This is a cool thread.
I was deer mule deer hunting about 3 years ago, and while glassing from my spotting scope I spotted a herd or deer, all doe's. They were probably 700-800 yards away. Then just above them on a rock out cropping, I spotted a mountain lion with a couple cubs. She appeared to be looking down at the deer, which shortly after was confirmed when she came down and began her stalk on the deer. Both the deer and the lion left my view, but before that happened I saw the deer break into their typical escape mode, po go-ing away as they do. I didn't find any sign of a fresh kill over the next couple days, so I assume she failed?
One year while hunting turkey in SW New Mexico, I sat down just above a gob I had put to bed the night before, waiting for it to get light. As I was sitting there against the tree, I heard branches snapping and bark landing on the ground right in front of me. I figured it was turkey, probably hens, or maybe gobs that didn't sound off the night before. Then all of a sudden I heard this horrendous crashing, branches snapping, and then thud! A big black bear had fallen out of the tree just a few feet away. It got up and looked at me, then it just walked away, as if nothing happened. Come to find out, bears often fall out of tree's, I just happened to be next to the wrong/right tree.
I once had a mountain lion run me off from a roosted turkey I was putting to bed. Came back the next morning and found nothing but feathers. that one was a very close call, IMO, that cat was going to eat me and did get aggressive toward me, rather unusual I thought.
I was quail hunting with my German Short Hair, and watched as he nipped at the heels of a herd of 5 Oryx. He eventually got tossed through the air by one of the big bucks. This went on for a good 10 minutes or so, I ended up having to empty my bird shot at both him and the Oryx to break things up. I've actually had more than one encounter with Oryx, they are aggressive and have charged me more than once while quail hunting.
I got chased around a big pine tree by a large bull elk once. It was during the rut, and having heard a bull sound off several hundred yards away, I got this stupid idea to try something I saw on a video. Mind you, I wasn't hunting elk, I was hunting fall turkey. I took a large branch and started thrashing a tree. that bull came in hot, and when he saw me I thought he would just take off the other way. But to my complete surprise, he started chasing me around the tree. I barely escaped with my life. I ended up having to discharge a round from my shotgun to run him off.
I once had a bear come straight at me and my 3 yr. old son while I was pre scouting spring turkey. I was stopping at various spots trying to locate turkey with a box call, but all that responded were yotes, elk, deer and such. They would come in, see or smell us, and then depart. So when I came to the last spot and called, I heard something coming through the trees and naturally thought it was another deer or something. No, it was a sow with a cub, and she came charging straight at us, when she got right up to within several feet of us (we didn't move a muscle) she stood straight up, turned and went crashing through a stand of oak sapplings. As soon as she turned, I dropped my box call, grabbed my son and ran for the truck, I had to come back for the call later, after changing my under wear.
I've got more interesting stories for ya, I'll be here all week.
