"Mountain lion" redirects here. For other uses, see Cougar (disambiguation) and Mountain lion (disambiguation).

The cougar (Puma concolor) (/ˈkuːɡər/, KOO-gər), also known as the puma, mountain lion, catamount or panther, is a large cat native to the Americas, second only in size to the stockier jaguar. They are not technically grouped with the "true" big cats, as they are slightly smaller than other big cats, and they lack the vocal physiology to roar (unlike lions, tigers, leopards and jaguars). Its range spans from the Canadian Provinces of the Yukon, British Columbia and Alberta, the Rocky Mountains and areas to the Western United States. Their range extends further south through Mexico, where they are found in nearly every state, to the Amazon Rainforest and the southern Andes Mountains in Patagonia. The puma (as it is called in Spanish) inhabits every mainland country in Central and South America, making it the most widely distributed large, wild, terrestrial mammal in the Western Hemisphere, and one of the most widespread on planet Earth. It is an adaptable, generalist species, occurring in most American habitat types. It prefers habitats with dense underbrush and rocky areas for stalking but also lives in open areas.

Cougar range (without recent confirmations across northern Canadian territories, eastern U.S. states, and Alaska)

The cougar is largely solitary by nature and considered both nocturnal and crepuscular, although daytime sightings do occur. It is an ambush predator that pursues a wide variety of prey. Primary food sources are ungulates, particularly deer, but it also hunts smaller prey, such as rodents. Cougars are territorial and live at low population densities. Individual home ranges depend on terrain, vegetation and abundance of prey. While large, it is not always the apex predator in its range, yielding prey it has killed to American black bears, grizzly bears and wolf packs. It is reclusive and mostly avoids people. Fatal attacks on humans are rare but increased in North America as more people entered cougar habitat and built farms.

Intensive hunting following European colonization of the Americas and ongoing human development into cougar habitat has caused populations to decline in most parts of its historical range. In particular, the eastern cougar population is considered to be mostly locally extinct in eastern North America since the early 20th century, with the exception of the isolated Florida panther subpopulation.

Naming and etymology

 
Look up cougar in Wiktionary, the free dictionary.

The word cougar is borrowed from the Portuguese çuçuarana, via French; it was originally derived from the Tupi language. A current form in Brazil is suçuarana.[3] In the 17th century, Georg Marcgrave named it cuguacu ara. Marcgrave's rendering was reproduced in 1648 by his associate Willem Piso. Cuguacu ara was then adopted by John Ray in 1693.[4] In 1774, Georges-Louis Leclerc, Comte de Buffon converted cuguacu ara to cuguar, which was later modified to "cougar" in English.[5][6]

The cougar holds the Guinness record for the animal with the greatest number of names, with over 40 in English alone.[7] "Puma" is the common name used in Latin America and most parts of Europe. The term puma is also sometimes used in the United States.[8][9][10][11] The first use of puma in English dates to 1777, introduced from Spanish from the Quechua language.[12] In the western United States and Canada, it is also called "mountain lion", a name first used in writing in 1858.[13] Other names include "panther" (although it does not belong to the genus Panthera) and "catamount" (meaning "cat of the mountains").[14]

Taxonomy and evolution

Felis concolor was the scientific name proposed by Carl Linnaeus in 1771 for a cat with a long tail from Brazil.[15] The second half of the name, "concolor" is Latin for "of uniform color". It was placed in the genus Puma by William Jardine in 1834.[16] This genus is part of the Felinae.[2] The cougar is most closely related to the jaguarundi and the cheetah.[17][18]

Subspecies

Following Linnaeus's first scientific description of the cougar, 32 cougar zoological specimens were described and proposed as subspecies until the late 1980s. Genetic analysis of cougar mitochondrial DNA indicate that many of these are too similar to be recognized as distinct at a molecular level, but that only six phylogeographic groups exist. The Florida panther samples showed a low microsatellite variation, possibly due to inbreeding.[18] Following this research, the authors of Mammal Species of the World recognized the following six subspecies in 2005:[2]

  • P. c. concolor (Linnaeus, 1771) includes the synonyms bangsi, incarum, osgoodi, soasoaranna, sussuarana, soderstromii, suçuaçuara, and wavula
  • P. c. puma (Molina, 1782) includes the synonyms araucanus, concolor, patagonica, pearsoni, and puma (Trouessart, 1904)
  • P. c. couguar (Kerr, 1792) includes arundivaga, aztecus, browni, californica, floridana, hippolestes, improcera, kaibabensis, mayensis, missoulensis, olympus, oregonensis, schorgeri, stanleyana, vancouverensis, and youngi
  • P. c. costaricensis (Merriam, 1901)
  • P. c. anthonyi (Nelson and Goldman, 1931) includes acrocodia, borbensis, capricornensis, concolor, greeni, and nigra
  • P. c. cabrerae Pocock, 1940 includes hudsonii and puma proposed by Marcelli in 1922

In 2006, the Florida panther was still referred to as a distinct subspecies P. c. coryi in research works.[19]

As of 2017, the Cat Classification Taskforce of the Cat Specialist Group recognizes only two subspecies as valid:[20]

  • P. c. concolor in South America, possibly excluding the region northwest of the Andes
  • P. c. couguar in North and Central America and possibly northwestern South America

The Puma lineage of the family Felidae, depicted along with closely related genera[21]

The family Felidae is believed to have originated in Asia about 11 million years ago (Mya). Taxonomic research on felids remains partial, and much of what is known about their evolutionary history is based on mitochondrial DNA analysis.[17] Significant confidence intervals exist with suggested dates. In the latest genomic study of the Felidae, the common ancestor of today's Leopardus, Lynx, Puma, Prionailurus, and Felis lineages migrated across the Bering land bridge into the Americas 8.0 to 8.5 million years ago. The lineages subsequently diverged in that order.[17] North American felids then invaded South America 2–4 Mya as part of the Great American Interchange, following the formation of the Isthmus of Panama.[18]

The cheetah lineage is suggested by some studies to have diverged from the Puma lineage in the Americas and migrated back to Asia and Africa,[17][18] while other research suggests the cheetah diverged in the Old World itself.[22] A high level of genetic similarity has been found among North American cougar populations, suggesting they are all fairly recent descendants of a small ancestral group. Culver et al. propose the original North American cougar population was extirpated during the Pleistocene extinctions some 10,000 years ago, when other large mammals, such as Smilodon, also disappeared. North America was then repopulated by South American cougars.[18]

A coprolite identified as from a cougar was excavated in Argentina's Catamarca Province and dated to 17,002–16,573 years old. It contained Toxascaris leonina eggs. This finding indicates that the cougar and the parasite existed in South America since at least the Late Pleistocene.[23]

Characteristics

The head of the cougar is round, and the ears are erect. Its powerful forequarters, neck, and jaw serve to grasp and hold large prey. It has four retractile claws on its hind paws and five on its forepaws, of which one is a dewclaw. The larger front feet and claws are adaptations for clutching prey.[24]

