Abstract
A nest box or birdhouse wherein a removable roof panel provides easy physical access to a nest cavity and also secures an interchangeable entrance panel in multiple positions—for both active-breeding-season use and off-season storage. All vertical enclosure components can remain in place during activity monitoring, avoiding harm to eggs or hatchlings when the nest box is opened. In the off-season-storage configuration, the enclosed nest cavity is eliminated to prevent infestation. The nest box utilizes a hollow roof-locking pin for increased ventilation. Furthermore, an adjustable-height mounting mechanism helps prevent predator attacks and allows the nest box to be accessed at safe heights during physical monitoring and maintenance.
