Gulls are typically called as Seagulls. These are medium to large birds, usually grey or white, often with black markings on the head or wings. They typically have harsh wailing or squawking calls, stout, longish bills, and webbed feet. Gull species range in size from the Little Gull [30 cm] to the Great Black-backed Gull [76 cm]. They are mostly migratory. These birds forage in flight OR pick up objects while swimming, walking OR wading. They also steal food from other birds and frequently scavenge. They are omnivorous; their diet may include insects, fish, grain, eggs, earthworms and rodents.