Cougars are slender and agile members of the Felidae. They are the fourth largest cat species worldwide;[25] adults stand about 60 to 90 cm (24 to 35 in) tall at the shoulders.[26] Adult males are around 2.4 m (7 ft 10 in) long from nose to tail tip, and females average 2.05 m (6 ft 9 in), with overall ranges between 1.50 to 2.75 m (4 ft 11 in to 9 ft 0 in) nose to tail suggested for the species in general.[27][28] Of this length, the tail typically accounts for 63 to 95 cm (25 to 37 in).[29] Males generally weigh 53 to 72 kg (117 to 159 lb). Females typically weigh between 34 and 48 kg (75 and 106 lb).[29][30] Cougar size is smallest close to the equator and larger towards the poles.[31] The largest recorded cougar, shot in 1901, weighed 105.2 kg (232 lb); claims of 125.2 kg (276 lb) and 118 kg (260 lb) have been reported, though they were probably exaggerated.[32] On average, adult male cougars in British Columbia weigh 56.7 kg (125 lb) and adult females 45.4 kg (100 lb), though several male cougars in British Columbia weighed between 86.4 and 95.5 kg (190 and 211 lb).[33]

Depending on the locality, cougars can be smaller or bigger than jaguars but are less muscular and not as powerfully built, so on average their weight is less. Whereas the size of cougars tends to increase as distance from the equator increases,[31] which crosses the northern portion of South America, jaguars are generally smaller north of the Amazon River in South America and larger south of it. For example, while South American jaguars are comparatively large, and may exceed 90 kg (200 lb),[34] North American jaguars in Mexico's Chamela-Cuixmala Biosphere Reserve weigh approximately 50 kg (110 lb), about the same as female cougars.[35]

Cougar coloring is plain (hence the Latin concolor ["one color"] in the scientific name) but can vary greatly across individuals, and even siblings. The coat is typically tawny, but it otherwise ranges from silvery-grey to reddish with lighter patches on the underbody, including the jaws, chin, and throat. Infants are spotted and born with blue eyes and rings on their tails;[30] juveniles are pale, and dark spots remain on their flanks.[28] A leucistic individual was seen in Serra dos Órgãos National Park in Rio de Janeiro in 2013 when it was recorded by a camera trap, indicating that pure white individuals do exist within the species, though they are extremely rare.[36][37]

The cougar has large paws and proportionally the largest hind legs in the Felidae,[30] allowing for its great leaping and short-sprint ability. It is capable of leaping from the ground up to 5.5 m (18 ft) high into a tree.[38]

Distribution and habitat

The cougar has the largest range of any wild land animal in the Americas, spanning 110 degrees of latitude from the Yukon Territory in Canada to the southern Andes in Chile.[1] The species was extirpated from eastern North America, aside from Florida, but they may be recolonizing their former range and isolated populations have been documented east of their contemporary ranges in both the Midwestern US and Canada.[39]

The cougar lives in all forest types, lowland and mountainous deserts and in open areas with little vegetation up to an elevation of 5,800 m (19,000 ft).[1] In the Santa Ana Mountains, it prefers steep canyons, escarpments, rim rocks and dense brush.[40] In Mexico, it was recorded in the Sierra de San Carlos.[41] In the Yucatán Peninsula, it inhabits secondary and semi-deciduous forests in El Eden Ecological Reserve.[42] In El Salvador, it was recorded in lower montane forest in Montecristo National Park and in a river basin in the Morazán Department above 700 m (2,300 ft) in 2019.[43] In Colombia, it was recorded in a palm oil plantation close to a riparian forest in the Llanos Basin, and close to water bodies in the Magdalena River Valley.[44][45] In the human-modified landscape of central Argentina, it inhabits bushland with abundant vegetation cover and prey species.[46]

Behavior and ecology

Cougars are important keystone species in Western Hemisphere ecosystems, linking numerous different species at many trophic levels. In a comprehensive literature review of more than 160 studies on cougar ecology, ecological interactions with 485 other species in cougar-inhabited ecosystems have been shown to involve different areas of interaction, ranging from the use of other species as food sources and prey, fear effects on potential prey, effects from carcass remains left behind, to competitive effects on other predator species in shared habitat. The most common research topic in the literature used here was the diet of the cougar and the regulation of its prey.[47]

Hunting and diet

 
Cougar with deer kill

The cougar is a generalist hypercarnivore. It prefers large mammals such as mule deer, white-tailed deer, elk, moose, mountain goat and bighorn sheep. It opportunistically takes smaller prey such as rodents, lagomorphs, smaller carnivores, birds and even domestic animals including pets.[48] The mean weight of cougar vertebrate prey increases with its body weight and is lower in areas closer to the equator. A survey of North America research found 68% of prey items were ungulates, especially deer. Only the Florida panther showed variation, often preferring feral hogs and armadillos.[31] Cougars have been known to prey on introduced gemsbok populations in New Mexico.[49] Elsewhere in the southwestern United States, they have been recorded to also prey on feral horses in the Great Basin,[50] as well as feral donkeys in the Sonoran and Mojave Deserts.[51]

Investigations at Yellowstone National Park showed that elk and mule deer were the cougar's primary targets; the prey base is shared with the park's wolves, with which the cougar competes for resources.[52] A study on winter kills from November to April in Alberta showed that ungulates accounted for greater than 99% of the cougar diet. Learned, individual prey recognition was observed, as some cougars rarely killed bighorn sheep, while others relied heavily on the species.[53]

In the Central and South American cougar range, the ratio of deer in the diet declines. Small to mid-sized mammals are preferred, including large rodents such as the capybara. Ungulates accounted for only 35% of prey items in one survey, about half that of North America. Competition with the larger jaguar in South America has been suggested for the decline in the size of prey items.[31] In Central or North America, the cougar and jaguar share the same prey, depending on its abundance.[54] Other listed prey species of the cougar include mice, porcupines, American beavers, raccoons, hares, guanacoes, peccaries, vicuñas, rheas and wild turkeys.[55] Birds and small reptiles are sometimes preyed upon in the south, but this is rarely recorded in North America.[31] Magellanic penguins (Spheniscus magellanicus) constitute the majority of prey items in cougar diet in Patagonia's Bosques Petrificados de Jaramillo National Park and Monte León National Park.[56]

Although capable of sprinting, the cougar is typically an ambush predator. It stalks through brush and trees, across ledges, or other covered spots, before delivering a powerful leap onto the back of its prey and a suffocating neck bite. The cougar is capable of breaking the neck of some of its smaller prey with a strong bite and momentum bearing the animal to the ground.[24] Kills are generally estimated around one large ungulate every two weeks. The period shrinks for females raising young, and may be as short as one kill every three days when cubs are nearly mature around 15 months.[30] The cat drags a kill to a preferred spot, covers it with brush, and returns to feed over a period of days. The cougar is generally reported to not be a scavenger, but deer carcasses left exposed for study were scavenged by cougars in California, suggesting more opportunistic behavior.[57]

