Bowhunting whitetails is my greatest passion in life. For most of you reading this, I would assume that line of thought probably falls into your belief as well. I absolutely love the chess match that one plays when trying to hunt and ultimately harvest a mature buck. My favorite time of the year is hunting in September, because I can pattern and really learn how a deer lives in the summer, and then apply it to hunting him early in the season while he is still on that summer pattern. More often than not, when a buck sheds his velvet, there is a change in his testosterone levels. This usually goes hand in hand with a change in home range. This can take place anytime within a couple weeks of the velvet coming off the antlers, which usually occurs sometime in the first week or two of September. Based on that notion, most bucks home range will change sometime at the end of September, or very beginning of October.
