Wikipedia has this to say about Fox Squirrels:
Food habits of eastern fox squirrels depend largely on geographic location. In general, eastern fox squirrel foods include mast, tree buds, insects, tubers, bulbs, roots, bird eggs, seeds of pines and spring-fruiting trees, and fungi. Agricultural crops such as corn, soybeans, oats, wheat, and fruit are also eaten. Mast eaten by eastern fox squirrels commonly includes turkey oak (Quercus laevis), southern red oak (Quercus falcata), blackjack oak (Quercus marilandica), bluejack oak (Quercus incana), post oak (Quercus stellata), and live oak (Quercus virginiana).
