So the question is how the heck do you pinpoint what leaves they are feeding on? One guy said red leaves are preferred, one said poplar leaves, how do I possibly scout for this? I do agree some other food source has taken over, we have zero acorns let alone oaks for miles. I wish I knew how I could pinpoint what leaves they prefer, we have sugar maple, poplar, beach, and apple trees, what leaves should I focus on? This could truly be why I see an October lull around here every year. Are leaves for quality forage? My plots are simply amazing why would deer want a leaf instead of a radish.
That was me that said maple leaves that are red seem preferred over the yellow maple leaves but they do eat both. And I've seen the best leaf eating of the large yellow poplar leaves. There's no doubt that poplar leaves is one of their favorite fall foods where I hunt.
Exactly how you pin point which individual trees they are keying in on is difficult. I can't say I know the answer but I do know that for a 3 week period when leaves are falling, deer spend a lot of time feeding on a wide variety of leaf species.
And I think they prefer fallen leaves over ones that are still on the tree. There is something about the upper leaves of mature trees that must taste better than the ones growing at ground level. The same thing with browse... My deer don't browse the ground level twigs of hickory, but when I cut a mature hickory for firewood, they hammer every bud on every branch when the tree is down on the ground. Must be a chemical change in mature growth that makes it taste better.
I think it's one more ingredient of the "lull". IMO, Food near beds, deer's awareness of hunting pressure, and winter coats while it's still warm all contribute to a drop in deer daytime deer sightings during the middle of October.
