This practical guide explains how to build and maintain nesting boxes for common native birds, describing which species readily use artificial homes and the design features that attract them. It covers suitable materials, exterior finishes, precise box dimensions, placement and mounting, feeding devices, and seasonal care, and includes detailed plates and drawings of proven house types for bluebirds, robins, wrens, woodpeckers, nuthatches, swallows, titmice, and chickadees.
