Remarkable; very rare here; First observed by Bill Gette and birding group earlier in the day; flock on the ocean 3/4 to 1 mile off Lot 6; 12 adults, 2 -1W; although distant, it was apparent that these were not Mute Swans; with some difficulty the heavy all black bills (lacking knobs) of the adults could be discerned, along with the comparatively short and straighter necks; the two juveniles showed characteristic all pale pinking bills (can be seen in at least one photo) and more tan less dark plumage than young Mutes. Of interest, there is a record of 17 from Plum Island sixty-one years ago, on 20 November 1958 (Stanwood, Knight; Birds of Massachusetts by Veit & Petersen, 1993)
