Much less common in Northwestern Ontario than in the past, although numerous sightings are still made every year. Although the mountain lion is a highly adaptive species, its range has been depleted in the wake of forestry, mining and urbanization. It can be sighted in a variety of habitats but prefers wooded areas with an abundant supply of food.


The mountain lion is a carnivore. White-tailed deer and moose make the better part of its diet but it will also feed on smaller animals such as hares, beaver, muskrats, mice and squirrels. When there is a shortage of natural game, it will on occasion prey on domestic cattle.


The mountain lion, like the bob cat and the lynx, is a shy and solitary animal. It only seeks others to mate. It generally stays away from civilization and goes where its prey goes. However, it can be dangerous to man when there is a shortage of food or when an unweary hunter or hiker strays into its space.
