You sure those "scrapes" weren't just beds? And as for the buck chasing a doe around in October, sounds pretty normal to me, could be just a doe that came into heat a little early. Bucks aren't picky, they'll take those does anytime they're ready.
I know people tend to think bucks necks get swollen when they get in the mood but I think it's just a sign of A-a mature buck with muscle mass that probably matches his big body and B- enlarged neck muscles due to rubbing and sparring with their buddies prior to game time.
Muledeer scrapes tend to be more mooselike than whitetail like. They dig out a pit, piss in it, roll around in it etc. Not a wallow like an elk. usually on steep ground, often near the peek of a ridgeline, usually in the open, with no licking branch like a whitetail. I'm sorry I have never taken the time to photo one. I saw a good one just the other day. Probably this fellows.......
As for your rutting observation. Think of a bell curve when you think of the rut. It starts out gaining gaining, peaks, then tapers back down, then think of a smaller bell curve following it. Hormones in deer are most effected by light duration. Kind of like leaves turning on a tree and then falling. Weather, moon(light) and temperature will effect the mood just like leaves falling off a tree. Depending on the elevation (high country deer) and all these little factors, you will see individual rut activity vary in time and cycle. The majority of doe are bred the first time around, then the second cycle starts and those that are missed are bred. I suppose there is even a third, but these are the critters that are born late, still have spots in the fall and rarely survive winter.
I think it's a misconception that because a buck has a big fat neck he is in full rut. I have seen old, mature bucks taken in September that have a big swollen looking neck. Makes for a cool mount with that thin September hair. I know people tend to think bucks necks get "swollen" when they get in the mood but I think it's just a sign of A-a mature buck with muscle mass that probably matches his big body and B- enlarged neck muscles due to rubbing and sparring with their buddies prior to game time. My opinion, I have been told I'm wrong before. Nice looking buck though.
