Birdhouses>Plow & Hearth Recycled Poly-Lumber Ultimate Bluebird House

Designed to be the most functional and bird-friendly bluebird house on the market today, this Ultimate Bluebird House is approved by the North American Bluebird Society and enjoyed by birds across the country! This unique bird house has a 1½” entry hole and provides protection from predators and blowflies. Built with recycled poly-lumber that is guaranteed to never crack, split, or fade. The two hinged sides of this clever bird house are labeled Clean and View. Opening the View side reveals a clear acrylic window through which you can monitor eggs and hatchlings with minimal disturbance. Open the Clean side to access the nesting area to clear away debris. The metal mesh nest cage keeps the nest elevated to help minimize blowfly infestations. The larvae fall through the mesh and can be swept away to keep them from the baby birds. Made in the USA.
