This Great Blue Heron was photographed a Upper Merion Park, King of Prussia, PA. The heron appeared at this park on a number of occasions. I had my nikon D3 with a 600mm f/4 VR lens with me that evening. The heron landed on the top of the tree. It stayed for about 30 minutes. I set up and used a Nikon SB-900 flash. I was able to catch this moment of take off.
