Barbthroat
The barbthroats are a genus ''Threnetes'' of South American hummingbirds in the family Trochilidae. Taxonomy The genus ''Threnetes'' was introduced in 1852 by the English ornithologist John Gould. The name is from the Ancient Greek ''thrēnētēs'' meaning "mourner". The type species is the pale-tailed barbthroat. The genus contains three species. The supposed "black barbthroats", described as ''T. grzimeki'', are actually juvenile males of the rufous-breasted hermit The rufous-breasted hermit or hairy hermit (''Glaucis hirsutus'') is a hummingbird that breeds from Panama south to Bolivia, and on Trinidad, Tobago and Grenada.

Sooty Barbthroat
The sooty barbthroat (''Threnetes niger'') is a hummingbird species in the family Trochilidae. It is found in Brazil and French Guiana. Taxonomy The sooty barbthroat was formally described by the Swedish naturalist Carl Linnaeus in 1758 in the tenth edition of his ''Systema Naturae'' under the binomial name ''Trochilus niger''. The type locality is Cayenne in French Guiana. The sooty barbthroat is now placed in the genus '' Threnetes'' that was introduced by John Gould in 1852. Two subspecies are generally recognized:Clements, J. F., T. S. Schulenberg, M. J. Iliff, S. M. Billerman, T. A. Fredericks, J. A. Gerbracht, D. Lepage, B. L. Sullivan, and C. L. Wood. 2021.

Pale-tailed Barbthroat
The pale-tailed barbthroat (''Threnetes leucurus'') is a species of hummingbird in the family Trochilidae. It is found throughout much of the Amazon Basin from the eastern Andean foothills to the Atlantic Ocean. Taxonomy and systematics The pale-tailed barbthroat was formally described by the Swedish naturalist Carl Linnaeus in 1766 in the twelfth edition of his ''Systema Naturae'' under the binomial name ''Trochilus leucurus''. Linnaeus based his short description on the "white-tailed humming-bird" that had been described and illustrated by the English naturalist George Edwards in 1758. The type locality is Suriname. The specific epithet is from the Ancient Greek ''leukouros'' meaning "white-tailed". The pale-tailed barbthroat is now placed in the genus '' Threnetes'' that was introduced in 1852 by the English ornithologist John Gould. Four subspecies are recognised: * ''T. l. cervinicauda'' Gould, 1855 * ''T. l. rufigastra'' Cory, 1915 * ''T. l. leucurus'' (Linnaeus, 1 ...

John Gould
John Gould (; 14 September 1804 – 3 February 1881) was an English ornithologist. He published a number of monographs on birds, illustrated by plates produced by his wife, Elizabeth Gould, and several other artists, including Edward Lear, Henry Constantine Richter, Joseph Wolf and William Matthew Hart. He has been considered the father of bird study in Australia and the Gould League in Australia is named after him. His identification of the birds now nicknamed "Darwin's finches" played a role in the inception of Darwin's theory of evolution by natural selection. Gould's work is referenced in Charles Darwin's book, ''On the Origin of Species''. Early life Gould was born in Lyme Regis, the first son of a gardener. Both father and son probably had little education. After working on Dowager Lady Poulett's glass house, his father obtained a position on an estate near Guildford, Surrey, and then in 1818, Gould Snr became foreman in the Royal Gardens of Windsor. Gould then be ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Carl Linnaeus
Carl Linnaeus (; 23 May 1707 – 10 January 1778), also known after his ennoblement in 1761 as Carl von Linné Blunt (2004), p. 171. (), was a Swedish botanist, zoologist, taxonomist, and physician who formalised binomial nomenclature, the modern system of naming organisms. He is known as the "father of modern taxonomy". Many of his writings were in Latin; his name is rendered in Latin as and, after his 1761 ennoblement, as . Linnaeus was born in Råshult, the countryside of Småland, in southern Sweden. He received most of his higher education at Uppsala University and began giving lectures in botany there in 1730. He lived abroad between 1735 and 1738, where he studied and also published the first edition of his ' in the Netherlands. He then returned to Sweden where he became professor of medicine and botany at Uppsala. In the 1740s, he was sent on several journeys through Sweden to find and classify plants and animals. In the 1750s and 1760s, he continued to collect an ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Species
In biology, a species is the basic unit of classification and a taxonomic rank of an organism, as well as a unit of biodiversity. A species is often defined as the largest group of organisms in which any two individuals of the appropriate sexes or mating types can produce fertile offspring, typically by sexual reproduction. Other ways of defining species include their karyotype, DNA sequence, morphology, behaviour or ecological niche. In addition, paleontologists use the concept of the chronospecies since fossil reproduction cannot be examined. The most recent rigorous estimate for the total number of species of eukaryotes is between 8 and 8.7 million. However, only about 14% of these had been described by 2011. All species (except viruses) are given a two-part name, a "binomial". The first part of a binomial is the genus to which the species belongs. The second part is called the specific name or the specific epithet (in botanical nomenclature, also sometimes i ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Trochilidae
Hummingbirds are birds native to the Americas and comprise the biological family Trochilidae. With about 361 species and 113 genera, they occur from Alaska to Tierra del Fuego, but the vast majority of the species are found in the tropics around the equator. They are small birds, with most species measuring in length. The smallest extant hummingbird species is the bee hummingbird, which weighs less than . The largest hummingbird species is the giant hummingbird, weighing . They are specialized for feeding on flower nectar, but all species also consume flying insects or spiders. Hummingbirds split from their sister group, the swifts and treeswifts, around 42 million years ago. The common ancestor of extant hummingbirds is estimated to have lived 22 million years ago in South America. They are known as hummingbirds because of the humming sound created by their beating wings, which flap at high frequencies audible to humans. They hover in mid-air at rapid wing-flapping rates, ...

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 ...

Ancient Greek
Ancient Greek includes the forms of the Greek language used in ancient Greece and the ancient world from around 1500 BC to 300 BC. It is often roughly divided into the following periods: Mycenaean Greek (), Dark Ages (), the Archaic period (), and the Classical period (). Ancient Greek was the language of Homer and of fifth-century Athenian historians, playwrights, and philosophers. It has contributed many words to English vocabulary and has been a standard subject of study in educational institutions of the Western world since the Renaissance. This article primarily contains information about the Epic and Classical periods of the language. From the Hellenistic period (), Ancient Greek was followed by Koine Greek, which is regarded as a separate historical stage, although its earliest form closely resembles Attic Greek and its latest form approaches Medieval Greek. There were several regional dialects of Ancient Greek, of which Attic Greek developed into Koine. Dia ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
