I would like to know why a woodpecker is making a circle of holes around my sugar maple trees and what can I do about it. Can this kill my trees?

Birding Expert - George H. Harrison

The woodpecker is probably a yellow-bellied sapsucker, and the ring of holes it has tapped around your sugar maple trees is to allow the sugar sap to flow out. The woodpecker will eat the sap and also the insects that are attracted to the sap. The holes will not hurt the trees. You should not do anything to keep the woodpecker from drilling the holes.
