Detalhes da observação
Three together and later two with Sandwich and Royal Terns. All flying north over pier and following the surf line. Obviously smaller and not as pale as Sandwich Tern, and structurally different. In this plumage much of the black cap is retained, but the forehead area back to the eye is white. Critically this black is across the crown and unlike the Forster's Tern eye-mask. The mantle and upperwing were grayish, and showed a dark carpal bar and a dark trailing edge to the underside of the wing on the hand. The bill appeared all dark. Arctic eliminated due to structure (longer headed/necked look and more centered wing appearance, compared with short headed look and front-loaded appearance of arctic), flight style, and the lack of a pale secondary window. Photographed.
