Pelicans diving for fish is something to see for sure. You can sit and watch these birds for hours on end. To me, the resemble fighter jets flying in formation heading for the battle. This area of Florida is known for the manatee, but I have seen far more pelicans than manatees since relocating.
If you get the chance to visit Hutchinson Island, pull over and watch the pelicans for a bit, they never disappoint !
