Two archery hunters shot and killed a grizzly bear after it knocked down and bit one of them near Yellowstone National Park on Sunday.
The two men were hunting elk in the Caribou-Targhee National Forest, west of Henrys Lake in Island Park, when the bear attacked them, Idaho Fish and Game Department said.
The adult male grizzly knocked over and bit one of the men.
The two friends responded by opening fire with their semi-automatic pistols, killing the bear. They phoned 911 soon after.
The injured man was taken by helicopter to Eastern Idaho Regional Medical Center where he was treated for non-life-threatening injuries.
The Idaho Fish and Game Department responded to the scene alongside other emergency services.
The decision to kill the bear was investigated by conservation officers who agreed the hunters had acted in self-defense, the Idaho Fish and Game Department said.
Supervisor Matt Pieron said: “I am extremely grateful that both of these individuals survived this encounter. I have had the opportunity to speak with the injured hunter and his family and they are truly wonderful people.
“I wish him a speedy recovery from his injuries and the trauma these two hunters experienced.”
Under the Endangered Species Act, grizzly bears are protected in the lower 48 states.
The Idaho Fish and Game Department reminded other hunters that encounters with grizzly bears can be anticipated in north Idaho and the Greater Yellowstone areas.
Government advice on the Yellowstone website warns visitors to “always stay at least 100 yards (91 m) away from bears and wolves, and at least 25 yards (23 m) away from all other animals, including bison and elk.”
