The main experience I have with gulls is one by one eating up all the ducklings in the canal here in Amsterdam, to the horror of everyone on the terraces.

Neither. Seagulls are natural born opportunists. If they can grab your hamburger or hunt and eat a pigeon – they'll do that. Just the same for landfills or farms.
