Peruvian Thick-knee
The Peruvian thick-knee (''Burhinus superciliaris'') is a species of bird in the family Burhinidae. It is found in Chile, Ecuador, and Peru. Its natural habitats are subtropical or tropical dry shrubland, subtropical or tropical seasonally wet or flooded lowland grassland, and pastureland. It is a ground-dwelling bird and feeds on insects and small animals. Taxonomy The Peruvian thick-knee was species description, formally described in 1843 by the Swiss naturalist Johann Jakob von Tschudi from a speciment collected in the coastal region of Peru. He coined the binomial name ''Oedicnenus superciliaris'' (the genus name is a typographic error for ''Oedicnemus''). The specific epithet is Modern Latin meaning "eyebrowed" (''supercillium'' is the Latin word for "eyebrow"). The Peruvian thick-knee is now placed in the genus ''Burhinus'' that was erected in 1811 by the German zoologist Johann Karl Wilhelm Illiger. The species is monotypic: no subspecies are recognised.

Johann Jakob Von Tschudi
Johann Jakob von Tschudi (25 July 1818 – 8 October 1889) was a Switzerland, Swiss Natural history, naturalist, explorer and diplomat. Biography Tschudi was born in Glarus to Johann Jakob Tschudi, a merchant, and Anna Maria Zwicky. He studied natural sciences and medicine at the universities of Neuchâtel, Leiden and Paris. In 1838 he travelled to Peru, where he remained for five years exploring and collecting plants in the Andes. He went to Vienna in 1843. In 1845 he described 18 new species of South American reptiles. Between 1857 and 1859 he visited Brazil and other countries in South America. In 1860 he was appointed Swiss ambassador to Brazil, remaining so until 1868, and again spent time exploring the country and collecting plants for the museums of Neuchâtel, Glarus, and Freiburg. In 1868 he became minister to Vienna. Peru He wrote a textbook on Peru called ''Peruvian antiquities'' in which he recorded various aspects of Peruvian life and history. In his book he explai ...

Johann Karl Wilhelm Illiger
Johann Karl Wilhelm Illiger (19 November 1775 – 10 May 1813) was a German entomologist and zoologist. Illiger was the son of a merchant in Braunschweig. He studied under the entomologist Johann Christian Ludwig Hellwig, Johann Hellwig, and later worked on the zoological collections of Johann Centurius Hoffmannsegg. Illiger was professor and director of the "zoological museum" (which is the Natural History Museum, Berlin, Natural History Museum of Berlin in the present day) from its formation in 1810 until his death. He was the author of ''Prodromus systematis mammalium et avium'' (1811), which was an overhaul of the Carl Linnaeus, Linnaean system. It was a major influence on the adoption of the concept of the Family (biology), family. He also edited the ''Magazin für Insektenkunde'', widely known as "Illiger's Magazine". In 1811 he introduced the taxonomic order Proboscidea for elephants, the American Mastodon, American mastodon and the woolly mammoth. He also described the ...

Birds Described In 1843
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. Birds ...

Least Concern
A least-concern species is a species that has been categorized by the International Union for Conservation of Nature (IUCN) as evaluated as not being a focus of species conservation because the specific species is still plentiful in the wild. They do not qualify as threatened, near threatened, or (before 2001) conservation dependent. Species cannot be assigned the "Least Concern" category unless they have had their population status evaluated. That is, adequate information is needed to make a direct, or indirect, assessment of its risk of extinction based on its distribution or population status. Evaluation Since 2001 the category has had the abbreviation "LC", following the IUCN 2001 Categories & Criteria (version 3.1). Before 2001 "least concern" was a subcategory of the "Lower Risk" category and assigned the code "LR/lc" or lc. Around 20% of least concern taxa (3261 of 15636) in the IUCN database still use the code "LR/lc", which indicates they have not been re-evaluate ...

