You are looking for a very colorful birdhouse. This is the first birdhouse in a series of four that you must find to open the large cache at exit 32, Bird Houses of Cook County Travel Bug Nesting Box.
This trail is along Hwy 41 between Adel and Cecil. They run south just outside of Adel towards Cecil. There is safe parking/pull off areas close to each birdhouse. Interstate travelers can get off at Exit 37 and head east to Hwy 41, turn South on Hwy 41 towards Cecil and the final cache is located off of Exit 32.
In order to unlock the Nesting Box, you must write down the number on the bottom of each birdhouse along the trail. The number on the bottom of this birdhouse will be the first number in the combination of the lock.
Each birdhouse along the route will have a log to sign (BYOP). Please do do attempt to remove the log container from the birdhouse, it is glued in place. Simply unscrew the cap and remove the bag with the log. Please replace the log and screw the cap back on securely, but do not over tighten. The birdhouses are very delicate also, so please use a soft touch when handling them.
***CONGRATS to Gadawgcacher on the FTF!***
I hope you enjoy the series and Cache On!
