Bluebirds are some of the most desirable yard and garden guests of any North American bird species. They are wonderfully colorful warbling insectivorous songbirds that add an aura of grace and charm to most any yard or garden. Enjoy the serenades of your friendly bluebird guests all season long with the Woodlink Bluebird House Bird House. It is specifically designed to attract and house bluebirds. It features a perfectly designed entrance hole that discourages the intrusion of other species, an easy to open front panel for easy cleaning, a half inch ventilation gap at the top and a drainage hole at the base. The front even slides down so you can check on your nesting bluebirds without disturbing them.
