Larus canus

Adult common gulls are 16–18 in long, noticeably smaller than the herring gull and slightly smaller than the ring-billed gull. It is further distinguished from the ring-billed gull by its shorter, more tapered bill, which is a more greenish shade of yellow and is unmarked during the breeding season. The body is grey above and white below. The legs are yellow in the breeding season, becoming duller in the winter. In winter, the head is streaked grey and the bill often has a poorly defined blackish band near the tip, which is sometimes sufficiently obvious to cause confusion with ring-billed gull. They have black wingtips with large white "mirrors" on the outer primaries p9 and p10, which are smaller than those in the short-billed gull. Young birds have scaly black-brown upperparts and a neat wing pattern, and pink legs which become greyish in the second year before turning yellow. By the first winter, the head and belly are white, with fine streaks and greyish feathers growing on the saddle. They take three years (up to four in the Kamchatka subspecies) to reach maturity. The call is a high-pitched "laughing" cry.
