What a fun experience to watch two Great Blue Herons tantalizing the Snow Geese at Middle Creek Wildlife Management Area.  I did a little research today and learned that most Great Blue Herons migrate south in Fall.  They are a hardy bird, however, and some will stay north in areas where the water is not frozen, thus they are listed as year-round residents in Pennsylvania.  Since we have had a mild winter (by Pennsylvania standards), these birds may have been here all season.  Every time they flew overhead, the Snow Geese would take off in a flurry of activity, only to settle back down on the water … until the Herons flew by again.  These are two of my most favorite birds in the same photo – the Great Blue Heron and the Snow Goose.
