    Status Least Concern

    The cougar (Puma concolor), also commonly known as the mountain lion, puma, or catamount, is a large felid native to the Americas. Its range, from the Canadian Yukon to the southern Andes of South America (with expected permanent placement in Alaska in the next few decades), is the greatest of any large wild terrestrial mammal in the Western Hemisphere. An adaptable, generalist species, the cougar is found in most American habitat types. It is the second heaviest cat in the New World, after the jaguar. Secretive and largely solitary by nature, the cougar is properly considered both nocturnal and crepuscular, although sightings during daylight hours do occur. The cougar is more closely related to smaller felines, including the domestic cat (subfamily Felinae), than to any subspecies of lion (subfamily Pantherinae). However they are still considered big cats on this wiki.

    An excellent stalk-and-ambush predator, the cougar pursues a wide variety of prey. Primary food sources include ungulates such as deer, elk, moose, and bighorn sheep, as well as domestic cattle, horses and sheep, particularly in the northern part of its range. It will also hunt species as small as insects and rodents. This cat prefers habitats with dense underbrush and rocky areas for stalking, but can also live in open areas. The cougar is territorial and survives at low population densities. Individual territory sizes depend on terrain, vegetation, and abundance of prey. While large, it is not always the apex predator in its range, yielding to the jaguar, gray wolf, American black bear, and grizzly bear. It is reclusive and mostly avoids people. Fatal attacks on humans are rare, but have been trending upward in recent years as more people enter their territory. It shares a common ancestry with cheetahs.

    Naming and etymologyEdit

    With its vast range across the length of the Americas, Puma concolor has dozens of names and various references in the mythology of the indigenous Americans and in contemporary culture. However, it is referred to as "puma" by most scientists and "puma" is the preferred name in English, Spanish and Brazilian Portuguese. Despite being more consistently referred to as "puma" in the official language of 20 of the 22 countries in the Americas, the cat has many names in the United States and Canada, of which cougar, puma, mountain lion and panther are popular depending on local/regional vernacular. "Mountain lion" was a term first used in writing in 1858 from the diary of George A. Jackson of Colorado. Other names include "catamount" (probably a contraction from "cat of the mountain"), "panther", "mountain screamer" and "painter". Lexicographers regard "painter" as a primarily upper-Southern US regional variant on "panther". The word panther is commonly used to specifically designate the black panther, a melanistic jaguar or leopard, and the Florida panther, a subspecies of cougar (P. concolor coryi).

    P. concolor holds the Guinness record for the animal with the highest number of names, presumably due to its wide distribution across North and South America. It has over 40 names in English alone.

    "Cougar" may be borrowed from the archaic Portuguese çuçuarana; the term was originally derived from the Tupi language susua'rana, meaning "similar to deer (in hair color)". A current form in Brazil is suçuarana. It may also be borrowed from the Guaraní language term guaçu ara or guazu ara. Less common Portuguese terms are onça-parda (lit. brown onça, in distinction of the black-spotted [yellow] one, onça-pintada, the jaguar) or leão-baio (lit. chestnut lion), or unusually non-native puma or leão-da-montanha, more common names for the animal when native to a region other than South America (especially for those who do not know that suçuaranas are found elsewhere but with a different name). People in rural regions often refer to both the cougar and to the jaguar as simply gata (lit. she-cat), and outside of the Amazon, both are colloquially referred to as simply onça by many people (that is also a name for the leopard in Angola).

    In the 17th century, German naturalist Georg Marcgrave named the cat the cuguacu ara. Marcgrave's rendering was reproduced by his associate, Dutch naturalist Willem Piso, in 1648. Cuguacu ara was then adopted by English naturalist John Ray in 1693. The French naturalist Georges-Louis Leclerc, Comte de Buffon in 1774 (probably influenced by the word "jaguar") converted the cuguacu ara to cuguar, which was later modified to "cougar" in English.

    The first English record of "puma" was in 1777, where it had come from the Spanish, who in turn borrowed it from the Peruvian Quechua language in the 16th century, where it means "powerful".

