As you already are aware,each person has a unique personality.We are like snow flakes,no two are alike.
This principal applies to all animals as well. I have not met this female bear before.She was constantly staring at me.Whenever I encounter this behavior I know the bear is fearful of me.So I try not to move while they are watching me. But sometimes no matter what I do,they are just too skittish & run off.Thats what she did a few seconds after I took this shot. Some bears are just very hard to get to know & are best left alone.
