A Fox Squirrel feeding on acorns dropped by Live Oak trees in a suburban neighborhood.
Wikipedia has this to say about Fox Squirrels:
In eastern Texas, eastern fox squirrels prefer the acorns of bluejack oak, southern red oak (Q. falcata), and overcup oak (Q. lyrata). The least preferred foods are acorns of swamp chestnut oak (Q. michauxii) and overcup oak. In California, eastern fox squirrels feed on English walnuts (J. regia), oranges, avocados, strawberries, and tomatoes. In midwinter, they feed on eucalyptus seeds.
