    Many possible reasons, some natural and some not; if you have concern, consult a tree specialist.

    One possible explanation is that your tree is experiencing an infestation of calico scale, an insect that feeds on the sap of oak and many other trees and excretes honeydew, a sugary liquid that often drips from the branches of infected trees.  Infestations can be treated with introductions of predators and pesticides.