    Biology and behaviorEdit

    Physical characteristicsEdit

    Cougars are slender and agile members of the cat family. They are the fourth-largest cat; adults stand about 60 to 90 cm (24 to 35 in) tall at the shoulders. Adult males are around 2.4 m (7.9 ft) long nose-to-tail and females average 2.05 m (6.7 ft), with overall ranges between 1.5 to 2.75 m (4.9 to 9.0 ft) nose to tail suggested for the species in general. Of this length, 63 to 95 cm (25 to 37 in) is comprised by the tail. Males typically weigh 53 to 100 kg (115 to 220 lb), averaging 62 kg (137 lb). Females typically weigh between 29 and 64 kg (64 and 141 lb), averaging 42 kg (93 lb). Cougar size is smallest close to the equator, and larger towards the poles. The largest recorded cougar, shot in Arizona, weighed 125.5 kg (276 lb) after its intestines were removed, indicating in life it could have weighed nearly 136.2 kg (300 lb). Several male cougars in British Columbia weighed between 86.4 and 95.5 kg (190 to 210 lb).

    The head of the cat is round and the ears are erect. Its powerful forequarters, neck, and jaw serve to grasp and hold large prey. It has five retractable claws on its forepaws (one a dewclaw) and four on its hind paws. The larger front feet and claws are adaptations to clutching prey.

    Cougars can be almost as large as jaguars, but are less muscular and not as powerfully built; where their ranges overlap, the cougar tends to be smaller on average. Besides the jaguar, the cougar is on average larger than all felids apart from lions and tigers. Despite its size, it is not typically classified among the "big cats", as it cannot roar, lacking the specialized larynx and hyoid apparatus of Panthera. Compared to "big cats", cougars are often silent with minimal communication through vocalizations outside of the mother-offspring relationship. Cougars sometimes voice low-pitched hisses, growls, and purrs, as well as chirps and whistles, many of which are comparable to those of domestic cats. They are well known for their screams, as referenced in some of their common names, although these screams are often misinterpreted to be the calls of other animals.

    Cougar coloring is plain (hence the Latin "concolor") but can vary greatly between individuals and even between siblings. The coat is typically tawny, but ranges to silvery-gray or 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; juveniles are pale, and dark spots remain on their flanks. Despite anecdotes to the contrary, all-black coloring (melanism) has never been documented in cougars. The term "black panther" is used colloquially to refer to melanistic individuals of other species, particularly jaguars and leopards.

    Cougars have large paws and proportionally the largest hind legs in the cat family. This physique allows it great leaping and short-sprint ability. The cougar is able to leap as high as 5.5 m (18 ft) in one bound, and as far as 40 to 45 ft (12 to 13.5 m) horizontally. The cougar's top running speed ranges between 64 and 80 km/h (40 and 50 mph), but is best adapted for short, powerful sprints rather than long chases. It is adept at climbing, which allows it to evade canine competitors. Although it is not strongly associated with water, it can swim.

    Hunting and dietEdit

    A successful generalist predator, the cougar will eat any animal it can catch, from insects to large ungulates (over 500 kg). Like all cats, it is an obligate carnivore, meaning it needs to feed exclusively on meat to survive. The mean weight of vertebrate prey (MWVP) was positively correlated (r=0.875) with puma body weight and inversely correlated (r=–0.836) with food niche breadth all across the Americas. In general, MWVP was lower in areas closer to the Equator. Its most important prey species are various deer species, particularly in North America; mule deer, white-tailed deer, and even bull elk are taken. Other species such as bighorn sheep, wild horses of Arizona, domestic horses, and domestic livestock such as cattle and sheep are also primary food bases in many areas. 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.

    Investigation in Yellowstone National Park showed that elk, followed by mule deer, were the cougar's primary targets; the prey base is shared with the park's gray wolves, with whom the cougar competes for resources. Another study on winter kills (November–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.

    In the Central and South American cougar range, the ratio of deer in the diet declines. Small to mid-size mammals are preferred, including large rodents such as the capybara. Ungulates accounted for only 35% of prey items in one survey, approximately half that of North America. Competition with the larger jaguar has been suggested for the decline in the size of prey items. Other listed prey species of the cougar include mice, porcupines, beavers, raccoons, hares. Birds and small reptiles are sometimes preyed upon in the south, but this is rarely recorded in North America. Not all of their prey is listed here due to their large range.

    Though 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.

    Kills are generally estimated at 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 at around 15 months. The cat drags a kill to a preferred spot, covers it with brush, and returns to feed over a period of days. It is generally reported that the cougar is not a scavenger, and will rarely consume prey it has not killed; but deer carcasses left exposed for study were scavenged by cougars in California, suggesting more opportunistic behavior.

    Reproduction and life cycleEdit

    Females reach sexual maturity between one-and-a-half to three years of age. They typically average one litter every two to three years throughout their reproductive lives, though the period can be as short as one year. Females are in estrus for about 8 days of a 23-day cycle; the gestation period is approximately 91 days. Females are sometimes reported as monogamous, but this is uncertain and polygyny may be more common. Copulation is brief but frequent. Chronic stress can result in low reproductive rates when in captivity as well as in the field.

