If you are an confident woodworker with some building experience, you may even feel comfortable designing your own bird house with the information you've learned about what nesting birds want. If you are a novice, however, building a bird house from scratch may seem too intimidating or ambitious, even with detailed plans. In that case, you may want to consider using a bird house kit with pre_cut pieces to assemble. Another option is to start with a simple bird house and make modifications to the design to make it more bird_friendly to suit the species you hope will take up residence.
Build a box that will stay dry and warm. Place the roof of a birdhouse at a slight angle and extend it over the sides and front of the box. In this way, the roof will shed rain or snow and protect the entrance hole and sides from dripping water. Drill four, 1ǚ_inch holes in the floor to provide drainage if water seeps in. The sides of a nest box should extend down beyond the floor so water won't leak in.
