First of all, Melanie at http://www.schoolgirlstyle.com has a wonderful owl themed classroom kit which you can purchase. Check out her colorful owl materials. They are beautiful!
Then, Ms. Durbin at http://3rdgradesahoot.blogspot.com.au/ has some fantastic owl ideas for the classroom, including this freebie Behavior Clip Chart available at her TpT store which I have already downloaded...and CANNOT wait to use next year!
Some of my favorite bulletin boards...
