This morning saw the lowest tide of the year so far, a level of minus 2.1 feet. Large stretches of the southern and western sides of the North Basin lay exposed. All kinds of debris normally out of sight emerged into view. Relatively few birds took advantage of the offerings in the mud flats. Besides a few gulls, I saw a Snowy Egret, a Great Blue Heron, a Great Egret, two Mallards, and some American Crows. The only unusual visitors were two Caspian Terns, which I’ll feature tomorrow. A squad of Canada Geese flew overhead, as they do almost every day.
