I ran over my driveway light aluminum pole and fixed it by covering it with cedar. A downy wood pecker decided it was a dead tree and literally drilled it full of big holes.
It is comical to hear it. BrrrrrTTTT Brrrttt DING, Ding Ding
They really are entertaining birds. One can only wonder why they peck on metal so much except to hear the noise. I can imagine that a cedar covered metal pole provides them and you with a lot of enjoyment.
