GARDINER , Mont., May 11 (UPI) -- A group of tourists visiting Yellowstone National Park near Gardiner, Mont., have learned firsthand not upset a mama bear.
Montana Fish, Wildlife and Parks has released video of a black bear chasing a group of Yellowstone visitors away from her three 13-month-old cubs.
"It serves as a reminder that wildlife can be unpredictable," the agency said in a Facebook post. "For your safety and theirs, respect wildlife and give them room to roam."
Gibson said the mother would have been more protective of her cubs if they were younger.
The National Park Service warns visitors to stay away from bears, especially bears and their cubs.
