Copper Bluebird House Portal


The Copper Bluebird House Portal looks great on any Bluebird House.  We call it our “$3.50 insurance policy” against damage by squirrels or woodpeckers.


Our Cedar Slot Style Bluebird Nesting Box goes over the entrance hole of your nesting box, and you will not have to worry about a woodpecker or squirrel chipping away at the hole and ruining the house.

Can also be used to repair a nesting box entrance hole that has been enlarged by squirrels, if not too damaged. Or, a Wood Bluebird House Predator Guard might be needed.
