The doe I shot the other night illustrates something interesting that I have observed in the past. If a deer is calm and not alert or alarmed, and you double lung them, they usually run no more than 40-60 yards. In this case, She got to sniffing my trail in, then something made her bolt. But the fawn with her ran the other way, ending up under my tree. She came back on high alert, and I shot her. It looks in the video like she is about to fall down a couple of times in the open field, but then she would renew her energy and keep bounding. I believe this is because she already was on alert to danger around her when she was shot, and behind her as she ran. After running 150 yards, she fell down right among several other deer, who all bolted. I doubt she would have gotten back up, but I think all those other deer running got her back on her feet and she ran an additional 95 yards. Truly amazing animals.
