Timing the Whitetail Rut

I recently got an email from the Westchester/Putnam branch of the QDMA in regards to timing the rut in Westchester County. I found it very interesting and thought I would share:



Fact: Whitetail deer have a gestation period that is approximately 198 days

By observing when the majority of fawns are born and counting back 198 days we can estimate when the peak of the rut takes place. This also gives us a parameter to look at in terms of timing your particular deer herd with does that cycle into estrous. As hunters how do we interpret fawn birth dates?

Generally speaking here in New York, our peak breeding takes place between November 10th and November 24th.  Following this, the majority of fawns will be born between May 27th and June 10th when summer foliage is at its peak. This is optimum for fawn survival because there is more food available in non-agriculture areas. The buck fawns born earlier in the spring become the bigger racked 1 1/2 year old bucks in the herd.

Does cycle every 28 days and does that are not bred during this time will cycle once again around December 5th through December 19th with births occurring between June 24th and July 10th. By this time, the deer have already been browsing on the foliage for two months and the foliage that is easiest for the fawns to reach is slowly disappearing. For new born fawns easy browse is becoming less available.

Populations with extremely skewed sex ratios and high deer densities, like Westchester County, breeding occurs again around January 5th (I witnessed a buck breed a doe from my office window on January 25th). These fawns will be born Late July and August and are at a big disadvantage to those born earlier. They will have lower weights and smaller antlers for the first few years of life unless adequate high quality food is available. Unfortunately, high quality food is not overly abundant for much of the lower Hudson Valley. The body and weight of these deer at age 1 1/2 will be smaller then those born two months earlier. These late born button bucks are usually the small spike bucks at age 1 1/2.

    I think a misconception is that does will only stand to be bred by the dominant buck or bigger bucks in their area. Fact is, a doe doesnt care who breeds her and will stand for who ever comes a long when shes ready. What this means is that there are very few does that arent bred when they come into heat the first time. The “second” rut basically consists of younger class deer that are just coming into estrus for the first time. This

We're out to change an industry and change the way you hunt. With more than 50 new pieces, 15 new textile developments, and a new pattern, we've got all our chips on the table. Here's a glimpse at the 2015 Whitetail Line.

Looks like it's official, archery open until 1/31 in Suffolk County: content.govdelivery.com/accounts/NYSDEC/bulletins/e50ad3

The changes to the Suffolk County deer hunting seasons and permit requirements are summarized as follows:

• Extends the regular (bowhunting) season for deer in Suffolk County through January 31;
• Expands the special firearms season for deer in Suffolk County to run from the first Sunday in January (January 4) through January 31 including weekends. The 2015 firearms deer season in Suffolk County will begin Sunday, January 4 and continue until January 31;
• Clarifies the Town permit requirements, landowner permission requirements and legal implements for the special firearms season. The adopted regulations also include a provision waiving the Town Permit requirement in any town which by local law has waived the town permit requirement. However, this aspect will not take effect before next season (January 2016);
• Increases permit quotas for each town to reflect current deer management needs and allow for additional access opportunities on state land.

What does a can of whipped cream have in common with a bucket of paint? They both look awesome when shot in slow motion.
