Description : The Common Black-headed Gull is a medium-sized grey waterbird whose white head turns chocolate-brown in the summer (adult bird length approximately 43 cm, weight 300 g, wing 30 cm, bill 3.2 cm, tarsus 4.6 cm, tail 12 cm). It has narrow white crescent behind the eyes, and white tail and underparts. It feeds mainly on fish, prawns. It occasionally takes insects, garbage, slugs, earthworms, seeds and berries. It breeds in colonies, specifically in expansive reed beds, marshes, or on islands within lakes. During this period, it constructs its nests on the ground. In line with the behavior of most gull species, it exhibits a strong social inclination during the winter season, forming groups while feeding or congregating in evening roosts. However, the slender-billed gull is not adapted to pelagic environments and is seldom observed far from coastal areas, making sightings of this species at sea quite rare.
