Tit-like Dacnis
The tit-like dacnis (''Xenodacnis parina'') is a small neotropical passerine bird found in southern Ecuador and Peru. In Spanish, it is known as ''Azulito Altoandino''. It is found in Andean montane scrub forests from 3000 m to 4600 m elevation. Adults reach 12.5 cm in length. Males are solid deep blue with dark eyes, bill, and feet. Females of all subspecies are duller, with rufous-brown underparts. Taxonomy The tit-like dacnis was formally described in 1873 by the German ornithologist Jean Cabanis from a specimen collected in the Andes of central Peru. Cabanis introduced the genus ''Xenodacnis'' and coined the binomial name ''Xenodacnis parina''. The genus name combines the Ancient Greek ''xenos '' meaning "different" or "unusual" with the genus name ''Dacnis''. The specific epithet ''parina'' is from Modern Latin and means "tit like". The tit-like dacnis is sister to a clade containing the four species now placed in the genus ''Idiopsar''. Three subspecies a ...

Jean Cabanis
Jean Louis Cabanis (8 March 1816 – 20 February 1906) was a German ornithologist. Cabanis was born in Berlin to an old Huguenot family who had moved from France. Little is known of his early life. He studied at the University of Berlin from 1835 to 1839, and then travelled to North America, returning in 1841 with a large natural history collection. He was assistant and later director of the Natural History Museum of Berlin (which was at the time the Berlin University Museum), taking over from Martin Lichtenstein. He founded the '' Journal für Ornithologie'' in 1853, editing it for the next forty-one years, when he was succeeded by his son-in-law Anton Reichenow. He died in Friedrichshagen. A number of birds are named after him, including Cabanis's bunting ''Emberiza cabanisi'', Cabanis's spinetail ''Synallaxis cabanisi'', Azure-rumped tanager ''Poecilostreptus cabanisi'' and Cabanis's greenbul Cabanis's greenbul (''Phyllastrephus cabanisi''), also known as Cabanis's bulb ...

Sister Taxon
In phylogenetics, a sister group or sister taxon, also called an adelphotaxon, comprises the closest relative(s) of another given unit in an evolutionary tree. Definition The expression is most easily illustrated by a cladogram: Taxon A and taxon B are sister groups to each other. Taxa A and B, together with any other extant or extinct descendants of their most recent common ancestor (MRCA), form a monophyletic group, the clade AB. Clade AB and taxon C are also sister groups. Taxa A, B, and C, together with all other descendants of their MRCA form the clade ABC. The whole clade ABC is itself a subtree of a larger tree which offers yet more sister group relationships, both among the leaves and among larger, more deeply rooted clades. The tree structure shown connects through its root to the rest of the universal tree of life. In cladistic standards, taxa A, B, and C may represent specimens, species, genera, or any other taxonomic units. If A and B are at the same t ...

Birds Of The Peruvian Andes
Birds are a group of warm-blooded vertebrates constituting the class Aves (), characterised by feathers, toothless beaked jaws, the laying of hard-shelled eggs, a high metabolic rate, a four-chambered heart, and a strong yet lightweight skeleton. Birds live worldwide and range in size from the bee hummingbird to the ostrich. There are about ten thousand living species, more than half of which are passerine, or "perching" birds. Birds have whose development varies according to species; the only known groups without wings are the extinct moa and elephant birds. Wings, which are modified forelimbs, gave birds the ability to fly, although further evolution has led to the loss of flight in some birds, including ratites, penguins, and diverse endemic island species. The digestive and respiratory systems of birds are also uniquely adapted for flight. Some bird species of aquatic environments, particularly seabirds and some waterbirds, have further evolved for swimming ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Thraupidae
The tanagers (singular ) comprise the bird family Thraupidae, in the order Passeriformes. The family has a Neotropical distribution and is the second-largest family of birds. It represents about 4% of all avian species and 12% of the Neotropical birds. Traditionally, the family contained around 240 species of mostly brightly colored fruit-eating birds. As more of these birds were studied using modern molecular techniques, it became apparent that the traditional families were not monophyletic. '' Euphonia'' and '' Chlorophonia'', which were once considered part of the tanager family, are now treated as members of the Fringillidae, in their own subfamily ( Euphoniinae). Likewise, the genera '' Piranga'' (which includes the scarlet tanager, summer tanager, and western tanager), ''Chlorothraupis'', and '' Habia'' appear to be members of the cardinal family, and have been reassigned to that family by the American Ornithological Society.

Rodolphe Meyer De Schauensee
Rodolphe Meyer de Schauensee (January 4, 1901 – April 24, 1984) was an American ornithologist. He was born in Rome, Italy to a Swiss aristocratic family. His family moved to the United States in 1913. He was the curator of ornithology at the Academy of Natural Sciences in Philadelphia for nearly fifty years. He was particularly noted for his study of South American birds. He expanded the academy's collection of bird skins, taking part in collecting trips to Brazil, Thailand, Burma, southern Africa, the East Indies The East Indies (or simply the Indies), is a term used in historical narratives of the Age of Discovery. The Indies refers to various lands in the East or the Eastern hemisphere, particularly the islands and mainlands found in and aroun ..., and Guatemala. He wrote about the birds of South America, including the groundbreaking ''A Guide to the Birds of South America'' in 1970, and published a book on the birds of China just two weeks before his death.

