Ernes are fish-catching eagles of the genus Haliaeetus. They are large birds of prey that inhabit coastal regions and feed mainly on fish, which they catch by swooping down from the air and snatching them from the water's surface. They have long, broad wings and a hooked beak, and their plumage is usually dark brown or black. Ernes are found in many parts of the world, including North America, Europe, Asia, and Africa.
