Birds Choice Recycled Ultimate Bluebird House Bird Houses

Perhaps the most deluxe, functional and bird-friendly house on the market today.  It is approved by the North American Bluebird Society. Side panels enable clear view of the nest through a clear plexy glass that holds the nest secure.  The other panel door opens for easy cleaning.  The raised screen on the bottom of the house protects the nest from blowfly infestation. If blowflys get into the nest, they will drop to the floor of the bird house and not be able to get back to the nest. 1-1/2″” Entrance hole includes predator guard and copper portal.
