When I took this shot it was as a reference, to look at the Night Herons in the image later.
Turns out there is a lot happening here. Best viewed large.
First, a Hammock is a small piece of land a few inches above water level. usually with short scrub trees, around here tall marsh grasses.
On the Hammock itself there are two Black-crowned Night Herons as well as a sleeping Egret.
All around the photograph, flying through the air, are Tree Swallows. Just a little sunshine and the insects quickly hatch.
Taken at Donnelley Wildlife Management Area, South Carolina.
