Helpful Tips

  • Position the nest box so that the entrance hole is facing east and towards open habitat.
  • To decrease competition from Tree Swallows, you can pair nest boxes about 15–20' apart, with pairs of houses about 300' from each other.
  • Clean out old nests as soon as a brood fledges so that the nest box can be used for a second nest attempt.
  • If House Sparrows are 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.
