A bison in California's Yellowstone National Park charged a young boy after a group of visitors got too close to the wild animal.

The incident was recorded and posted on Youtube and luckily, no one was injured. However, the Christian Post reported that the group of park visitors ignored "signs of agitation" exhibited by the beast and decided nevertheless to venture closer to the animal.

In the Youtube video, the man holding the camera says the bison looks agitated and as the group approaches closer, the animal is shown snorting and grunting, while shaking his head. After several seconds, the bison then charges and chases a young boy around some trees. Click here to watch the video.

Back in July, a bison ran at a 49-year-old Utah woman who was visiting Yellowstone National Park with her family and tossed her in the air, according to the Associated Press. That specific incident was the second time in the summer that a bison charged and injured a park visitor.

Al Nash, a Yellowstone spokesperson, told a radio station that the closest safe distance to a bison is 25 yards at a minimum. For bears, wolves and more dangerous animals, a safe distance is 100 yards away.

The National Park Service stated that the bison population in Yellowstone National Park is roughly between 2300 to 4500 animals. The park is also the only place in the United States where bison have continuously lived since prehistoric times. The largest bison population in the country on public land is in Yellowstone, according to the Service.

Bisons are to be feared if they begin running or if they get agitated. They can run more than 30 miles per hour and can pivot quickly. Signs to watch out for, the same with many other mammals, include grunting, shaking of the animal's head, snorting and pacing.
