Gilbertson Nest Box NABS Approved Eastern Bluebird House – PVC Birch Design with Cedar or Poly Roof

The Gold Standard for Eastern Bluebirds

Provide a safe, dry, and predator-resistant home for your backyard birds with the original Gilbertson Nest Box. Approved by the North American Bluebird Society (NABS), this birdhouse features a unique birch-style PVC body that outperforms traditional wood by resisting rot, cracks, and splits for years of reliable use.

Visual & Design Excellence

The attractive birch-texture finish blends seamlessly into natural landscapes while the specialized overhang roof protects residents from driving rain and discourages invasive house sparrows. Customize your look with either a rustic natural Cedar roof or a durable, eco-friendly matching Poly-lumber roof made from recycled plastic.

• Easy Monitoring: The innovative squeeze-body design allows you to easily remove the cavity for monitoring or cleaning without disturbing the mount.
• Superior Drainage: Recessed floors and a center drainage hole ensure the nest stays dry even during heavy storms.
• Pest Protection: Features a design that allows for easy attachment of wren guards or sparrow spookers.
• Simple Setup: Engineered specifically for quick mounting on standard 1/2-inch (OD) metal conduit.
