The cougar (Puma concolor), also commonly known as the mountain lion, puma, panther, or catamount, is a large felid of the subfamily Felinae native to the Americas.
Its range, from the Canadian Yukon to the southern Andes of South America, is the widest of any large wild terrestrial mammal in the Western Hemisphere.
Lexicographers regard painter as a primarily upper-Southern US regional variant on panther. It may also be borrowed from the Guaraní language term guaçu ara or guazu ara.
Less common Portuguese terms are onça-parda (brown onça, in distinction of the black-spotted [yellow] one, onça-pintada, the jaguar) or leão-baio (lit.
It also hunts species as small as insects and rodents.
On average, adult male cougars in British Columbia weigh 56.7 kg (125 lb) and adult females 45.4 kg (100 lb), though several male cougars in British Columbia weighed between 86.4 and 95.5 kg (190 and 211 lb).
The cougar is on average larger than all felid species apart from the lion, tiger, and jaguar.
Intensive hunting following European colonization of the Americas and the ongoing human development of cougar habitat has caused populations to drop in most parts of its historical range.
In particular, the North American cougar was extirpated in eastern North America in the beginning of the 20th century, except for an isolated Florida panther subpopulation.
