Nest Box Sizes

Building your own nest box can be a fun family project.  Almost any type of lumbar can be used, as long as it is untreated. A good choice is cedar or fur, both of which weather well.

Visit the bluebird section for video instructions on building a bluebird box.  The same basic steps can be used to build larger boxes.  

Each species shows has a favored box and hole size.  Do not be too concerned, however, if your next box is not perfect.  The birds do not use rulers and natural cavities are not perfect sizes.
