I did some scouting last night on a Wildlife Mangement Area. I sat in my stand in the woods from 3pm to 7pm and did not see a thing. Then I realized that the deer were probably out in the fields eating. I got out of my stand and headed to the grassy fields around 7:15pm and sure enough, there they were. I spotted 13 deer and of those deer 8 were nice, mature looking bucks. The early muzzleloader season opens in 6 weeks here and I was wondering if it would be safe to assume the deer will still be using this field in 6 weeks vs. feeding off of acorns in the woods? When do they make the change from feeding in the fields to feeding off of the forest floor? Keep in mind that this is in Iowa and there are many agricultural fields that have not been harvest yet. Let me know what everyone thinks.