    Only females are involved in parenting. Female cougars are fiercely protective of their cubs, and have been seen to successfully fight off animals as large as American black bears in their defense. 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. Kitten survival rates are just over one per litter. When cougars are born, they have spots, but they lose them as they grow, and by the age of 2 1/2 years, they will completely be gone.

    Young adults leave their mother to attempt to establish their own territory at around two years of age and sometimes earlier; males tend to leave sooner. One study has shown high mortality amongst cougars that travel farthest from the maternal range, often due to conflicts with other cougars (intraspecific competition). Research in New Mexico has shown that "males dispersed significantly farther than females, were more likely to traverse large expanses of non-cougar habitat, and were probably most responsible for nuclear gene flow between habitat patches."

    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. Cougars may live as long as 20 years in captivity. One male North American cougar (P. c. couguar) named Scratch, was two months short of his 30th birthday when he died in 2007. Causes of death in the wild include disability and disease, competition with other cougars, starvation, accidents, and, where allowed, human hunting. Feline immunodeficiency virus, an endemic HIV-like virus in cats, is well-adapted to the cougar.

    Social structure and home rangeEdit

    Like almost all cats, the cougar is a solitary animal. Only mothers and kittens live in groups, with adults meeting only to mate. It is secretive and crepuscular, being most active around dawn and dusk.

    Estimates of territory sizes vary greatly. Canadian Geographic reports large male territories of 150 to 1000 km2 (58 to 386 sq mi) with female ranges half the size. Other research suggests a much smaller lower limit of 25 km2 (10 sq mi), but an even greater upper limit of 1300 km2 (500 sq mi) for males. In the United States, very large ranges have been reported in Texas and the Black Hills of the northern Great Plains, in excess of 775 km2 (300 sq mi). Male ranges may include or overlap with those of females but, at least where studied, not with those of other males, which serves to reduce conflict between cougars. Ranges of females may overlap slightly with each other. Scrape marks, urine, and feces are used to mark territory and attract mates. Males may scrape together a small pile of leaves and grasses and then urinate on it as a way of marking territory.

    Home range sizes and overall cougar abundance depend on terrain, vegetation, and prey abundance. One female adjacent to the San Andres Mountains, for instance, was found with a large range of 215 km2 (83 sq mi), necessitated by poor prey abundance. Research has shown cougar abundances from 0.5 animals to as much as 7 (in one study in South America) per 100 km2 (38 sq mi).

    EcologyEdit

    Distribution and habitatEdit

    The cougar has the largest range of any wild land animal in the Americas. Its range spans 110 degrees of latitude, from northern Yukon in Canada to the southern Andes. Its wide distribution stems from its adaptability to virtually every habitat type: it is found in all forest types, as well as in lowland and mountainous deserts. The cougar prefers regions with dense underbrush, but can live with little vegetation in open areas. Its preferred habitats include precipitous canyons, escarpments, rim rocks, and dense brush.

    The cougar was extirpated across much of its eastern North American range (with the exception of Florida) in the two centuries after European colonization, and faced grave threats in the remainder of its territory. Currently, it ranges across most western American states, the Canadian provinces of Alberta, Saskatchewan and British Columbia, and the Canadian territory of Yukon. The Quebec wildlife services (known locally as MRNF) also considers cougar to be present in the province as a threatened species. The only unequivocally known eastern population is the Florida panther, which is critically endangered. There have been unconfirmed sightings in Elliotsville Plantation, Maine (north of Monson); and in New Hampshire, there have been unconfirmed sightings as early as 1997. In 2009, the Michigan Department of Natural Resources confirmed a cougar sighting in Michigan's Upper Peninsula.[82] Typically, extreme-range sightings of cougars involve young males, which can travel great distances to establish ranges away from established males; all four confirmed cougar kills in Iowa since 2000 involved males.

    On April 14, 2008, police shot and killed a cougar on the north side of Chicago, Illinois. DNA tests were consistent with cougars from the Black Hills of South Dakota. Less than a year later, on March 5, 2009, a cougar was photographed and unsuccessfully tranquilized by state wildlife biologists in a tree near Spooner, Wisconsin, in the northwestern part of the state.

    The Indiana Department of Natural Resources used motion-sensitive cameras to confirm the presence of a cougar in Greene County in southern Indiana on May 7, 2010.

