A USGS grizzly bear researcher snapped this picture of a mother grizzly bear and her cub in Yellowstone National Park. Recent research shows that fffspring of grizzly bear mothers with a history of human-bear conflicts are more likely to be involved in human-bear conflicts than offspring of mothers without a history of human-bear conflicts.