Interactions with other predators

Aside from humans, no species preys upon mature cougars in the wild, although conflicts with other predators or scavengers occur. Of the large predators in Yellowstone National Park – the grizzly bear, the black bear, the gray wolf, and the cougar – the massive grizzly bear appears dominant, often (but not always) able to drive a gray wolf pack, an American black bear, and a cougar off their kills. One study found that grizzlies and American black bears visited 24% of cougar kills in Yellowstone and Glacier National Parks, usurping 10% of carcasses. Bears gained up to 113% and cougars lost up to 26% of their respective daily energy requirements from these encounters.[58] In Colorado and California, American black bears were found to visit 48% and 77% of kills, respectively. In general, cougars are subordinate to American black bears when it comes to kills and when bears are most active, the cats take prey more frequently and spend less time feeding on each kill. Unlike several subordinate predators from other ecosystems, cougars do not appear to take advantage of spatial or temporal refuges to avoid their competitors.[59][60]

The gray wolf and the cougar compete more directly for prey, mostly in winter. Packs of wolves can steal cougars' kills, and there are some documented cases of cougars being killed by them. One report describes a large pack of seven to 11 wolves killing a female cougar and her kittens,[61] while in nearby Sun Valley, Idaho, a 2-year-old male cougar was found dead, apparently killed by a wolf pack.[62] Conversely, one-to-one confrontations tend to be dominated by the cat, and there are various documented accounts where wolves have been ambushed and killed,[63][64][65][66] including adult male specimens.[67] Wolves more broadly affect cougar population dynamics and distribution by dominating territory and prey opportunities, and disrupting the feline's behavior. Preliminary research in Yellowstone, for instance, has shown displacement of the cougar by wolves.[68] One researcher in Oregon noted: "When there is a pack around, cougars are not comfortable around their kills or raising kittens [...] A lot of times a big cougar will kill a wolf, but the pack phenomenon changes the table."[69] Both species are capable of killing mid-sized predators, such as bobcats, Canada lynxes, wolverines and coyotes, and tend to suppress their numbers.[52] Although cougars can kill coyotes, the latter have been documented attempting to prey on cougar cubs.[70]

In the southern portion of its range, the cougar and jaguar share overlapping territory.[71] The jaguar tends to take the larger prey where ranges overlap, reducing both the cougar's potential size and the likelihood of direct competition between the two cats.[31] Cougars appear better than jaguars at exploiting a broader prey niche and smaller prey.[72]

Social spacing and interactions

Like almost all cats, the cougar is a mostly solitary animal. Only mothers and kittens live in groups, with adults meeting rarely. While generally loners, cougars will reciprocally share kills with one another and seem to organize themselves into small communities defined by the territories of dominant males. Cats within these areas socialize more frequently with each other than with outsiders.[73]

Home range sizes and overall cougar abundance depend on terrain, vegetation, and prey abundance.[74] Research suggests a lower limit of 25 km2 (9.7 sq mi) and upper limit of 1,300 km2 (500 sq mi) of home range for males.[75] Large male home ranges of 150 to 1,000 km2 (58 to 386 sq mi) with female ranges half that size.[76] One female adjacent to the San Andres Mountains was found with a large range of 215 km2 (83 sq mi), necessitated by poor prey abundance.[77] Research has shown cougar abundances from 0.5 animals to as many as seven per 100 km2 (39 sq mi).[78]

Male home ranges include or overlap with those of females but, at least where studied, not with those of other males. Home ranges of females overlap slightly. Males create scrapes composed of leaves and duff with their hind feet, and mark them with urine and sometimes feces.[79] When males encounter each other, they vocalize and may engage in violent conflict if neither backs down.[80]

Cougars communicate with various vocalizations. Aggressive sounds include growls, spits, snarls and hisses. During the mating season, estrus females produce caterwauls or yowls to attract mates and males respond with similar vocals. Mothers and offspring keep in contact with whistles, chirps and mews.[48][81]

Reproduction and life cycle

Cubs

Females reach sexual maturity at the age of 18 months to three years and are in estrus for about eight days of a 23-day cycle; the gestation period is approximately 91 days.[30] Both adult males and females may mate with multiple partners and a female's litter can have multiple paternities.[48] Copulation is brief but frequent. Chronic stress can result in low reproductive rates in captivity as well as in the field.[82]

Gestation is 82–103 days long.[48] Only females are involved in parenting. Litter size is between one and six cubs; typically two. Caves and other alcoves that offer protection are used as litter dens. Born blind, cubs are completely dependent on their mother at first, and begin to be weaned at around three months of age. As they grow, they begin to go out on forays with their mother, first visiting kill sites, and after six months beginning to hunt small prey on their own.[75][48] Kitten survival rates are just over one per litter.[30]

Juveniles remain with their mothers for one to two years.[48] When the females reaches estrous again, their offspring must disperse or the male will kill them. Males tend to disperse further than females.[83] One study has shown a high mortality rate amongst cougars that travel farthest from their maternal range, often due to conflicts with other cougars.[75] In a study area in New Mexico, males dispersed farther than females, traversed large expanses of non-cougar habitat and were probably most responsible for nuclear gene flow between habitat patches.[84]

Life expectancy in the wild is reported at 8 to 13 years, and probably averages 8 to 10; a female of at least 18 years was reported killed by hunters on Vancouver Island.[30] Cougars may live as long as 20 years in captivity. Causes of death in the wild include disability and disease, competition with other cougars, starvation, accidents, and, where allowed, hunting. The feline immunodeficiency virus is well-adapted to the cougar.[85]

Conservation

The cougar has been listed as Least Concern on the IUCN Red List since 2008. However, it is also listed on CITES Appendix II.[1] Hunting it is prohibited in California, Costa Rica, Honduras, Nicaragua, Guatemala, Panama, Venezuela, Colombia, French Guiana, Suriname, Bolivia, Brazil, Chile, Paraguay, Uruguay and most of Argentina. Hunting is regulated in Canada, Mexico, Peru and the United States.[30] Establishing wildlife corridors and protecting sufficient range areas are critical for the sustainability of cougar populations. Research simulations showed that it faces a low extinction risk in areas larger than 2,200 km2 (850 sq mi). Between one and four new individuals entering a population per decade markedly increases persistence, thus highlighting the importance of habitat corridors.[86]

The Florida panther population is afforded protection under the Endangered Species Act.[87][88] The Texas Mountain Lion Conservation Project was launched in 2009 and aimed at raising awareness of local people about the status and ecological role of the cougar, and mitigating conflict between landowners and cougars.[89]

The cougar is threatened by habitat loss, habitat fragmentation, and depletion of its prey base due to poaching. Hunting is legal in western United States. In Florida heavy traffic causes frequent accidents involving cougars. Highways are a major barrier for dispersal of cougars.[1] The cougar populations in California are becoming fragmented with the increase of human population and infrastructure growth in the state.[90]

Human–wildlife conflict in proximity of 5 km2 (1.9 sq mi) of cougar habitat is pronounced in areas with a median human density of 32.48 inhabitants/km2 (84.1 inhabitants/sq mi) and a median livestock population density of 5.3 heads/km2 (14 heads/sq mi). Conflict is generally lower in areas more than 16.1 km (10.0 mi) away from roads and 27.8 km (17.3 mi) away from settlements.[91]

Relationships with humans

Attacks on humans

In North America

See also: List of fatal cougar attacks in North America
 
Mountain lion warning sign in California, U.S.

