Ruby-crowned Kinglet
The ruby-crowned kinglet (''Corthylio calendula'') is a very small passerine bird found throughout North America. It is a member of the kinglet family. The bird has olive-green plumage with two white wing bars and a white eye-ring. Males have a red crown patch, which is often concealed. The sexes are identical apart from the crown, and juveniles are similar in plumage to adult females. It is one of the smallest songbirds in North America. The ruby-crowned kinglet is not closely related to other kinglets and was moved from ''Regulus (bird), Regulus'' to its own genus, ''Corthylio'' in 2021. Three subspecies are currently recognized. The kinglet is mostly migratory, and its range extends from northwest Canada and Alaska south to Mexico. Its breeding habitat is spruce-fir forests in the northern and mountainous regions of the United States and Canada. The ruby-crowned kinglet builds a cup-shaped bird nest, nest, which may be pensile or placed on a tree branch and is often hidden. It ...

Jean Cabanis
Jean Louis Cabanis (8 March 1816 – 20 February 1906) was a German ornithologist. He worked at the bird collections of the Natural History Museum in Berlin becoming its first curator of birds in 1850. He founded the ''Journal für Ornithologie'' in 1853''.'' Biography Cabanis was born in Berlin to an old Huguenot family who had moved from France. His father Benoit-Jean (1774–1838) and mother Maria Luise (1783–1849) both came from families that were in the textile industry. Little is known of his early life. He studied at the University of Berlin from 1835 to 1839, and then travelled to North America, working as a museum assistant in Carolina. He returned in 1841 with a large natural history collection. He was assistant at the Natural History Museum, Berlin, Natural History Museum of Berlin (which was at the time the Berlin University Museum) and in 1850 he became the curator of birds, taking over from Martin Lichtenstein. Charles Lucien Bonaparte had offered him a positio ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
William Bartram
William Bartram (April 20, 1739 – July 22, 1823) was an American naturalist, writer and explorer. Bartram was the author of an acclaimed book, now known by the shortened title Bartram's ''Travels'', which chronicled his explorations of the Southern Colonies of British North America from 1773 to 1777. Bartram has been described as "the first naturalist who penetrated the dense tropical forests of Florida". Bartram was one of the first ornithologists born in America. In 1756, at the age of 17, he collected the type specimens of 14 species of American birds, which were illustrated and described by the English naturalist George Edwards in ''Gleanings of Natural History'' vol. 2 (1760). These accounts formed the basis of the scientific descriptions of Linnaeus (1707–1778), Johann Friedrich Gmelin (1748–1804) and John Latham (1740–1837). Bartram also made significant contributions to botanical literature. Like his father, he was a member of the American Philosophical Societ ...

Montane Ecosystems
Montane ecosystems are found on the slopes of mountains. The alpine climate in these regions strongly affects the ecosystem because temperatures lapse rate, fall as elevation increases, causing the ecosystem to stratify. This stratification is a crucial factor in shaping plant community, biodiversity, metabolic processes and ecosystem dynamics for montane ecosystems. Dense montane forests are common at moderate elevations, due to moderate temperatures and high rainfall. At higher elevations, the climate is harsher, with lower temperatures and higher winds, preventing the growth of trees and causing the plant community to transition to montane grasslands and shrublands or alpine tundra. Due to the unique climate conditions of montane ecosystems, they contain increased numbers of endemic species. Montane ecosystems also exhibit variation in ecosystem services, which include carbon storage and water supply. Life zones As elevation increases, the alpine climate, climate becomes co ...

