Description : Slender-billed Gull bird’s length approximately 43 cm. It has sloping forhead, longish neck and longer bill compared with Black headed Gull. Adult has whish head allover year. It has deep red bill (often looking blackish, paler in winter). The slender-billed gull has a diverse diet, with approximately half of its food consisting of fish. It adopts a unique hunting technique by flying a few meters above the water's surface and diving into the water when it spots suitable prey. Additionally, it forages by probing the mud with its beak to feed on marine invertebrates and catches insects while in flight.
Unlike many other gull species, the slender-billed gull breeds in colonies, constructing nests on the ground. The nests are simple scrapes lightly lined with feathers and small bits of vegetation, where the female lays up to three white eggs with brown spots. Incubation of the eggs takes approximately 25 days, and the young gulls become capable of flight around 25 days after hatching.
During the winter season, the slender-billed gull exhibits gregarious behavior, gathering in groups both while feeding and during evening roosts. It typically stays close to land and is seldom observed far out at sea, as it is not adapted to pelagic (open ocean) environments.
