Estrus cycle ? Trickle rut?

[hammer33]

Im trying to get a handle on the estrus cycle of does. If peak rut is Nov 18th in my area, does that mean that almost all the reproductively mature deer will be cycling within a few days of that date?
If a doe gets missed, how many days until she cycles again? Is that a hard number or can they cycle early for a second time?

We seem to have a second bump of buck activity around December 20 each year here at the farm.
I have also seen wobbly new born fawns as late as September.

If I'm not mistaken. If I doe doesn't get bred when they are in estrus they will come back in about 30 days later. Bsk or someone smarter then me will chime in. But that's the "2nd rut" people always talk about. For us some of our best days especially if we get weather and arent tagged out are December 12 through the 15th.

I would say a lot of the does get bred. But, I'm sure some don't. I remember seeing a mature buck following a doe closely, a few years ago in February.

Why would All the doe's come in at the same time or even a week apart. I'd say they don't. I'd say some come in just about anytime in November and some even in December. They were all born on different dates. With the one's that didn't get bread coming back in 28 days later. And this years fawns coming in sometime in December Or January depending on when they were born. So the rut by definition is November to after season closes. Term peak rut is just when a larger percentage of the doe's are in heat.

The majority of does get bred about the same time. It's Nature's way of more fawns surviving.

For what it is worth- I have pics of a buck following a doe last year on Feb 14 and on Feb 28th.

My wife watched a doe in the stand last weekend she swore was pregnant. I hung a cam and got a pic of it. I would not be surprised. She is huge.

Why? Fawn survival as @Biggun4214 said. Through most of the whitetail range it's to synchronize fawns dropping 1) to swamp predators and 2) avoid weather issues. Deer in south Florida rut in July so they are dropping fawns outside of hurricane season, for example.

I have no idea what's going on with my place on the mountain. I've had a doe with a younger doe that I'm assuming is one of her offspring, and they haven't separated. A lot of new small bucks the last couple weeks and one or two older deer I've not seen before passing through. Saw what looked like a brand new rub about a week ago. No daytime activity. But I basically have a 1 to 1 ratio, if not more bucks than does in the area. Down in the valley, they were acting stupid a week and a half ago. Either I've missed it or they rut late up there.

There's always a ton of rut activities that we never see at night.
