The Caspian Tern is the largest Tern in the world. The large red-orange bill is quite distinctive. Caspian Terns breed around lakes and coasts in North America, Europe, and Asia and migrate south to Central America, northernmost South America, southern Asia and Africa. Year-round residents occur on the coasts of Africa, southern Asia, and Australia.

They are mostly fish eaters and dive for them. We see them frequently in the Bay Area. My favorite place is Middle Harbor, Oakland, CA in August-October.