Miocene
The Miocene ( ) is the first epoch (geology), geological epoch of the Neogene Period and extends from about (Ma). The Miocene was named by Scottish geologist Charles Lyell; the name comes from the Greek words (', "less") and (', "new") and means "less recent" because it has 18% fewer modern marine invertebrates than the Pliocene has. The Miocene followed the Oligocene and preceded the Pliocene. As Earth went from the Oligocene through the Miocene and into the Pliocene, the climate slowly cooled towards a series of ice ages. The Miocene boundaries are not marked by distinct global events but by regionally defined transitions from the warmer Oligocene to the cooler Pliocene Epoch. During the Early Miocene, Afro-Arabia collided with Eurasia, severing the connection between the Mediterranean and Indian Oceans, and allowing the interchange of fauna between Eurasia and Africa, including the dispersal of proboscideans and Ape, hominoids into Eurasia. During the late Miocene, the conn ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Hesychius Of Alexandria
Hesychius of Alexandria () was a Greek grammarian who, probably in the 5th or 6th century AD, compiled the richest lexicon of unusual and obscure Greek words that has survived, probably by absorbing the works of earlier lexicographers. The work, titled "Alphabetical Collection of All Words" (, ''Synagōgē Pasōn Lexeōn kata Stoicheion''), includes more than 50,000 entries, a copious list of peculiar words, forms and phrases, with an explanation of their meaning, and often with a reference to the author who used them or to the district of Greece where they were current. Hence, the book is of great value to the student of the Ancient Greek dialects and in the restoration of the text of the classical authors generallyparticularly of such writers as Aeschylus and Theocritus, who used many unusual words. Hesychius is important, not only for Greek philology, but also for studying lost languages and obscure dialects of the Balkans in antiquity (such as Albanoid and Thracian) and i ...

Ancient Greek
Ancient Greek (, ; ) includes the forms of the Greek language used in ancient Greece and the classical antiquity, ancient world from around 1500 BC to 300 BC. It is often roughly divided into the following periods: Mycenaean Greek (), Greek Dark Ages, Dark Ages (), the Archaic Greece, Archaic or Homeric Greek, Homeric period (), and the Classical Greece, Classical period (). Ancient Greek was the language of Homer and of fifth-century Athens, fifth-century Athenian historians, playwrights, and Ancient Greek philosophy, 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 Homeric Greek, Epic and Classical periods of the language, which are the best-attested periods and considered most typical of Ancient Greek. From the Hellenistic period (), Ancient Greek was followed by Koine Greek, which is regar ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Regulus (bird)
''Regulus'' is a genus of bird in the family Regulidae. It contains most kinglet species aside from the ruby-crowned kinglet (''Corthylio calendula''), which was formerly classified in ''Regulus'' but is now known to belong to its own genus. Taxonomy The name of the genus is derived from the Latin ''regulus'', a diminutive of ''rex'', "a king", and refers to the characteristic orange or yellow crests of adult kinglets. Several forms have only recently had their status clarified. The Madeira firecrest was formerly considered to be a subspecies, ''R. i. madeirensis'', of the common firecrest ''R. ignicapillus''. A phylogenetic analysis based on the cytochrome b gene showed that the Madeiran form is distinct at the species level from the firecrest nominate subspecies ''R. i. ignicapillus''. Cytochrome ''b'' gene divergence between the Madeira firecrest and the European bird is 8.5%, comparable with the divergence level between other recognised ''Regulus'' species, such as the 9% ...

Old World Warbler
The Old World warblers are a large group of birds formerly grouped together in the bird family Sylviidae. They are not closely related to the New World warblers. The family held over 400 species in over 70 genera, and were the source of much taxonomic confusion. Two families were split out initially, the cisticolas into Cisticolidae and the kinglets into Regulidae. In the past 20–30 years they have been the subject of much research and many species are now placed into other families, including the Acrocephalidae, Cettiidae, Phylloscopidae, and Megaluridae. In addition some species have been moved into existing families or have not yet had their placement fully resolved. Only a small number of warblers, in just two genera, are now retained in the family Sylviidae. Characteristics Most Old World warblers are of generally undistinguished appearance, though some species are boldly marked. The sexes are often identical, but may be clearly distinct, notably in the genera '' ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Type Locality (biology)
In biology, a type is a particular wikt:en:specimen, specimen (or in some cases a group of specimens) of an organism to which the scientific name of that organism is formally associated. In other words, a type is an example that serves to anchor or centralizes the defining features of that particular taxon. In older usage (pre-1900 in botany), a type was a taxon rather than a specimen. A taxon is a scientifically named grouping of organisms with other like organisms, a set (mathematics), set that includes some organisms and excludes others, based on a detailed published description (for example a species description) and on the provision of type material, which is usually available to scientists for examination in a major museum research collection, or similar institution. Type specimen According to a precise set of rules laid down in the International Code of Zoological Nomenclature (ICZN) and the ''International Code of Nomenclature for algae, fungi, and plants'' (ICN), the ...
