Juvenile Herring Gull at Montrose Beach, one of three (click to see the larger version).

I had my first juvenile Herring Gulls (3) of the year on July 18. I usually start to see juvenile Herring Gulls about one month after the first juvenile Ring-billed Gulls show up, which is around the third week of June. There were also a couple of Semipalmated Sandpipers on the beach, a few Caspian Terns, including a whistling juvenile, and hundreds of dragonflies over the beach, dunes, and meadow.
