Rangers at Yellowstone National Park are calling the actions of a man who taunted a bison “reckless, dangerous and illegal” as they investigate his stupid stunt.

“We need people to be stewards of Yellowstone, and one way to do that is to keep your distance from wildlife,” park superintendent Dan Wenk told BNQT.

Bystander Lindsey Jones of Elko, Nev., captured video of the shorts-wearing man beating his chest as he approached the animal, which promptly charged at him on the two-way road in Hayden Valley.

The knucklehead walked away unharmed.

Visitors are required to stay at least 25 yards from animals such as bison and elk, and 100 yards from bears and wolves, park rules state.

“People who ignore these rules are risking their lives and threatening the park experience for everyone else,” Wenk told BNQT.

At least one person is gored by a bison each year at the famed park.

On June 6, 59-year-old Kim Hancock of Santa Rosa, Calif., was gored by a bull bison at Fountain Paint Pot in the Lower Geyser Basin, according to the park.

Hancock, who was among a crowd of people that approached within 10 yards of the bison, was treated for a hip injury. It was the second incident of a bison injuring a visitor this year, the National Park Service said.

There was one incident in 2017 and five in 2015, according to BNQT.
