Friends, this green heron was alarmed by my presence, and i was alarmed when i got a closer look at this image, long after the bird had flown away, it was then that i noticed the feathers on the top of his head standing straight up on end.  Usually when i see this green heron, his head feathers are slicked back (like Elvis) and he is peacefully hunting the shoreline for aquatic food.  But when he discovered me, his feathers pointed the way and up he went.  Live and learn til Tomorrow MJ
