California gull resting at seaside, it is a medium-sized gull, a bit larger than Ring-billed Gull and smaller than Herring Gull. Adults have medium-gray upperparts slightly darker than Herring Gull, and red and black markings on the bill. Takes four years for immatures to progress from mostly brown to fully white and gray adult plumage; intermediate plumages are often mottled and messy. Many immatures show a pink bill with a contrasting black tip, and dull pinkish or greenish-gray legs. Always note dark eye. Common and fairly widespread in western North America, inland and along the coast.
