Danny raises a number of good points. Seagulls should be by the water, not as far inland as Southgate or Melvindale where I've seen them. I've seen them too in Hamtramck where there's no body of water around. When I've been near the water, like at Elizabeth Park, I've seen them get aggressive with people for more food that fools were throwing them. These birds coming farther inland are a nuisance.
