I am going to give it a shot with Wood ducks. I don't expect success due to the setting being rather open, but what the heck? If it doesn't work out, I will re-purpose the house for small owls.
Speaking of which, has anyone tried composite decking materials for bird houses? Heavy as heck, but should be easy to clean and last longer than any of us. I saw in Running some pretty pricey bluebird houses made out of some really nice composite materials.
