I think (Emphasis on "think") that they have multiple cores within their home range. What you're seeing is what I see here every year. Their summer core is different when the food source changes. I'm seeing it change, here, right now. they're getting off the beans and onto the mast crops....although the beans are greener than ever and plentiful. The acorns are falling, though.
This is pretty accurate.
It's common sense where a whitetail goes.. but so many over-look it because we all think we are such an advanced civilization.. and we forget basic principles.
First.. remembering that whitetail have been on this earth for like 1 miilion years. Only over the last 100 years or so has man been cultivating the landscape and replacing woods with farmland.
It's natural instinct that a whitetail flocks to acorns this time of year. It is the main source of nutrition that will see them through winter. It was not long ago when bean and corn-fields did not spread rampant across the countryside.
Whitetail are just going where mother nature has intended them to go to for the last 100,000+ years.
Seek the acorns and you will find your deer.
I could elaborate further.. but I hate typing.
