Macronectes Halli Immature In Flight - SE Tasmania
Giant petrels form a genus, ''Macronectes'', from the family Procellariidae, which consists of two species. They are the largest birds of this family. Both species are restricted to the Southern Hemisphere, and though their distributions overlap significantly, with both species breeding on the Prince Edward Islands, Crozet Islands, Kerguelen Islands, Macquarie Island, and South Georgia, many southern giant petrels nest farther south, with colonies as far south as Antarctica. Giant petrels are extremely aggressive predators and scavengers, inspiring another common name, the stinker. South Sea whalers used to call them gluttons. They are the only member of their family that is capable of walking on land. Taxonomy The genus ''Macronectes'' was introduced in 1905 by the American ornithologist Charles Wallace Richmond to accommodate what is now the southern giant petrel. It replaced the previous genus ''Ossifraga'' which was found to have been earlier applied to a different group of ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Charles Wallace Richmond
Charles Wallace Richmond (December 31, 1868 – May 19, 1932) was an American ornithologist. He is best remembered for a compilation of the Latin names of birds that is called the Richmond Index. Life and work He was born in Kenosha, Wisconsin and was the eldest son of Edward Leslie and Josephine Ellen Richmond. His mother died when he was 12. His father who was a railway mail clerk moved to Washington, D.C. and joined the Government Printing House there. His father remarried and he had the additional duty of taking care of younger stepbrothers. During his early life he earned extra income for the family by leaving school and working as a page in the House of Representatives. At the age of 15 he got a position as a messenger in the Geological Survey. In 1897 he graduated after studied medicine in Georgetown University and in the next year he married Louise H. Seville. While still at Wisconsin he had collected the eggs of a Kingbird and when he moved to Washington, in 1881. He visi ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Ancient Greek
Ancient Greek includes the forms of the Greek language used in ancient Greece and the ancient world from around 1500 BC to 300 BC. It is often roughly divided into the following periods: Mycenaean Greek (), Dark Ages (), the Archaic period (), and the Classical period (). Ancient Greek was the language of Homer and of fifth-century Athenian historians, playwrights, and philosophers. It has contributed many words to English vocabulary and has been a standard subject of study in educational institutions of the Western world since the Renaissance. This article primarily contains information about the Epic and Classical periods of the language. From the Hellenistic period (), Ancient Greek was followed by Koine Greek, which is regarded as a separate historical stage, although its earliest form closely resembles Attic Greek and its latest form approaches Medieval Greek. There were several regional dialects of Ancient Greek, of which Attic Greek developed into Koine. Dia ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
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 ...

Albatross
Albatrosses, of the biological family Diomedeidae, are large seabirds related to the procellariids, storm petrels, and diving petrels in the order Procellariiformes (the tubenoses). They range widely in the Southern Ocean and the North Pacific. They are absent from the North Atlantic, although fossil remains show they once occurred there and occasional vagrants are found. Albatrosses are among the largest of flying birds, and species of the genus ''Diomedea'' (great albatrosses) have the longest wingspans of any extant birds, reaching up to . The albatrosses are usually regarded as falling into four genera, but disagreement exists over the number of species. Albatrosses are highly efficient in the air, using dynamic soaring and slope soaring to cover great distances with little exertion. They feed on squid, fish, and krill by either scavenging, surface seizing, or diving. Albatrosses are colonial, nesting for the most part on remote oceanic islands, often with several spe ...

Macronectes Halli
The northern giant petrel (''Macronectes halli''), also known as Hall's giant petrel, is a large predatory seabird of the southern oceans. Its distribution overlaps broadly, but is slightly north of, the similar southern giant petrel (''Macronectes giganteus''). Taxonomy The northern giant petrel was species description, formally described in 1912 by the Australian born ornithologist Gregory Mathews as a subspecies of the southern giant petrel with the trinomial name ''Macronectes giganteus halli''. The specific epithet ''halli'' was chosen to honour the Australian ornithologist Robert Hall (ornithologist), Robert Hall who had described the birds breeding on the Kerguelen Islands. The northern giant petrel is now considered to be a separate species and has the binomial name ''Macronectes halli''. It is monotypic: no subspecies are recognised. The genus name combines the Ancient Greek ''makros'' meaning "great" and ''nēktēs'' meaning "swimmer". The name "petrel" refers to the Bi ...

