Is it normal for a 700 grizzly to chatter?

Yes, it's normal for a 700-pound grizzly bear to exhibit chattering behaviors, often characterized by teeth grinding or jaw movements. This can occur during various situations, such as stress, excitement, or while communicating with other bears. While it's not a common behavior, it can be part of their vocalizations and body language. If observed in the wild, it's best to maintain a safe distance and avoid approaching the bear.