Due to the expanding human population, cougar ranges increasingly overlap with areas inhabited by humans. Attacks on humans are very rare, as cougar prey recognition is a learned behavior and they do not generally recognize humans as prey.[92] In a 10-year study in New Mexico of wild cougars who were not habituated to humans, the animals did not exhibit threatening behavior to researchers who approached closely (median distance=18.5 m; 61 feet) except in 6% of cases; 14/16 of those were females with cubs.[93] Attacks on people, livestock, and pets may occur when a puma habituates to humans or is in a condition of severe starvation. Attacks are most frequent during late spring and summer, when juvenile cougars leave their mothers and search for new territory.[94]

Between 1890 and 1990 in North America there were 53 reported, confirmed attacks on humans, resulting in 48 nonfatal injuries and 10 deaths of humans (the total is greater than 53 because some attacks had more than one victim).[95] By 2004, the count had climbed to 88 attacks and 20 deaths.[96]

Within North America, the distribution of attacks is not uniform. The heavily populated state of California saw a dozen attacks 1986 to 2004 (after just three from 1890 to 1985), including three fatalities.[97] Washington state was the site of a fatal attack in 2018, its first since 1924.[98] Lightly populated New Mexico reported an attack in 2008, the first there since 1974.[99]

As with many predators, a cougar may attack if cornered, if a fleeing human stimulates their instinct to chase, or if a person "plays dead". Standing still may cause the cougar to consider a person easy prey.[100] Exaggerating the threat to the animal through intense eye contact, loud shouting, and any other action to appear larger and more menacing, may make the animal retreat. Fighting back with sticks and rocks, or even bare hands, is often effective in persuading an attacking cougar to disengage.[92][94]

When cougars do attack, they usually employ their characteristic neck bite, attempting to position their teeth between the vertebrae and into the spinal cord. Neck, head, and spinal injuries are common and sometimes fatal.[92] Children are at greatest risk of attack, and least likely to survive an encounter. Detailed research into attacks prior to 1991 showed that 64% of all victims – and almost all fatalities – were children. The same study showed the highest proportion of attacks to have occurred in British Columbia, particularly on Vancouver Island where cougar populations are especially dense.[95] Preceding attacks on humans, cougars display aberrant behavior, such as activity during daylight hours, a lack of fear of humans, and stalking humans. There have sometimes been incidents of pet cougars mauling people.[101][102]

Research on new wildlife collars may be able to reduce human-animal conflicts by predicting when and where predatory animals hunt. This may save the lives of humans, pets, and livestock as well as the lives of these large predatory mammals that are important to the balance of ecosystems.[103]

In South America

Pumas in the southern cone of America – often called Argentine cougars by North Americans – are reputed to be extremely reluctant to attack man; in legend, they defended people against jaguars.[104] The nineteenth century naturalists Félix de Azara[105] and William Henry Hudson[106] thought that attacks on people, even children or sleeping adults, did not happen. Hudson, citing anecdotal evidence from hunters, claimed that pumas were positively inhibited from attacking people, even in self-defense. In fact, attacks on humans, although exceedingly rare, have occurred.[107][108]

An early, authenticated, non-fatal case occurred near Lake Viedma, Patagonia in 1877 when a female mauled the Argentine scientist Francisco P. Moreno; Moreno afterwards showed the scars to Theodore Roosevelt. In this instance, however, Moreno had been wearing a guanaco-hide poncho round his neck and head as protection against the cold;[109] in Patagonia the guanaco is the puma's chief prey animal.[110] Another authenticated case occurred in 1997 in Iguazú National Park in northeastern Argentina, when the 20-month-old son of a ranger was killed by a female puma. Forensic analysis found specimens of the child's hair and clothing fibers in the animal's stomach. In this area the coatí is the puma's chief prey. Despite prohibitory signs, coatis are hand-fed by tourists in the park, causing unnatural approximation between cougars and humans. This particular puma had been raised in captivity and released into the wild.[111] On March 13, 2012, Erica Cruz, a 23-year-old shepherdess was found dead in a mountainous area near Rosario de Lerma, Salta Province, in northwestern Argentina.[112] Claw incisions, which severed a jugular vein, indicated that the attacker was a felid; differential diagnosis ruled out other possible perpetrators.[b] There were no bite marks on the victim, who had been herding goats.[113] In 2019 in Córdoba Province, Argentina an elderly man was badly injured by a cougar after he attempted to defend his dog from it, while in neighboring Chile a 28-year-old woman was attacked and killed in Corral, in Los Ríos Region, on October 20, 2020.[114]

Fatal attacks by other carnivores such as feral dogs can be misattributed to cougars without appropriate forensic knowledge.[115]

Predation on domestic animals

The Cougar Hunt, a 1920s silent film created by the United States Department of Agriculture which explains the procedures to successfully hunt livestock-threatening cougars

During the early years of ranching, cougars were considered on par with wolves in destructiveness. According to figures in Texas in 1990, 86 calves (0.0006% of Texas's 13.4 million cattle and calves), 253 mohair goats, 302 mohair kids, 445 sheep (0.02% of Texas's 2 million sheep and lambs) and 562 lambs (0.04% of Texas's 1.2 million lambs) were confirmed to have been killed by cougars that year.[116][117] In Nevada in 1992, cougars were confirmed to have killed nine calves, one horse, four foals, five goats, 318 sheep, and 400 lambs. In both reports, sheep were the most frequently attacked. Some instances of surplus killing have resulted in the deaths of 20 sheep in one attack.[118] A cougar's killing bite is applied to the back of the neck, head, or throat and the cat inflicts puncture marks with its claws usually seen on the sides and underside of the prey, sometimes also shredding the prey as it holds on. Coyotes also typically bite the throat, but the work of a cougar is generally clean, while bites inflicted by coyotes and dogs leave ragged edges. The size of the tooth puncture marks also helps distinguish kills made by cougars from those made by smaller predators.[119]

