Helpful Tips

  • Add a thin layer of wood shavings to the box.
  • Flammulated Owls can compete with other cavity-nesting birds for nest sites. You can add more nest boxes for other species to help reduce competition.
  • Natural cavities are preferred to nest boxes, but nest boxes can increase nesting opportunities where natural cavities are lacking.
  • Position boxes so that vegetation does not block the area in front of the entrance hole.
