No, the animals aren’t fleeing Yellowstone—It’s just social media hype

The bison are leaving! Grizzlies are leaving! The mountain lions are leaving! Social media videos—and rumors are running rampant. All the videos purport to come from Yellowstone National Park. Some show animals walking down roads as if they’re evacuating, and it’s sparked a flurry of online searches and wild speculation. The Yellowstone wildlife migration rumors are stoking fears of an impending volcanic eruption.

But, according to the National Park Service (NPS), there’s nothing to worry about.

AI-generation yields wildlife migration rumors

“These videos appear to be AI-generated and satirical in nature,” said Linda Veress, a spokesperson for the NPS, in a statement to ABC News. “Wildlife is not leaving Yellowstone National Park in large numbers. This rumor is false.”

For RVers planning a trip through America’s first national park, that’s good news.

Wildlife moves—but not like that

Seasonal movement of animals in and out of Yellowstone is nothing new. “There are normal migratory patterns, especially in the winter,” said Bill Hamilton, a wildlife biologist who has studied Yellowstone’s ecosystem for two decades. “But large-scale summer migrations like those shown in the videos just don’t happen.”

Yellowstone spans nearly 3,500 square miles across Wyoming, Montana, and Idaho, and is home to hundreds of animal species. Since there are no fences, wildlife is free to roam into and out of the park, and it often does. When it does, it’s on its own schedule.

Tom Murphy, a wildlife photographer who has been documenting Yellowstone for 50 years, explained it this way: “They’re free to come and go. There are known migratory paths for elk, deer, and bison.”

When winter rolls in and food becomes harder to find under snow, plant-eating animals like bison and elk may leave the park to find easier forage. Their predators often follow. “The mountain lions track the deer, and wolves follow the elk,” said Hamilton.

But right now, that’s not happening.

“This is a normal year,” said Murphy. “Elk and bison might head to higher ground to cool off or get away from bugs, but there’s no reason for them to be leaving the park in large numbers.”

Suspicious clips

Among the most suspicious clips is one that shows a large group of grizzly bears supposedly leaving Yellowstone together. But that’s a dead giveaway that something’s off.

“Grizzlies are solitary animals,” Hamilton said. “They don’t gather like that unless there’s a very high-value food source, like a salmon run or a carcass—and even then, not in a line walking down a road.”

Internet truth verifier Snopes examined a video like this one. Snopes.com examined a video shared by social media user Scott Whitehead, who calls himself an “animal expert.” It racked up over 6 million views on Facebook, 50,000 views on TikTok, and more than 130,000 likes on Instagram. The outfit found the video is neither recent nor from Yellowstone. It actually shows bears inside a drive-through wildlife park called Bear Country U.S.A., near Rapid City, South Dakota. The bears weren’t migrating—they were simply roaming inside the enclosed park where visitors drive through animal habitats.

Snopes used video forensics tools to trace the original source. The same footage was posted to Reddit in February 2025 and first appeared on TikTok in January 2025, shared by user @michellesijohn with hashtags like #bearcountry and #rapidcity. The behavior seen in the clip isn’t unusual for Bear Country. Similar groupings of bears crossing the road have been caught on camera there before, including in a 2017 YouTube video showing the same type of traffic-stopping bear behavior.

Another video shows a pack of mountain lions moving together, which experts say is completely fabricated. “Mountain lions don’t migrate,” said Murphy. “They follow a weekly loop through their territory. You’re not going to see them running down the road in a group.”

Animals forecasting eminent volcanic eruption?

Some online commenters have guessed that the animals might be sensing a looming eruption at Yellowstone’s supervolcano, which sits beneath the park. But there’s no sign of any geologic activity that would warrant alarm.

The Yellowstone Volcano Observatory, run by the U.S. Geological Survey, constantly monitors the park’s geothermal systems. Its current alert level is “normal” (Code Green). So, no, the supervolcano isn’t about to blow.

“Geologically, it’s going to erupt in the next 2 million years,” joked Murphy. “But probably not today.”

Blown out of proportion

Some videos may be based on actual footage taken in the winter, when bison sometimes walk along plowed roads to avoid deep snow. But those scenes involve just a small fraction of the roughly 4,500 bison in the park, Hamilton said.

“It was a very small percentage of the total herd size,” he noted. “People see these moments and blow them out of proportion.”

Fun turns to misinformation

While some of these viral videos may seem like harmless entertainment, wildlife experts say they can spread harmful misinformation.

“It undermines the public’s understanding of how nature works,” Hamilton said. “And that can be a problem when you’re trying to teach people about conservation.”

So, if you’re rolling into Yellowstone in your RV this summer, don’t worry—you’ll still have plenty of chances to spot wildlife. Just don’t believe everything you see on social media. After all, not one of the film clips showed a bear with a go-bag.
