The Black-headed Gull (Scientific name: Chroicocephalus ridibundus) 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. (Wiki) Clicked at Muttrah Corniche, Muscat in Feb/2016.
