The term 'Cousin of the Gull' is a reference to the TERN, a seabird that is closely related to gulls. Terns are known for their long, pointed wings and forked tails, which help them to maneuver quickly in the air. They are found in many parts of the world, including coastal areas, islands, and inland wetlands. Terns feed mainly on small fish, but they also eat insects, crustaceans, and other small aquatic animals.
