GULLS (Family Laridae) are generalized foragers that utilize many kinds of food items ranging in size from insects to the carcasses of whales. They forage in the air, on foot in fields and the intertidal zone, and by swimming and diving for underwater prey. Although species and individual gulls may show considerable specialization in foraging techniques and food preferences, most species of gulls forage at least occasionally over a large range of available habitats and use a wide variety of feeding techniques.
