Helpful Tips

  • To avoid competition with House Sparrows, nest boxes should not be placed within a quarter mile of buildings. If House Sparrows become a problem, consider drilling a second entrance hole beside the first one (so that there are two separate but identical holes on the front panel) to enable bluebirds to better defend boxes from sparrows.
  • When placed along roadsides, boxes should face away from the road in order to avoid disturbance from vehicles.
  • Avoid placing nest boxes on utility poles, which can provide perches for potential predators, (e.g., American Kestrel).
