Bicolored Antvireo
The bicolored antvireo (''Dysithamnus occidentalis'') is an insectivorous bird in the antbird family Thamnophilidae. It is found on the west slope of the Andes from southwest Colombia to northwest Ecuador. Its natural habitat is subtropical or tropical moist montane forests. It is threatened by habitat loss. The bicolored antvireo was described by the American ornithologist Frank Chapman in 1923 who considered it a subspecies of the white-shouldered antshrike (''Thamnophilus aethiops'') and coined the trinomial name ''Thamnophilus aethiops occidentalis''. There are two subspecies: * ''D. o. occidentalis'' (Chapman, 1923) – southwest Colombia and north Ecuador * ''D. o. punctitectus'' Chapman, 1924 – east Ecuador References External linksXeno-canto: audio recordings of the bicolored antvireo |
Frank Chapman (ornithologist)
Frank Michler Chapman (June 12, 1864 – November 15, 1945) was an American ornithologist and pioneering writer of field guides. Biography Chapman was born in West Englewood, New Jersey and attended Englewood Academy. He joined the staff of the American Museum of Natural History in 1888 as assistant to Joel Asaph Allen. In 1901 he was made associate Curator of Mammals and Birds and in 1908 Curator of Birds. Chapman came up with the original idea for the Audubon Christmas Bird Count. He also wrote many ornithological books such as, ''Bird Life'', ''Birds of Eastern North America'', and ''Life in an Air Castle''. Chapman promoted the integration of photography into ornithology, especially in his book ''Bird Studies With a Camera'', in which he discussed the practicability of the photographic blind and in 1901 invented his own more portable version of a blind using an umbrella with a large 'skirt' to conceal the photographer that could be bundled into a small pack for transpor ...

Antbird
The antbirds are a large passerine bird family (biology), family, Thamnophilidae, found across subtropical and tropical Central and South America, from Mexico to Argentina. There are List of antbirds, more than 230 species, known variously as antshrikes, antwrens, antvireos, fire-eyes, bare-eyes and bushbirds. They are related to the antthrushes and antpittas (family Formicariidae), the tapaculos, the gnateaters and the Ovenbird (family), ovenbirds. Despite some species' common names, this family is not closely related to the wrens, vireos or shrikes. Antbirds are generally small birds with rounded wings and strong legs. They have mostly sombre grey, white, brown and rufous plumage, which is sexual dimorphism, sexually dimorphic in pattern and colouring. Some species communicate warnings to rivals by exposing white feather patches on their backs or shoulders. Most have heavy beak, bills, which in many species are hooked at the tip. Most species live in forests, although a few ar ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Andes
The Andes, Andes Mountains or Andean Mountains (; ) are the longest continental mountain range in the world, forming a continuous highland along the western edge of South America. The range is long, wide (widest between 18°S – 20°S latitude), and has an average height of about . The Andes extend from north to south through seven South American countries: Venezuela, Colombia, Ecuador, Peru, Bolivia, Chile, and Argentina. Along their length, the Andes are split into several ranges, separated by intermediate depressions. The Andes are the location of several high plateaus—some of which host major cities such as Quito, Bogotá, Cali, Arequipa, Medellín, Bucaramanga, Sucre, Mérida, El Alto and La Paz. The Altiplano plateau is the world's second-highest after the Tibetan plateau. These ranges are in turn grouped into three major divisions based on climate: the Tropical Andes, the Dry Andes, and the Wet Andes. The Andes Mountains are the highest m ...

