Description
In the by, the North American cougar was separated into four subspecies. Recent taxonomic enquiry suggests that all N American cougars are substantially the aforementioned species, although there are some genetic and morphological differences related to geographic location.
The cougar has a lithe, muscular, compact, and deep-chested trunk, with a rounded and shortened caput and very visible whiskers. It has large eyes with round pupils, an adaptation to the cougar'southward nocturnal, or night time, behaviour. Some other distinctive characteristic of the cougar is its long tail: measuring up to a metre long, it is important for balance. It distinguishes the cougar from the lynx and the bobcat.
Cougars vary considerably in size and weight throughout their range, with individuals beingness larger and heavier in N America than in South America. Beyond the cougar'south range, developed males typically weigh almost one and a half times more than than females. In southwestern Alberta, for example, boilerplate weights for adult males and females are 71 kg and 4l kg, respectively. In North America, the total body length of developed male cougars is slightly more than ii m and of adult females, slightly less than 2 m.
Cougars in North America have brusque fur ranging in color from carmine, greyish, or tawny to nighttime brown. The backs of the ears and the tip of the tail are black, and there are blackness markings on the face. Kittens are spotted at birth, but lose the spots before the end of their starting time year.
The cougar is well adapted for grasping and cut upward big prey, with extremely stiff forequarters and cervix. Its muscular jaws, wide gape, and long canine teeth are designed for clamping downwards and holding onto casualty larger than itself, and its teeth are specially adapted for cutting meat and sinews.
Like all members of the true cat family, cougars have five digits on their forepaws (including the dewclaw) and iv digits on their hind paws. Each digit is equipped with a claw that remains subconscious when the animal is walking but that is used with deadly effectiveness when grasping prey. The cougar'due south forepart feet and claws are larger than its hind parts, allowing it to clutch large prey.
The cougar is known by many names, depending on local culture and legend. The Maliseet of New Brunswick call the cougar "pi-twal," meaning "the long-tailed 1." English language settlers along the Atlantic declension gave it the proper name "panther" after the Old Earth panther, which they had seen in animal shows, zoos, and artworks. The French explorers of southern Quebec and New Brunswick called information technology the "carcajou," a name afterwards given to the wolverine, causing great defoliation betwixt the two species in writings about them. The English proper noun "cougar" and the French "couguar," at present widely used in Canada, were adapted from the Brazilian native proper noun "cuguacuarana." The name "mountain lion" is extensively used in the western U.s.a., and "puma" is the native Peruvian proper noun.

Habitat and Habits
Cougars alive inside a "habitation range," where their needs for nutrient, h2o, and shelter are met. Inside their habitation range, cougars establish territories which they defend against intruders. Solitary animals, they discourage other cougars from entering their territory by leaving "scratches" or piles of leaves, pino needles, and dirt covered with urine and feces. They may as well leave claw marks on copse nearly the border of their territory. The scratches serve not merely to delineate the boundary but also to attract females in heat. Males and females also patrol their territory.
Male person cougars usually accept larger home ranges than females. The sizes of home ranges vary widely, just an average male dwelling range would embrace well-nigh 300 kmii, and a female's about one-half that. The territory of one male rarely overlaps with another male'due south territory, only it may overlap that of several females. Where home ranges do overlap, cougars still avoid each other and remain alone, gathering only to mate.
Females are less alone than males, remaining with their immature until the kittens are virtually two years old. Females with large litters and juveniles, or older kittens, typically have the largest dwelling ranges, because a large cougar family unit needs more food resources than a modest 1. In areas where prey is migratory, cougars may accept more than than one home range.
Cougar populations are composed of resident adults with kittens and transients. Transients about oftentimes are independent young cougars that have not nonetheless settled on their own territory, and they tend to be male person. Males typically disperse over a much greater altitude than females, and are known to travel more than 1000 km from the territory where they were born.
The number of cougars in a given area, or the animals' population density, depends on the number of available prey and suitable hunting sites. In western North America, population densities as loftier every bit four individuals per 100 kmtwo have been reported. Because big predators such as the cougar are at the top of the nutrient chain, a healthy cougar population is a adept indicator of a healthy ecosystem.
Unique characteristics
Cougars are extremely elusive and usually avoid direct contact with people. Masters of camouflage, they frequently remain subconscious when approached closely on foot. While tracking a cougar during wintertime, a researcher stepped within 1 m of its hiding place beneath a large spruce tree before the cat bounded out of its hiding place, racing abroad. Tracks and tail drag marks in the snowfall or mud are ordinarily the only evidence confirming the presence of these secretive, rarely seen animals.

Range
The distribution of the cougar has shrunk drastically since European settlement. In Canada, the cougar's range once mirrored that of deer, its favourite prey, extending from the west coast south of 60° N, across the prairies, through southern Ontario's forests to the lower Ottawa valley, the St. Lawrence valley of Quebec, and New Brunswick. Today, this big predator remains common but in the w. Notwithstanding, the cougar still occupies the most extensive range of whatsoever terrestrial mammal in the western hemisphere. Its northern limit is the Yukon border at 60° N, extending south to Patagonia, Argentine republic. It also lives at many altitudes, from body of water level to 4500 m, and in many climatic ranges, from dry deserts to deep, wet lowland tropical rainforests. Recent sightings have confirmed its presence in boreal wood habitat, where populations of white-tailed deer thrive.
In Canada, the distribution of what was in one case thought to be a distinct subspecies, Felis concolor couguar Kerr, has generated much controversy. During the concluding century, cougars have been reported in Ontario, Quebec, New Brunswick, and Nova Scotia; in fact, more than 1000 sightings have been reported since 1949 in Nova Scotia and New Brunswick alone. However, some of the sightings have proved to exist cougars from southern areas that had likely escaped or been released from captivity. There is little physical evidence, such as road kills or scats, that cougars have been present in eastern Canada since the nineteenth century.