Macronectes Giganteus
The southern giant petrel (''Macronectes giganteus''), also known as the Antarctic giant petrel, giant fulmar, stinker, and stinkpot, is a large seabird of the southern oceans. Its distribution overlaps broadly with the similar northern giant petrel, though it overall is centered slightly further south. Adults of the two species can be distinguished by the colour of their bill-tip: greenish in the southern and reddish in the northern. Taxonomy The southern giant petrel was formally described in 1789 by the German naturalist Johann Friedrich Gmelin. He placed it with all the other petrels in the genus ''Procellaria'' and coined the binomial name ''Procellaria gigantea''. Gmelin cited the "giant petrel" that had been described and illustrated in 1785 by the English ornithologist John Latham in his ''A General Synopsis of Birds''. The southern giant petrel is now placed with the northern giant petrel in the genus ''Macronectes'' that was introduced in 1905 by the American ornitholo ...

Snow Petrel
The snow petrel (''Pagodroma nivea'') is the only member of the genus ''Pagodroma.'' It is one of only three birds that has been seen at the Geographic South Pole, along with the Antarctic petrel and the south polar skua, which have the most southerly breeding sites of any bird, inland in Antarctica. Taxonomy The snow petrel was described in 1777 by the German naturalist Georg Forster in his book ''A Voyage Round the World''. He had accompanied James Cook on Cook's second voyage to the Pacific. We particularly observed a petrel, about the size of a pigeon, entirely white, with a black bill and blueish feet; it constantly appeared about the icy masses, and may be looked upon as a sure fore-runner of ice. Forster placed the snow petrel in the genus ''Procellaria'' that had been erected for the petrels by Carl Linnaeus in 1758 and coined the binomial name ''Procellaria nivea''. The snow petrel is now the only species placed in the genus ''Pagodroma'' that was introduced for the ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Antarctic Petrel
The Antarctic petrel (''Thalassoica antarctica'') is a boldly marked dark brown and white petrel, found in Antarctica, most commonly in the Ross and Weddell Seas. They eat Antarctic krill, fish, and small squid. They feed while swimming but can dive from both the surface and the air. Taxonomy and systematics Captain James Cook saw the Antarctic petrel on his second voyage to the south Pacific. In 1777 both Cook and the naturalist Georg Forster mentioned the petrel in their separate accounts of the voyage. Forster wrote: On the 17th, in the forenoon, we crossed the antarctic circle, and advanced into the southern frigid zone, which had hitherto remained impenetrable to all navigators. Some days before this period we had seen a new species of petrel, of a brown colour, with a white belly and rump, and a large white spot on the wings, which we now named the antarctic petrel, as we saw great flights of twenty on thirty of them hereabouts, of which we shot many that unfortunately neve ...

Fulmar
The fulmars are tubenosed seabirds of the family Procellariidae. The family consists of two extant species and two extinct fossil species from the Miocene. Fulmars superficially resemble gulls, but are readily distinguished by their flight on stiff wings, and their tube noses. They breed on cliffs, laying one or rarely two eggs on a ledge of bare rock or on a grassy cliff. Outside the breeding season, they are pelagic, feeding on fish, squid and shrimp in the open ocean. They are long-lived for birds, living for up to 40 years. Historically, the northern fulmar lived on the Isle of St Kilda, where it was extensively hunted. The species has expanded its breeding range southwards to the coasts of England and northern France. Taxonomy The genus ''Fulmarus'' was introduced in 1826 by the English naturalist James Stephens. The name comes from the Old Norse ''Fúlmár'' meaning "foul-mew" or "foul-gull" because of the birds' habit of ejecting a foul-smelling oil. The type species ...
