A man was captured on video taunting a bison in Yellowstone National Park this week—in an incident that was criticized by U.S. park rangers.

“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 local station BNQT on Aug. 2.
