Bird Watching?

On a Saturday bird watching trip last weekend it was a good thing that Uncle Andy also looked down
every once in a while and paid attention to other sounds around him.  He said he heard a sound in some brush and slowed down when he heard it again.  He said he could smell skunk odor so he wasn't surprised when a skunk crossed the path in front of him.  The skunk stopped, looked at him, and then continued across the trail.  Whew!  No Phew!
