Post by: brokentrail on December 12, 2017, 11:57:53 AM: I think that already started/happened where I am. I saw a couple neighborhood bucks in the daylight that I've never seen before with does on December 6th. Saw two more on December 8th.

Post by: DaveMonti on December 12, 2017, 02:03:07 PM: Had a buck wander through my property a few days back. I have him on cam. I usually see ZERO all year until the 3-4 days of heavy rutting in late November, so one showing up 3 weeks later is rare. I have to think he was cruising.

Post by: Turner89 on December 12, 2017, 10:11:26 PM: I saw a 2point buck with 1doe on saturday, a nice buck with 3 does on Sunday, 5 does by themselves yesturday, and 4 does alone today. A friend shot a nice 3 point Sunday that his daughter doe bleeted in out of the timber.
Prior to saturday I couldn't find a deer to save my life. Lol
Something has changed.

Post by: fishnfur on December 14, 2017, 11:02:11 AM: Presumably there's still a little activity going on through the end of the month. Something like 98% of the does have been bred by the end of the first week of December. Depending on the number of doe in an area, there still could be one or two animals still estrus cycling, which will keep at least a few of the bucks up and searching through the end of the month.

In an area with low deer numbers, the chances are getting slimmer by the minute that bucks are still rutting, though one of the great hunters here told me that he rattled in a big buck for a friend on New Years Eve years ago. Never say die!

Just out of genuine curiosity, where does that 98% number come from? Is there research backing that number?

Post by: fishnfur on December 17, 2017, 05:26:32 PM: Glad you asked. This is a book/study published by the SOW back in the 50s. I got this copy for a buck on Amazon "new and used". Chock full of good biological info. on BTs. I was a little lucky to correctly quote the percentages in my earlier guess.

BTW, an interesting side to this information - these are dates that the does conceived. Other studies indicate that BT does don't normally don't conceive on the first estrus period, which means that if you count 21 days (+/-) forward (into Oct), the first estrus of many does occurs anywhere from mid-Oct through the end of that month, some a bit earlier, which accounts for the early showing of bucks we often see around 13 Oct - 20 Oct.

Hopefully. I still have a tag and will finally have a block of time after Christmas.
