The Herring Gull, Larus argentatus, is a large gull (up to 26 inches or 66 cm long), and is the most abundant and best known of all gulls along the shores of Asia, western Europe, and North America.[1] It breeds across North America, Europe and Asia. Some Herring Gulls, especially those resident in colder areas, migrate further south in winter, but many are permanent residents, e.g. those on the lower Great Lakes, on the east coast of North America or at the North Sea shores. Herring Gulls are also abundant around inland garbage dumps, and some have even adapted to life in inland cities. The Great Black-backed Gull, Larus marinus, is a very large gull which breeds on the European and North American coasts and islands of the North Atlantic. It is fairly sedentary, but some Great Black-backed Gulls move further south or inland to large lakes or reservoirs.This is the largest gull, much bigger than a Herring Gull and is often described as the King of Gulls. It is 61–74 cm (24–28 in) long with a 1.4–1.7 m (4 ft 7 in – 5 ft 7 in) wingspan, the large adult males often weighing in at more than 2 kilogrammes (4 lb 6 oz). It is bulky, and has a powerful bill. The adults have black wings and back, with conspicuous white "mirrors" at the wing tips. The legs are pinkish, and the bill yellow with a red spot.
