What got into the oak tree?

When I saw that something had been in the only oak tree that had acorns left on it, I went to check my critter cam. All that was on it was javelina. Not enough damage for it to have been a bear. Just broken twigs and leaves littered on the ground. Maybe a fox or ringtail.

The javelina don't seem to mind walking on a bed of nails at all. Figures!
