Hey, I know about seagulls! They are the state bird in Utah, so they're dear to my heart. But they depicted them perfectly in FINDING NEMO...they scream MINE, MINE MINE...my great grandson used to delight in taking a loaf of old bread and tossing bits to them til they congregated in a mighty flock and then he'd run, lickety-split right through the middle of them just to see them fly up and into each other! Weird little kid.
