Some area s were hit with the EHD last year that took slot of the herd out , THEN of coarse the warmer than normal conditions this year during season , then the big crop of acorns in certain areas (northeast acorns was very selective areas or elevations where they acorns hit), then you got the Covid situation where some more people maybe back to work now. I know even here on Dec 31 it is even suppose to be up toward the 70 degree mark today , here in northeast Tn mountains. That is unseasonably warm.!!! So, Deer are moving more at night , (cooler temps) way more than they already usually move at night. Either way the deer are going to feed around 5 main times in a 24 hour period. All 5 of those times will not be just on Acorns , even during peak white oak season , they still need other woody browse , greens, and other things to complete their daily digestive track. A lot of Biologists and a lot of studies from different Universities will back this evidence up about the "wild" , (not the fenced in ones ), whitetail deer eating habits here in Tennessee. So IMO , it is due to a lot of different factors all coming together this year.
