Dangers to humans

Bison are among the most dangerous animals encountered by visitors to the various North American national parks and will attack humans if provoked. They appear slow because of their lethargic movements but can easily outrun humans; bison have been observed running as fast as 65 to 70 km/h (40 to 45 mph). Bison may approach people for curiosity. Close encounters, including to touch the animals, can be dangerous, and gunshots do not startle them.

Between 1980 and 1999, more than three times as many people in Yellowstone National Park were injured by bison than by bears. During this period, bison charged and injured 79 people, with injuries ranging from goring puncture wounds and broken bones to bruises and abrasions. Bears injured 24 people during the same time. Three people died from the injuries inflicted—one person by bison in 1983, and two people by bears in 1984 and 1986.
