Snipe Class Sailors
A snipe is any of about 26 wading bird species in three genera in the family Scolopacidae. They are characterized by a very long, slender bill, eyes placed high on the head, and cryptic/camouflaging plumage. ''Gallinago'' snipe have a nearly worldwide distribution, the ''Lymnocryptes'' snipe is restricted to Asia and Europe and the ''Coenocorypha'' snipe is found only in the outlying islands of New Zealand. The four species of painted snipe are not closely related to the typical snipe, and are placed in their own family, the Rostratulidae. Behaviour Snipe search for invertebrates in the mud with a " sewing-machine" action of their long bills. The sensitivity of the bill is caused by filaments belonging to the fifth pair of nerves, which run almost to the tip and open immediately under the soft cuticle in a series of cells; a similar adaptation is found in sandpipers; this adaptation gives this portion of the surface of the premaxillaries a honeycomb-like appearance: with th ...

Common Snipe
The common snipe (''Gallinago gallinago'') is a small, stocky wader native to the Old World. Distribution and habitat The breeding habitats are marshes, bogs, tundra and wet meadows throughout the Palearctic. In the north, the distribution limit extends from Iceland over the north of the British Isles and northern Fennoscandia, where it occurs at around 70°N, as well as through European Russia and Siberia. Here it is mostly on the northern edge of the Taiga zone at 71°N, but reaches 74°N on the east coast of the Taymyr Peninsula. In the east it extends to Anadyr, Kamchatka, Bering Island and the Kuril Islands, The southern boundary of the distribution area in Europe runs through northern Portugal, central France, northern Italy, Bulgaria, and Ukraine, with populations in the west being only very scattered. In Asia, the distribution extends south to northern Turkestan, locally to Afghanistan and the Middle East, through the Altai and further to Manchuria and Ussuri. It is ...

Genus
Genus (; : genera ) is a taxonomic rank above species and below family (taxonomy), family as used in the biological classification of extant taxon, living and fossil organisms as well as Virus classification#ICTV classification, viruses. In binomial nomenclature, the genus name forms the first part of the binomial species name for each species within the genus. :E.g. ''Panthera leo'' (lion) and ''Panthera onca'' (jaguar) are two species within the genus ''Panthera''. ''Panthera'' is a genus within the family Felidae. The composition of a genus is determined by taxonomy (biology), taxonomists. The standards for genus classification are not strictly codified, so different authorities often produce different classifications for genera. There are some general practices used, however, including the idea that a newly defined genus should fulfill these three criteria to be descriptively useful: # monophyly – all descendants of an ancestral taxon are grouped together (i.e. Phylogeneti ...

Sandpiper
Scolopacidae is a large family of shorebirds, or waders, which mainly includes many species known as sandpipers, but also others such as woodcocks, curlews and snipes. Most of these species eat small invertebrates picked out of the mud or soil. Different lengths of bills enable multiple species to feed in the same habitat, particularly on the coast, without direct competition for food. Sandpipers have long bodies and legs, and narrow wings. Most species have a narrow bill, but the form and length are variable. They are small to medium-sized birds, measuring in length. The bills are sensitive, allowing the birds to feel the mud and sand as they probe for food. They generally have dull plumage, with cryptic brown, grey, or streaked patterns, although some display brighter colours during the breeding season. Most species nest in open areas and defend their territories with aerial displays. The nest itself is a simple scrape in the ground, in which the bird typically lays thre ...

Sewing Machine
Diagram of a modern sewing machine Animation of a modern sewing machine as it stitches A sewing machine is a machine used to sew fabric and materials together with thread. Sewing machines were invented during the first Industrial Revolution to decrease the amount of manual sewing work performed in clothing companies. Since the invention of the first sewing machine, generally considered to have been the work of Englishman Thomas Saint in 1790, the sewing machine has greatly improved the efficiency and productivity of the clothing industry. Home sewing machines are designed for one person to sew individual items while using a single stitch type at a time. In a modern sewing machine, the process of stitching has been automated, so that the fabric easily glides in and out of the machine. Early sewing machines were powered by either constantly turning a flywheel handle or with a foot-operated treadle mechanism. Electrically-powered machines were later introduced. Industria ...

