You would/ could have the same bucks breeding nov through Jan, since all they are waiting on is a mature doe to kick it off. It would also explain seeing a more intense rut in the area. Drawing more bucks in, while you still have the smaller number of doe in estrous at that time. By default, competition would be higher. Now THAT would be a solid theory. No real hard line. Just less intense rut noticed the further you get away from the core of the smaller genetic pool..... less competition. In my mind that's what makes areas like that special, more mature bucks pulled into a smaller area, for a small window of time. My .02
Wouldnt the flip side of this also be true in that there will be bucks leave Bankhead as well later in the year to go to these other areas in just the reverse process?......So what is it that's holding Bankhead stable over time?
