Architectural Birdhouses by Home Bazaar, Inc. Beautiful houses and feeders great for actual use, yard art, interior decor, or as great gifts for new homeowners. Plenty of windows, a pine shingled roof and a high pitched roofline highlight this style. A removable back wall, drainage, ventilation, an unpainted interior and a 1 and a quarter inch hole size will invite nesting birds in and keep larger ones out. House can be hung with mounting peg included.
