Don't try to follow a deer. It will circle back if it senses it's being watched. Your chances of seeing a deer are best if you remain still. Picking a spot where you've seen one might be your best bet. Don't use the same spot for days, however.
Deer possess a keen sense of smell.
The longer you stay in one place, the longer your scent will stay there too. Intelligent predators, red and gray foxes can sense their prey from over the length of a football field away using their keen eyesight, smell and hearing. The body of a fox averages only about 23 inches long, but its 15-inch tail makes it seem like a much larger animal. Except for their coloring, the two foxes look much alike. With its brilliant orange fur and thick white-tipped tail, the red fox is much more distinctive looking than its gray cousin.
