When I was about 19 driving down the road in Montana. There was a heard of Antelope running along the side of the road. All of a sudden out of no where this Eagle swooped down and hit a young lope in full stride. Killed it instantly. I have been told they hit them with their breast bone in the small of the back of their prey and break there back. Pretty ammazing! But then I get ammazed easy.
Do a You tube search (eagle attacks grizzly). Eagle wins or chases off the grizz.
