Black-headed gull (Larus ridibundus).

This gull is 38–44 cm (15–17 in) long with a 94–105 cm (37–41 in) wingspan. The summer adult has a chocolate-brown head (not black, although does look black from a distance), pale grey body, black tips to the primary wing feathers and a red bill and legs. The hood is lost in winter leaving just 2 dark spots. Immature birds have a mottled pattern of brown spots over most of the body. It breeds in colonies in large reed beds or marshes, or on islands in lakes, nesting on the ground. Like most gulls it is highly gregarious in winter both when feeding or in evening roosts. The black-headed gull is a bold and opportunistic feeder. It eats insects, fish, seeds, worms, scraps and carrion in towns or invertebrates in ploughed fields with equal relish. It is a noisy species, especially in colonies, with a familiar "kree-ar" call. Its scientific name means laughing gull. It can be found over much of Europe except Spain, Italy and Greece. It is also found in Japan and Eastern China. It is an occasional visitor to the east coast of North America.
