At first glance I thought the gull feeding offshore was a Bonaparte’s Gull, but after taking a second look, I believe this is a Black-headed Gull in non-breeding plumage. The black-tipped red bill is the surest way to id when on the water, along with his cute little red legs and feet.

Common throughout Eurasia, they are rarer on this side of the Atlantic; the first sighting north of Mexico was recorded in 1930 in Newburyport. When Black-headed Gulls are spotted in the US, they are most likely seen along the Massachusetts coastline.
