Caspian Tern

Sterna maxima - Rather common both coastally and inland. The Caspian Tern resembles the Royal, but can always be told by its blood-red bill and its loud raucous call. The wider wings give it a more gull-like appearance than most terns, and its behavior also is more gull-like. It alights on the water, occasionally soars, robs other seabirds, and eats eggs. Fish are its chief diet. Call is a loud harsh kraaa.
