Our largest gull, this coastal species accompanies the ever-present Herring Gull at all times of the year, even during the summer, when they nest together in mixed colonies. However, the Black-backed always asserts dominance over its smaller relative. It preys on almost anything smaller than itself, including Dovekies, small ducks, petrels, fish, and shellfish, as well as the eggs and young of other gulls. Although found close to human habitations, it is a shyer bird than the Herring Gull.
