I suspect squirrels. They eat walnuts, pecans, hickories and acorns green. They also have been known to tear bark of branches and stems and to damages branches with leaves when making nests. Dr Tom Barnes wrote an article related to squirrels http://www2.ca.uky.edu/agcomm/pubs/for/for45/for45.htm
I have learned that if a bird feeder is close by those trees are more likely to suffer bark and nut damage

Professor, This was my first thought as I have had a running battle with squirrels, however some of these nuts remain on the tree limbs with the husk eaten. Is there a caterpillar or borer that could cause this damage? I have not seen any caterpillars on the trees although there was a hatching of them near and headed toward the trees that I intercepted and treated, Thank you for your assistance.

I would still suspect squirrels maybe birds but the tent to like softer fruit they can peck at. There is a Husk Fly but it's damage is not to peel the husk from the nut but more of eating the green shell of the husk see http://ipm.ucanr.edu/PMG/PESTNOTES/pn7430.html for more information.
