Altre informazioni:
This is a noisy species, especially in colonies, with a familiar "kree-ar" call. Its scientific name means "laughing gull". It breeds in colonies in large reedbeds 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. It is not a pelagic species and is rarely seen at sea far from coasts. The Black-headed Gull is a bold and opportunist feeder and will eat insects, fish, seeds, worms, scraps and carrion in towns, or take invertebrates in ploughed fields with equal relish. This species takes two years to reach maturity. First-year birds have a black terminal tail band, more dark areas in the wings, and, in summer, a less fully developed dark hood. Like most gulls, Black-headed Gulls are long-lived birds, with a maximum age of 63 years recorded in the wild.
