gullS and Allies
Gulls, terns, skimmers, skuas, puffins, and their allies belong to the order Charadriiformes. Charadriiformes is a diverse order and contains many other families. Most live near water and eat invertebrates or other small animals, however, some are pelagic (seabirds), some occupy deserts and a few are found in thick forest.
Gulls
Order Charadriiformes Family Laridae
Gulls are most closely related to the terns, noddies, and skimmers. All of this group, except the terns, probably have ultraviolet vision as they have the SWS1 opsin gene. Gulls are typically medium to large birds, usually grey or white, often with black markings on the head or wings. They typically have harsh wailing or squawking calls, stout, longish bills, and webbed feet. gull species range in size from 29 to 76 cm. Most gulls, particularly Larus species, are ground nesting carnivores, which will take live food or scavenge opportunistically. Live food often includes crabs and small fish. gulls have unhinging jaws which allow them to consume large prey. Apart from the kittiwakes, gulls are typically coastal or inland species, rarely venturing far out to sea. large species take up to four years to attain full adult plumage, but two years is typical for small gulls. gulls are resourceful, inquisitive and intelligent birds, demonstrating complex methods of communication and a highly developed social structure.
