There are varying factors that affect when and why particular hardwood species and particular trees within a species drop their leaves. Generally, speaking oaks drop their leaves later than most others. That being said, most of the leaves in your picture are oaks. Red oaks have pointed tips on their lobes or serrated edges while White oaks have rounded tipped lobes or serrated edges.

Without a close examination or FBI type investigation it looks like there is a Post oak nearby based upon many leaves in this mixture. Post oak has a cross look to them and one leaf right in the middle of the picture is a good example. Post oak is one of the less abundant Oaks found in the Great Wooded South and in my opinion is one of the most beautiful yard trees. It's limbs have very little to no weeping effect and in fact, most usually will have a slight upturn toward the ends of lower limbs. They are most always found in locations with shallow soils and a dry environment.
