This small gull has a slender bill, a rounded head, and a dark eye. Breeding adults have a white head and black wingtips with white spots. Nonbreeding adults have pale brown mottling on the head and neck, while juveniles are brownish overall.
It uses lakes, rivers, and shorelines. Fish, crustaceans, shellfish, and insects are among its foods; in fields it also takes insects and grain. Its feeding varies with habitat and season.
