Other owlers may suggest different advice. Theirs may be just as useful. One thing I have learned: No two screech owls are alike.
Here are Rules 5, 6, 7 and 8 of my Top 10 Rules forattracting Screech Owls -- with big-time advice from David Johnson of the Global Owl Project. (Thanks, David!)
More info follows.
Rule Five: The pole or tree should be at least 50 feet from your house. The Screech Owl needs a comfort zone.
Rule Six: The box should be in a generally shady place (not in the open sun), but somewhere where the opening gets morning or early afternoon sun.
Rule Seven: The box should be placed so that you can easily see the opening from your home.
Rule Eight: If possible, the box should be placed so that curious humans cannot readily see the opening.