IUCN
The International Union for Conservation of Nature (IUCN; officially International Union for Conservation of Nature and Natural Resources) is an international organization working in the field of nature conservation and sustainable use of natural resources. It is involved in data gathering and analysis, research, field projects, advocacy, and education. IUCN's mission is to "influence, encourage and assist societies throughout the world to conserve nature and to ensure that any use of natural resources is equitable and ecologically sustainable". Over the past decades, IUCN has widened its focus beyond conservation ecology and now incorporates issues related to sustainable development in its projects. IUCN does not itself aim to mobilize the public in support of nature conservation. It tries to influence the actions of governments, business and other stakeholders by providing information and advice and through building partnerships. The organization is best known to the wider ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Cerros De Naupe
Cerros is an Eastern Lowland Maya archaeological site in northern Belize that functioned from the Late Preclassic to the Postclassic period. The site reached its apogee during the Mesoamerican Late Preclassic and at its peak, it held a population of approximately 1,089 people. The site is strategically located on a peninsula at the mouth of the New River where it empties into Chetumal Bay on the Caribbean coast. As such, the site had access to and served as an intermediary link between the coastal trade route that circumnavigated the Yucatán Peninsula and inland communities. The inhabitants of Cerros constructed an extensive canal system and utilized raised-field agriculture. Site organization The core of the site immediately abuts the bay and consists of several relatively large structures and stepped pyramids, an acropolis complex, and two ballcourts. Bounding the southern side of the site is a crescent-shaped canal network that encloses the central portion of the site and ...

Vanellus
''Vanellus'' is the genus of waders which provisionally contains all lapwings except red-kneed dotterel, ''Erythrogonys cinctus''. The name "''vanellus''" is Latin for "little fan", ''vanellus'' being the diminutive of ''vannus'' ("Winnowing#In Greek culture, winnowing fan"). The name is in reference to the sound lapwings' wings make in flight. Description These long-legged waders mostly have strongly patterned plumage. Although the most familiar Eurasian lapwing, ''Vanellus vanellus'' (northern lapwing), has a wispy Crest (feathers), crest, only two other species do so. Red or yellow facial wattle (anatomy), wattles are a more typical decoration. Only northern, sociable, white-tailed, grey-headed and brown-chested lapwings are truly bird migration, migratory species. The Andean lapwing moves downhill in winter. Spur-winged, blacksmith, river, southern, Andean and pied lapwings are boldly patterned, red-eyed species with a spurred carpal (wrist) joint. Many species have wattle ...

Camouflage
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, as well as making general aiming easier. 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 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 o ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Ostrich
Ostriches are large flightless birds of the genus ''Struthio'' in the order Struthioniformes, part of the infra-class Palaeognathae, a diverse group of flightless birds also known as ratites that includes the emus, rheas, and kiwis. There are two living species of ostrich: the common ostrich, native to large areas of sub-Saharan Africa and the Somali ostrich, native to the Horn of Africa. The common ostrich was also historically native to the Arabian Peninsula, and ostriches were present across Asia as far east as Mongolia during the Late Pleistocene and possibly into the Holocene. They lay the largest eggs of any living land animal. With the ability to run at 70 km/h (43.5 mph), they are the fastest birds on land. They are farmed worldwide, particularly for their feathers as they are used as decoration and feather dusters. Their skin is also used for leather products. They are the heaviest living birds. Taxonomic history The genus ''Struthio'' was first described b ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Subspecies
In biological classification, subspecies is a rank below species, used for populations that live in different areas and vary in size, shape, or other physical characteristics (morphology), but that can successfully interbreed. Not all species have subspecies, but for those that do there must be at least two. Subspecies is abbreviated subsp. or ssp. and the singular and plural forms are the same ("the subspecies is" or "the subspecies are"). In zoology, under the International Code of Zoological Nomenclature, the subspecies is the only taxonomic rank below that of species that can receive a name. In botany and mycology, under the International Code of Nomenclature for algae, fungi, and plants, other infraspecific ranks, such as variety, may be named. In bacteriology and virology, under standard bacterial nomenclature and virus nomenclature, there are recommendations but not strict requirements for recognizing other important infraspecific ranks. A taxonomist decides whether ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Monotypic
In biology, a monotypic taxon is a taxonomic group (taxon) that contains only one immediately subordinate taxon. A monotypic species is one that does not include subspecies or smaller, infraspecific taxa. In the case of genera, the term "unispecific" or "monospecific" is sometimes preferred. In botanical nomenclature, a monotypic genus is a genus in the special case where a genus and a single species are simultaneously described. In contrast, an oligotypic taxon contains more than one but only a very few subordinate taxa. Examples Just as the term ''monotypic'' is used to describe a taxon including only one subdivision, the contained taxon can also be referred to as monotypic within the higher-level taxon, e.g. a genus monotypic within a family. Some examples of monotypic groups are: Plants * In the order Amborellales, there is only one family, Amborellaceae and there is only one genus, '' Amborella'', and in this genus there is only one species, namely ''Amborella trichopoda. ...
