Grizzlies fighting over territory?

Grizzlies Fighting

Not a territorial fight rather siblings play-fighting. In the spring and early summer there are eight or ten bears we see on most days and there may be the same number further up the river. In the fall once the salmon arrive the number of bears in the area has been estimated as high as fifty. The interesting fact about the bears in the Glendale River valley is that there is so much food that it does not pay to fight because an injury at that time of the year means you may not survive hibernation.
