While they may not be the most social animals in the world, Yellowstone National Park does have cougars. Mountain lions, also known as mountain lions or cougars, can be found throughout the wooded areas of the United States – but have you seen them? Is it possible to see a mountain lion in Yellowstone, especially if you’ve never seen a mountain lion in the wild before?
In this article, we explain everything you need to know about Yellowstone’s mountain lions, including what time of day they are most active and whether they can be seen anywhere in the park. We’ll also discuss proper etiquette regarding Yellowstone’s wildlife and whether mountain lions are a regular sight. Now let’s start talking about the cougars in this beautiful national park!

How many mountain lions are there in Yellowstone National Park?

For a number of reasons, it is impossible to know exactly how many mountain lions live in Yellowstone National Park. These animals are very elusive and stealthy, making them difficult to track. Additionally, mountain lions occupy a wide range of territories, and many disputes have ended in the displacement of male mountain lions outside of the Yellowstone area.
Yet despite all of these things, Yellowstone Rangers have integrated a lot of modern tracking equipment throughout the park to better track elusive species such as mountain lions. because of this, They estimate that at any given time, there are 30-45 mountain lions of various ages and genders in Yellowstone.
What’s particularly interesting is that the longer the mountain lion lived in Yellowstone, the greater its authority over the species. For example, some of the oldest male cougars living in national parks occupy the largest territories and give birth to most of the pumas season after season.

Cougars vary in size by sex, with females being smaller than males. They weigh an average of 85-170 pounds and are 6-8 feet long including the tail. Hunting of cougars or any other animals is not permitted within the park boundaries, with an average age of 8-15 years depending on size and sex.
When are mountain lions most active in Yellowstone National Park?

Cougars are most active during the day, especially at dawn and duskThis is because dawn and dusk are the most active times for their preferred prey, namely deer and elk. Cougars will hunt a deer or elk and feed on the carcass for up to 5 days, depending on size. However, most cougar prey end up in grizzly bears or wolves, as these animals remain the common cougar’s top predators.
Although this time of day is when cougars are extremely active, it’s unlikely you’ll see them while you’re at the park. That’s because cougars are extremely secretive and solitary, which is why Yellowstone National Park rangers use long-range cameras and advanced tracking equipment to get to know them!
As far as the best time of year for cougars to be most active, winter is more promising than summer. This is because many different animals descend from the northern peaks and into the lower valleys due to the cold and cold. From the safety of your vehicle, there are many species to see, which is especially good news if you happen to come across a cougar. Always keep at least 100 yards away from any predators in Yellowstone National Park!
Where can you see mountain lions in Yellowstone National Park?

Unfortunately, it’s unlikely you’ll see or catch a glimpse of a mountain lion during your visit to Yellowstone National Park. This is because these animals are elusive and prefer to live in seclusion in rocky, wooded areas. Cougars, however, often hunt in the upper reaches of Yellowstone’s northern ridge. With any luck, you might spot a mountain lion in the area, although this is extremely rare.
Mountain lion kittens are born year-round, but their favorite mating season in Yellowstone is from February to the end of May. This means that puma cubs are born in remote parts of the park throughout June to September. Seeing young cougars come out of their den for the first time may sound like a once-in-a-lifetime experience, but it’s unlikely that mother cougars want you to know where their dens are in the first place!

I am broadly interested in how human activities influence the ability of wildlife to persist in the modified environments that we create.
Specifically, my research investigates how the configuration and composition of landscapes influence the movement and population dynamics of forest birds. Both natural and human-derived fragmenting of habitat can influence where birds settle, how they access the resources they need to survive and reproduce, and these factors in turn affect population demographics. Most recently, I have been studying the ability of individuals to move through and utilize forested areas which have been modified through timber harvest as they seek out resources for the breeding and postfledging phases. As well I am working in collaboration with Parks Canada scientists to examine in the influence of high density moose populations on forest bird communities in Gros Morne National Park. Many of my projects are conducted in collaboration or consultation with representatives of industry and government agencies, seeking to improve the management and sustainability of natural resource extraction.
