Dad called asking if I knew where he could buy a bluebird house so he could buy one for my mother for her birthday. I looked online real quick and discovered, to my amazement, that they sell these things for $60! What the crap? It's one board!
// Don't buy one. Just go to Home Depot and grab a 1"x6"x6' of pine and leave it on my front stoop. //
Each birdhouse was done entirely with hand tools and only took 50 minutes each. It's a race!
