It's standard practice, my class on my environmental degree went to see a composting site one time and we asked how they dealt with the gulls, did they bring in raptors? No, a guy with a shotgun, we were told, a flock of gulls will mob and kill any bird of prey

We tried relocating the nests and eggs to another site to see if that became their nesting place, but it didn't work. The piers of the naval base are clogged with mussels, an easy food source, and the roofs are safe from anything short of a Marine assault, so they kept coming back
