Lapwing
Lapwings (subfamily Vanellinae) are any of various ground-nesting birds (Family (biology), family Charadriidae) akin to plovers and dotterels. They range from in length, and are noted for their slow, irregular wingbeats in flight and a shrill, wailing cry. The traditional terms "plover", "lapwing", and "dotterel" do not correspond exactly to current taxonomic models; thus, several of the Vanellinae are often called plovers, and Red-kneed dotterel, one a dotterel, while a few of the "true" plovers (subfamily Charadriinae) are known colloquially as lapwings. In general, a lapwing can be thought of as a larger plover. In Europe's Anglophone countries, ''lapwing'' refers specifically to the northern lapwing, the only member of this group to occur in most of the continent and thus the first bird to go by the English name ''lapwing'' (also known as ''peewit'' or ''pyewipe''). In the fanciful taxonomy promoted by medieval courtesy books, a group of lapwings was called a "deceit". Sy ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Northern Lapwing
The northern lapwing (''Vanellus vanellus''), also known as the peewit or pewit, tuit or tewit, green plover, or (in Ireland and Great Britain) pyewipe or just lapwing, is a bird in the lapwing subfamily. It is common through temperate Palearctic, Eurosiberia. Taxonomy The northern lapwing was Species description, formally described by the Swedish naturalist Carl Linnaeus in 1758 in the 10th edition of Systema Naturae, tenth edition of his ''Systema Naturae'' under the binomial nomenclature, binomial name ''Tringa vanellus''. The species is now placed with the other lapwings in the genus ''Vanellus'' that was introduced by the French zoologist Mathurin Jacques Brisson in 1760. The scientific name ''Vanellus'' is Medieval Latin for the northern lapwing and derives from ''vannus'', a Winnowing#In Greek culture, winnowing fan. The species is monotypic: no subspecies are recognised. The name ''lapwing'' has been variously attributed to the "lapping" sound its wings make in flight, f ...

Pied Plover
The pied plover (''Hoploxypterus cayanus''), also known as the pied lapwing, is a species of bird in the family Charadriidae. It is a bird of least concern according to the IUCN and can be found in northern South America. The species name ''cayanus'' refers to Cayenne, the capital of French Guiana, where the pied plover can be found. There is confusion around its common name. Historically, the pied plover was considered to be a plover, which is a bird part of the subfamily Charadriinae. Most recently, it has been moved to the subfamily Vanellinae, which are the lapwings. The pied plover is still referred to as a plover because it physically resembles that group of birds in shape and size. However, based on taxonomy, it is more correct to refer to it as a lapwing. Taxonomy The pied plover belongs to the order Charadriiformes known as the shorebirds. It is placed within the family Charadriidae and is the only species placed in the genus ''Hoploxypterus'' that was introduced in ...

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 ...

Blacksmith Lapwing
The blacksmith lapwing or blacksmith plover (''Vanellus armatus'') is a lapwing species that occurs commonly from Kenya through central Tanzania to southern and southwestern Africa. The vernacular name derives from the repeated metallic 'tink, tink, tink' alarm call, which suggests a blacksmith's hammer striking an anvil. Description Blacksmith lapwings are very boldly patterned in black, grey and white, possibly warning colours to predators. It is one of five lapwing species (two African, one Asian and two Neotropical) that share the characteristics of red eyes and a bold pied plumage, with a carpal (wing) spur adorning the wrist joint; a sharp black protrusion which they use to aggressively defend their young from potential threats, through persistent aerial dives typically targeting the head. The portions of the bird's body bare to plumage average a black coloration for the bill, and either a black or white-grey dappling on the legs. Females average larger and heavier but the ...

