I’m not arguing about this. I am not saying the deer will or will not rut depending on the weather or location.
35 years of observations with my own two eyes while bowhunting the rut tell me the colder the weather, the more INTENSE the rutting activity…and I’m including the week or so leading up to and including the actual breeding period. The deer run harder, longer, and more feverishly with colder temps. I hunt in one little tiny place on planet Earth, and in that location beyond the shadow of a doubt the temperatures, especially when unseasonably warm or cold, have a great impact on the INTENSITY of the rut. I don’t need to read a book to verify what I have experienced first hand. Nor do I need someone else to verify my observations. I’d bet it is all relative to location though…like 90 degrees vs. 60 degrees down south - but that’s just a guess.
How the innumerable factors including biology of whitetail deer plays into this in other locations (smaller body size farther south you go) I have no idea. How things are down the road from my place, well I really don’t know that either I guess.
Moon phase with increasing moonlight and decreasing daylight are definitely triggers. Weather is not a trigger. If it was 100 degrees all during the rut, the does are still going to go into heat and the bucks are still going to breed them. I’m not sure if you are misunderstanding what I mean by “intensity” or what but no matter…good luck hunting.
