Vanellus Vanellus Mobbing Circus Aeruginosus
''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 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, only two other species do so. Red or yellow facial wattles are a more typical decoration. Only northern, sociable, white-tailed, grey-headed and brown-chested lapwings are truly 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 wattles which can be small (black-headed, spot-breasted, red-wattled and banded la ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Vanellus Miles
The masked lapwing (''Vanellus miles'') is a large, common and conspicuous bird native to Australia (particularly the northern and eastern parts of the continent), New Zealand and New Guinea. It spends most of its time on the ground searching for food such as insects and worms, and has several distinctive calls. It is common in Australian fields and open land, and is known for its defensive swooping behaviour during the nesting season. Despite the species being also known as the masked plover and often called the spur-winged plover or just plover in its native range, lapwings are classified to their own subfamily, Vanellinae, and not to the closely related plover subfamily, Charadriinae. There are two subspecies: the nominate subspecies and the southern ''novaehollandiae''. The latter has distinctive black markings on the shoulder and side of the chest, and is sometimes recognized as a separate species: the black-shouldered lapwing (''Vanellus novaehollandiae'').

Medieval Latin
Medieval Latin was the form of Literary Latin used in Roman Catholic Church, Roman Catholic Western Europe during the Middle Ages. It was also the administrative language in the former Western Roman Empire, Roman Provinces of Mauretania, Numidia (Roman province), Numidia and Africa (Roman province), Africa Proconsularis under the Vandals, the Exarchate of Africa, Byzantines and the Kingdom of Altava, Romano-Berber Kingdoms, until it declined after the Arab conquest of North Africa, Arab Conquest. Medieval Latin in Southern and Central Visigothic Kingdom, Visigothic Hispania, conquered by the Arabs immediately after North Africa, experienced a similar fate, only recovering its importance after the Reconquista by the Northern Christian Kingdoms. In this region it served as the primary written language, though local languages were also written to varying degrees. Latin functioned as the main medium of scholarly exchange, as the liturgical language of the Roman Catholic Church, Churc ...

Black-headed Lapwing (Vanellus Tectus Tectus)
The black-headed lapwing or black-headed plover (''Vanellus tectus'') is a large lapwing, a group of largish waders in the family Charadriidae. It is a resident breeder across sub-Saharan Africa from Senegal to Ethiopia, although it has seasonal movements. It lays two or three eggs on a ground scrape. These are conspicuous and unmistakable birds. They are medium-large waders with a black head other than a white forehead, lower face and bands across the rear head and nape. There is a wispy black crest like northern lapwing and the bill and legs are red. The tail is white, tipped black. In flight, the black-headed lapwing's upperwings have black flight feathers and brown coverts separated by a white bar. The underwings are white with black flight feathers. This species is a common breeder in wet lowland habitats close to water. It often feeds in drier habitats, such as golf courses and grassy scrub, picking insects and other invertebrates from the ground. The black-headed lapw ...

Spur-winged Lapwing (Vanellus Spinosus) In Flight
The spur-winged lapwing or spur-winged plover (''Vanellus spinosus'') is a lapwing species, one of a group of largish waders in the family Charadriidae. Taxonomy The spur-winged lapwing was formally described in 1758 by the Swedish naturalist Carl Linnaeus in the tenth edition of his ''Systema Naturae''. He placed it with the plovers in the genus '' Charadrius'' and coined the binomial name ''Charadrius spinosus''. He specified the type locality as Egypt. The specific epithet is from Latin meaning "thorny" (from ''spina'' meaning "thorn"). Linnaeus based his account on a description by the Swedish naturalist Fredrik Hasselquist that had been published in 1757. The spur-winged lapwing is now one of 23 species placed in the genus ''Vanellus'' that was introduced in 1760 by the French naturalist Mathurin Jacques Brisson. The species is monotypic: no subspecies are recognised. Description These are conspicuous and unmistakable birds. They are medium-large waders with black cro ...

Andean Lapwing
The Andean lapwing (''Vanellus resplendens'') is a species of bird in family Charadriidae, the plovers and their relatives. It is found in Argentina, Bolivia, Chile, Colombia, Ecuador, and Peru. Taxonomy and systematics The Andean lapwing was originally described as ''Charadrius resplendens'' and has sometimes been placed in genus ''Ptiloscelys''. It is monotypic. Description The Andean lapwing is about long and weighs . The sexes are alike and have no seasonal changes in plumage. Adults have a creamy gray head and neck with a dark brownish gray patch around the eye. Their upperparts are bronzy green with a purple patch on the wing coverts. Their breast is dark gray and their belly white. Their bill is pinkish orange with a black tip, their eye is reddish, and their legs are also reddish. Juveniles have a brownish head and neck, buff mottling on the breast, and pale buff fringes on the upperparts feathers. Distribution and habitat The Andean lapwing is found in the Andes ...

