They can tap all day. Our former house had cedar siding. They thought it was a tree. They loved to pound their acorns into the edge trim. They just shredded it. Consultants said we could put these long spiky lethal looking things on the edge. I could just envision impaled birds. What stopped? Paint. We hated to paint the cedar, but when we painted, the woodpeckers went back to the oak trees and no birds were damaged.
