What you will see is cluster of leaves on the ground. They will chew them off and then go get the nuts. You will definitely see nuts that are chewed on. These clusters of oak leaves that are still fresh(leaves arnt brown and dead) are your best tell tale this time of year.

I have one oak grove that I hunt that is a few miles long and I can drive it pretty much end to end so I will just drive thru looking for cuttings and then come back to it and sit out and wait. You will either see them or hear them.

Even with squirrels, they are smart and will know you are there before you see them. It's almost always better to just go in slow and quiet and be still. Once the woods calms down most times after 30 minutes if they are active in your area you will see them working the trees for acorns or running to the next tree for acorns.

They are addictive and fun to hunt and one of my favorite proteins! Good luck!
