This pretty house will get you either a Black-capped Chickadee or a House Wren (it will NOT get a Carolina Wren with a white eye stripe. They require a 1 and 1/2 inch bluebird size hole).  The side opens for easy cleaning, has good ventilation and drainage, and comes with two brass screws and predrilled holes.  A cute chickadee is etched on the front.  Don’t be fooled by the tag on the side that says Wren Box.  The hole is 1 and 1/8 inches, suitable for a chickadee or house wren.  English sparrows cannot get into this.
