Woodcock
The woodcocks are a group of seven or eight very similar living species of wading birds in the genus ''Scolopax''. The genus name is Latin for a snipe or woodcock, and until around 1800 was used to refer to a variety of waders. The English name its first recorded in about 1050. According to the Harleian Miscellany, a group of woodcocks is called a "fall". Taxonomy The genus ''Scolopax'' was introduced in 1758 by the Swedish naturalist Carl Linnaeus in the tenth edition of his ''Systema Naturae''. The genus name is Latin for a snipe or woodcock. The type species is the Eurasian woodcock (''Scolopax rusticola''). Only two woodcocks are widespread, the others being localized island endemics. Most are found in the Northern Hemisphere but a few range into the Greater Sundas, Wallacea and New Guinea. Their closest relatives are the typical snipes of the genus ''Gallinago''. As with many other sandpiper genera, the lineages that led to ''Gallinago'' and ''Scolopax'' likely diverged ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Eurasian Woodcock
The Eurasian woodcock (''Scolopax rusticola'') is a medium-small wading bird found in temperate and subarctic Eurasia. It has cryptic camouflage to suit its woodland habitat, with reddish-brown upperparts and buff-coloured underparts. Its eyes are set far back on its head to give it 360-degree vision and it probes in the ground for food with its long, sensitive bill, making it vulnerable to cold weather when the ground remains frozen. The male performs a courtship flight known as "roding" at dusk in spring. When threatened, the female can carry chicks between her legs, in her claws, or on her back while flying, though this is rarely witnessed. The world population is estimated to be 14 million to 16 million birds. Taxonomy The Eurasian woodcock was formally described by the Swedish naturalist Carl Linnaeus in 1758 in the tenth edition of his ''Systema Naturae'' under the current binomial name ''Scolopax rusticola''. The genus name is Latin for a snipe or woodcock. The specifi ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
American Woodcock
The American woodcock (''Scolopax minor''), sometimes colloquially referred to as the timberdoodle, the bogsucker, the hokumpoke, and the Labrador twister, is a small shorebird species found primarily in the eastern half of North America. Woodcocks spend most of their time on the ground in brushy, young-forest habitats, where the birds' brown, black, and gray plumage provides excellent camouflage. The American woodcock is the only species of woodcock inhabiting North America. Although classified with the sandpipers and shorebirds in the family Scolopacidae, the American woodcock lives mainly in upland settings. Its many folk names include timberdoodle, bogsucker, night partridge, brush snipe, hokumpoke, and becasse. The population of the American woodcock has fallen by an average of slightly more than 1% annually since the 1960s. Most authorities attribute this decline to a loss of habitat caused by forest maturation and urban development. Because of the male woodcock's unique, b ...

Amami Woodcock
The Amami woodcock (''Scolopax mira'') is a medium-sized wader. It is slightly larger and longer-legged than Eurasian woodcock, and may be conspecific. This species is a restricted-range endemic found only in forests on two small islands of the Amami Islands chain in South Japan. Insofar as its habits are known, they are similar to Eurasian woodcock. Taxonomy and systematics The Amami woodcock was originally described as a subspecies of the Eurasian woodcock, due to a juvenile that resembled the Eurasian woodcock in coloration. Later, some argued that the Amami woodcock was a distinct species—Kobayashi in 1979 and Cramp A cramp is a sudden, involuntary, painful skeletal muscle contraction or overshortening associated with electrical activity; while generally temporary and non-damaging, they can cause significant pain and a paralysis-like immobility of the aff ... & Simmons in 1983.

Gallinago
''Gallinago'' is a genus of birds in the wader family Scolopacidae, containing 18 species. Taxonomy The name ''Gallinago'' was introduced by the French zoologist Mathurin Jacques Brisson in 1760 as a subdivision of the genus ''Scolopax''. Brisson did not use Carl Linnaeus's binomial system of nomenclature and although many of Brisson's genera had been adopted by ornithologists, his subdivision of genera were generally ignored. Instead, the erection of the genus ''Gallinago'' for the snipes was credited to the German zoologist Carl Ludwig Koch in a book published in 1816. But in 1920 it was discovered that the German naturalist Johann Samuel Traugott Frenzel had erected the genus ''Capella'' for the snipes in 1801. As his publication predated Koch's use of ''Gallinago'' it took precedence. The American Ornithologists' Union switched to ''Capella'' in 1921 and in 1934 the American ornithologist James L. Peters used ''Capella'' for the woodcocks in his influential ''Check-list of B ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Ryukyu Islands
The , also known as the or the , are a chain of Japanese islands that stretch southwest from Kyushu to Taiwan: the Ōsumi, Tokara, Amami, Okinawa, and Sakishima Islands (further divided into the Miyako and Yaeyama Islands), with Yonaguni the westernmost. The larger are mostly high islands and the smaller mostly coral. The largest is Okinawa Island. The climate of the islands ranges from humid subtropical climate (Köppen climate classification ''Cfa'') in the north to tropical rainforest climate (Köppen climate classification ''Af'') in the south. Precipitation is very high and is affected by the rainy season and typhoons. Except the outlying Daitō Islands, the island chain has two major geologic boundaries, the Tokara Strait (between the Tokara and Amami Islands) and the Kerama Gap (between the Okinawa and Miyako Islands). The islands beyond the Tokara Strait are characterized by their coral reefs. The Ōsumi and Tokara Islands, the northernmost of the islands, fall un ...