Habitat
In ecology, the term habitat summarises the array of resources, physical and biotic factors that are present in an area, such as to support the survival and reproduction of a particular species. A species habitat can be seen as the physical manifestation of its ecological niche. Thus "habitat" is a species-specific term, fundamentally different from concepts such as environment or vegetation assemblages, for which the term "habitat-type" is more appropriate. The physical factors may include (for example): soil, moisture, range of temperature, and light intensity. Biotic factors will include the availability of food and the presence or absence of predators. Every species has particular habitat requirements, with habitat generalist species able to thrive in a wide array of environmental conditions while habitat specialist species requiring a very limited set of factors to survive. The habitat of a species is not necessarily found in a geographical area, it can be the interior ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Montane Forest
Montane ecosystems are found on the slopes of mountains. The alpine climate in these regions strongly affects the ecosystem because temperatures 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, 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 climate becomes cooler, due to a decrease in a ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Habitat Loss
Habitat destruction (also termed habitat loss and habitat reduction) is the process by which a natural habitat becomes incapable of supporting its native species. The organisms that previously inhabited the site are displaced or dead, thereby reducing biodiversity and species abundance. Habitat destruction is the leading cause of biodiversity loss. Fragmentation and loss of habitat have become one of the most important topics of research in ecology as they are major threats to the survival of endangered species. Activities such as harvesting natural resources, industrial production and urbanization are human contributions to habitat destruction. Pressure from agriculture is the principal human cause. Some others include mining, logging, trawling, and urban sprawl. Habitat destruction is currently considered the primary cause of species extinction worldwide. Environmental factors can contribute to habitat destruction more indirectly. Geological processes, climate change, introdu ...

Species Description
A species description is a formal description of a newly discovered species, usually in the form of a scientific paper. Its purpose is to give a clear description of a new species of organism and explain how it differs from species that have been described previously or are related. In order for species to be validly described, they need to follow guidelines established over time. Zoological naming requires adherence to the ICZN code, plants, the ICN, viruses ICTV, and so on. The species description often contains photographs or other illustrations of type material along with a note on where they are deposited. The publication in which the species is described gives the new species a formal scientific name. Some 1.9 million species have been identified and described, out of some 8.7 million that may actually exist. Millions more have become extinct throughout the existence of life on Earth. Naming process A name of a new species becomes valid (available in zo ... [...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 whether ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Trinomial Name
In biology, trinomial nomenclature refers to names for taxa below the rank of species. These names have three parts. The usage is different in zoology and botany. In zoology In zoological nomenclature, a trinomen (), trinominal name, or ternary name refers to the name of a subspecies. Examples are ''Gorilla gorilla gorilla'' ( Savage, 1847) for the western lowland gorilla (genus ''Gorilla'', species western gorilla), and ''Bison bison bison'' (Linnaeus, 1758) for the plains bison (genus '' Bison'', species American bison). A trinomen is a name with three parts: generic name, specific name and subspecific name. The first two parts alone form the binomen or species name. All three names are typeset in italics, and only the first letter of the generic name is capitalised. No indicator of rank is included: in zoology, subspecies is the only rank below that of species. For example: "''Buteo jamaicensis borealis'' is one of the subspecies of the red-tailed hawk (''Buteo jamaicensis ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Dysithamnus
''Dysithamnus'' is a genus of insectivorous passerine birds in the antbird family, Thamnophilidae. Species in this genus are known as antvireos. The genus ''Dysithamnus'' was introduced by the German ornithologist Jean Cabanis in 1847. The name combines the Ancient Greek words ''duō'' "to plunge" and ''thamnos'' "bush". The type species was subsequently designated as the spot-breasted antvireo. The genus contains the following eight species: * Spot-breasted antvireo, ''Dysithamnus stictothorax'' * Plain antvireo, ''Dysithamnus mentalis'' * Streak-crowned antvireo, ''Dysithamnus striaticeps'' * Spot-crowned antvireo, ''Dysithamnus puncticeps'' * Rufous-backed antvireo, ''Dysithamnus xanthopterus'' * White-streaked antvireo, ''Dysithamnus leucostictus'' * Plumbeous antvireo, ''Dysithamnus plumbeus'' * Bicolored antvireo The bicolored antvireo (''Dysithamnus occidentalis'') is an insectivorous bird in the antbird family Thamnophilidae.

Birds Of The Colombian 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. Bird ...