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 ...

Tropical
The tropics are the regions of Earth surrounding the equator, where the sun may shine directly overhead. This contrasts with the temperate or polar regions of Earth, where the Sun can never be directly overhead. This is because of Earth's axial tilt; the width of the tropics (in latitude) is twice the tilt. The tropics are also referred to as the tropical zone and the torrid zone (see geographical zone). Due to the overhead sun, the tropics receive the most solar energy over the course of the year, and consequently have the highest temperatures on the planet. Even when not directly overhead, the sun is still close to overhead throughout the year, therefore the tropics also have the lowest seasonal variation on the planet; "winter" and "summer" lose their temperature contrast. Instead, seasons are more commonly divided by precipitation variations than by temperature variations. The tropics maintain wide diversity of local climates, such as rain forests, monsoons, sa ...

DNA Sequence
A nucleic acid sequence is a succession of bases within the nucleotides forming alleles within a DNA (using GACT) or RNA (GACU) molecule. This succession is denoted by a series of a set of five different letters that indicate the order of the nucleotides. By convention, sequences are usually presented from the 5' end to the 3' end. For DNA, with its double helix, there are two possible directions for the notated sequence; of these two, the sense strand is used. Because nucleic acids are normally linear (unbranched) polymers, specifying the sequence is equivalent to defining the covalent structure of the entire molecule. For this reason, the nucleic acid sequence is also termed the primary structure. The sequence represents genetic information. Biological deoxyribonucleic acid represents the information which directs the functions of an organism. Nucleic acids also have a secondary structure and tertiary structure. Primary structure is sometimes mistakenly referred to as "prim ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Charadriiformes
Charadriiformes (, from '' Charadrius'', the type genus of family Charadriidae) is a diverse order of small to medium-large birds. It includes about 390 species and has members in all parts of the world. Most charadriiform birds live near water and eat invertebrates or other small animals; however, some are pelagic (seabirds), others frequent deserts, and a few are found in dense forest. Members of this group can also collectively be referred to as shorebirds. Taxonomy, systematics and evolution The order was formerly divided into three suborders: * The waders (or "Charadrii"): typical shorebirds, most of which feed by probing in the mud or picking items off the surface in both coastal and freshwater environments. * The gulls and their allies (or " Lari"): these are generally larger species which take fish from the sea. Several gulls and skuas will also take food items from beaches, or rob smaller species, and some have become adapted to inland environments. * The auks (or "Al ...

Plesiomorph
In phylogenetics, a plesiomorphy ("near form") and symplesiomorphy are synonyms for an ancestral Phenotypic trait, character shared by all members of a clade, which does not distinguish the clade from other clades. Plesiomorphy, symplesiomorphy, apomorphy and synapomorphy, apomorphy, and synapomorphy all mean a trait shared between species because they share an ancestral species. Apomorphic and synapomorphic characteristics convey much information about evolutionary clades and can be used to define taxa. However, plesiomorphic and symplesiomorphic characteristics cannot. The term ''symplesiomorphy'' was introduced in 1950 by German Entomology, entomologist Willi Hennig. Examples A backbone is a plesiomorphic trait shared by birds and mammals, and does not help in placing an animal in one or the other of these two clades. Birds and mammals share this trait because both clades are descended from the same far distant ancestor. Other clades, e.g. snakes, lizards, turtles, fish, ...

Apomorph
In phylogenetics, an apomorphy (or derived trait) is a novel character or character state that has evolved from its ancestral form (or plesiomorphy). A synapomorphy is an apomorphy shared by two or more taxa and is therefore hypothesized to have evolved in their most recent common ancestor. ) In cladistics, synapomorphy implies homology. Examples of apomorphy are the presence of erect gait, fur, the evolution of three middle ear bones, and mammary glands in mammals but not in other vertebrate animals such as amphibians or reptiles, which have retained their ancestral traits of a sprawling gait and lack of fur. Thus, these derived traits are also synapomorphies of mammals in general as they are not shared by other vertebrate animals. Etymology The word —coined by German entomologist Willi Hennig—is derived from the Ancient Greek words (''sún''), meaning "with, together"; (''apó''), meaning "away from"; and (''morphḗ''), meaning "shape, form".
