where the rock turns a warm tan color similar to a lion's coat.
- →In hound hunting for mountain lions — legal in most western states with a regulated hound season — the key scouting task is pre-hunt road work to find the freshest possible track before releasing dogs. Drive accessible road systems on fresh snow mornings before dawn, focusing on creek crossings, saddle roads, and drainage bottoms where cats cross from one canyon system to another. The ideal track is pressed into fresh snow fallen within the last four to six hours, as this maximizes the scent column for the hounds and minimizes the distance the lion has traveled since making the track.
- →Lions travel predictable corridors dictated by terrain, particularly ridge systems that connect prey areas. Identify these natural corridors on topographic maps — the narrow ridge fingers between parallel drainages, the cliff-band traverses above canyon bottoms, the brushy draws that provide a covered route from one meadow system to another — and concentrate your track sign search on these locations. A corridor that produces lion tracks on multiple scouting visits through different seasons is part of a resident lion's regular circuit.
- →Use remote wildlife mortality data strategically: contact your state wildlife agency's research division or regional biologists and ask about documented lion-deer kill locations within your hunting unit. Many agencies collect this data through GPS-collar telemetry studies, and while they will not reveal exact kill locations of collared research animals, they may be able to describe the general habitat types and landscape features where kills concentrate, which directly informs where to focus your scouting effort.
- →Fresh lion scat in a consistent location — particularly scat with evidence of cached kills nearby — indicates a resident animal rather than a transient. Mountain lion scat contains hair, bone fragments, and sometimes hooves of deer and elk, and is typically 1 to 1.5 inches in diameter in adults. Fresh scat has a strong, distinctive odor and moist texture; older scat bleaches gray and loses cohesion. A scat pile containing multiple depositions of different ages indicates a regularly used marking site that belongs to a resident individual, which is far more hunting-relevant than a single, isolated deposit.
- →For spot-and-stalk hunting without hounds — a far more difficult proposition than hound hunting but legal and achievable in open terrain — identify freshly killed lion prey and use your optics to glass the surrounding terrain systematically, paying particular attention to elevated ledge systems within 200 yards of the kill. A lion at a fresh kill will typically not abandon it immediately after being disturbed, and glassing from a position 400 to 600 yards away with the wind in your favor can reveal the cat bedded near its cache within the first hour of daylight.
Gear & Calibers
Hunting Tips
- →Fresh snow is the lion hunter's best friend — tracks are visible and huntable. Most serious lion hunts happen after a fresh snowfall that allows tracking.
- →A good pack of hounds is everything. Lion hunting without dogs is extremely difficult; most successful hunters hire an outfitter with experienced dogs.
- →Look for lion sign near deer concentrations (winter deer yards, canyon bottoms with deer traffic) — lions follow their prey.
- →When a lion is treed, hunters must confirm sex and assess size before shooting. Female lions often have spots or mottled fur; mature toms are larger-bodied.
Stalking Tips
- →True stalk hunting of mountain lions is rare but occurs in canyon country following fresh tracks in snow. Move quietly and methodically; a lion may be bedded nearby.
Glassing Tips
- →Lions are occasionally spotted crossing ridges or rims in early morning in open canyon country. Glass rim edges and talus slopes at first and last light.
Trophy Judging
- →Sex determination is the first and most critical judgment call on a mountain lion, because many states either require harvest of males only, or have specific regulations about females with dependent kittens. Adult male lions are noticeably larger than females — a mature tom averaging 140 to 180 pounds versus a female's 90 to 120 pounds — but size is difficult to judge without a reference point when a cat is alone. The most reliable field indicator is head shape: adult males have a distinctly square, blocky head with a wide, flat forehead, while females have a rounder, smaller head more proportional to a large domestic cat.
- →Scrotal evidence is definitive for sex determination but is rarely visible at practical hunting distances. Behavioral cues help: a female with kittens will exhibit anxiety and frequent looking back and vocalization as she moves ahead of hounds, and kittens will often tree before or separately from the adult female. If hounds are pursuing a group of lions and multiple individuals tree in close proximity, you are almost certainly looking at a female with half-grown kittens, and harvest should be avoided entirely.
- →Body length — measured from tip of nose to tip of tail — is the most common field trophy metric, but assessing it in a treed cat is inherently difficult due to the animal's posture and the typical shooting angle. Experienced hound hunters use the cat's tail length as a proxy for body size, since the tail comprises approximately one-third to two-fifths of total length on a large male. A tail that hangs well below the highest branches when the cat is perched upright, and appears to equal or exceed the length from the cat's chin to its hindquarters, indicates a large individual.
- →Skull size is the accepted B&C and SCI scoring metric for mountain lions, but skull dimensions cannot be accurately evaluated in the field. Use body size as your primary metric — a tom with a shoulder height equal to or exceeding a medium-sized dog and a body length from nose to tail base exceeding 5 feet is almost certainly a prime, mature individual worth taking. Immature males (1 to 3 years old) have not yet reached full body development, appear rangy and long-legged with small heads, and should be passed in areas where regulations permit discretion.
