This just happened last night! Momma bear and her two cubs, one of which climbed up a tree lightening fast when I went outside and the other not quite ready. The little one kept looking up and assessing the tall tree repeatedly (which was pretty cute) and decided to stay close to mom.
Momma kept one eye on the her cub that was already up the tree and she made eye contact with me, but when she went for a second helping (from my now broken latched bear resistant toter that she moved and got into with complete ease ) I wanted her to stop, so I didn't have garbage all over my yard--a little was fine, but seconds... no ;)
Please excuse the quality of these images, it was nearly dark and I was pushing my settings.
