Hmm, a 3 legged bear, a cinnimon bear, & Is that a wolf in the third pic? Life is good and options appear unique, & plenty.
I don't know what kind of trail cam your using, but it takes beautiful pictures. Wow!
If you could get them right next to the bbl, the 2nd ring up is a decent way to judge a shooter, but from a short distance away from it they can look bigger due to depth perception. In that case look at the ears. If they're tall and pointy, & appear to be on top of his head, its a smaller bear, but if they're small, rounded, & on the sides of his head, Shoot.
Awesome pics. Thanks for posting them!
