During the 5 years I have had my owl boxes up, they have continuously been occupied by screech owls except for a 3 month span in one of the boxes when a tree squirrel took residence. The squirrel was eventually chased out by an owl.
These creatures are a constant source of delight and have helped to reduce my gopher population. Enjoy!

The 6-inch tall screech owls are one of my favorite birds of prey … tiny but very spunky! /Gary
