Gulls mean more than humans now. Lovely...
Sea gulls are predators. These birds can strike savagely and have strong beaks. Coming at you in a full drive they have the weight to damage you severely. You are lucky if you aren't cut up on the head, face, ears or eyes. I rescued a wounded gull one time that a hunter had deliberately wounded when I was in the border Patrol. The $%#^% thing nearly took out my eye.
Finally clamped down on my finger with its vise of a beak and held on while we took it to an animal shelter. Never again.
