Brown Bear Behavior 111
Brown Bears are characteristically solitary animals. The majority of their interaction is at rivers and lakes where large populations of salmon hold and congregate. To maintain their personal space bears use different types of communication and behaviors. What is interesting is that their limited gamut of behaviors is not ritualized and their connotation is heavily reliant on the circumstance of the situation. It is important to concern yourself with different bear behaviors. At the same time, one must take into account the broad and common meaning in its specific context because each behavior is highly unique.
The following is from "The Bear Fact" published by the Alaska Natural History Association in cooperation with the National Park Service. Upon understanding some of the general meanings of their behaviors you will have a different perspective when on your bear viewing tours.

The vast majority of charges are false charges one in which the bear stops before making final contact. The intensity of the charge or associated vocalizations may vary, but it is distinct in that it is an aggressive or defensive act clearly directed at another bear or human. Bears may charge immediately, as a sow fearing for her cubs, or may emit stressed or erratic behavior before charging.
