Puffin
Puffins are any of three species of small alcids (auks) in the bird genus ''Fratercula''. These are pelagic seabirds that feed primarily by diving in the water. They breed in large colonies on coastal cliffs or offshore islands, nesting in crevices among rocks or in burrows in the soil. Two species, the tufted puffin and horned puffin, are found in the North Pacific Ocean, while the Atlantic puffin is found in the North Atlantic Ocean. All puffin species have predominantly black or black and white plumage, a stocky build, and large beaks that get brightly colored during the breeding season. They shed the colorful outer parts of their bills after the breeding season, leaving a smaller and duller beak. Their short wings are adapted for swimming with a flying technique underwater. In the air, they beat their wings rapidly (up to 400 times per minute) in swift flight, often flying low over the ocean's surface.

Atlantic Puffin
The Atlantic puffin ('), also known as the common puffin, is a species of seabird in the auk family. It is the only puffin native to the Atlantic Ocean; two related species, the tufted puffin and the horned puffin is found in the northeastern Pacific. The Atlantic puffin breeds in Russia, Iceland, Ireland, Norway, Greenland, Newfoundland and Labrador, Nova Scotia, and the Faroe Islands, and as far south as Maine in the west and France in the east. It is most commonly found in the Westman Islands, Iceland. Although it has a large population and a wide range, the species has declined rapidly, at least in parts of its range, resulting in it being rated as vulnerable by the IUCN. On land, it has the typical upright stance of an auk. At sea, it swims on the surface and feeds on small fish and crabs, which it catches by diving underwater, using its wings for propulsion. This puffin has a black crown and back, pale grey cheek patches, and a white body and underparts. Its broad, bold ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Manx Shearwater
The Manx shearwater (''Puffinus puffinus'') is a medium-sized shearwater in the seabird family Procellariidae. The scientific name of this species records a name shift: Manx shearwaters were called Manks puffins in the 17th century. Puffin is an Anglo-Norman word (Middle English ''pophyn'') for the cured carcasses of nestling shearwaters. The Atlantic puffin acquired the name much later, possibly because of its similar nesting habits. Taxonomy The shearwaters form part of the family Procellariidae, a widespread group containing nearly 100 species of medium to large seabirds. They have long, narrow wings and the characteristic “tube nose”. Although it was considered a monotypic species, recently an endemic subspecies for the Canary Islands has been proposed ''P. puffinus canariensis''. The large genus ''Puffinus'' includes several species formerly considered to be subspecies of the Manx shearwater, including the yelkouan shearwater, Balearic shearwater, Hutton's shearwater ...

Horned Puffin
The horned puffin (''Fratercula corniculata'') is an auk found in the North Pacific Ocean, including the coasts of Alaska, Siberia and British Columbia. It is a pelagic seabird that feeds primarily by diving for fish. It nests in colonies, often with other auks. It is similar in appearance to the Atlantic puffin, its closest relative of the North Atlantic, but differs by a "horn" of black skin located above the eye, present in adult birds. Etymology The binomial name of this species, ''Fratercula corniculata'', comes from the Medieval Latin ''fratercula'', meaning “friar”; their black-and-white plumage resembling the robes of monks. ''Corniculata'' means “horn-shaped” or “crescent-shaped”, in reference to the black horn above the bird's eye. The vernacular name ''puffin'' – puffed in the sense of swollen – was originally applied to the fatty, salted meat of young birds of the unrelated species, the Manx shearwater (''Puffinus puffinus''), formerly known as the "M ...

Tufted Puffin
The tufted puffin (''Fratercula cirrhata''), also known as crested puffin, is a relatively abundant medium-sized pelagic seabird in the auk family (Alcidae) found throughout the North Pacific Ocean. It is one of three species of puffin that make up the genus ''Fratercula'' and is easily recognizable by its thick red bill and yellow tufts. Description Tufted puffins are around in length with a similar wingspan and weigh about three quarters of a kilogram (1.6 lbs), making them the largest of all the puffins. Birds from the western Pacific population are somewhat larger than those from the eastern Pacific, and male birds tend to be slightly larger than females. They are mostly black with a white facial patch, and, typical of other puffin species, feature a very thick bill which is mostly red with some yellow and occasionally green markings. Their most distinctive feature and namesake are the yellow tufts ( la, cirri) that appear annually on birds of both sexes as the sum ...

