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 is only 5 inches deep but if sparrows still continue to be a problem, a wooden insert is included to reduce the depth even more. Sparrows rarely use the 3-1/2 inches depth, but bluebirds will still occupy it.
RANGE: Breeds east of the Rockies from southeastern Canada to Gulf of Mexico. Winters in southern part of breeding range and Mexico.
HABITAT: Enjoys open woodlands, fields and farmlands with scattered trees.
