There was a huge commotion going on far out in the bay. I could not tell what was happening. Pointed my camera in that direction & took several shots. Later on the computer I enlarged and saw that a cormorant had surfaced with a fish & the gulls mobbed the cormorant. They were trying to steal the fish. You can barely see the head of the cormorant on the surface with several gulls landing on it.
Juvenile Double-crested Cormorant (Phalacrocorax auritus)
Ring Billed Gulls (Larus delawarensis)
