A Gull is a fraction of the size of a Pelican but they can torment the big guys.
When a Brown Pelican surfaces after a dive they may have 2 gallons of water in their pouch along with a fish. They need to ‘spit out’ the salt water.
A Gull knows this. As soon as the Pelican opens his mouth…the Gull dives for the fish. And they get them too.
I can’t imagine what it would be like to stick my head in there!
