Two interesting events happened to me showing how animals adapt to human actions. Several years ago I dropped two does in Warren County, NJ. I dress both of them out and dragged one to my car. On the way down the hill I passed a fox heading up to the gut pile that was decidedly annoyed that he had to step off the trail for me. When I returned to the second deer; he took about six steps and sat down waiting for me to leave before he went back to work on the pile. Didn't show any interest in the deer. Must have known to leave it alone for his own well being.
Another time I was busy dressing a deer when a noise above me made me look up. In the tree above me was 4 turkey vultures waiting for me to finish. Have to admit I hurried that job up and got out of there. Those birds eyeing me was a little unnerving.
