I have been a "whitetail nut" for about sixty years hunting them in various terrains with bow, muzzleloader, and rifle, from the small wood lots of the Northeast(where I reside), to more desolate area of the Northwest. While their territory make-up may vary, their behavioral traits are consistent and largely dependent their perception of danger….The older the buck, the greater their accumulated knowledge base. The only time you might catch him off-guard is for a short period during the rut when his senses are preoccupied. Otherwise, he WILL know that you are in his territory and determine that you are a danger if he sees, hears, or smells you……….
He possesses the rare trait amongst game of having "no" curiosity, If you are lucky enough bump him, won't stop and look back.
For a couple of decades, one of favorite methods for hunting the whitetail is hunting the Western river beds that connect the farming areas and the foothills. Quite often the whitetails regularly travel theses area. It does require some homework to establish that good bucks have been spotted in the connecting farming areas. Pick areas that tend to "funnel" the deer movements. IMO, this form of hunting is "perfect" for the long range hunter, and can provide an opportunity to harvest a mature buck. While most of the action is early and late in the day, the big guys can be spotted at any time….I'll post at a distance( usually about 500 yards), well concealed on an adjacent hill with binoculars and spotting scope. Out of sight,hearing, and smell. Lots of patience and looking, and, when a shot presents itself…Pick the shot carefully. This method isn't for everybody, and, I rarely see other hunters. But when I do, I can often observe from my position, the skilled evasiveness of the un-detected, mature whitetail at work….
I spotted this buck in a thicket at 1000 yards on a Monday. After several "no shot" sightings of him during the week, I got my shot at 10AM a few days later..
My shooting nest, and double drop-tine buck. After seeing him I passed on a few other nice bucks…Glad I did!