- →Age estimation is imprecise in the field, but coat condition and facial scarring provide useful clues in mature animals. Prime toms aged 4 to 8 years show a clean, lustrous tawny coat with clear facial markings — black-outlined white muzzle patches and distinct black ear tips — and minimal scarring. Old dominant males (8-plus years) often show healed bite scars on the face and legs from territorial fighting, worn canine tips, and a slightly gaunt appearance in the hindquarters even when otherwise healthy.
- →In spot-and-stalk scenarios on open terrain — rare but achievable in the canyon country of the desert Southwest and in open sierra terrain — the classic lion posture of a resting cat is a horizontal elongation on a ledge, with the tail hanging or twitching below the ledge edge. The characteristic facial markings — the black-tipped tail, the black cheek patches, and the distinctly cat-shaped head — are diagnostic at moderate distances. A mountain lion at 200 yards in good light is unmistakable to a careful observer; a partially obscured cat in dense shadow on a cliff face is the source of most misidentification incidents.
- →Trophy quality for a full-body mount is determined as much by coat integrity as by body size. Check the hide carefully for mange (scaly, crusty patches with hair loss), fight wounds that have produced bare patches, and rub marks on the elbows and sternum where older cats develop calloused, thin-haired pressure points. A magnificently large tom with moderate coat damage may produce a less satisfying trophy than a slightly smaller animal in perfect condition, depending on your mount style and aesthetic priorities. Discuss your preferences with your taxidermist before the hunt so you can make informed decisions in the field.
- →If your houndsman advises passing a particular lion for management or population reasons — such as the only known dominant tom in a local area, or a female that may have dependent kittens still in the area — give serious weight to that advice. Experienced hound hunters who know a specific drainage develop detailed knowledge of individual lions from repeated encounters across multiple seasons, and their management instincts generally reflect sound conservation reasoning even when they cannot articulate it in formal wildlife science terms.
Field Care & Dressing
- →Mountain lions are invariably harvested for the trophy — hide, skull, and paws — rather than primarily for meat, though the meat is excellent table fare. The skinning process begins by hanging the cat from the hind legs at a comfortable working height, then making a central belly incision from the base of the tail to the lower jaw, taking care to keep the skin of the face, ears, and paws fully intact. The tail is skinned by splitting along its underside to the tip, keeping the tail bone in the skin for mounting. Many taxidermists prefer an unskinned, whole-frozen lion delivered to their shop, as they can prepare the hide more accurately for mounting if they control the skinning process.
- →If you must skin in the field, invert the hide from the body using careful knife work to separate the thin skin from the underlying muscle, which tends to stick more than deer or elk skin. Work slowly around the face — particularly around the lips, eyelids, and ears — as these are the most difficult areas and the most visible on a finished mount. Turn the ears by working your fingers and knife blade between the ear cartilage and the skin from inside, separating the cartilage from the outer skin completely while leaving cartilage attached to the skin.
- →Mountain lion meat, while not commonly discussed in hunting culture, is genuinely excellent — described by those who have eaten it as tasting similar to pork, with a mild, clean flavor without the gamy character of ungulates. The loins, hindquarters, and backstraps are the primary table cuts. If you intend to keep meat, field dress the carcass immediately after skinning, removing the viscera promptly and cooling the carcass. Since lions are carnivores and scavengers, basic food safety precautions apply — cook lion meat to a minimum internal temperature of 160°F, and be aware that Toxoplasma gondii can be present in carnivore meat.
- →Preserve the skull for your taxidermist or for skull scoring purposes. Skull size — greatest length plus greatest width — determines Boone & Crockett and Pope & Young ranking. A B&C minimum skull for mountain lion is 15 inches total, and record-class cats exceed 16 5/16 inches. Clean the skull minimally in the field, leaving all tissue for the taxidermist if possible, or macerate carefully at home. The teeth, particularly the upper canines that can reach 2 inches in length in large males, are a defining trophy characteristic.
- →In states that require mandatory check-in of harvested mountain lions — which is virtually universal in states with legal lion seasons — you must bring the entire intact carcass or the skull, hide, and paws to a wildlife agency check station within a specified time period after harvest. Regulations typically require the check station to remove a premolar tooth for aging, and in some states, the skull is retained for scoring and data collection. Know your state's specific requirements before you hunt; non-compliance with check-in requirements is a serious wildlife law violation.
- →Protect the hide from blood contamination during field processing, as blood staining on the throat, chest, and legs is difficult to clean and can damage the hair permanently. Use wet cloths or paper towels to remove blood promptly before it sets, and roll the skinned hide flesh-side out for transport. Do not fold the hide on itself hair-side-to-hair-side while it is wet, as this promotes heat buildup and hair slippage. In warm weather, a skinned hide should be refrigerated or frozen within two hours of death.
Things to Know
- →California banned lion hunting in 1990. In all other western states with lion populations, hunting is legal with a license/tag but seasons and bag limits vary widely.
- →Lion hunting requires specialized knowledge. A first-time hunter almost always needs an outfitter with trained hounds.
- →Mountain lions are an important regulator of deer and elk populations. In areas with declining ungulate herds, lion management is a significant wildlife management topic.
