The woodpecker make the holes to hide the acorns for winter season and squirrels take the acorns out to eat them. They fight a lot with the woodpeckers for the acorns.
It is a kind of pine. The woodpeckers make the holes and the squirrels store their nuts there for the winter.
Thank you! I thought it was growing from the trunk by itself. I was shocked. Somehow it looks disgusting and cool at the same time.
