Not sure of the site but I can tell you this. I was told look at the ears. Look at his legs. That is not true. A little bear will have little ears and they all appear to be on the side of their heads, They all look the same. When I was on my bear hunt I saw a good bear the first day and never picked up the gun cause I was didn't know if it was a good bear or not. I watched him so long I could decide. The best way I know is to have something to compare him to like a large rock or stump. Good luck but I will keep looking
