Deer rut timing

So after having gone out west for the first time this year, and thinking about potential trips/locations for next year, I am trying to rationalize my way through deer rut timing.

Having hunted the southern half of MN my whole life, my opinion that the best time to be in the woods here and see mature bucks on their feet chasing is the first week of November. No doubt in my mind for MN. The text message pictures of big bucks killed by friends, and friends friends always peaks around November 4. The most pre-rut fighting and young bucks pushing around does really seems to come on around October 25, and carry to the point around Halloween when you start to see the bigger deer up during the day which pushes in spurts into mid November with bucks seemingly intermittently disappearing when they lock down with a doe. This is what we all look for, is the older bucks to get dumb, and show themselves during shooting hours. The bucks that survive will then sometimes become more visible again from November 25 or so and maybe into the beginning of December do I see a mature buck seemingly chasing again. Presumably this "second rut" that gets talked about. It is a real thing I think.

Now, when seeking guidance from those on this sight and others I talked to about hunting in MT the almost unanimous consensus was get as close to the last week of November as you can. Based on this, we did SE MT November 14-22 this year and saw rutting activity from both whitetails and mule deer. The biggest mule deer we saw were still at night, but they were definitely chasing. The whitetails seemed to be active, with many bucks out in the open pushing around and tending does. I can't say it looked like post rut, but I also can't say it was peak. We did see bucks bedded during the day, away from does, and it was 60 degrees at times.

Where we hunted in MT is north of where I live in SE MN, but is essentially between where I grew up and where our family deer camp is. I buy that deer further south rut later than further north, but do they rut later the further west you go too. Does it have something to do with timing of spring, more snow, wanting to drop fawns later, elevation, what?

The consensus also seems to be that mule deer rut later, but I swear on an Eastman's clip they said the opposite.

My struggle is when to plan vacation to go. It is very consistent that you guys that hunt the west a lot prefer that last week of November, but that seems to hold true from northern ID to southern CO. How can that be?

We are considering going back to SE MT or trying a black hills hunt in NE WY next year. I'm worried that we will be shooting ourselves in the foot if we go say from November 7-13 instead of 12-20 or something. Or would we be even better off going the week of thanksgiving? We will be hunting public land/BMAs so in my mind there is some factor of getting to a buck before someone else kills him, because you can't put your tag on a buck someone else did the week before. The other side of that is the bucks won't be showing themselves or moving through the stuff we can hunt until we get into the latter half of November.

Am I wrong in thinking that the first week of November in NE WY will have good chasing just like it does at the exact same latitude 9 hours east? I'm having a hard time convincing myself either way. A huge part of it is going, and seeing what we see, but other things can mess with single trips like weather, hunting pressure, etc.

Seeking the opinions and expertise of the eastmans crew.

Here in SW Colorado the rut usually starts around Thanksgiving. I saw the bucks nosing around the does this year starting the 15th of Nov and saw the rut continue until the 10 (or so) of December. I do know that whitetails tend to rut later and a lot depends on where they are. Down south it is December/January. I really think it depends on the weather, cooler weather, earlier rut.

I witnessed a mule deer breed a doe here in Nebraska on November 11th this year. We are usually at peak for both whitetail and mule deer around the 13th of November. The Nebraska Game and Parks has set this as the goal date for our November firearm season. It always starts the Saturday closest to November 13th and runs for 9 days. I have witnessed breeding as early as October 28th here and as late as January 6th. Some early first year fawns come into estrous their first year and that normally happens in January causing a 3rd rut.

In southern Wyoming we frequently saw mule deer rutting in early November but since our season were always in early October we didn't document any dates or pay special attention to rut timing. Hope this info helps.

In the west, for a true rut hunt, I like to be as close to Thanksgiving as possible. I've noticed that bucks tend to be more visible in daylight hours from around October 29 and later.

Great discussion guys! Thank you for the input.

This summer I went back through about 8-10 years of spring trail camera pictures and recorded all the dates that I had pictures of fawns that appeared to be around a week old or less. Some were obvious, with umbilical stalks still hanging, or being wet still, etc. Based on the median gestation I back calculated conception dates, and was shocked. Almost every date was in October. Basically from the 20th to the end of the month. There were a smattering of dates in very early November. Based on this I think we hunters probably call "rut" the periods between spurts of breeding when there is more seeking/chasing, and hence we see more deer.

From the above responses, I feel a little better about planning an earlier trip out west; like the end of the first week of November and into the second/third week.

I'm interested to hear more opinions/observations.

Tahoe, Yosemite,
I just drove from Washington to California yesterday and got home this morning. I won't say the roads I took, but we witnessed well over a couple hundred deer in huge packs usually with just one or two bucks around. We also witnessed a buck trying to breed on my way up to Washington with a doe in a herd of over 60 deer. So some are still in the rut. But we did see plenty of bucks by themselves away from these large herds.

The end of the first week of Nov into the 2nd and 3rd week has always worked out for me rut hunting in SE MT. We started 11/7 this year, rutting bucks all over, both MD and WT. Gets me home for Thanksgiving too. Later is usually better. Seen rutting behavior from late Oct into early Dec, often, and occasionally before and after.

John, keep in mind gestation periods can be affected by spring temperatures. The 200 day norm may not be normal for the deer in your area. There are some cool studies out there if you care to read on it.

I was told that if a doe/cow isn't bred in the first go-around, she'll comer into heat a month later. I once saw a bull elk breed a cow in the National Elk Refuge in November and Elk rut is in September/October. So buck whitetail seemingly running does is correct, they are looking for unbred females.

I usually hunt in Nebraska where there are mule deer and whitetail deer and generally we see more rut activity out of the whitetails in early November and more mule deer activity in mid November. Some years it seems like the whitetail buck activity is actually somewhat slow during the mid November rifle season and we find bucks on lock-down actually breeding the does instead of chasing or looking for them. Other years there are bucks on their feet at noon walking around looking for does like this year on the opener (11/14). Really varies from year to year but in general we see more rut activity out of the mule deer later than the whitetail deer.

Interesting, I have done no reading on the topic. Is it they will drop fawns sooner if it's warm (which would seem like a survival disadvantage with smaller fawns and potential for future cold/snow) or hold them longer if it's cold (survival advantage)? I just found it interesting that it was so consistent in about a 10 day period that was all in October. Maybe you're right and they are getting bred in November and are fawning early due to good weather. However, from 2005-2013 we had some very different springs and I didn't notice any variability by year.

Correct. I've seen spotted fawns in August, and have seen elk calves that were 1/2 the size of the others in November.

I am definitely not an expert on the subject but studied it a little in college. The studies suggest that the gestation period is shortened by a small percentage for each degree the temperature is above average during the spring.

It would seem you sample size should be large enough to average out the temperature factor?

The sample size is around 40-50 fawns over those years so certainly not too robust. I have witnessed only a handful of actual breeding events so I tried the fawn method to estimate.

I would say that November 10-20 are the best mule deer rut dates, with white tail being about a week later. That said pre-rut staging seems to start as early as mid October and bucks will remain cruising for missed or second cycle does clear into early December. I've had success on some of my biggest Blacktails and Muleys in the pre-rut cycle, so going the first week of November should still be a good hunt IMO
