The cougar (Puma concolor) is a large cat of the subfamily Felinae. Native to the Americas, its range spans from the Canadian Yukon to the southern Andes in South America
and is the most widespread of any large wild terrestrial mammal in the Western Hemisphere.
It is an adaptable, generalist species, occurring in most American habitat types.
Due to its wide range, it has many names, including puma, mountain lion, catamount, panther and painter.
The cougar is the second-largest cat in the New World after the jaguar (Panthera onca).
Secretive and largely solitary by nature, the cougar is properly considered both nocturnal and crepuscular, although daytime sightings do occur.
Despite its size, the cougar is more closely related to smaller felines, including the domestic cat (Felis catus) than to any species of the subfamily Pantherinae.
