WoodLink Bluebird House is an ornithologically correct, traditional style birdhouse designed specifically for bluebirds. Crafted from durable, re-forested, kiln-dried inland red cedar, this house is both weather resistant and insect repelling, making it i for Eastern, Western, and Mountain Bluebirds. It is assembled with screws instead of nails to withstand temperature changes and ensure long-lasting durability. The house features a 1-1/2 inch entrance hole that is especially attractive to eastern Bluebirds. Its all-wood construction gives it a natural look that blends seamlessly into any yard. Built with a 5 inch by 5 inch base and a 1-1/2 inch hole centered 6 inches above the floor, the design corresponds with optimum bluebird dimensions. The easy-open front panel slides down for checking on nesting progress without disturbing the birds and allows for quick and easy cleaning. A 1/2 inch air ventilation gap at the top and a drain hole at the base provide proper airflow and moisture control. The specifically designed entrance holes discourage unwanted species from invading the nesting area. This birdhouse comes fully assembled and ready to mount. Model Number:
