Recurvirostra
The four species of avocets are a genus, ''Recurvirostra'', of waders in the same avian family as the stilts. The genus name comes from Latin , 'curved backwards' and , 'bill'. The common name is thought to derive from the Italian ( Ferrarese) word . Francis Willughby in 1678 noted it as the "Avosetta of the Italians". Biology Avocets have long legs and they sweep their long, thin, upcurved bills from side to side when feeding in the brackish or saline wetlands they prefer. Their plumage is pied, sometimes also with some red. Members of this genus have webbed feet and readily swim. Their diet consists of aquatic insects and other small creatures. They nest on the ground in loose colonies. In estuarine settings, they may feed on exposed bay muds or mudflats. The pied avocet is the emblem of the Royal Society for the Protection of Birds. Taxonomy The genus ''Recurvirostra'' was introduced in 1758 by Swedish naturalist Carl Linnaeus in the 10th edition of his to contain a sing ...

Pied Avocet
The pied avocet (''Recurvirostra avosetta'') is a large black and white wader in the avocet and stilt family, Recurvirostridae. They breed in temperate Europe and across the Palearctic to Central Asia then on to the Russian Far East. It is a migratory species and most winter in Africa or southern Asia. Some remain to winter in the mildest parts of their range, for example in southern Spain and southern England. The pied avocet is one of the species to which the Agreement on the Conservation of African-Eurasian Migratory Waterbirds (AEWA) applies. Taxonomy The pied avocet was one of the many bird species originally described by Carl Linnaeus in his landmark 1758 10th edition of ''Systema Naturae'', where it was given the binomial name of ''Recurvirostra avosetta''. This species gets its English and scientific names from the Venetian word ''avosetta''. It appeared first in Ulisse Aldrovandi's ''Ornithologia'' (1603).

Red-necked Avocet
The red-necked avocet (''Recurvirostra novaehollandiae'') also known as the Australian avocet, cobbler, cobbler's awl, and painted lady, is a wader of the family Recurvirostridae that is endemic to Australia and is fairly common and widespread throughout, except for the north and north east coastal areas of the country. Closely related to the stilts, it shares their fragile slender elegance, however the deep red head and neck distinguish them. It appeared on a 13 cent postage stamp in 1966. Taxonomy The French naturalist Louis Jean Pierre Vieillot described the red-necked avocet in 1816, and it still bears its original name. It is one of four species of avocet that make up the genus ''Recurvirostra''. A 2004 study combining genetics and morphology showed that it was the sister taxon to a lineage that gave rise to the Andean and American avocets. Description The distinguishing feature of the red-necked avocet, and all avocet species, is the distinctive upcurved bill that is used ...

American Avocet
The American avocet (''Recurvirostra americana'') is a large wader in the avocet and stilt family, Recurvirostridae, that is found in North America. It spends much of its time foraging in shallow water or on mud flats, often sweeping its bill from side to side in water as it seeks its crustacean and insect prey. Taxonomy The American avocet was formally described in 1789 by the German naturalist Johann Friedrich Gmelin in his revised and expanded edition of Carl Linnaeus's ''Systema Naturae''. He placed it with the pied avocet in the genus ''Recurvirostra'' and coined the binomial name ''Recurvirostra americana''. Gmelin based his description on that by the English ornithologist John Latham who in 1785 had described and illustrated the American avocet in his ''A General Synopsis of Birds''. Latham cited the earlier publication by William Dampier and also that by Thomas Pennant. The genus name combines the Latin meaning 'bent' or 'curved backwards' with meaning 'bill'. The spe ...

Andean Avocet
The Andean avocet (''Recurvirostra andina'') is a large wader in the avocet and stilt bird family, Recurvirostridae. It is resident in the Andes, breeding above 3500 m in northwestern Argentina, western Bolivia, northern Chile and southern Peru. Description This avocet has a white head, neck, underparts and rump, and dark brown back, wings and tail. It is similar in size but slightly bulkier than the American avocet, at in length and in weight. Average body mass is , making it likely the heaviest of the Recurvirostridae family.''CRC Handbook of Avian Body Masses'' by John B. Dunning Jr. (Editor). CRC Press (1992), . The thin, grey legs are not as long as with other avocet species, but the long thin black bill is upturned at the end. The sexes are similar, and the juvenile plumage is undescribed. The colour pattern is similar to that of the local subspecies ''Himantopus himantopus melanurus'' of black-winged stilt, but that bird has very long red legs a white tail and a straight ...

10th Edition Of Systema Naturae
The 10th edition of ''Systema Naturae'' is a book written by Swedish naturalist Carl Linnaeus and published in two volumes in 1758 and 1759, which marks the starting point of zoological nomenclature. In it, Linnaeus introduced binomial nomenclature for animals, something he had already done for plants in his 1753 publication of '' Species Plantarum''. Starting point Before 1758, most biological catalogues had used polynomial names for the taxa included, including earlier editions of ''Systema Naturae''. The first work to consistently apply binomial nomenclature across the animal kingdom was the 10th edition of ''Systema Naturae''. The International Commission on Zoological Nomenclature therefore chose 1 January 1758 as the "starting point" for zoological nomenclature, and asserted that the 10th edition of ''Systema Naturae'' was to be treated as if published on that date. Names published before that date are unavailable, even if they would otherwise satisfy the rules. The only ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Genus
Genus ( plural genera ) is a taxonomic rank used in the biological classification of extant taxon, living and fossil organisms as well as Virus classification#ICTV classification, viruses. In the hierarchy of biological classification, genus comes above species and below family (taxonomy), family. 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 ...

BBC TV
BBC Television is a service of the BBC. The corporation has operated a public broadcast television service in the United Kingdom, under the terms of a royal charter, since 1927. It produced television programmes from its own studios from 1932, although the start of its regular service of television broadcasts is dated to 2 November 1936. The BBC's domestic television channels have no commercial advertising and collectively they accounted for more than 30% of all UK viewing in 2013. The services are funded by a television licence. As a result of the 2016 Licence Fee settlement, the BBC Television division was split, with in-house television production being separated into a new division called BBC Studios and the remaining parts of television (channels and genre commissioning, BBC Sport and BBC iPlayer) being renamed as BBC Content. History of BBC Television The BBC operates several television networks, television stations (although there is generally very little distinct ...

Birdwatcher
Birdwatching, or birding, is the observing of birds, either as a recreational activity or as a form of citizen science. A birdwatcher may observe by using their naked eye, by using a visual enhancement device like binoculars or a telescope, by listening for bird sounds, or by watching public webcams. Most birdwatchers pursue this activity for recreational or social reasons, unlike ornithologists, who engage in the study of birds using formal scientific methods. Birding, birdwatching, and twitching The first recorded use of the term ''birdwatcher'' was in 1901 by Edmund Selous; ''bird'' was introduced as a verb in 1918. The term ''birding'' was also used for the practice of ''fowling'' or hunting with firearms as in Shakespeare's ''The Merry Wives of Windsor'' (1602): "She laments sir... her husband goes this morning a-birding." The terms ''birding'' and ''birdwatching'' are today used by some interchangeably, although some participants prefer ''birding'', partly because it in ...
