I called one in with a cow elk call once. Heard something that sounded like a bull thrashing a tree.
Gave a few chirps, the sound stopped, and there he was, coming straight in. I yelled, he pulled up and stared ne down from 30 yards, couldn't tell what I was.
He turned broadside and walked off real slow, stiff-legged. I don't know rheir body language but it was something along the lines of GFY.
A buddy and I have called in lions. We would spread out 40-50 yds apart and take turns calling. He shot his lion when it was 30 yds behind me.
Walking down a two track road in the dark with an archery client I was bugling bulls on an adjacent ranch when a black blur suddenly appeared coming right at us. I screamed, the bear veered, went by us at 10 ft without breaking stride.
Took 5 minutes at least before my heart started beating again…..
