Monday Mystery Answered

On Monday, I asked:

Where in the Celery Farm Natural Area are these next boxes located (tough question), and why are they located like that? And what's with the opening?

The answers are:

These boxes are located in the little-known Laino Wood section of the CF.

They are bluebird boxes, and I believe that Fred Weber placed them in pairs because House Sparrows will only occupy one of the boxes.

If House Sparrows do move in to one box, the other box can be used by Eastern Bluebirds.

Some bluebird boxes have narrow slits for openings to make them less attractive to ... you guessed it.... House Sparrows.
