Thats wierd. But i do know pelicans can get pissed easily as a friend of mine found out on a dock in Fl. feeding some. He kept on feeding all of them accept this old torn up one and after awhile it took off only to circle back and dive bombed him in the head! It was the funnest thing I ever saw, it almost knocked him off the dock into the water LOL I think I remember pissing myself laughing so hard.
