Woodpeckers walking on Tulip tree leaving it discolored. Will this damage the tree? Thanks.

I have 2 bird suet feeding stations mounted on a Tulip tree. The woodpeckers love it and have been on it every day for over a year. The tree has become discolored from where they walk everyday. It is dry and the tree bloomed fine. Will this hurt it in the long run? Photo below. Thanks.

Blonding of the tree bark from heavy bird activities is cosmetic.
