Rockland has a lot of gulls. Herring, Great Black-backed, and Ring-billed Gulls are numerous. A few Laughing Gulls are usually present. Bonaparte’s Gulls are found year-round, though they are much more common in spring and from mid-July through autumn. A few Common Black-headed Gulls turn up every year, as noted on Christmas Bird Counts. In winter, scan for Common and Red-throated Loons, Horned and Red-necked Grebes, Red-breasted Mergansers, Long-tailed Ducks, Buffleheads, Great Cormorants, Canada Geese, Mallards, and American Black Ducks. White-winged Scoters are the most commonly seen of the scoters. Greater Scaup occur irregularly.