    On June 10, 2011, a cougar was observed roaming near Greenwich, Connecticut. On June 11, 2011, a cougar, believed to be the same animal, was killed by a car on the Wilbur Cross Parkway in Milford, Connecticut. When wildlife officials examined the cougar's DNA, they concluded it was a wild cougar from the Black Hills of South Dakota, which had wandered at least 1,500 miles east over an indeterminate time period.

    In October 2012, a trail camera in Morgan County, Illinois snapped a photograph of a cougar, and on November 6, 2012 a trail camera in Pike County captured a photo also believed to be of a cougar.

    On November 21, 2013, a cougar was shot and killed near Morrison, Illinois in rural Whiteside County by the Illinois Department of Natural Resources.

    South of the Rio Grande, the International Union for the Conservation of Nature and Natural Resources (IUCN) lists the cat in every Central and South American country. While specific state and provincial statistics are often available in North America, much less is known about the cat in its southern range.

    The cougar's total breeding population is estimated at less than 50,000 by the IUCN, with a declining trend. US state-level statistics are often more optimistic, suggesting cougar populations have rebounded. In Oregon, a healthy population of 5,000 was reported in 2006, exceeding a target of 3,000. California has actively sought to protect the cat and a similar number of cougars has been suggested, between 4,000 and 6,000.

    In 2012 research in Río Los Cipreses National Reserve, Chile, based in 18 motion-sensitive cameras counted a population of two males and two females, one of them with at least two cubs, in an area of 600 km2, that is 0.63 cougars every 100 km2.

    Ecological roleEdit

    Aside from humans, no species preys upon mature cougars in the wild, although conflicts with other predators or scavengers occur. The Yellowstone National Park ecosystem provides a fruitful microcosm to study inter-predator interaction in North America. Of the three large predators, the massive grizzly bear appears dominant, often although not always able to drive both the gray wolf pack and the cougar off their kills. One study found that 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. Accounts of cougars and black bears killing each other in fights to the death have been documented from the 19th century. In spite of the size and power of the cougar, there have also been accounts of both brown and black bears killing cougars, either in disputes or in self-defense.

    Both cougars and their gray wolf rivals, are capable of killing mid-sized predators, such as bobcats and coyotes, and tend to suppress their numbers. Although cougars can kill coyotes, the latter have been documented attempting to prey on cougar cubs.

    In the southern portion of its range, the cougar and jaguar share overlapping territory. The jaguar tends to take larger prey and the cougar smaller where they overlap, reducing the cougar's size and also further reducing the likelihood of direct competition. Of the two felines, the cougar appears best able to exploit a broader prey niche and smaller prey.

    As with any predator at or near the top of its food chain, the cougar impacts the population of prey species. Predation by cougars has been linked to changes in the species mix of deer in a region. For example, a study in British Columbia observed that the population of mule deer, a favored cougar prey, was declining while the population of the less frequently preyed-upon white-tailed deer was increasing. The Vancouver Island marmot, an endangered species endemic to one region of dense cougar population, has seen decreased numbers due to cougar and gray wolf predation. Nevertheless, there is a measurable effect on the quality of deer populations by puma predation.

    In the southern part of South America, the puma is a top level predator that has controlled the population of guanaco and other species since prehistoric times.

    Because males disperse farther than females and compete more directly for mates and territory, they are most likely to be involved in conflict. Where a subadult fails to leave his maternal range, for example, he may be killed by his father. When males encounter each other, they hiss, spit, and may engage in violent conflict if neither backs down. Hunting or relocation of the cougar may increase aggressive encounters by disrupting territories and bringing young, transient animals into conflict with established individuals.

    HybridsEdit

    Main article: Pumapard

    A pumapard is a hybrid animal resulting from a union between a cougar and a leopard. Three sets of these hybrids were bred in the late 1890s and early 1900s by Carl Hagenbeck at his animal park in Hamburg, Germany. Most did not reach adulthood. One of these was purchased in 1898 by Berlin Zoo. A similar hybrid in Berlin Zoo purchased from Hagenbeck was a cross between a male leopard and a female puma. Hamburg Zoo's specimen was the reverse pairing.

    Whether born to a female puma mated to a male leopard, or to a male puma mated to a female leopard, pumapards inherit a form of dwarfism. Those reported grew to only half the size of the parents. They have a puma-like long body (proportional to the limbs, but nevertheless shorter than either parent), but short legs. The coat is variously described as sandy, tawny or greyish with brown, chestnut or "faded" rosettes.
