No clue what was going on here because the pelicans did not have any food that the gulls were after. The gulls were just in an excitable state that morning and were causing ruckus everywhere. These two briefly flew into the pelicans then went into the water. Managed to catch them just before they hit. The pelicans just ignored them.
