This observation is for the Double-Breasted Cormorant. ...
(The Cormorant had caught fish, and a Gull was trying to steal its catch from it. I will make a separate observation for the Gull.) ...
Found alongside the pier, at Veterans Memorial Marina Park, in Safety Harbor, Florida.
I could not get close to this guy, it was very anti-photo! I think it was some kind of cormorant? It looks too fat to be Anhinga but I'm not super familiar with birds down here. It dived underwater a lot in this retention pond.
