In the modern world there are getting to be fewer animals that have little to no exposure to man. Maybe baring Parts of Alaska even in rural areas there's farming ,ranching,oil&gas activities etc.where man invades the habitat regularly. Even in Wyoming we traveled from around Pinedale to Cody and it was obvious that the antelope ,elk and moose we saw, were acclimated to vehicles, livestock and humans.to a more or less degree. It's the same in the east. Given that, what common game animals do you find the spookiest around humans? In my observation baring cats which you rarely see it's the whitetail deer. Even around farms etc they seem to remain cautious and maintain a larger don't approach zone. I don't have much experience with pronghorn or mule deer but elk appear to adjust to humans much more readily than white tails. Hogs also seem to remain fairly furative but it may just be they are more nocturnal and we don't have that many here. What's been your experience?
