Try This: Wood Birdhouse

Build it and they will come.

The little red birdhouse was made from a length of old deck railing. The gray house uses a length of barn siding. Look for sound wood that doesn’t contain too many cracks and that has paint or stain on just one side so the house’s interior will be untreated. You’ll need about a 3-foot length, with a width of 6 to 8 inches.
