according to the park. Visitor William Ogonowski was capturing video of the herd crossing when two bison began to get aggressive.
The video shows the animals bellowing and grunting as they move around cars stopped in the traffic jam. "Oh no, they’re fighting right in front of those people!" Ogonowski says.Then, just as Ogonowski notes how close the bison are to the cars, a bison suddenly head-butts the car directly in front.Bison are unpredictable, have injured more people in Yellowstone than any other animal and can run three times faster than humans, park officials said.
The park requires people to stay more than 25 yards away from all large animals, including bison and moose, and at least 100 yards away from bears and wolves.At least two gorings this year have been reported involving bison at the park.
In June, a Colorado man holding a child was tossed by a charging bison while he was holding a child. Both were OK. And in May, a 25-year-old Ohio woman got within 10 feet of a bison before it gored and tossed her, causing a puncture wound and other injuries.
