An adult in breeding plumage. Medium size tern, slightly smaller than Elegant and Sandwich terns with heavy black bill and relatively long black legs. It’s plumage is pale silvery gray and white with an entirely black crown. In flight I could notice a notched tail and dusky tips to the primaries. It was on the beach a bit apart from a huge mixed flock of Franklin’s and Gray Gulls.
