How often should bluebird boxes be inspected?
Under normal circumstances, a weekly inspection is sufficient. However other factors may require more frequent monitoring. During the egg laying period, which generally takes place in the early morning and lasts 5 days, care should be taken so as not to frighten the female. Boxes should not be opened after the nestlings are 12 to 13 days old. This may frighten them and cause the young to fledged prematurely. After the 13th day, it is best to observe the box at a distance until you are certain all the nestlings have fledged.