Invertebrate
Invertebrates are animals that neither develop nor retain a vertebral column (commonly known as a ''spine'' or ''backbone''), which evolved from the notochord. It is a paraphyletic grouping including all animals excluding the chordata, chordate subphylum Vertebrata, i.e. vertebrates. Well-known Phylum, phyla of invertebrates include arthropods, molluscs, annelids, echinoderms, flatworms, cnidarians, and sponges. The majority of animal species are invertebrates; one estimate puts the figure at 97%. Many invertebrate taxon, taxa have a greater number and diversity of species than the entire subphylum of Vertebrata. Invertebrates vary widely in size, from 10 Micrometre, μm (0.0004 in) myxozoans to the 9–10 m (30–33 ft) colossal squid. Some so-called invertebrates, such as the Tunicata and Cephalochordata, are actually sister chordate subphyla to Vertebrata, being more closely related to vertebrates than to other invertebrates. This makes the "invertebrates" para ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Painted Snipe
The Rostratulidae, commonly known as the painted-snipes, are a family of wading birds that consists of two genera: '' Rostratula'' and '' Nycticryphes''. Description The painted-snipes are short-legged, long-billed birds similar in shape to the true snipes, but their plumage is much more striking. There is sexual dimorphism in both size and plumage, with the males being duller overall and smaller. All three species have large forward pointing eyes. Phylogenetics The family Rostratulidae encompasses two genera and four species, one of which is extinct. Painted-snipes superficially resemble true snipes, but the two taxa are not closely related. Instead the similarity can be attributed to convergent evolution where both groups have been subjected to similar selective pressures, thus promoting the evolution of analogous features such as a long slender bill and legs, mottled cryptic plumage and characteristic body proportions. While less similar in general morphology, the species ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Europe
Europe is a continent located entirely in the Northern Hemisphere and mostly in the Eastern Hemisphere. It is bordered by the Arctic Ocean to the north, the Atlantic Ocean to the west, the Mediterranean Sea to the south, and Asia to the east. Europe shares the landmass of Eurasia with Asia, and of Afro-Eurasia with both Africa and Asia. Europe is commonly considered to be Boundaries between the continents#Asia and Europe, separated from Asia by the Drainage divide, watershed of the Ural Mountains, the Ural (river), Ural River, the Caspian Sea, the Greater Caucasus, the Black Sea, and the waterway of the Bosporus, Bosporus Strait. "Europe" (pp. 68–69); "Asia" (pp. 90–91): "A commonly accepted division between Asia and Europe ... is formed by the Ural Mountains, Ural River, Caspian Sea, Caucasus Mountains, and the Black Sea with its outlets, the Bosporus and Dardanelles."

Asia
Asia ( , ) is the largest continent in the world by both land area and population. It covers an area of more than 44 million square kilometres, about 30% of Earth's total land area and 8% of Earth's total surface area. The continent, which has long been home to the majority of the human population, was the site of many of the first civilisations. Its 4.7 billion people constitute roughly 60% of the world's population. Asia shares the landmass of Eurasia with Europe, and of Afro-Eurasia with both Europe and Africa. In general terms, it is bounded on the east by the Pacific Ocean, on the south by the Indian Ocean, and on the north by the Arctic Ocean. The border of Asia with Europe is a social constructionism, historical and cultural construct, as there is no clear physical and geographical separation between them. A commonly accepted division places Asia to the east of the Suez Canal separating it from Africa; and to the east of the Turkish straits, the Ural Mountains an ...

Jack Snipe
The jack snipe or jacksnipe (''Lymnocryptes minimus'') is a small stocky wader. It is the smallest snipe, and the only member of the genus ''Lymnocryptes''. Features such as its sternum and its continuous 'bobbing up and down' make it quite distinct from other snipes or woodcocks. Taxonomy The jack snipe was formally described in 1764 by the Danish zoologist Morten Thrane Brünnich under the binomial name ''Scolopax minima''. He specified the type locality as the Danish island of Christiansø. Brünnich based his account on "La petite béccassine" that had been described and illustrated in 1760 by the French zoologist Mathurin Jacques Brisson. The jack snipe is now the only species placed in the genus ''Lymnocryptes'' that was introduced in 1826 by the German zoologist Friedrich Boie. The species is considered to be monotypic: no subspecies are recognised. The genus name ''Lymnocryptes'' is from Ancient Greek ''limne'', "marsh" and ''kruptos'', "hidden". The species name '' ...

Plumage
Plumage () is a layer of feathers that covers a bird and the pattern, colour, and arrangement of those feathers. The pattern and colours of plumage differ between species and subspecies and may vary with age classes. Within species, there can be different colour morph (zoology), morphs. The placement of feathers on a bird is not haphazard but rather emerges in organized, overlapping rows and groups, and these are known by standardized names. Most birds moult twice a year, resulting in a breeding or ''nuptial plumage'' and a ''basic plumage''. Many ducks and some other species such as the red junglefowl have males wearing a bright nuptial plumage while breeding and a drab ''eclipse plumage'' for some months afterward. The painted bunting's juveniles have two inserted moults in their first autumn, each yielding plumage like an adult female. The first starts a few days after fledging replacing the ''juvenile plumage'' with an ''auxiliary formative plumage''; the second a month o ...

Camouflaging
Camouflage is the use of any combination of materials, coloration, or illumination for concealment, either by making animals or objects hard to see, or by disguising them as something else. Examples include the leopard's spotted coat, the battledress of a modern soldier, and the leaf-mimic katydid's wings. A third approach, motion dazzle, confuses the observer with a conspicuous pattern, making the object visible but momentarily harder to locate. The majority of camouflage methods aim for crypsis, often through a general resemblance to the background, high contrast disruptive coloration, eliminating shadow, and countershading. In the open ocean, where there is no background, the principal methods of camouflage are transparency, silvering, and countershading, while the bioluminescence, ability to produce light is among other things used for counter-illumination on the undersides of cephalopods such as squid. Some animals, such as chameleons and octopuses, are capable of Active ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
