This is a beautifully constructed, Wren Bird House. Made from the finest materials of Red Cedar wood, stainless fasteners, and brass hinges. The hinged roof makes for easy opening to view eggs or a developing brood, along with easy access for clean out. An important feature of this meticulously crafted abode is the 1" Portal Guard. This copper coated entrance guard allows for only small species birds such as Wrens to gain access, while denying entry to larger predator-type birds. For best results to attract, mount box in a tree at about a six foot height toward the outward end of a sturdy branch. Mounting device included.
