Is there only one area of the tree they are bothering - there is probably either a food source there (insects, ants, etc.) or they are stashing acorns there (or retrieving ones they already stashed there)>
Unless they are actively drilling the tree, they are probably not harming it... If they are retrieving food already stored there, then the holes are already there. If they are eating ants or what not, again they are probably not hurting anything...
