I have them in my yard a lot. The funny thing is they bang away at the metal roof and drains on my garage almost as much as on the trees. I guess they must like the sound.
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
Maybe they are heavy metal flickers,,they are gorgeous.
