I had read on Pinellasbirds.com that there were a few black terns on the Gandy bridge beach. It's fairly rare to see them in the Tampa bay area. They only come through here for a short time in the summer. Since I work close to the bridge, I stopped over there on my way home from work on one of the nights were it wasn't pouring down rain. There were large amounts of terns on the beach (when a dog wasn't chase them off the beach). I could only find a few black terns mixed in with other terns but I didn't see any that were in full black breeding color. Most of them were just changing feathers. I'm going to keep looking for that all black tern though.
I attached a short video of some terns bathing. I always like watching them swimming around in the water.
