No bluebird nest box is sparrow proof. You can however discourage sparrows from nesting there. Avoid places next boxes close to barns, feedlots, and farmsteads. These provide plenty off cover for sparrows. Sparrows may not like nest boxes made of PVC pipe because the interior is circle. They also dislike slot boxes.

No they build a new nest for each brood. However they may use the same nest site year after year.
You can protect it by giving it a place to nest and protecting it from sparrows who will harass it.
