From Stokes Field Guide to Birds-Western Region & Kaufman Focus Guide-Birds of North America:
HABITAT/BEHAVIOR: Very common and widespread; the most numerous of medium-sized gulls in most areas. Gathers on beaches, ponds, rivers; large flocks rest in parking lots.
IDENTIFYING MARKS: 19"; Summer: Pale gray mantle; dark ring just before tip of thin yellow bill; yellow legs; yellow eye. Winter: Like summer, but light brown spotting on crown and nape. Gulls outside a fast food restaurant are almost always Ring-billed Gulls; they seem to have found a niche.
