Gull research also continues on the island and looks into topics like nesting area and density movement over generations. The island is home to various species including Herring Gulls, Lesser black-backed, and Greater black-backed gulls. Social dynamics among the gulls and chicks are also studied to look into group defensive strategies employed by the birds. Gull eggs and chicks blend into the beach rocks due to their speckled camouflage. After hatching, the young are reliant upon their parents for food and protection from other gulls. Gulls are quite territorial, especially during the chick season, and would attack any young that encroach upon their self-proclaimed territory. These birds receive a poor reputation from beachgoers due to their opportunistic feeding behaviors, though many sandwich thieves are laughing gulls. In actuality, these birds display just as many beautiful habits and examples of raw nature as any other species. They may lack gaudy coloring or a particularly beautiful bird song, but they are most certainly an exemplary account of evolutionary strength.
