Adult gulls are mainly gray or white, with variable head markings. In the breeding season, the head is either pure white, black, gray, or brown; it becomes streaked or smudgy in winter. The bill is strong and slightly hooked and in some species shows a spot of color. Bill and leg colors help to distinguish species, as do wing patterns. Adaptable opportunists, gulls feed on insects, mollusks, and crustaceans on beaches; worms and grubs in plowed fields; fish along shores; and garbage from ships. Some of the larger gulls prey on the eggs and the young of other birds, including their own kind.
