I’m not trying to troll, I’m genuinely curious. Thinking about deer specifically, it doesn’t seem like visual camouflage would really help much when hunting them. Deer sense predators by sensitive hearing (big ears) and smell (long snout). Their eyes are on the sides of their head, so they detect motion rather than high-resolution.
So trying to blend in with the surroundings doesn’t seem to be an advantage in this case. Assuming all this, what’s the point of clothing with camo print on it?
I do just about everything I can to minimize me disturbing the area. So breaking up the contour, hiding my face (eyes and faces looking at you mean predators), and try to match camo to where I live and when I hunt. Not just for deer but also the birds, squirrels, etc because if they are acting scared they might alert a deer or at least put them on edge.
Also it might I can see wild life a little more naturally then if I was just screaming “human here!” Visually, audibly or through smell.
