The bear family is staying in a fairly small area where my cams see them regularly.
Brownie is now a lot bigger than Blackie. Brownie also plays very aggressively. Whether s/he is leaping out of trees onto Blackie or hitting Blackie in the face, I find myself incredulous that this is the same cub as the very timid Brownie who we first saw in May.
This is a really fun video of the two cubs playing. Be sure to notice the first scene in which Brownie ambushes Blackie, and then the scenes where the pair are like a pair of boxers.
