In this video from Saskatchewan, a woman saw that two black bears were investigating the elevated stand she was occupying.  Soon one of them began to climb the ladder just as skilfully as you or I.  Maybe more skilfully than me, truth be told.

She tries to dissuade the bear from coming up higher by speaking to it so the bear knows that she is there.  She also begins to wag a finger at it, making it more curious, so it climbs higher.
