Gulls live and reproduce in coastal areas, though they can also be found farther inland near bodies of water. The two most common species of gulls found in North America, the herring and ring-billed gulls, have a wide distribution and live in farm fields, metropolitan areas, and the unsettled countryside. In urban areas, gulls will nest on rooftops, in or around landfills, and in parking lots, though they prefer to have access to standing water.
