Mother bears have a fierce reputation, but they’re not the ones to worry about. Researchers led by the University of Calgary analyzed 59 fatal black bear attacks in the United States and Canada between 1900 and 2009. Most incidents could be blamed on hungry males. The bears most often attacked people traveling alone or in pairs, predominantly in August when black bears bulk up before denning.
