16 compartment purple martin house designed to fit around a pole. Sides swing down like a writing desk to allow for cleaning and inspection. All compartments are vented into a central chamber which connects to the attic for thorough ventilation. All ventilation holes are screened to keep insects out. Design still needs drainage, and probably a means of accessing the attic to clean out anything that manages to find a way in.
I created this model from looking at the pictures on the linked site. If you're interested in plans, click the thumbnail to go to Chuck Abare's site. #birds #nestbox #purple_martins
