Seagull species range in size. Seagulls can drink either freshwater or saltwater, though they prefer freshwater. This suggests that long tail feathers in this species are very costly for the male to carry, and is purely a trick to impress females. The nest is a shallow scrape that lined with grass, sedge, or moss. Newborn chicks are covered in down and may leave the nest as soon as two days post-hatching, although they stay near the nest where the parents can protect them. Their wingspan can reach 57-63 inches (146-160 cm) in length. who was a leading ornithologist in the 1800s in America and Europe. Gulls can be found around the oceans worldwide with the exception of some central Pacific islands, and some areas in Southeast Asia. Their name is derived from its call which sounds like a shrill 'kittee-wa-aaake, kitte-wa-aaake'. The ivory gull is one of the most beautiful birds on Svalbard, with chalk-white plumage, black legs and yellowish bill. Ring-billed Gulls are omnivores (they will eat most anything); their diet includes fish and other marine creatures, small birds, eggs, rodents, earthworms, and in populated areas, refuse from dumps, trash cans, and restaurant parking lots. Bonaparte's Gulls reach maturity when they are two years old and prefer to nest in trees during mating season. They spend their winters at sea in the Northern Pacific Ocean, avoiding the ferocious storms that go across the Bering Sea. They range far inland from New Mexico to Manitoba. They will eat insects, fish, shellfish, and crabs. During the winter, the Iceland Gull concentrates at the Arctic sea ice openings which are created by ocean currents and warm upwellings (places the often nutrient-rich waters from the ocean depths rise to the surface attracting many fish) where they forage mostly at the water's surface, where the ice is slushy. The reward is mating. The smallest gull on the planet, the Little Gull is a very small sized gull that is roughly 11-12 inches (29-30 cm) in length with a 24 inch (61 cm) wingspan. They migrate south for the winter, and they are widely distributed in all oceans of the world. They often steal food from pelicans, terns, and other seagulls after they have made a catch. Mew Gulls build nests in conifers (they are the only white-headed gull that will build a nest in a tree), on islands in marshes (in vegetation), and on the ground. Herring and capelin are two extremely important fish species in the Barent’s sea eco system. The bill is yellow with no markings, and there is a small red ring going around the eyes. They are garbage men (sanitation engineers for the politically correct) with wings. Its coloring is very pale in all plumages, with no black in the wings or tail. The young are fed by both parents. These gulls usually nest in small colonies, although single nests have been sighted. They have a white head and body. They forage along the surface of the water, by either plunging or dipping into the water. This gull also has a yellow bill with a red spot near the tip of the lower mandible. When the mating is done, many birds bite these tail feathers off themselves. The newly hatched gulls do not fly away from the nest area until they are about 50 days old. During the summer breeding season, they gain a distinctive black neck ring, and their breast and belly takes on a pale pink tinge. The Glaucous Gull breeds in Alaska and northern Canada. The back and wings are gray; the wingtips are black with white spots. The Glaucous Gull has been seen to walk into bird colonies to steal eggs and chicks that have been left unprotected. These small gulls are best distinguished by their wedge-shaped tails and pigeon-like flight. Laughing Gulls breed in coastal marshes and ponds in large colonies. Breeding and nesting time frame for Herring Gulls is usually in May to June. To break open hard shells, they drop their catch, such as sea urchins and mollusks, onto the beach to break them open. Their head, neck, and under parts are white. Breeding and nesting time frame for Franklin's Gulls is usually in May to June. While the exact location and character of their wintering habitat is unknown, many Ross's Gulls have been seen to forage near pack ice in the winter. The head will often have a partial dark gray cap. Both parents will take turns feeding the young birds. The nest is usually lined with finer material, such as feathers and moss. When the gulls are nesting in wetlands, the nest is a depression in a grassy mound or loose gravel, and lined with grasses, sedges, moss, or leaves. The Heermann's Gull diet consists of small fish, crustaceans and mollusks. The Glaucous Gull is a large gull whose body will reach roughly 27 inches (68 cm) as an adult. The parents will aggressively defend their nests, often diving and swooping upon intruders. However, scientific studies have shown that the breeding success for the black-legged kittiwakes are much higher in years when capelin is the main prey compared to years when they feed mainly on herring. In the winter it migrates as far south as the Baja Peninsula of Mexico and all the way across to the Gulf of Mexico and Cuba. Seagulls may be seen as spiritual messengers and are often associated with the ability to see different viewpoints. A few pairs have been seen nesting in North America since the 1960s, and the species is now becoming more common on the East Coast and the Great Lakes. Learn more about wildlife on Svalbard Their nests are floating masses of rushes, cattails, and grasses built in shallow water and usually attached to emergent vegetation. The Little Gull feeds on small insects and insect larvae, crustaceans, mollusks, and small fish. The female gull normally lays 2 or 3 eggs. The Franklin's Gull (named after the Artic explorer Sir John Franklin) is a small gull that is roughly 13-14 inches (33-36cm) in length with a 35-41 inch (89-105 cm) wingspan. It