What you're seeing here is a fascinating natural phenomenon. In late winter and early spring, as temperatures fluctuate, trees can start to "bleed" sap, especially from wounds or openings like the one in this tree. When the sap flows out and then hits freezing air, it can form these unique icicles. It's often called "sapsicles."
Trees draw water and nutrients from their roots up to their branches, a process known as sap flow. As the days get warmer and the nights remain cold, the internal pressure within the tree changes, pushing the sap out. Different trees produce different types of sap; for example, maple trees are well-known for their sweet sap, but many other deciduous trees will produce sap that can freeze this way. It's a sign that the tree is waking up from winter dormancy and preparing for new growth!