Remedial hunting appears to have the paradoxical effect of increased livestock predation and complaints of human-cougar conflicts. In a 2013 study the most important predictor of cougar problems were remedial hunting of cougars the previous year. Each additional cougar on the landscape increased predation and human-cougar complaints by 5%, but each additional animal killed on the landscape during the previous year increased complaints by 50%. The effect had a dose-response relationship with very heavy (100% removal of adult cougars) remedial hunting leading to a 150% – 340% increase in livestock and human conflicts.[120] This effect is attributed to the removal of older cougars that have learned to avoid people and their replacement by younger males that react differently to humans. Remedial hunting enables younger males to enter the former territories of the older animals.[121][122] Predation by cougars on dogs "is widespread, but occurs at low frequencies".[123]

In mythology

The grace and power of the cougar have been widely admired in the cultures of the indigenous peoples of the Americas. The Inca city of Cusco is reported to have been designed in the shape of a cougar, and the animal also gave its name to both Inca regions and people. The Moche people represented the cougar often in their ceramics.[124] The sky and thunder god of the Inca, Viracocha, has been associated with the animal.[125]

In North America, mythological descriptions of the cougar have appeared in the stories of the Hocąk language ("Ho-Chunk" or "Winnebago") of Wisconsin and Illinois[126] and the Cheyenne, amongst others. To the Apache and Walapai of the Southwestern United States, the wail of the cougar was a harbinger of death.[127] The Algonquins and Ojibwe believe that the cougar lived in the underworld and was wicked, whereas it was a sacred animal among the Cherokee.[128]

panther is a large cat native to the Americas second only in size to the stockier jaguar They are not technically grouped with the true big cats as they are slightly smaller than other big cats and they lack the vocal physiology to roar unlike lions tigers leopards and jaguars Its range spans from the Canadian Provinces of the Yukon British Columbia and Alberta the Rocky Mountains and areas to the Western United States Their range extends further south through Mexico where they are found in nearly every state to the Amazon Rainforest and the southern Andes Mountains in Patagonia The puma as it is called in Spanish inhabits every mainland country in Central and South America making it the most widely distributed large wild terrestrial mammal in the Western Hemisphere and one of the most widespread on planet Earth It is an adaptable generalist species occurring in most American habitat types It prefers habitats with dense underbrush and rocky areas for stalking but also lives in open

Alaska The cougar is largely solitary by nature and considered both nocturnal and crepuscular although daytime sightings do occur It is an ambush predator that pursues a wide variety of prey Primary food sources are ungulates particularly deer but it also hunts smaller prey such as rodents Cougars are territorial and live at low population densities Individual home ranges depend on terrain vegetation and abundance of prey While large it is not always the apex predator in its range yielding prey it has killed to American black bears grizzly bears and wolf packs It is reclusive and mostly avoids people Fatal attacks on humans are rare but increased in North America as more people entered cougar habitat and built farms Intensive hunting following European colonization of the Americas and ongoing human development into cougar habitat has caused populations to decline in most parts of its historical range In particular the eastern cougar population is considered to be mostly locally extinct in eastern North America since the early 20th century with the exception of the isolated Florida panther subpopulation Contents 1 Naming and etymology 2 Taxonomy and evolution 2 1 Subspecies 2

from the Tupi language A current form in Brazil is sucuarana 3 In the 17th century Georg Marcgrave named it cuguacu ara Marcgrave s rendering was reproduced in 1648 by his associate Willem Piso Cuguacu ara was then adopted by John Ray in 1693 4 In 1774 Georges Louis Leclerc Comte de Buffon converted cuguacu ara to cuguar which was later modified to cougar in English 5 6 The cougar holds the Guinness record for the animal with the greatest number of names with over 40 in English alone 7 Puma is the common name used in Latin America and most parts of Europe The term puma is also sometimes used in the United States 8 9 10 11 The first use of puma in English dates to 1777 introduced from Spanish from the Quechua language 12 In the western United States and Canada it is also called mountain lion a name first used in writing in 1858 13 Other names include panther although it does not belong to the genus Panthera and catamount meaning cat of the mountains 14 Taxonomy and evolutionFelis concolor was the scientific name proposed by Carl Linnaeus in 1771 for a cat with a long tail from Brazil 15 The second half of the name concolor is Latin for of uniform color It was placed in the genus Puma by William Jardine in 1834 16 This genus is part of the Felinae 2 The cougar is most closely related to the jaguarundi and the cheetah 17 18 Subspecies nbsp South American cougar at Torres del Paine National Park in the Chilean part of PatagoniaFollowing Linnaeus s first scientific description of the cougar 32 cougar zoological specimens were described and proposed as subspecies until the late 1980s Genetic analysis of cougar mitochondrial DNA indicate that many of these are too similar to be recognized as distinct at a molecular level but that only six phylogeographic groups exist The Florida panther samples showed a low microsatellite variation possibly due to inbreeding 18 Following this research the authors of Mammal Species of the World recognized the following six subspecies in 2005 2 P c concolor Linnaeus 1771 includes the synonyms bangsi incarum osgoodi soasoaranna sussuarana soderstromii sucuacuara and wavula P c puma Molina 1782 includes the synonyms araucanus concolor patagonica pearsoni and puma Trouessart 1904 P c couguar Kerr 1792 includes arundivaga aztecus browni californica floridana hippolestes improcera kaibabensis

