Because I lived on The Fort for six years, I’ve seen a few gulls in my day. Depending on the species, gulls have up to four plumage types as they mature, plus they change from breeding plumage to winter plumage as adults.
This causes many people to throw up their hands is discuss when trying to identify the birds they are seeing. I even get comments from seasoned birders and twitchers that they get confused. With this in mind, I have posted many gull tips over the past few years in hopes that it will help those of us on Cape Ann and also the many, many birders that come here in the winter to find them. Gloucester has some pretty cool birds here in the winter that many inlanders just don’t get to see.
I hope that this information is helpful!
