Yellowstone Bison Licks Woman's Car in Super Close Encounter Caught on Film

A bison in Yellowstone National Park has been filmed licking a woman's car during an extremely close encounter.

There are approximately 5,450 bison living in Yellowstone. These are split into two main herds—the northern herd, which has just over 4,000 members, and the central herd, which is made up of around 1,300 bison.

"Why are you next to me?" The woman can be heard saying as the bison puts its face right up against the window.

A herd of bison can be seen grazing in the background. This bold bison, however, begins to sniff and lick the car. The woman can be heard laughing nervously as the bison continues to investigate. "He's licking the car!" she can be heard saying.

"Oh my god," another passenger says.

A male passenger can be heard saying that it must be because of salt on the car. The passenger may have been referring to road salt, used to prevent cars from slipping on ice.

Later on in the video, other Yellowstone visitors can be seen stopping to take photographs of the close encounter. The video ends with the bison putting its face close to the window and the woman squealing in fear.

Bison in Yellowstone are extremely accustomed to seeing cars and are not usually aggravated by their presence. They may sometimes approach out of curiosity, however, an the National Park Service (NPS) urges people to keep at least 25 years away from the large animals.

According to the NPS, bison have injured more people than any other animal at Yellowstone. They can weigh up to 2,000 pounds and are capable of throwing grown men in the air "like rag dolls," according to the park. A 2018 study showed that on average, bison injure one or two people in Yellowstone every year.

NPS said the herd instincts of bison mean they are especially sensitive to outsiders and are easily agitated. They are able to run up to 35 miles per hour.

They usually only injure people when they feel threatened, which is why Yellowstone National park urges visitors not to approach them. Bison do not usually pay attention to humans when they are relaxed. If they turn and make eye contact with a person, it's clear they are becoming irritated. Raising their tails is also another sign they might charge.
