Bears in BC and Montana will come to a rifle shot, at times, expecting to 'take over' the kill. Oft times around here, those bears are removed from the gene pool.
I think this happens more with grizzlies, than with black bears.
A bow hunter up here have been followed by a grizzly sow with cubs when he and his son were hunting up Dunlevy Creek for elk. After the second day of being 'dogged'
by the bears, they packed up and left, never going back to that area.
A write up in the Bozeman paper (posted on another forum) I think it was, had a couple hunters call in a pack of wolves when calling elk. This was about 3 years ago.
2 friends of Taylor and I called 5 grizzlies while calling elk. They were sitting on their tree stands attached low on pine trees, their feet on the ground, & they separated by some bush.
Len didn't know the bears had come in- he heard the foot falls and though it was a bull with some cows. LOL They didn't think it was funny, one stood up only a few yards from Dave,
woofed at him, then they all took off running right past Len. Len noted he could have touched a couple with his bow tip as they ran past him. They were hunting with long bows - last time.
