I finally got home to look at the photos of the terns and get a better identification. There were 2 Caspian Terns, 1 Black Tern already starting to lose its black coloring, and 1 Forster's Tern in winter coloring.
We also saw at least 12 juvenile White Ibis. All of them were in their brown coloring, we didn't see any adults.
Besides those birds we saw the usual cast of Great Egrets and Snowy Egrets, Great Blue Herons, Little Blue Herons, Green Herons. Plus other common birds.
