This close relative of the Ring-billed Gull has been recorded perhaps a couple dozen times in Massachusetts. Veit and Petersen in Birds of Massachusetts about 25 records, with most referring to the European subspecies (canus, Common Gull), but a few records of the ‘short-billed’ or American form from the western states (brachyrhynchus). Within the last decade, a few adults of the Siberian race (kamchatschens) have been observed along the east coast, including at least three convincing records from Massachusetts.

While the identification of adults is straightforward (at least to separate from Ring-billed Gull), separating first-winter birds among these two species can present a serious identification challenge.
