Identification - It is slightly larger than a crow. The breeding adults have a yellow bill with a distinct black ring, a slate-gray back with contrasting snow-white underparts, black wingtips with white "mirrors", and yellow-green legs. Sexes are similar in appearance.
Morsels - This "seagull" is more at home following farm plows in the interior than feeding along marine shores. The Ring-billed Gull, originally a bird of the prairies, has successfully followed human settlement to greatly expand its range. Evidence suggests that gulls rely on their memory of topographic features in the landscape to find their way back to breeding colonies or wintering areas.
