Both functional (those are mounted in trees and look solid and functional) and decorative. I imagine festooning a couple of trees with a variety of bright little dangling birdhouses. And should anyone decide to occupy one of the decorative birdhouses, that’s ok too. Some prefer style over function.
I have had a few kicking around that needed some repairs, and I finally got them out and repaired them and had a very creative hour painting on them that was glorious. I haven’t had my paints out in years.
Then I announced to HW that he could keep an eye out for cute birdhouses at thrift stores/in the garbage for me, even if they were beat up. “Oh, you want fixer-upper birdhouses?”
