Owls & kestrels have been a welcome sight in many areas, as they diminish the pest population with their hunting abilities. They have suffered some habitat loss in the recent past, with the diminishing of forests and trees. Screech, barred, and barn owls easily accept manmade nest boxes for their homes, helping increase their population in your area. Screech owls, saw-whet owls, and kestrels require a 3" diameter hole, while larger barn owls and barred owls prefer a 6" diameter entrance. These homes can be post, wall, or pole mounted from 10' to 30' high for utmost success. Ensuring that a good food source is nearby helps with occupancy rates. Keeping the home away from a light source allows the owls to rest in the day. Place the home near the edge of a forest or along a field line to ensure these raptors find plenty of food.
