During a hike near the James River, I came across a group of Forster’s Terns flying above a stream. I watched as they floated, effortlessly in the air above the water. After a few seconds they would dive out of view and then come flying back up, circle around, and start over. I assume they were catching small fish but I couldn’t get close enough to be sure. The tern pictured here is hovering in position, waiting to dive.
