I call this birdhouse the Arizona house, as it uses my no longer needed Arizona license plate, among other things.
We found an awesome metal scrapyard the other day. They had all these bins of old brass junk, much of which I have used on this house. It includes three different styles of drawer pulls, along with escutcheon plates, beauty rings, a key, a dog tag, and a plastic outlet cover.
My favorite part is the unusual top ornament. I just hope it doesn't act as a lightning rod.
