We found quite a few Common Terns at the Edwin B. Forsythe National Wildlife Refuge, Brigantine Division. They seem to work an area for food, then move on.  This one was hovering before diving into the water. I liked the head on angle of the Tern, with the wings in more of a vertical upright position, before it dove into the water. Usually they are so quick it is hard to get a shot, especially in focus.
