Boxes should be erected on a free-standing pole three to five feet above the ground – facing south, if possible – and facing a nearby tree or fence where young birds can safely land on their initial flights from the box. To reduce predation and competition from other species, no perch should be placed on the box; bluebirds do not need one. Boxes placed in pairs, about 20 feet apart, may help reduce competition from swallows.The Game Commission's Howard Nursery has been manufacturing bluebird nest boxes and box kits for more than a quarter century. Each year, about 9,000 boxes are manufactured there and sold or provided to Pennsylvanians to help bluebirds. That annual influx of new nest boxes helps ensure Pennsylvania remains a "keystone state" in bluebird conservation.
