I know they can be one of the hardest animals to judge size of in the field, but what are some things to look for. I have a rug hanging on the wall from my first and only bear, a 13 year old sow, that weighed 278 hanging. I look at the distance between her ears and compare to what I see on hunting shows and her head looks enormous by comparison. I will be hunting over bait this year, and plan on setting up a few logs to help gauge the size. Are their any other features to look for?
