I had woodpeckers bang on my siding next to the window to let me know the suet was bad for about 10 years.

It was steel siding at the time, and they left several nice dents.

As much as I’d love to keep feeding them, I had my siding replaced by insurance with vinyl (unrelated issue) and don’t really want holes all up it… so i weaned before it was replaced. Just attending their demands less frequently.

Hasn’t been an issue in the last year.
