This appears to be a fledgling flight school being held at the Heritage Duck Pond.  These little guys were inching close to the ledge then were flying down to the water.  The rookies were looking on as if to say "Oh, so that's how you do it".  We start our lives with no knowledge of how the world works and we depend on the experience of others to survive.  Our parents, school teachers, college professors, and on the job trainers provide education at a metered rated to ensure we can absorb the information.  Our whole lives are a constant learning session that happens whether we are paying attention or not.  Can you imagine the exhilaration a bird must feel the first time it takes flight?
