This cute house is perfect for titmouses and nuthatches. Both birds like 1 1/4 inch holes and their entrance high off the floor. The unfinished reclaimed wood is thick for good insulation from the old New England mills or salvaged barns. The roof is scrap cedar. Each house is designed so the bottom can be easily removed with 2 screws for annual cleaning. Made by a local crafter exclusively for Real Green Goods. 13" tall x 4" wide x 4 1/2" deep.
