Around seven years ago, a friend of ours took an interest in Caleb's woodworking. Caleb used the measurements he was given along with the pamphlets about bluebirds and built bluebird nestboxes. He then placed the nestboxes all over our farm. We have had so many babies born here, that we lost count. This is one of this year's nests. If you search the blog, you can see other images of past year's babies.
