Felis concolor

The cougar (Puma concolor), also puma, mountain lion, or panther, is a mammal of the Felidae family, native to the Americas. This large, solitary cat has the greatest range of any wild terrestrial mammal in the Western Hemisphere,^[3] extending from Yukon in Canada to the southern Andes of South America. An adaptable, generalist species, the cougar is found in every major New World habitat type. It is the second heaviest cat in the New World, after the jaguar, and the fourth heaviest in the world, after the tiger, lion, and jaguar, although it is most closely related to smaller felines.

A capable stalk-and-ambush predator, the cougar pursues a wide variety of prey. Its primary food is ungulates such as deer, particularly in the northern part of its range, but it hunts species as small as insects and rodents. It prefers habitats with dense underbrush for stalking, but it can live in open areas.
