Imagine our excitement when a Northern Saw-whet owl was discovered near our school property! When my Environmental Science class examined the beautiful creature closely, we saw that it had been banded as part of a U.S. Government program. We reported it, using the number indicated on its leg band, and are anxiously awaiting the information regarding where its journey began.
