Funnel is fine, but I think that term is way overused. What does it mean, and how do you determine? Dad always said that hunting "funnels" is great, but all of them that he had ever seen were oily and hanging on garage walls.
Any deer movement is dictated by such a multitude of factors - terrain, wind currents, cover/foliage, wind currents (again, not a mistake
), human movement, year to year crop rotation, and subtle transitions/combinations of any of the above as well as others things that I think most "funnels", if you will, or factors influencing the patterns of movement are too subtle to see upfront.
The big factor that is so often overlooked, underappreciated, or totally missed is how what you are looking at fits into the big picture of a deer's life. The movement in the 40 or 80 or 200 acre property you are on is a TINY picture of the overall deer movement in the area. Where are they going from/to, and why? is a question that is VERY difficult to ascertain in the big picture of a deer's home range - especially a buck on the move in November.
I find that my best rut stands have evolved over years and years of observation, scouting and plain hard work, along with LOTS of noodling over in my mind what is going on.
My starting point is looking for big rubs...not just any big rubs, but the big signpost rubs created year after year. Even old rublines that haven't been hit for several years, but were signposts in their day, mean more to me than last year's rut sign. Keep in mind a buck standing over/guarding an estrous doe during the active breeding period will create many, many rubs and tear up the woods in a relatively small area out of exhibiting dominance to other bucks. This can look GREAT when you find it, but all it means is that for a 12 to 36 hour period a buck was there with a doe breeding. Good to remember the area, but I don't plan on setting up on that sign next year. The true signpost rubs develop where they do for a reason. I'm looking for generational buck travel patterns from years and years of use.
After the fact you could probably define these as "funnels", but I bet the "funnel" is so subtle on 90% of them you would never see it without the generational buck sign.
