Our bluebirds were using their box for months then abruptly abandoned it. To our knowledge there were no eggs or babies after months of nesting. I took out the nest and placed it around pine trees and cleaned out the box. Is it safe to put the nest back in the cleaned out box? - White Hall, MDpredator will be able to reach in and nab eggs/nestlings that are closer to the entrance hole.
If you are sure your bluebirds have fledged or it is the end of the season (the beginning of September), it is OK to remove the nest and clean out the box completely.
If the birds started or even completed a nest and then left it for some reason, like yours did, the nest material can be left in the box for the season.
When two potential nesting sites are near each other, sometimes a Tree Swallow or Bluebird will build a partial or complete nest because they can't decide which box to use or it may be to deter other birds from nesting nearby. However, sometimes this nest is used for a second brood.
