This is the first time I have seen the sow and two cubs (2nd one not seen in this picture) grazing on grass. I'm told that when they start doing this it is a sign they are getting ready for the long winter and hibernation.

The 2 year old female cub is the shyer of the two cubs and will often hesitantly look back or take quick peeks, like this one.