is also breeds in the Great Lakes region, the Canadian Maritimes, and northern New England. Breeding and nesting time frame for Great Black-Backed Gulls is usually in May to June. In all actuality, there is no such thing as a seagull. The Western Gull prefers to breed on rocky islands near the coast from Southern Washington down to Baja California. The gulls are relatively uniform in shape but do vary in size and coloration. Their backs are grey, and their grey wings are tipped solid black. Seagulls are thought to be intelligent birds. They have a white head, neck and under parts with pale pink legs. The nest is typically a shallow depression on the ground lined with vegetation and feathers. The bill is yellow with a black ring near the tip (hence the name of the gull). It is a large bird (although smaller than a Glaucous Gull) whose body will reach roughly 20-23 inches (50-59 cm) as an adult. The bill is pale gray and tipped with yellow. They make the nest of sticks and grasses, and sometimes line them with feathers. Adults are roughly 16 inches (40 cm) in length with a wingspan of 35-40 inches (90-100 cm). Seagulls use strategy to figure out ways to steal food from other animals. Herring is feeding on young capelin and larvae, and those two species will therefore never be abundant at the same time. The sabine’s gull is the only European seagull with a forked tail. Their back and wings are a very dark gray to sooty black color. The neck and under parts are also white. The Lesser Black-Backed Gull is divided into several different subspecies that differ in the darkness of the back. It breeds in the Arctic and winters in the drift ice zone in the Antarctic about 17000 km one way. Additionally the pomarine skua (Stercorarius pomarinus) is quite common in the sea off Svalbard all summer, but doesn’t breed here. They will steal food from other birds and gulls and frequently scavenge. Most of the ivory gulls in Svalbard breed in colonies on inaccessible old nunataks (mountain peaks protruding through the glacier) on the inland. As for many of the waders, the arctic skua will also play hurt if a potential predator approaches the nest. Until 1972, it was considered a subspecies of the Herring Gull, but it is now classified as a full species. They like to feed in flocks and catch their food at the surface of the water. Seagull has strong body, longish bills, elongated legs and webbed feet. The black-legged kittiwake has a life expectancy of about 13 years. These predators have been known to kill all the young in a colony. Seagull is a type of sea bird. Seagulls often return to the same colony every year. Red-legged Kittiwakes are one of the few species of gulls that are not scavengers. The chicks leave the nest about 48 hours after hatching. Nearly 10,000 breeding pairs nest on Svalbard, usually in open colonies along the west and north coasts. In Svalbard, there are no birds of prey. They only have one brood per year. Their gray wings have a white border and black tips. Seagulls can be found all over the planet including the margins of Antarctica, and are found in the high Arctic, as well. Seagulls are seabirds usually grey or white, often with black markings on the head or wings. After leaving the nest, the juveniles stay together in large groups, seldom associating with the adult gulls. They are watched over by a few adult males. When a pelican comes to the surface with a fish, the gull is often waiting to try to take the fish out of its pouch. Even though the pomarine skua looks very similar to the arctic skua, genetic studies have shown that it is much more closely related to the great skua. They can feed during the day and night, but it has been suggested that Red-legged Kittiwake, with its larger eyes, is better adapted for catching prey that migrate to the ocean surface during the nighttime. The Iceland Gull has no darkness in its wingtips, or only very little, compared to Kumlien's version which has more darkness in the wingtips. The Thayer's Gull is a “four-year gull,” in that it takes four years to reach adult plumage. Black-legged kittiwake Hi Clare. Thayer's Gulls forage while swimming, walking, or flying. The black-legged kittiwake prefers to eat marine invertebrates, plankton, and fish. The bill is yellow with a red spot near the tip of the lower mandible, and the feet and legs are dark pink. During the summer months, the adult's back and wings are pale gray, and the trailing edge of their wings is white, with a black wing-tip. Click the following link for facts and information on how gulls fly. Great Black-Backed Gulls are often found in the company of herring gulls and the two species will even nest together in mixed colonies. The juvenile Ivory Gulls then follow the adults on migration, where they continue to beg for food. The western form known as "Kumlien's Gull," Larus glaucoides kumlieni, (bottom left picture) breeds in Canada and shows variable amounts of dark coloration in the wingtips. Eggs are laid from early May onwards with two or three being the usual number. They can stay on Svalbard or other northern areas during the summer, and then migrate south to Antarctica for their winter «vacation». It is a carnivore as well as a scavenger. People have fainted when hit by an attacking great skua. The graellsii subspecies is the palest of the subspecies, with its back being much lighter than the black wingtips. Ivory Gulls are arctic birds that range across Northern Canada, Greenland, and Arctic Western Europe. There is not actually a single species called the seagull, but people all over the world refer to them as seagulls. Their head, neck, and under parts are white. They have black eyes, black legs and feet. My hope is that my site will make your reseach on gulls much easier. Both parents feed the young and brood them, taking turns so that one parent is present at all times.