Feeding
Cougars hunt mule deer, white-tailed deer, elk, moose calves, and in the westward, bighorn sheep. As opportunistic predators, eating a wide range of available species, they may also prey on birds and other mammals, including beaver, snowshoe hare, ground squirrel, and coyote. Where a diverseness of prey species are available, the diet of males and females can exist very different. For instance, in the Sheep River surface area of southwestern Alberta, moose calves account for nigh 85 percent of the winter prey of males, whereas deer and elk stand for 79 percentage of the diet of females. Cougars killed during territorial battles with other cougars may also be eaten by the successful animal. Cougars will occasionally scavenge besides, meaning they volition eat casualty killed by other animals.
Cougars rely on sight and hearing far more smell for hunting. They stalk their casualty to inside two or three corking leaps and and so launch a lightning-fast charge, striking their prey. Victims are most oftentimes killed past suffocation with a prolonged bite beyond the throat, collapsing the windpipe. The casualty's neck may also be broken with a single bite. Large prey, such as moose calves and elk, are unremarkably suffocated, whereas small prey, such as mule deer fawns, are more probable to dice from cleaved necks. A cougar will cover its kill with debris between feedings and so as to reduce the likelihood of scavengers locating and feeding on it.

Convenance
Cougars are polygamous, which means they may have more than one mate. A male with a large domicile range is able to breed with many females, and a resident male unremarkably attempts to maintain exclusive convenance rights with females inside his territory. Cougars may brood whatsoever time of the yr, although they well-nigh commonly breed in the winter. Males roam to breed with equally many females equally possible, sometimes travelling many kilometres a twenty-four hour period searching for receptive females. Contest for female breeding rights is intense, and males are often killed in territorial fights.
Females reach sexual maturity when they are two to iii years old. The gestation period lasts ninety days. They ordinarily give nascence to one to three kittens, and occasionally as many every bit six, only no more than three usually reach maturity. The female person finds a sheltered spot such as a cave or a windfall in gild to give birth. The kittens are built-in with their optics airtight, simply they grow quickly and their eyes become fully open up by the terminate of the second week. The female person nurses the immature for 4 to five weeks, and they remain with their mother for 18 to 24 months for food and to learn hunting skills. Females usually do not permit the male to approach the kittens as he may impale them because he does not recognize them as his ain offspring. When a resident male is killed and a new male arrives in the vacant territory, he may kill all the kittens that he finds because they are not his offspring and considering one time the immature are destroyed, the female will be more likely to breed once again, producing his offspring.
The mortality charge per unit amid kittens is high during the commencement year and later separation from the female. Equally soon as the juveniles are on their own, the female is probable to brood again. In a 7-yr study conducted in southwestern Alberta, females produced ane litter per year.

Conservation
Humans have killed cougars throughout history because of the animals' repeated attacks on vulnerable livestock and occasional attacks on people. Frequently these attacks occurred when a cougar was weakened by disease, parasites, or injury, making gratis-ranging or unsupervised livestock the easiest food source available. In many parts of the cougar's historical range, humans responded to these attacks by pursuing the cougar in smashing "ring" hunts, in which people surrounded a large area and collection all the animals in that area into a tight circumvolve. Predators, like the cougar, would exist killed, and the other animals would exist allowed to escape. Other ways of eradicating cougars have ranged from hounds, traps, and poison to bounties. Cougars are also killed through trophy hunting in jurisdictions where cougar hunting with hounds is still permitted—the normally elusive cougars are easily treed by hounds. These command techniques have resulted in a drastic decline in many cougar populations.
Cougars besides dice following serious injuries sustained when they pursue prey larger than themselves. In addition, young ordinarily don't survive when a female person with a litter dies, unless they are more than 9 to12 months erstwhile and can feed and defend themselves. Young cougars that take recently left their mothers are too more decumbent to starvation than their elders. Kittens, immature cougars, and adult males are sometimes killed by adult male cougars.
Originally designated "endangered" in 1978 by the Committee on the Condition of Endangered Wild fauna in Canada, since 1998 the cougar has been designated as "data deficient." This status was assigned because of the lack of genetic evidence to show that the eastern race was distinct; the lack of recent physical prove to bear witness that cougars still occur in eastern Canada; and some information suggesting that cougar sightings may be explained by escaped captive animals. There is, therefore, insufficient information to assign a status to this animal.
Western populations of cougar announced stable, and while the cougar has nigh disappeared from eastern Canada, there are signs that information technology may be moving east and repopulating old ranges. In recent years, a greater presence of cougars in primal and eastern Canada has been confirmed through trapping and DNA show. In Manitoba, ane cougar was shot in 2004 and a 2d was discovered in a hunter's coyote trap in 2005. These two specimens were the kickoff to exist brought to the attention of wildlife authorities in the province in 32 years. Further due east, hair samples retrieved in 2000 from a car that had supposedly collided with a cougar in Quebec and DNA analysis of pilus samples collected in 2003 from posts treated with cougar urine in New Brunswick have provided evidence of the cougar'due south being. With the removal of bounties and with enlightened management and conservation efforts for cougars, there is renewed promise that the species will persist throughout Canada if suitable habitat remains bachelor.
