Cougar is a solitary animal. Only mothers and kittens live in groups, with adults meeting only to mate. It is secretive and crepuscular, being most active around dawn and dusk.
Due to excessive hunting following the European colonization of the Americas, and continuing human development of cougar habitat, populations have dropped in most parts of its historical range. In particular, the cougar was extirpated in eastern North America, except an isolated sub-population in Florida; the animal may be recolonizing parts of its former eastern territory.
