Phaethornis Aethopyga
'' Phaethornis '' is a genus of hummingbirds in the hermit subfamily, Phaethornithinae. They occur from southern Mexico, through Central America, to South America as far south as northern Argentina. Description and ecology Their plumage typically involves greens, browns, rufous or grey. Most species show some green or bronze iridescence to the upperparts, but this is far less conspicuous than that of many other hummingbirds. The male and female plumages of hermits are very similar, with differences limited to details of bill-shape, tail-shape and/or strength of colours/patterns. No species of hermit show the strong sexual dimorphism usually associated with hummingbirds. ''Phaethornis'' hermits typically have a long decurved bill, although three species, ''P. koepkeae'', ''P. philippii'' and ''P. bourcieri'' have virtually straight bills. They have a red or yellow base to the lower mandible, and their two central tail feathers are elongated and tipped with white, buff or ochr ...

Phaethornis Superciliosus
The long-tailed hermit (''Phaethornis superciliosus'') is a large hummingbird that is a resident breeder in Venezuela, the Guianas, and north-eastern Brazil. This species was formerly referred to as the eastern long-tailed hermit. Taxonomy The long-tailed hermit was formally described by the Swedish naturalist Carl Linnaeus in 1766 in the twelfth edition of his ''Systema Naturae'' under the binomial name ''Trochilus superciliosus''. Linnaeus based his description on the "colibry à longue queue de Cayenne" that had been described and illustrated in 1760 by the French zoologist Mathurin Jacques Brisson. The specific epithet is from Latin ''superciliosa'' meaning "eye-browed". The long-tailed hermit is now the type species of the genus ''Phaethornis'' that was introduced in 1827 by William Swainson. Two subspecies are recognised: * ''P. s. superciliosus'' (Linnaeus, 1766) – south Venezuela, the Guianas and north Brazil (north of the Amazon) * ''P. s. muelleri'' Hellmayr, 1911 â ...

The flight-feathers and tail are blackish; the latter tipped whitish to ochraceous depending on the subspecies involved. As in most other hermits, it has a long, decurved bill. The basal half of the lower mandible is yellow, but otherwise the entire bill is black. The sexes ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Black-throated Hermit
The black-throated hermit (''Phaethornis atrimentalis'') is a species of hummingbird in the family Trochilidae. It is found in Colombia, Ecuador, and Peru. Taxonomy and systematics The black-throated hermit was for a time considered a subspecies of little hermit (''P. longuemareus''), but is more closely related to the reddish hermit (''P. ruber'') and grey-chinned hermit (''P. griseogularis'').

Taxonomy (biology)
In biology, taxonomy () is the scientific study of naming, defining ( circumscribing) and classifying groups of biological organisms based on shared characteristics. Organisms are grouped into taxa (singular: taxon) and these groups are given a taxonomic rank; groups of a given rank can be aggregated to form a more inclusive group of higher rank, thus creating a taxonomic hierarchy. The principal ranks in modern use are domain, kingdom, phylum (''division'' is sometimes used in botany in place of ''phylum''), class, order, family, genus, and species. The Swedish botanist Carl Linnaeus is regarded as the founder of the current system of taxonomy, as he developed a ranked system known as Linnaean taxonomy for categorizing organisms and binomial nomenclature for naming organisms. With advances in the theory, data and analytical technology of biological systematics, the Linnaean system has transformed into a system of modern biological classification intended to reflect the evolu ...

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] |
Type Species
In zoological nomenclature, a type species (''species typica'') is the species name with which the name of a genus or subgenus is considered to be permanently taxonomically associated, i.e., the species that contains the biological type specimen(s). Article 67.1 A similar concept is used for suprageneric groups and called a type genus. In botanical nomenclature, these terms have no formal standing under the code of nomenclature, but are sometimes borrowed from zoological nomenclature. In botany, the type of a genus name is a specimen (or, rarely, an illustration) which is also the type of a species name. The species name that has that type can also be referred to as the type of the genus name. Names of genus and family ranks, the various subdivisions of those ranks, and some higher-rank names based on genus names, have such types.

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 ...

Arthropods
Arthropods (, (gen. ποδός)) are invertebrate animals with an exoskeleton, a Segmentation (biology), segmented body, and paired jointed appendages. Arthropods form the phylum Arthropoda. They are distinguished by their jointed limbs and Arthropod cuticle, cuticle made of chitin, often Mineralization (biology), mineralised with calcium carbonate. The arthropod body plan consists of segments, each with a pair of appendages. Arthropods are bilaterally symmetrical and their body possesses an exoskeleton, external skeleton. In order to keep growing, they must go through stages of moulting, a process by which they shed their exoskeleton to reveal a new one. Some species have wings. They are an extremely diverse group, with up to 10 million species. The haemocoel, an arthropod's internal cavity, through which its haemolymph – analogue of blood – circulates, accommodates its interior Organ (anatomy), organs; it has an open circulatory system. Like their exteriors, the internal or ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Costus
''Costus'' is a group of herbaceous perennial plants in the family Costaceae, described by Linnaeus as a genus in 1753. It was formerly known as ''Hellenia'' after the Finnish botanist Carl Niclas von Hellens. It is widespread through tropical and subtropical regions of Asia, Africa, and the Americas. ''Costus'' is often characterized and distinguished from relatives such as ''Zingiber'' (true ginger) by its spiraling stems. The genus as a whole is thus often called spiral gingers, but this can also refer to '' C. barbatus'' specifically. '' Costus spectabilis'' is the floral emblem of Nigeria; its flowers are represented (erroneously in red instead of yellow color) on its coat of arms. It is important not to confuse ''Costus speciosus'', ''C. spectabilis'' etc. with the herb known by the common name " costus". Some species are of importance to herbivores, such as caterpillars of the restricted demon (''Notocrypta curvifascia'') which feed on '' Costus speciosus'' (crê ...

Passiflora
''Passiflora'', known also as the passion flowers or passion vines, is a genus of about 550 species of flowering plants, the type genus of the family Passifloraceae. They are mostly tendril-bearing vines, with some being shrubs or trees. They can be woody or herbaceous. Passion flowers produce regular and usually showy flowers with a distinctive corona. There can be as many as eight coronal series, as in the case of ''P. xiikzodz''. The flower is pentamerous and ripens into an indehiscent fruit with numerous seeds. List of species Distribution ''Passiflora'' has a largely neotropic distribution, unlike other genera in the family Passifloraceae, which includes more Old World species (such as the genus ''Adenia''). The vast majority of ''Passiflora'' are found in Mexico, Central America, the United States and South America, although there are additional representatives in Southeast Asia and Oceania. New species continue to be identified: for example, '' P. xishuangbannaensis ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
