About the Ring-billed Gull

The Ring-billed Gull is the gull Michiganders actually see — the parking-lot gull, the beach-blanket gull, the one wheeling behind ferries and mall food courts alike. Adults are trim and clean: pale gray back, white body, yellow legs, and the neat black ring around the bill that names them. Full adult plumage takes three years, so flocks are a study in mottled brown adolescence.

Ring-bills nest in raucous colonies on Great Lakes islands and breakwaters, sometimes tens of thousands of pairs strong. Hammered by egging and plume hunting a century ago, they rebounded into arguably the most abundant gull on the continent — a bird that took everything the modern world changed and made it habitat.

Anything, arranged attractively: fish, insects (they hawk flying ants in midair), earthworms behind plows, and the entire human snack canon. Natural foraging still dominates away from people.

Questions birders ask

Are "seagulls" all the same bird?

No — Michigan hosts several gull species, and "seagull" isn't one of them. Your parking-lot bird is almost always a Ring-billed; the bigger, pink-legged one on the pier is likely a Herring Gull.

Why are gulls so far from water, in mall parking lots?

Ring-bills are generalists that treat lots as safe, open loafing ground with food potential. They commute — many roost on water at night and work inland fields and lots by day.

Why do gulls stamp their feet on wet grass?

The pattering imitates rain and draws earthworms to the surface — a neat trick called "foot paddling." Watch a ballfield after irrigation and you'll see the whole flock dancing.

Can I see Ring-billed Gulls in Michigan in winter?

Yes, in any month. Numbers stay fairly steady from month to month. Winter is often the easiest time to find them, with bare branches, open sightlines, and snow cover concentrating birds at reliable food.

How long does a Ring-billed Gull take to reach adult plumage?

Three years. First-year birds are mottled brown and gray with a pink black-tipped bill and a dark tail band, and the crisp gray back and neat black bill ring arrive in the third year.

What is a group of gulls called?

A colony at the nest site and a flock everywhere else. Ring-billed Gulls nest in dense Great Lakes island colonies numbering in the thousands and disperse to parking lots, beaches, and farm fields the rest of the year.
