Keep the entry hole on your existing wren house small with this Esschert Design Metal Hole Protector. This sturdy, square steel plate easily affixes to a wooden bird house, and its center, 1" diameter opening provides passage only to small songbirds. The galvanized steel handily prevents other birds from enlarging the entry, and a predrilled hole in each corner of the plate makes installation simple. Keep your chickadee or wren house protected from woodpeckers or squirrels with this Metal Hole Protector.