family Felidae is believed to have originated in Asia about 11 million years ago Mya Taxonomic research on felids remains partial and much of what is known about their evolutionary history is based on mitochondrial DNA analysis 17 Significant confidence intervals exist with suggested dates In the latest genomic study of the Felidae the common ancestor of today s Leopardus Lynx Puma Prionailurus and Felis lineages migrated across the Bering land bridge into the Americas 8 0 to 8 5 million years ago The lineages subsequently diverged in that order 17 North American felids then invaded South America 2 4 Mya as part of the Great American Interchange following the formation of the Isthmus of Panama 18 The cheetah lineage is suggested by some studies to have diverged from the Puma lineage in the Americas and migrated back to Asia and Africa 17 18 while other research suggests the cheetah diverged in the Old World itself 22 A high level of genetic similarity has been found among North American cougar populations suggesting they are all fairly recent descendants of a small ancestral group Culver et al propose the original North American cougar population was extirpated during the Pleistocene extinctions some 10 000 years ago when other large mammals such as Smilodon also disappeared North America was then repopulated by South American cougars 18 A coprolite identified as from a cougar was excavated in Argentina s Catamarca Province and dated to 17 002 16 573 years old It contained Toxascaris leonina eggs This finding indicates that the cougar and the parasite existed in South America since at least the Late Pleistocene 23 Characteristics nbsp Cougar skull and jawbone nbsp Front paw print of a cougar The head of the cougar is round and the ears are erect Its powerful forequarters neck and jaw serve to grasp and hold large prey It has four retractile claws on its hind paws and five on its forepaws of which one is a dewclaw The larger front feet and claws are adaptations for clutching prey 24 Cougars are slender and agile members of the Felidae They are the fourth largest cat species worldwide 25 adults stand about 60 to 90 cm 24 to 35 in tall at the shoulders 26 Adult males are around 2 4 m 7 ft 10 in long from nose to tail tip and females average 2 05 m 6 ft 9 in with overall ranges between 1 50 to 2 75 m 4 ft 11 in to 9 ft 0 in nose to tail suggested for the species in general 27 28 Of this length the tail typically accounts for 63 to 95 cm 25 to 37 in 29 Males generally weigh 53 to 72 kg 117 to 159 lb Females typically weigh between 34 and 48 kg 75 and 106 lb 29 30 Cougar size is smallest close to the equator and larger towards the poles 31 The largest recorded cougar shot in 1901 weighed 105 2 kg 232 lb claims of 125 2 kg 276 lb and 118 kg 260 lb have been reported though they were probably exaggerated 32 On average adult male cougars in British Columbia weigh 56 7 kg 125 lb and adult females 45 4 kg 100 lb though several male cougars in British Columbia weighed between 86 4 and 95 5 kg 190 and 211 lb 33 Depending on the locality cougars can be smaller or bigger than jaguars but are less muscular and not as powerfully built so on average their weight is less Whereas the size of cougars tends to increase as distance from the equator increases 31 which crosses the northern portion of South America jaguars are generally smaller north of the Amazon River in South America and larger south of it For example while South American jaguars are comparatively large and may exceed 90 kg 200 lb 34 North American jaguars in Mexico s Chamela Cuixmala Biosphere Reserve weigh approximately 50 kg 110 lb about the same as female cougars 35 Cougar coloring is plain hence the Latin concolor one color in the scientific name but can vary greatly across individuals and even siblings The coat is typically tawny but it otherwise ranges from silvery grey to reddish with lighter patches on the underbody including the jaws chin and throat Infants are spotted and born with blue eyes and rings on their tails 30 juveniles are pale and dark spots remain on their flanks 28 A leucistic individual was seen in Serra dos orgaos National Park in Rio de Janeiro in 2013 when it was recorded by a camera trap indicating that pure white individuals do exist within the species though they are extremely rare 36 37 The cougar has large paws and proportionally the largest hind legs in the Felidae 30 allowing for its great leaping and short sprint ability It is capable of leaping from the ground up to 5 5 m 18 ft high into a tree 38 Distribution and habitat nbsp A camera trap image of a cougar in Saguaro National Park ArizonaThe cougar has the largest range of any wild land animal in the Americas spanning 110 degrees of latitude from the Yukon Territory in Canada to the southern Andes in Chile 1 The species was extirpated from eastern North America aside from Florida but they may be recolonizing their former range and isolated populations have been documented east of their contemporary ranges in both the Midwestern US and Canada 39 The cougar lives in all forest types lowland and mountainous deserts and in open areas with little vegetation up to an elevation of 5 800 m 19 000 ft 1 In the Santa Ana Mountains it prefers steep canyons escarpments rim rocks and dense brush 40 In Mexico it was recorded in the Sierra de San Carlos 41 In the Yucatan Peninsula it inhabits secondary and semi deciduous forests in El Eden Ecological Reserve 42 In El Salvador it was recorded in lower montane forest in Montecristo National Park and in a river basin in the Morazan Department above 700 m 2 300 ft in 2019 43 In Colombia it was recorded in a palm oil plantation close to a riparian forest in the Llanos Basin and close to water bodies in the Magdalena River Valley 44 45 In the human modified landscape of central Argentina it inhabits bushland with abundant vegetation cover and prey species 46 Behavior and ecologyCougars are important keystone species in Western Hemisphere ecosystems linking numerous different species at many trophic levels In a comprehensive literature review of more than 160 studies on cougar ecology ecological interactions with 485 other species in cougar inhabited ecosystems have been shown to involve different areas of interaction ranging from the use of other species as food sources and prey fear effects on potential prey effects from carcass remains left behind to competitive effects on other predator species in shared habitat The most common research topic in the literature used here was the diet of the cougar and the regulation of its prey 47 Hunting and diet nbsp Cougar with deer killThe cougar is a generalist hypercarnivore It prefers large mammals such as mule deer white tailed deer elk moose mountain goat and bighorn sheep It opportunistically takes smaller prey such as rodents lagomorphs smaller carnivores birds and even domestic animals including pets 48 The mean weight of cougar vertebrate prey increases with its body weight and is lower in areas closer to the equator A survey of North America research found 68 of prey items were ungulates especially deer Only the Florida panther showed variation often preferring feral hogs and armadillos 31 Cougars have been known to prey on introduced gemsbok populations in New Mexico 49 Elsewhere in the southwestern United States they have been recorded to also prey on feral horses in the Great Basin 50 as well as feral donkeys in the Sonoran and Mojave Deserts 51 Investigations at Yellowstone National Park showed that elk and mule deer were the cougar s primary targets the prey base is shared with the park s wolves with which the cougar competes for resources 52 A study on winter kills from November to April in Alberta showed that ungulates accounted for greater than 99 of the cougar diet Learned individual prey recognition was observed as some cougars rarely killed bighorn sheep while others relied heavily on the species 53 In the Central and South American cougar range the ratio of deer in the diet declines Small to mid sized mammals are preferred including large rodents such as the capybara Ungulates accounted for only 35 of prey items in one survey about half that of North America Competition with the larger jaguar in South America has been suggested for the decline in the size of prey items 31 In Central or North America the cougar and jaguar share the same prey depending on its abundance 54 Other listed prey species of the cougar include mice porcupines American beavers raccoons hares guanacoes peccaries vicunas rheas and wild turkeys 55 Birds and small reptiles are sometimes preyed upon in the south but this is rarely recorded in North America 31 Magellanic penguins Spheniscus magellanicus constitute the majority of prey items in cougar diet in Patagonia s Bosques Petrificados de Jaramillo National Park and Monte Leon National Park 56 Although capable of sprinting the cougar is typically an ambush predator It stalks through brush and trees across ledges or