Rustic Bluebird Houses in a variety of styles. Start a bluebird trail with one of our rustic bird houses. Choose from window nest boxes, open top birdhouses, small bluebird feeders, and horizontal bluebird houses. Be sure to place your bluebird houses 100 yards apart if starting a bluebird trail. If sparrows are a problem, you should place two bluebird houses back to back or up to 5 feet apart. This will keep the two species separate and at peace, while each bird species can create their own nesting homes.
