Discosura
''Discosura'' is a genus of hummingbird in the family Trochilidae. The thorntails are sometimes placed in the genus ''Popelairia'' (Reichenbach, 1854), leaving ''Discosura'' for the racket-tailed coquette. On the contrary, some have argued for merging this genus into '' Lophornis'', which they overall resemble, except for the highly modified tail-feathers of the males. Taxonomy The genus ''Discosura'' was introduced in 1850 by the French naturalist Charles Lucien Bonaparte. Bonaparte did not specify a type species but this was designated as the racket-tailed coquette by George Robert Gray in 1855. The genus name combines the 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.

Racket-tailed Coquette
The racket-tailed coquette (''Discosura longicaudus''; sometimes ''Discosura longicauda'') is a species of hummingbird in the family Trochilidae native to northern South America. Taxonomy The racket-tailed coquette was formally described in 1788 by the German naturalist Johann Friedrich Gmelin in his revised and expanded edition of Carl Linnaeus's ''Systema Naturae''. He placed it with all the other hummingbirds in the genus ''Trochilus'' and coined the binomial name ''Trochilus longicaudus''. Gmelin based his description on the "L'oiseau-mouche à raquettes" that had been described by the French polymath Georges-Louis Leclerc, Comte de Buffon in 1779 in his ''Histoire Naturelle des Oiseaux''. Buffon did not specify the origin of his specimen but in 1902 Hans von Berlepsch and Ernst Hartert designated the type locality as Cayenne, French Guiana. The racket-tailed coquette is now placed with four other hummingbirds in the genus ''Discosura'' that was introduced in 1850 by the Fre ...

Some authors have further merged ''Discosura'' into ''Lophornis'' but this treatment has not been widely accepted. Though early authors proposed two subspecies for the green thorntail, current taxonomies treat it as monotypic.Clements, J. F., T. S. Schulenberg, M. J. Iliff, S. M. Billerman, T. ...

Localities for old skins often are unreliable, and it is possible they came from elsewhere. Consequently, its behavior and habitat are unknown but are likely similar to those of other thorntails. It has been suggested that it represented a hybrid or a variant of the racquet-tailed coquette, but a study by G.R. Graves has validated its status as a distinct species.

Hummingbirds split from their Sister taxon, sister group, the Swift (bird), 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.

Green Thorntail JCB
Green is the color between cyan and yellow on the visible spectrum. It is evoked by light which has a dominant wavelength of roughly 495570 nm. In subtractive color systems, used in painting and color printing, it is created by a combination of yellow and cyan; in the RGB color model, used on television and computer screens, it is one of the additive primary colors, along with red and blue, which are mixed in different combinations to create all other colors. By far the largest contributor to green in nature is chlorophyll, the chemical by which plants photosynthesize and convert sunlight into chemical energy. Many creatures have adapted to their green environments by taking on a green hue themselves as camouflage. Several minerals have a green color, including the emerald, which is colored green by its chromium content. During post-classical and early modern Europe, green was the color commonly associated with wealth, merchants, bankers, and the gentry, while red was r ...

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 Koi ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
