There is a small marine biological reserve right across from us. We get to watch it drain and fill each day with the tides. There are families of Caspian terns and Elegant terns that live on the shore. The young birds are big enough to fly, but still the parents feed them. The youngsters fly out to meet the adults and coach them back to the right place to land and hand over the fish they just brought back. You can tell which kind of tern it is by the tone of the conversation. Elegants are a little lighter; Caspians a little heavier.
