Songbird Essentials Ultimate Bluebird House

B rass hinged doors on both sides with Plexiglas on one side to monitor the nest without the danger of chicks falling out. Predator protector of solid copper to eliminate squirrels and woodpeckers from enlarging the entrance hole. Elevated mesh floor to help protect the young chicks from Blowflies. Zinc Chromate plated screws that provide a more sturdy, longer lasting house than one assembled with nails. The screws will not “bleed” leaving unattractive stains below. Made of long lasting Cedar.