James Bond (ornithologist)
James Bond (January 4, 1900 – February 14, 1989) was an American ornithologist and expert on the birds of the Caribbean, having written the definitive book on the subject: '' Birds of the West Indies'', first published in 1936. He served as a curator of the Academy of Natural Sciences of Philadelphia. His name was appropriated by writer Ian Fleming for his fictional British spy of the same name; the real Bond enjoyed knowing his name was being used this way, and references to him permeate the resulting media franchise. Life and career Bond was born on January 4, 1900, in Philadelphia, Pennsylvania, the son of Margaret Reeves ( Tyson) and Francis Edward Bond. His interest in natural history was spurred by an expedition his father undertook in 1911 to the Orinoco Delta. Bond was educated at the Delancey School followed by St. Paul's School in Concord, New Hampshire, but after the death of his mother he moved with his father to the United Kingdom in 1914. There, he studied at ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Subspecies
In biological classification, subspecies is a rank below species, used for populations that live in different areas and vary in size, shape, or other physical characteristics ( morphology), but that can successfully interbreed. Not all species have subspecies, but for those that do there must be at least two. Subspecies is abbreviated subsp. or ssp. and the singular and plural forms are the same ("the subspecies is" or "the subspecies are"). In zoology, under the International Code of Zoological Nomenclature, the subspecies is the only taxonomic rank below that of species that can receive a name. In botany and mycology, under the International Code of Nomenclature for algae, fungi, and plants, other infraspecific ranks, such as variety, may be named. In bacteriology and virology, under standard bacterial nomenclature and virus nomenclature, there are recommendations but not strict requirements for recognizing other important infraspecific ranks. A taxonomist decides w ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Idiopsar
''Idiopsar'' is a genus of Neotropical seed-eating birds in the tanager family Thraupidae. Taxonomy and species list The genus ''Idiopsar'' was introduced in 1867 by the American ornithologist John Cassin to accommodate the newly described boulder finch. The name combines the Ancient Greek ''idios'' meaning "distinct" or "peculiar" with ''psar'' meaning "starling". This genus formerly contained a single species, the boulder finch. A molecular phylogenetic study of the tanager family (Thraupidae) published in 2014 found that the boulder finch was a member of a clade that contained three species assigned to other genera. In the ensuing reorganization of generic boundaries, these three species were assigned to ''Idiopsar''. The same genetic study found that ''Idiopsar'' is sister to the tit-like dacnis in the monospecific genus ''Xenodacnis''. The genus contains four species. * Red-backed sierra finch, ''Idiopsar dorsalis'' (formerly assigned to '' Phrygilus''; alternatively ...

Clade
A clade (), also known as a monophyletic group or natural group, is a group of organisms that are monophyletic – that is, composed of a common ancestor and all its lineal descendants – on a phylogenetic tree. Rather than the English term, the equivalent Latin term ''cladus'' (plural ''cladi'') is often used in taxonomical literature. The common ancestor may be an individual, a population, or a species (extinct or 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 taxa that are not clades; that is, taxa that are not monophyletic. Some of the relationships between org ...

Modern Latin
New Latin (also called Neo-Latin or Modern Latin) is the revival of Literary Latin used in original, scholarly, and scientific works since about 1500. Modern scholarly and technical nomenclature, such as in zoological and botanical taxonomy and international scientific vocabulary, draws extensively from New Latin vocabulary, often in the form of classical or neoclassical compounds. New Latin includes extensive new word formation. As a language for full expression in prose or poetry, however, it is often distinguished from its successor, Contemporary Latin. Extent Classicists use the term "Neo-Latin" to describe the Latin that developed in Renaissance Italy as a result of renewed interest in classical civilization in the 14th and 15th centuries. Neo-Latin also describes the use of the Latin language for any purpose, scientific or literary, during and after the Renaissance. The beginning of the period cannot be precisely identified; however, the spread of secular education, ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Passerine
A passerine () is any bird of the order Passeriformes (; from Latin 'sparrow' and '-shaped'), which includes more than half of all bird species. Sometimes known as perching birds, passerines are distinguished from other orders of birds by the arrangement of their toes (three pointing forward and one back), which facilitates perching. With more than 140 families and some 6,500 identified species, Passeriformes is the largest clade of birds and among the most diverse clades of terrestrial vertebrates, representing 60% of birds.Ericson, P.G.P. et al. (2003Evolution, biogeography, and patterns of diversification in passerine birds ''J. Avian Biol'', 34:3–15.Selvatti, A.P. et al. (2015"A Paleogene origin for crown passerines and the diversification of the Oscines in the New World" ''Molecular Phylogenetics and Evolution'', 88:1–15.

Dacnis
''Dacnis'' is a genus of Neotropical birds in the tanager family Thraupidae. These are highly sexually dichromatic species with bright blue males and green females. They have various bill types and many of them feed on nectar. Taxonomy and species list The genus ''Dacnis'' was introduced in 1816 by the French naturalist Georges Cuvier with the blue dacnis as the type species. The name is from the Ancient Greek ''daknis'', an unidentified bird from Egypt listed by Hesychius of Alexandria and Sextus Pompeius Festus. This genus is placed together with the genera ''Tesina'' and ''Cyanerpes'' in the subfamily In biological classification, a subfamily (Latin: ', plural ') is an auxiliary (intermediate) taxonomic rank, next below family but more inclusive than genus. Standard nomenclature rules end subfamily botanical names with "-oideae", and zoologi ... Dacninae. The genus contains ten species: References Bird genera Taxa named by Georges Cuvier {{Thraup ...
