The Rustic Roof Bluebird House is a uniquely styled house with a natural bark roof that comes fully assembled and ready to mount. It contains a front hinged panel which makes annual cleaning a breeze. This house also features an air vent to allow for proper air circulation throughout the birdhouse and two internal drain holes to keep the nest dry. The slanted roof prevents predators from waiting on top of the bluebird house and a pre-drilled hole will allow you to mount to most surfaces. Measuring 6 x 5.75 x 11 inches high, bluebirds will want to move right in.
