In the bird house business, there’s no such thing as “one size fits
all.” Decide which bird you want to attract, then get a house for that
particular bird. Look through any book or catalog and you’ll see bird
houses of all sizes and shapes, with perches and without, made of
materials you might not have thought of: recycled paper, gourds,
plastic, rubber, pottery, metal and concrete. The proper combination
of quality materials and design makes a good birdhouse.
