Cougar

The cougar, scientifically known as *Puma concolor*, is a large wild cat native to the Americas.

It is one of the most widely distributed terrestrial mammals in the Western Hemisphere. This animal is considered a keystone species in its ecosystems. A keystone species is an organism that helps maintain the balance of its environment. The cougar interacts with 485 other species as a predator or as a provider of carcasses.

Because it affects so many other living things, the cougar is vital to the health of the natural world.

As an ambush predator, the cougar relies on stealth and power to hunt. It typically targets ungulates, which are hoofed animals like deer, but it also eats rodents.

To catch prey, the cougar uses its specialized anatomy. It has a round head and a powerful neck and jaw to grasp large animals. Its forepaws have five retractile claws, including a dewclaw, while its hind paws have four.

The cougar has proportionally the largest hind legs in the Felidae family. These large legs allow the cat to perform powerful short sprints and leap high into trees from the ground. This physical design makes it a highly effective hunter in diverse environments.

Cougars are highly adaptable generalists that live in many different habitats. Their range is massive, spanning 110 degrees of latitude.

They live from the Yukon in Canada, through the Rocky Mountains and Mexico, down to the Andes in Patagonia. They can inhabit forests, lowland or mountainous deserts, and open areas. They can even live at elevations up to 4,000 meters. While they prefer rocky areas and dense underbrush for stalking, they can also survive in human-modified landscapes. This flexibility allows them to exist in almost any American habitat type.

The history of the cougar's name is quite complex. It holds the Guinness record for the animal with the most names, with over 40 in English alone.

The name "cougar" was borrowed from the Portuguese *çuçuarana*, which came from the Tupi language. In the 17th century, Georg Marcgrave used the name *cuguacu ara*. Later, in 1774, Georges-Louis Leclerc, Comte de Buffon, changed this to *cuguar*. The name "puma" is the most common term in scientific literature. This name was introduced to English in 1777 from the Spanish word, which originated from the Quechua language.

Scientists have studied the cougar's evolution and classification for a long time. Carl Linnaeus first proposed the scientific name *Felis concolor* in 1771. Later, in 1834, William Jardine placed the species in the genus *Puma*.

Genetic studies show that cougars are most closely related to the cheetah and the jaguarundi.

Research suggests that the common ancestor of several cat lineages migrated across the Bering land bridge into the Americas one million years ago. Some scientists believe North American cougars were repopulated by South American cougars after the Pleistocene extinctions 10,000 years ago.

Physical size and weight can vary depending on where a cougar lives. Generally, cougars are smaller near the equator and larger toward the poles.

In North America, adult males average about 68 kilograms, while females average about 49 kilograms. In British Columbia, some males weigh significantly more. The largest recorded cougar weighed 163 kilograms in 1901. Their coats are usually a plain tawny color, ranging from silvery-grey to reddish. However, kittens are born with spots and blue eyes to help them blend into their surroundings.

Despite their large size, cougars face challenges from human activity. Intensive hunting after European colonization and modern development have caused populations to decline in many areas.

In eastern North America, the cougar is mostly locally extinct, except for the isolated Florida panther subpopulation. While fatal attacks on humans are rare, they have increased as people move into cougar habitats. Currently, the IUCN Red List classifies the cougar as a species of "Least Concern." This means that while they have lost much of their historical range, they are not currently at high risk of extinction globally.
