Killing a deer with a bow, on ground level, is a special treat. I use to say that one like that was worth 10 from a tree stand. When I first started bowhunting I used to spend a lot of time slowly moving through the woods trying to do so. I even developed a technique, for getting within bow range even after they had seen my movement.
While still hunting, if I could see a deer before it knew I was there, I would drop down and put the stems of several fallen leaves between my fingers, and a few in my mouth. Once that was done I would start my stalk. Sooner or later that deer would become aware of my presence, and become alert. With the deer keyed in on me I would release a leaf, and as it would float to the ground the deer would lock in on the movement of the leaf, forgetting about me. I would be downwind, so it couldn't smell me. I usually had some sort of camo on, so once I froze there wasn't any more movement, but still it knew that some sort of movement had alerted it. Once it saw the leaf fall, a very natural thing that it had seen all it's life, it was satisfied that everything was cool. To that deer, what had alerted it was just a leaf floating to the ground. Usually they would flick their tail and return to browsing or picking up acorns. Then I would continue my stalk until they noticed my movement again. Then I would repeat the process again, and again until I was in bow range. It didn't work every time, but the times that it did was very rewarding. Several time I have worked my way up to and inside of 20 yards. Once during a preseason scouting trip I showed a friend how I did this, and we managed to get inside of 10 yards on a doe with her fawn. We were on an open ridge, and had started the stalk from at least 200 yards away. We both ran out of leaves. Great Fun!!!
Later, after I became better at hunting feed trees, I quit slipping and started running. Trying to look at every tree in the area I was in, trying to locate primary feed trees. The name of the game for me, was the more trees I checked the better my chance's were to find what I was looking for, a primary tree for the entire area. When I did, it was almost a guaranteed shot opportunity. And, what I call a "high percentage hunt".
