Sparrow-Resistant Bluebird House
This Kentucky style, slot entrance bluebird house is designed to thwart sparrows. According to research at the University of Kentucky, bluebirds prefer a slot entrance to the standard circular hole - sparrows prefer the opposite. In addition, sparrows don't like a shallow box and bluebirds don't seem to mind. This box includes a wooden insert to reduce the depth to attract bluebirds while deterring sparrows.
