But as I've learned, simply finding an oak dropping acorns is not enough. The nuts have to be palatable to deer, which explains the many times I've found the ground littered with acorns under a sprawling oak with no evidence of deer sign nearby. Usually the explanation is that the acorns are wormy (and therefore bitter) and the surest way to make this determination is to check if the dropped acorns are wearing caps. Capped acorns are almost always wormy and deer will shun them. Acorns without caps are usually healthy and will be devoured by whitetails. On a scouting trip yesterday I found a huge red oak dropping capped acorns, so I cut one open, discovered the worm, and shot the photo above. Since I learned this a few years back from a professional logger, I've learned not to waste a lot of time scouting or hunting near such a tree in the early season. I simply keep scouting until I find the right oak, and the abundance of deer sign that indicates whitetails are hitting this spot.