other covered spots before delivering a powerful leap onto the back of its prey and a suffocating neck bite The cougar is capable of breaking the neck of some of its smaller prey with a strong bite and momentum bearing the animal to the ground 24 Kills are generally estimated around one large ungulate every two weeks The period shrinks for females raising young and may be as short as one kill every three days when cubs are nearly mature around 15 months 30 The cat drags a kill to a preferred spot covers it with brush and returns to feed over a period of days The cougar is generally reported to not be a scavenger but deer carcasses left exposed for study were scavenged by cougars in California suggesting more opportunistic behavior 57 Interactions with other predators nbsp Juvenile cougar in conflict with coyotes at National Elk RefugeAside from humans no species preys upon mature cougars in the wild although conflicts with other predators or scavengers occur Of the large predators in Yellowstone National Park the grizzly bear the black bear the gray wolf and the cougar the massive grizzly bear appears dominant often but not always able to drive a gray wolf pack an American black bear and a cougar off their kills One study found that grizzlies and American black bears visited 24 of cougar kills in Yellowstone and Glacier National Parks usurping 10 of carcasses Bears gained up to 113 and cougars lost up to 26 of their respective daily energy requirements from these encounters 58 In Colorado and California American black bears were found to visit 48 and 77 of kills respectively In general cougars are subordinate to American black bears when it comes to kills and when bears are most active the cats take prey more frequently and spend less time feeding on each kill Unlike several subordinate predators from other ecosystems cougars do not appear to take advantage of spatial or temporal refuges to avoid their competitors 59 60 The gray wolf and the cougar compete more directly for prey mostly in winter Packs of wolves can steal cougars kills and there are some documented cases of cougars being killed by them One report describes a large pack of seven to 11 wolves killing a female cougar and her kittens 61 while in nearby Sun Valley Idaho a 2 year old male cougar was found dead apparently killed by a wolf pack 62 Conversely one to one confrontations tend to be dominated by the cat and there are various documented accounts where wolves have been ambushed and killed 63 64 65 66 including adult male specimens 67 Wolves more broadly affect cougar population dynamics and distribution by dominating territory and prey opportunities and disrupting the feline s behavior Preliminary research in Yellowstone for instance has shown displacement of the cougar by wolves 68 One researcher in Oregon noted When there is a pack around cougars are not comfortable around their kills or raising kittens A lot of times a big cougar will kill a wolf but the pack phenomenon changes the table 69 Both species are capable of killing mid sized predators such as bobcats Canada lynxes wolverines and coyotes and tend to suppress their numbers 52 Although cougars can kill coyotes the latter have been documented attempting to prey on cougar cubs 70 In the southern portion of its range the cougar and jaguar share overlapping territory 71 The jaguar tends to take the larger prey where ranges overlap reducing both the cougar s potential size and the likelihood of direct competition between the two cats 31 Cougars appear better than jaguars at exploiting a broader prey niche and smaller prey 72 Social spacing and interactions nbsp Camera trap image of cougar in the Santa Susana Mountains northwest of Los AngelesLike almost all cats the cougar is a mostly solitary animal Only mothers and kittens live in groups with adults meeting rarely While generally loners cougars will reciprocally share kills with one another and seem to organize themselves into small communities defined by the territories of dominant males Cats within these areas socialize more frequently with each other than with outsiders 73 Home range sizes and overall cougar abundance depend on terrain vegetation and prey abundance 74 Research suggests a lower limit of 25 km2 9 7 sq mi and upper limit of 1 300 km2 500 sq mi of home range for males 75 Large male home ranges of 150 to 1 000 km2 58 to 386 sq mi with female ranges half that size 76 One female adjacent to the San Andres Mountains was found with a large range of 215 km2 83 sq mi necessitated by poor prey abundance 77 Research has shown cougar abundances from 0 5 animals to as many as seven per 100 km2 39 sq mi 78 Male home ranges include or overlap with those of females but at least where studied not with those of other males Home ranges of females overlap slightly Males create scrapes composed of leaves and duff with their hind feet and mark them with urine and sometimes feces 79 When males encounter each other they vocalize and may engage in violent conflict if neither backs down 80 Cougars communicate with various vocalizations Aggressive sounds include growls spits snarls and hisses During the mating season estrus females produce caterwauls or yowls to attract mates and males respond with similar vocals Mothers and offspring keep in contact with whistles chirps and mews 48 81 Reproduction and life cycle nbsp North American cougar cub in the Santa Monica Mountains nbsp Cubs Females reach sexual maturity at the age of 18 months to three years and are in estrus for about eight days of a 23 day cycle the gestation period is approximately 91 days 30 Both adult males and females may mate with multiple partners and a female s litter can have multiple paternities 48 Copulation is brief but frequent Chronic stress can result in low reproductive rates in captivity as well as in the field 82 Gestation is 82 103 days long 48 Only females are involved in parenting Litter size is between one and six cubs typically two Caves and other alcoves that offer protection are used as litter dens Born blind cubs are completely dependent on their mother at first and begin to be weaned at around three months of age As they grow they begin to go out on forays with their mother first visiting kill sites and after six months beginning to hunt small prey on their own 75 48 Kitten survival rates are just over one per litter 30 Juveniles remain with their mothers for one to two years 48 When the females reaches estrous again their offspring must disperse or the male will kill them Males tend to disperse further than females 83 One study has shown a high mortality rate amongst cougars that travel farthest from their maternal range often due to conflicts with other cougars 75 In a study area in New Mexico males dispersed farther than females traversed large expanses of non cougar habitat and were probably most responsible for nuclear gene flow between habitat patches 84 Life expectancy in the wild is reported at 8 to 13 years and probably averages 8 to 10 a female of at least 18 years was reported killed by hunters on Vancouver Island 30 Cougars may live as long as 20 years in captivity Causes of death in the wild include disability and disease competition with other cougars starvation accidents and where allowed hunting The feline immunodeficiency virus is well adapted to the cougar 85 Conservation nbsp Two cougar kittens at White Oak ConservationThe cougar has been listed as Least Concern on the IUCN Red List since 2008 However it is also listed on CITES Appendix II 1 Hunting it is prohibited in California Costa Rica Honduras Nicaragua Guatemala Panama Venezuela Colombia French Guiana Suriname Bolivia Brazil Chile Paraguay Uruguay and most of Argentina Hunting is regulated in Canada Mexico Peru and the United States 30 Establishing wildlife corridors and protecting sufficient range areas are critical for the sustainability of cougar populations Research simulations showed that it faces a low extinction risk in areas larger than 2 200 km2 850 sq mi Between one and four new individuals entering a population per decade markedly increases persistence thus highlighting the importance of habitat corridors 86 The Florida panther population is afforded protection under the Endangered Species Act 87 88 The Texas Mountain Lion Conservation Project was launched in 2009 and aimed at raising awareness of local people about the status and ecological role of the cougar and mitigating conflict between landowners and cougars 89 The cougar is threatened by habitat loss habitat fragmentation and depletion of its prey base due to poaching Hunting is legal in western United States In Florida heavy traffic causes frequent accidents involving cougars Highways are a major barrier for dispersal of cougars 1 The cougar populations in California are becoming fragmented with the increase of human population and infrastructure growth in the state 90 Human wildlife conflict in proximity of 5 km2 1 9 sq mi of cougar habitat is pronounced in areas