Maritime birds are a group of seabirds that inhabit coastal areas and feed on fish, crustaceans, and other aquatic life. The most common of these birds is the Erne, which is a large, long-winged bird with a white head and neck, dark brown back, and white underparts. It is found in Europe, North Africa, and parts of Asia, and feeds mainly on fish. The Erne is an important species for conservation, as it is a key indicator of the health of coastal ecosystems.
