I've been back to one of my favorite places to photograph birds recently -- Armand Bayou. They've rebuilt some of the boardwalks out onto the bayou. I was shooting egrets and herons when a few terns came through diving and feeding. I pulled the camera off the tripod and tried to get a few shots. This was the only one in focus. Not sure what variety of tern this is. If you know, please comment. The black spot on the eye throws me trying to ID this bird, not sure if it's a common or foster's tern or if the black spot is just part of molting. 400mm, 1/320 sec at f/4, handheld.