with a median human density of 32 48 inhabitants km2 84 1 inhabitants sq mi and a median livestock population density of 5 3 heads km2 14 heads sq mi Conflict is generally lower in areas more than 16 1 km 10 0 mi away from roads and 27 8 km 17 3 mi away from settlements 91 Relationships with humansAttacks on humans In North America See also List of fatal cougar attacks in North America nbsp Mountain lion warning sign in California U S Due to the expanding human population cougar ranges increasingly overlap with areas inhabited by humans Attacks on humans are very rare as cougar prey recognition is a learned behavior and they do not generally recognize humans as prey 92 In a 10 year study in New Mexico of wild cougars who were not habituated to humans the animals did not exhibit threatening behavior to researchers who approached closely median distance 18 5 m 61 feet except in 6 of cases 14 16 of those were females with cubs 93 Attacks on people livestock and pets may occur when a puma habituates to humans or is in a condition of severe starvation Attacks are most frequent during late spring and summer when juvenile cougars leave their mothers and search for new territory 94 Between 1890 and 1990 in North America there were 53 reported confirmed attacks on humans resulting in 48 nonfatal injuries and 10 deaths of humans the total is greater than 53 because some attacks had more than one victim 95 By 2004 the count had climbed to 88 attacks and 20 deaths 96 Within North America the distribution of attacks is not uniform The heavily populated state of California saw a dozen attacks 1986 to 2004 after just three from 1890 to 1985 including three fatalities 97 Washington state was the site of a fatal attack in 2018 its first since 1924 98 Lightly populated New Mexico reported an attack in 2008 the first there since 1974 99 As with many predators a cougar may attack if cornered if a fleeing human stimulates their instinct to chase or if a person plays dead Standing still may cause the cougar to consider a person easy prey 100 Exaggerating the threat to the animal through intense eye contact loud shouting and any other action to appear larger and more menacing may make the animal retreat Fighting back with sticks and rocks or even bare hands is often effective in persuading an attacking cougar to disengage 92 94 When cougars do attack they usually employ their characteristic neck bite attempting to position their teeth between the vertebrae and into the spinal cord Neck head and spinal injuries are common and sometimes fatal 92 Children are at greatest risk of attack and least likely to survive an encounter Detailed research into attacks prior to 1991 showed that 64 of all victims and almost all fatalities were children The same study showed the highest proportion of attacks to have occurred in British Columbia particularly on Vancouver Island where cougar populations are especially dense 95 Preceding attacks on humans cougars display aberrant behavior such as activity during daylight hours a lack of fear of humans and stalking humans There have sometimes been incidents of pet cougars mauling people 101 102 Research on new wildlife collars may be able to reduce human animal conflicts by predicting when and where predatory animals hunt This may save the lives of humans pets and livestock as well as the lives of these large predatory mammals that are important to the balance of ecosystems 103 In South America Pumas in the southern cone of America often called Argentine cougars by North Americans are reputed to be extremely reluctant to attack man in legend they defended people against jaguars 104 The nineteenth century naturalists Felix de Azara 105 and William Henry Hudson 106 thought that attacks on people even children or sleeping adults did not happen Hudson citing anecdotal evidence from hunters claimed that pumas were positively inhibited from attacking people even in self defense In fact attacks on humans although exceedingly rare have occurred 107 108 An early authenticated non fatal case occurred near Lake Viedma Patagonia in 1877 when a female mauled the Argentine scientist Francisco P Moreno Moreno afterwards showed the scars to Theodore Roosevelt In this instance however Moreno had been wearing a guanaco hide poncho round his neck and head as protection against the cold 109 in Patagonia the guanaco is the puma s chief prey animal 110 Another authenticated case occurred in 1997 in Iguazu National Park in northeastern Argentina when the 20 month old son of a ranger was killed by a female puma Forensic analysis found specimens of the child s hair and clothing fibers in the animal s stomach In this area the coati is the puma s chief prey Despite prohibitory signs coatis are hand fed by tourists in the park causing unnatural approximation between cougars and humans This particular puma had been raised in captivity and released into the wild 111 On March 13 2012 Erica Cruz a 23 year old shepherdess was found dead in a mountainous area near Rosario de Lerma Salta Province in northwestern Argentina 112 Claw incisions which severed a jugular vein indicated that the attacker was a felid differential diagnosis ruled out other possible perpetrators b There were no bite marks on the victim who had been herding goats 113 In 2019 in Cordoba Province Argentina an elderly man was badly injured by a cougar after he attempted to defend his dog from it while in neighboring Chile a 28 year old woman was attacked and killed in Corral in Los Rios Region on October 20 2020 114 Fatal attacks by other carnivores such as feral dogs can be misattributed to cougars without appropriate forensic knowledge 115 Predation on domestic animals source source source source source source source source source source source source The Cougar Hunt a 1920s silent film created by the United States Department of Agriculture which explains the procedures to successfully hunt livestock threatening cougarsDuring the early years of ranching cougars were considered on par with wolves in destructiveness According to figures in Texas in 1990 86 calves 0 0006 of Texas s 13 4 million cattle and calves 253 mohair goats 302 mohair kids 445 sheep 0 02 of Texas s 2 million sheep and lambs and 562 lambs 0 04 of Texas s 1 2 million lambs were confirmed to have been killed by cougars that year 116 117 In Nevada in 1992 cougars were confirmed to have killed nine calves one horse four foals five goats 318 sheep and 400 lambs In both reports sheep were the most frequently attacked Some instances of surplus killing have resulted in the deaths of 20 sheep in one attack 118 A cougar s killing bite is applied to the back of the neck head or throat and the cat inflicts puncture marks with its claws usually seen on the sides and underside of the prey sometimes also shredding the prey as it holds on Coyotes also typically bite the throat but the work of a cougar is generally clean while bites inflicted by coyotes and dogs leave ragged edges The size of the tooth puncture marks also helps distinguish kills made by cougars from those made by smaller predators 119 Remedial hunting appears to have the paradoxical effect of increased livestock predation and complaints of human cougar conflicts In a 2013 study the most important predictor of cougar problems were remedial hunting of cougars the previous year Each additional cougar on the landscape increased predation and human cougar complaints by 5 but each additional animal killed on the landscape during the previous year increased complaints by 50 The effect had a dose response relationship with very heavy 100 removal of adult cougars remedial hunting leading to a 150 340 increase in livestock and human conflicts 120 This effect is attributed to the removal of older cougars that have learned to avoid people and their replacement by younger males that react differently to humans Remedial hunting enables younger males to enter the former territories of the older animals 121 122 Predation by cougars on dogs is widespread but occurs at low frequencies 123 In mythology The grace and power of the cougar have been widely admired in the cultures of the indigenous peoples of the Americas The Inca city of Cusco is reported to have been designed in the shape of a cougar and the animal also gave its name to both Inca regions and people The Moche people represented the cougar often in their ceramics 124 The sky and thunder god of the Inca Viracocha has been associated with the animal 125 In North America mythological descriptions of the cougar have appeared in the stories of the Hocak language Ho Chunk or Winnebago of Wisconsin and Illinois 126 and the Cheyenne amongst others To the Apache and Walapai of the Southwestern United States the wail of the cougar was a harbinger of death 127 The Algonquins and Ojibwe believe that the cougar lived in the underworld and was wicked whereas it was a sacred animal among the Cherokee 128 See alsoList of largest cats Pumapard hybrid of cougar and leopard
