Plans for traditional wooden boxes are readily available. Does anyone have info on making a wood duck nesting box out of PVC? Seems like it would be pretty easy to do.
Last spring walking the dogs I saw a couple smallish birds up fairly high in a maple tree. Wondered what they were. Turned out to be a pair of wood ducks. I guess they were looking for a nesting hole. The tree was at least a quarter mile from any water.
