Fish-eating fliers are birds that feed primarily on fish. Two examples of these birds are the Erne (5 letters) and the Tern (5 letters). The Erne is a large, heavy-bodied sea eagle found in Europe, Asia, and North America. It has a wingspan of up to 6 feet and feeds mainly on fish, which it catches by swooping down from the air. The Tern is a smaller bird, with a wingspan of up to 3 feet, and is found in many parts of the world. It feeds mainly on small fish, which it catches by diving into the water from the air. Both the Erne and the Tern are excellent fliers and are well adapted to catching fish in the air.