Bird
Birds are a group of warm-blooded vertebrates constituting the class Aves (), characterised by feathers, toothless beaked jaws, the laying of hard-shelled eggs, a high metabolic rate, a four-chambered heart, and a strong yet lightweight skeleton. Birds live worldwide and range in size from the bee hummingbird to the ostrich. There are about ten thousand living species, more than half of which are passerine, or "perching" birds. Birds have whose development varies according to species; the only known groups without wings are the extinct moa and elephant birds. Wings, which are modified forelimbs, gave birds the ability to fly, although further evolution has led to the loss of flight in some birds, including ratites, penguins, and diverse endemic island species. The digestive and respiratory systems of birds are also uniquely adapted for flight. Some bird species of aquatic environments, particularly seabirds and some waterbirds, have further evolved for swimming. B ...

Carl Linnaeus
Carl Linnaeus (; 23 May 1707 – 10 January 1778), also known after his ennoblement in 1761 as Carl von Linné Blunt (2004), p. 171. (), was a Swedish botanist, zoologist, taxonomist, and physician who formalised binomial nomenclature, the modern system of naming organisms. He is known as the "father of modern taxonomy". Many of his writings were in Latin; his name is rendered in Latin as and, after his 1761 ennoblement, as . Linnaeus was born in Råshult, the countryside of Småland, in southern Sweden. He received most of his higher education at Uppsala University and began giving lectures in botany there in 1730. He lived abroad between 1735 and 1738, where he studied and also published the first edition of his ' in the Netherlands. He then returned to Sweden where he became professor of medicine and botany at Uppsala. In the 1740s, he was sent on several journeys through Sweden to find and classify plants and animals. In the 1750s and 1760s, he continued to collect an ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Million Years Ago
The abbreviation Myr, "million years", is a unit of a quantity of (i.e. ) years, or 31.556926 teraseconds. Usage Myr (million years) is in common use in fields such as Earth science and cosmology. Myr is also used with Mya (million years ago). Together they make a reference system, one to a quantity, the other to a particular place in a year numbering system that is ''time before the present''. Myr is deprecated in geology, but in astronomy ''Myr'' is standard. Where "myr" ''is'' seen in geology it is usually "Myr" (a unit of mega-years). In astronomy it is usually "Myr" (Million years). Debate In geology a debate remains open concerning the use of ''Myr'' (duration) plus ''Ma'' (million years ago) versus using only the term ''Ma''. In either case the term '' Ma'' is used in geology literature conforming to ISO 31-1 (now ISO 80000-3) and NIST 811 recommended practices. Traditional style geology literature is written The "ago" is implied, so that any such year number "X Ma" ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Speciation
Speciation is the evolutionary process by which populations evolve to become distinct species. The biologist Orator F. Cook coined the term in 1906 for cladogenesis, the splitting of lineages, as opposed to anagenesis, phyletic evolution within lineages. Charles Darwin was the first to describe the role of natural selection in speciation in his 1859 book ''On the Origin of Species''. He also identified sexual selection as a likely mechanism, but found it problematic. There are four geographic modes of speciation in nature, based on the extent to which speciating populations are isolated from one another: allopatric speciation, allopatric, peripatric speciation, peripatric, parapatric speciation, parapatric, and sympatric speciation, sympatric. Speciation may also be induced artificially, through animal husbandry, agriculture, or laboratory experiments of speciation, laboratory experiments. Whether genetic drift is a minor or major contributor to speciation is the subject of much ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Subfossil
A fossil (from Classical Latin , ) is any preserved remains, impression, or trace of any once-living thing from a past geological age. Examples include bones, shells, exoskeletons, stone imprints of animals or microbes, objects preserved in amber, hair, petrified wood and DNA remnants. The totality of fossils is known as the ''fossil record''. Paleontology is the study of fossils: their age, method of formation, and evolutionary significance. Specimens are usually considered to be fossils if they are over 10,000 years old. The oldest fossils are around 3.48 billion years old to 4.1 billion years old. Early edition, published online before print. The observation in the 19th century that certain fossils were associated with certain rock strata led to the recognition of a geological timescale and the relative ages of different fossils. The development of radiometric dating techniques in the early 20th century allowed scientists to quantitatively measure the absolute ...