Red-kneed Dotterel
The red-kneed dotterel (''Erythrogonys cinctus'') is a species of plover in a monotypic genus in the subfamily Vanellinae. It is often gregarious and will associate with other waders of its own and different species, even when nesting. It is nomadic and sometimes irruption, irruptive. Description Adults distinctively marked: black cap or hood from bill, extending below eyes, merging at nape to grey-brown of back. White chin and throat. Broad black band on breast joining nape and also extending to flanks as chestnut stripe. Belly and vent white. Back and mantle grey-brown, mainly black upperwing with white trailing edge. Upper leg, including tarsal joint or "knee", red. Bill red with dark tip. Distribution The red-kneed dotterel is native to mainland Australia, Papua New Guinea, and Indonesia, and has occurred as a vagrant in Tasmania, Palau and New Zealand. Habitat Mainly margins of shallow ephemeral and permanent freshwater wetlands, occasionally saline wetlands, but ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Basal (evolution)
In phylogenetics, basal is the direction of the ''base'' (or root) of a rooted phylogenetic tree or cladogram. The term may be more strictly applied only to nodes adjacent to the root, or more loosely applied to nodes regarded as being close to the root. Note that extant taxa that lie on branches connecting directly to the root are not more closely related to the root than any other extant taxa. While there must always be two or more equally "basal" clades sprouting from the root of every cladogram, those clades may differ widely in taxonomic rank, species diversity, or both. If ''C'' is a basal clade within ''D'' that has the lowest rank of all basal clades within ''D'', ''C'' may be described as ''the'' basal taxon of that rank within ''D''. The concept of a ' key innovation' implies some degree of correlation between evolutionary innovation and diversification. However, such a correlation does not make a given case predicable, so ancestral characters should not be imputed to ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
International Ornithologists' Union
The International Ornithologists' Union (IOU) is an international organization for the promotion of ornithology Ornithology, from Ancient Greek ὄρνις (''órnis''), meaning "bird", and -logy from λόγος (''lógos''), meaning "study", is a branch of zoology dedicated to the study of birds. Several aspects of ornithology differ from related discip .... It links basic and applied research and nurtures education and outreach activities. Specifically, the IOU organizes and funds global congresses on ornithology at regular intervals, sets up and supports commissions and committees on various aspects of avian biology and conservation, and initiates and backs other international ornithological activities with specific aims consistent with its own mission and goal. It discloses the names and professional affiliations of its members on its website to encourage international collaboration and networking. The IOU acts as the Ornithology Section of the International Union of Biologi ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Last Common Ancestor
A most recent common ancestor (MRCA), also known as a last common ancestor (LCA), is the most recent individual from which all organisms of a set are inferred to have descended. The most recent common ancestor of a higher taxon is generally assumed to have been a species. The term is also used in reference to the ancestry of groups of genes (haplotypes) rather than organisms. The ancestry of a set of individuals can sometimes be determined by referring to an established pedigree, although this may refer only to patrilineal or matrilineal lines for sexually-reproducing organisms with two parents, four grandparents, etc. However, in general, it is impossible to identify the exact MRCA of a large set of individuals, but an estimate of the time at which the MRCA lived can often be given. Such ''time to most recent common ancestor'' (''TMRCA'') estimates can be given based on DNA test results and established mutation rates as practiced in genetic genealogy, or by reference to a non- ...

Clade
In biology, a clade (), also known as a Monophyly, monophyletic group or natural group, is a group of organisms that is composed of a common ancestor and all of its descendants. Clades are the fundamental unit of cladistics, a modern approach to taxonomy adopted by most biological fields. The common ancestor may be an individual, a population, or a species (extinct or Extant taxon, extant). Clades are nested, one in another, as each branch in turn splits into smaller branches. These splits reflect evolutionary history as populations diverged and evolved independently. Clades are termed ''monophyletic'' (Greek: "one clan") groups. Over the last few decades, the cladistic approach has revolutionized biological classification and revealed surprising evolutionary relationships among organisms. Increasingly, taxonomists try to avoid naming Taxon, taxa that are not clades; that is, taxa that are not Monophyly, monophyletic. Some of the relationships between organisms that the molecul ...

Morphology (biology)
Morphology (from Ancient Greek μορφή (morphḗ) "form", and λόγος (lógos) "word, study, research") is the study of the form and structure of organisms and their specific structural features. This includes aspects of the outward appearance (shape, structure, color, pattern, size), as well as the form and structure of internal parts like bones and organs, i.e., anatomy. This is in contrast to physiology, which deals primarily with function. Morphology is a branch of life science dealing with the study of the overall structure of an organism or taxon and its component parts. History The etymology of the word "morphology" is from the Ancient Greek (), meaning "form", and (), meaning "word, study, research". While the concept of form in biology, opposed to function, dates back to Aristotle (see Aristotle's biology), the field of morphology was developed by Johann Wolfgang von Goethe (1790) and independently by the German anatomist and physiologist Karl Fried ...

Lipochrom
Carotenoids () are yellow, orange, and red organic pigments that are produced by plants and algae, as well as several bacteria, archaea, and fungi. Carotenoids give the characteristic color to pumpkins, carrots, parsnips, corn, tomatoes, canaries, flamingos, salmon, lobster, shrimp, and daffodils. Over 1,100 identified carotenoids can be further categorized into two classes xanthophylls (which contain oxygen) and carotenes (which are purely hydrocarbons and contain no oxygen). All are derivatives of tetraterpenes, meaning that they are produced from 8 isoprene units and contain 40 carbon atoms. In general, carotenoids absorb wavelengths ranging from 400 to 550 nanometers (violet to green light). This causes the compounds to be deeply colored yellow, orange, or red. Carotenoids are the dominant pigment in autumn leaf coloration of about 15-30% of tree species, but many plant colors, especially reds and purples, are due to polyphenols. Carotenoids serve two key roles in plants ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
