Scaled Pigeon
The scaled pigeon (''Patagioenas speciosa'') is a large New World tropical dove. It is a resident breeder from southern Mexico south to western Ecuador, southern Brazil, northern Argentina, and Trinidad. The scaled pigeon is fairly common in semi-open forest. It builds a stick platform nest in a tree and lays two white eggs. Its flight is high, fast and direct, with the regular beats and an occasional sharp flick of the wings which are characteristic of pigeons in general. It is usually very wary, since it is frequently hunted. Taxonomy The scaled pigeon was formally described in 1789 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 doves and pigeons in the genus '' Columba'' and coined the binomial name ''Columba speciosa''. Gmelin based his description on "Le Ramiret" and the "Pigeon ramier de Cayenne" that had been described and illustrated in 1871 by the French po ...

Ludwig Reichenbach
Heinrich Gottlieb Ludwig Reichenbach (8 January 1793 – 17 March 1879) was a German botanist and ornithologist. It was he who first requested Leopold Blaschka to make a set of glass marine invertebrate models for scientific education and museum showcasing, the successful commission giving rise to the creation of the Blaschkas' Glass sea creatures and, subsequently and indirectly, the more famous Glass Flowers. Early life Born in Leipzig and the son of Johann Friedrich Jakob Reichenbach (the author in 1818 of the first Greek-German dictionary) Reichenbach studied medicine and natural science at the University of Leipzig in 1810 and, eight years later in 1818, he the now Professor became an instructor before, in 1820, he was appointed the director of the Dresden natural history museum and a professor at the Surgical-Medical Academy in Dresden, where he remained for many years.

Birds Of Colombia
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] |

Helm Identification Guides
The ''Helm Identification Guides'' are a series of books that identify groups of birds. The series include two types of guides, those that are: * Taxonomic, dealing with a particular family of birds on a worldwide scale—most early Helm Guides were this type, as well as many more-recent ones, although some later books deal with identification of such groups on a regional scale only (e.g., ''The Gulls Guide,'' which covers only species in Europe, Asia, and North America) * Geographic, including all bird species in an area (e.g., ''The Birds of the West Indies'') Early volumes were sometimes published under the Croom Helm or Christopher Helm imprints. In addition, a parallel set of guides, very similar in design, was published by Pica Press in the 1990s (marked ''Pica'' in the list below); Pica was later absorbed into A & C Black (now part of Bloomsbury Publishing Plc), and all guides are now marketed as a single series. Several of the books have won the British Birds ''Bird B ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Pearl Kite
The pearl kite (''Gampsonyx swainsonii'') is a very small raptor found in open savanna habitat adjacent to deciduous woodland. It is the only member of the genus ''Gampsonyx''. The scientific name commemorates the English naturalist William Swainson. Taxonomy and systematics The type specimen was collected from Brazil by English naturalist William Swainson, and described by Nicholas Aylward Vigors in 1825. Vigors noted the similarity to both hawks and falcons, but placed ''Gampsonyx'' within the "Accipitrine subfamily" because it lacks the notched beak of the falcons. He also noted its striking resemblance to the coloration of the falconets. Later, the pearl kite was classified with the falcons. For example, Peters placed it with the forest falcons in subfamily Polyhieracinae. In the mid-20th century it was found to be related to '' Elanus'' based on morphology and its molt schedule. Distribution and habitat This tiny kite breeds from Panama, Colombia and Venezuela south to Bo ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Cyathea Cyatheoides
''Cyathea'' is a genus of tree ferns, the type genus of the fern order Cyatheales. The genus name ''Cyathea'' is derived from the Greek ''kyatheion'', meaning "little cup", and refers to the cup-shaped sori on the underside of the fronds. Description The species of ''Cyathea'' are mostly terrestrial ferns, usually with a single tall stem. Rarely, the trunk may be branched or creeping. Many species also develop a fibrous mass of roots at the base of the trunk. The genus has a pantropical distribution, with over 470 species. They grow in habitats ranging from tropical rain forests to temperate woodlands. Classification Conant ''et al.'' in 1996, concluded on molecular cpDNA and morphological evidence that a system of three clades – ''Alsophila'', ''Cyathea'' and ''Sphaeropteris'' was the most accurate reflection of evolutionary lineages within the Cyatheaceae, ''Alsophila'' being the most basal and ''Cyathea'' and ''Sphaeropteris'' derived sister groups.

Pteridium Aquilinum
''Pteridium aquilinum'' (bracken, brake or common bracken), also known as eagle fern, is a species of fern occurring in temperate and subtropical regions in both hemispheres. Originally native to Eurasia and North America, the extreme lightness of its spores has led to it achieving a cosmopolitan distribution. Etymology Common bracken was first described as ''Pteris aquilina'' by Carl Linnaeus, in Volume 2 of his ''Species Plantarum'' in 1753. The origin of the specific epithet derived from the Latin ''aquila'' "eagle". In the reprint of the ''Flora Suecica'' in 1755, Linnaeus explains that the name refers to the image of an eagle seen in the transverse section of the root. In spite of this, the opinion has been forwarded that the name pertains to the shape of the mature fronds appearing akin to an eagle's wing. However, medieval scholars, including Erasmus, thought the pattern of the fibres seen in a transverse section of the stipe resembled a double-headed eagle or oak tree. Ta ...

White-crowned Pigeon
The white-crowned pigeon (''Patagioenas leucocephala'') is a fruit and seed-eating species of bird in the dove and pigeon family Columbidae. It is found primarily in the Caribbean. John James Audubon painted these pigeons, including the watercolour painting in his work, '' Birds of America'', published in the early 19th century. Taxonomy In the first half of the 18th century the white-crowned pigeon was described and illustrated by several naturalists including John Ray in 1713, Hans Sloane in 1725 and Mark Catesby in 1731. When in 1758 the Swedish naturalist Carl Linnaeus updated his ''Systema Naturae'' for the tenth edition, he placed the white-crowned pigeon with all the other pigeons in the genus ''Columba''. Linnaeus included a brief description, coined the binomial name ''Columba leucocephala'' and cited the earlier authors. The specific epithet combines the Ancient Greek ''leukos'' meaning "white" and ''-kephalos'' meaning "-headed". Although Linnaeus gave the location a ...

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