Skomer Island
Skomer () or Skomer Island is an island off the coast of Pembrokeshire, in the community of Marloes and St Brides in west Wales. It is well known for its wildlife: around half the world's population of Manx shearwaters nest on the island, the Atlantic puffin colony is the largest in southern Britain, and the Skomer vole (a subspecies of the bank vole) is unique to the island. Skomer is a national nature reserve, a Site of Special Scientific Interest and a Special Protection Area. It is surrounded by a marine nature reserve and is managed by the Wildlife Trust of South and West Wales. Skomer is known for its archaeological interest: stone circles, standing stone and remains of prehistoric houses. Much of the island has been designated an ancient monument. Description The island has an area of . Its highest point is above sea level at Gorse Hill, while the majority of the island sits at around above sea level. Skomer is intersected by a series of slopes and ridges g ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Dow's Puffin
Dow's puffin (''Fratercula dowi'') is an extinct seabird in the auk family described in 2000 from subfossil remains found in the Channel Islands of California. It was approximately as large as the modern horned puffin and its beak appared to have been an intermediate between the rhinoceros auklet and the horned puffin. It lived during the Late Pleistocene and Early Pleistocene on the Channel Islands, where it nested alongside the ancient murrelet, Cassin's auklet and ''Chendytes lawi''. History and naming The first remains of ''Fratercula dowi'' were discovered in late 1986 by G. L. Kennedy and D. R. Muhs. The subfossil, an articulated bird skeleton, was found in a Late Pleistocene eolianite outcrop on San Nicolas Island. This specimen was found lying on its belly with a bent neck and preserved beak tip. Most of the skull, alongside much of the legs and posterior torso had eroded away but a complete fossil egg was discovered closeby. Initial observations by paleornithologist Hi ...

Seabird
Seabirds (also known as marine birds) are birds that are adapted to life within the marine environment. While seabirds vary greatly in lifestyle, behaviour and physiology, they often exhibit striking convergent evolution, as the same environmental problems and feeding niches have resulted in similar adaptations. The first seabirds evolved in the Cretaceous period, and modern seabird families emerged in the Paleogene. In general, seabirds live longer, breed later and have fewer young than other birds do, but they invest a great deal of time in their young. Most species nest in colonies, which can vary in size from a few dozen birds to millions. Many species are famous for undertaking long annual migrations, crossing the equator or circumnavigating the Earth in some cases. They feed both at the ocean's surface and below it, and even feed on each other. Seabirds can be highly pelagic, coastal, or in some cases spend a part of the year away from the sea entirely.

Bird Colony
A bird colony is a large congregation of individuals of one or more species of bird that nest or roost in proximity at a particular location. Many kinds of birds are known to congregate in groups of varying size; a congregation of nesting birds is called a breeding colony. Colonial nesting birds include seabirds such as auks and albatrosses; wetland species such as herons; and a few passerines such as weaverbirds, certain blackbirds, and some swallows. A group of birds congregating for rest is called a communal roost. Evidence of colonial nesting has been found in non- neornithine birds ( Enantiornithes), in sediments from the Late Cretaceous (Maastrichtian) of Romania. Variations on colonial nesting in birds Approximately 13% of all bird species nest colonially. Nesting colonies are very common among seabirds on cliffs and islands. Nearly 95% of seabirds are colonial, leading to the usage, seabird colony, sometimes called a rookery. Many species of terns nest in colonie ...

Beak
The beak, bill, or rostrum is an external anatomical structure found mostly in birds, but also in turtles, non-avian dinosaurs and a few mammals. A beak is used for eating, preening, manipulating objects, killing prey, fighting, probing for food, courtship, and feeding young. The terms ''beak'' and ''rostrum'' are also used to refer to a similar mouth part in some ornithischians, pterosaurs, cetaceans, dicynodonts, anuran tadpoles, monotremes (i.e. echidnas and platypuses, which have a beak-like structure), sirens, pufferfish, billfishes and cephalopods. Although beaks vary significantly in size, shape, color and texture, they share a similar underlying structure. Two bony projections – the upper and lower mandibles – are covered with a thin keratinized layer of epidermis known as the rhamphotheca. In most species, two holes called ''nares'' lead to the respiratory system. Etymology Although the word "beak" was, in the past, generally restricted to the sharpened bills o ...
