Wren house installed

This weekend I installed a wren house in the center of our front-yard orchard. Any idea why a wren house in particular?

Wrens are insectivores, they only eat insects. Good for me, and good for my orchard trees and shrubs.
AND
Wrens are very territorial. That means they don't like other (fruit-eating) birds in the neighborhood. This is also good for me, because I might have a chance of getting a cherry or a honeyberry.

I bought this cute house at the 2015 Wisconsin Garden Expo, and the "post" is from one of the cyprus trees that we had removed from the front yard before we installed the orchard.
