I used to hang out with the seagulls on Hampton Beach NH years ago. I’d go very early in the morning when very few people were on the beach with a sack of sunflower seeds. I’d sit in my beach chair and flick those seeds into the air one at a time. Eventually I’d collect a crowd of them and they would take to grabbing the seeds as they were still in mid-air. Those seagulls are pretty good at catching things up in the air.
The State of Texas said years ago that we could no longer throw firecracks up in the air for the gulls to catch.
