Deer will avoid bears, but they aren't frightened into the next county as long there's no direct aggression. The exception would be early in the year when does have young fawns, as bears do take a big toll on these.

The area I often hunt is a relatively wide open hillside. In the early mornings, it's not uncommon to watch 30-40 deer on a panorama of a mile or so making their way up to bedding areas. At the same time, there are often 1 or 2 bears working the slope, and I have seen as many as6 spread over the hillside. The deer will avoid them, butnot by very far and without any panic. A couple weeks ago, I observed one sow with 2 cubs scrounging whatever they could find while a pair of mule deer stood and watched less than 100 yards above them. Eventually the deer just grazed their way upslope.

Certainly these deer do not abandon their home area, as I see the same ones following the same routes day after day, in spite of the bears.
