RE: How can you tell when the deer are in rut?
you can tell that the rut is on when they all start running around humping trees. <img src=icon_smile_blush.gif border=0 align=middle>
Actually, although I don't know where you are I can tell you that at the latitude up here in Northern IL, the peak hits about mid November, but there is activity for weeks before that. I heard that it gets later the further South you are, and earlier if you are North.
Local biologists are the best souce because they track it every year.
Keep 'em all in the Bull.
