I went out to Wild Birds Unlimited and bought a brand new replacement birdbox, one constructed of fine-grained cedar with a metal-clad roof. This one should last another 20 years. The old birdbox was nailed to a young cedar out in front. Maybe bumblebees will take it over again or maybe a family of wrens.
The old and the new.
A big hole in the side and smaller holes made by powder post beetles.
The new birdbox ready and waiting.
