Green-and-black Fruiteater
The green-and-black fruiteater (''Pipreola riefferii'') is a species of bird in the family Cotingidae. It is found in Colombia, Ecuador, Peru, and Venezuela, where its habitat is subtropical or tropical moist montane forests. Because of its range and population size this species is not classified as threatened. Description The green-and-black fruiteater is a plump, stocky bird with a length of about . The adult male has a black head, throat and chest glossed with green and mid-green upper parts, with pale tips to the tertial feathers of the wings. There is a yellow rim to the dark chest and the underparts are otherwise yellowish, usually mottled or streaked with green. The female is similar to the male apart from the replacement of the black areas by green, and the absence of the yellow necklace. In both sexes, the iris of the eye is reddish-brown, and the legs and bill are orangish-red. The song is a high-pitched "ts-s-s-s-s-s-s" lasting for a few seconds, slowing and sometime ...

Auguste Boissonneau
Auguste Boissonneau (26 July 1802, Saumur – 7 July 1883, Paris) was a French ornithologist and ocularist. In the latter field he was a pioneer of ocular prosthesis. As an ornithologist, he was the taxonomic authority of numerous species native to tropical and subtropical South America. The hummingbird genus ''Boissonneaua'' (Reichenbach, 1854) commemorates his name, as does the species '' Pseudocolaptes boissonneautii'' (streaked tuftedcheek), a bird circumscribed by Frédéric de Lafresnaye in 1840. Ornithological taxa described by Boissonneau * Black-chested mountain tanager - ''Cnemathraupis eximia''. * Blue-and-black tanager - ''Tangara vassorii''. * Blue cotinga - ''Cotinga nattererii''. * Bronze-tailed thornbill - ''Chalcostigma heteropogon''. * Buff-breasted mountain tanager - ''Dubusia taeniata''. * Collared inca - ''Coeligena torquata''. * Colombian mountain grackle - ''Macroagelaius subalaris''. * Crimson-mantled woodpecker - ''Piculus rivolii''. * Glossy f ...

Bird
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 swimm ...

Colombia
Colombia (, ; ), officially the Republic of Colombia, is a country in South America with insular regions in North America—near Nicaragua's Caribbean coast—as well as in the Pacific Ocean. The Colombian mainland is bordered by the Caribbean Sea to the north, Venezuela to the east and northeast, Brazil to the southeast, Ecuador and Peru to the south and southwest, the Pacific Ocean to the west, and Panama to the northwest. Colombia is divided into 32 departments and the Capital District of Bogotá, the country's largest city. It covers an area of 1,141,748 square kilometers (440,831 sq mi), and has a population of 52 million. Colombia's cultural heritage—including language, religion, cuisine, and art—reflects its history as a Spanish colony, fusing cultural elements brought by immigration from Europe and the Middle East, with those brought by enslaved Africans, as well as with those of the various Amerindian civilizations that predate colonization. Spanis ...

Ecuador
Ecuador ( ; ; Quechuan languages, Quechua: ''Ikwayur''; Shuar language, Shuar: ''Ecuador'' or ''Ekuatur''), officially the Republic of Ecuador ( es, República del Ecuador, which literally translates as "Republic of the Equator"; Quechuan languages, Quechua: ''Ikwadur Ripuwlika''; Shuar language, Shuar: ''Ekuatur Nunka''), is a country in northwestern South America, bordered by Colombia on the north, Peru on the east and south, and the Pacific Ocean on the west. Ecuador also includes the Galápagos Islands in the Pacific, about west of the mainland. The country's Capital city, capital and largest city is Quito. The territories of modern-day Ecuador were once home to a variety of Indigenous peoples in Ecuador, Indigenous groups that were gradually incorporated into the Inca Empire during the 15th century. The territory was Spanish colonization of the Americas, colonized by Spain during the 16th century, achieving independence in 1820 as part of Gran Colombia, from which it ...

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 ...

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 ...

Range (biology)
Species distribution —or species dispersion — is the manner in which a biological taxon is spatially arranged. The geographic limits of a particular taxon's distribution is its range, often represented as shaded areas on a map. Patterns of distribution change depending on the scale at which they are viewed, from the arrangement of individuals within a small family unit, to patterns within a population, or the distribution of the entire species as a whole (range). Species distribution is not to be confused with dispersal, which is the movement of individuals away from their region of origin or from a population center of high density. Range In biology, the range of a species is the geographical area within which that species can be found. Within that range, distribution is the general structure of the species population, while dispersion is the variation in its population density. Range is often described with the following qualities: * Sometimes a distinction is made betw ...

Tertial
In music theory, ''tertian'' ( la, tertianus, "of or concerning thirds") describes any piece, chord, counterpoint etc. constructed from the intervals of (major and minor) thirds. An interval such as that between the notes A and C encompasses 3 semitone intervals (A-B-B-C) and is termed a minor third while one such as that between C and E encompasses 4 semitones (C-D-D-E-E) and is called a major third. Tertian harmony (also called tertiary harmony ) principally uses chords based on thirds; the term is typically used to contrast with quartal and quintal harmony which uses chords based on fourths or fifths. A common triad chord can be regarded as consisting of a "stack" of two consecutive thirds. This allows for four permutations, each producing a chord with distinct quality: A musical scale may also be analyzed as a succession of thirds. The meantone temperament, a system of tuning that emphasizes pure thirds, may be called "tertian". Chords built from sixths may also b ...

International Union For Conservation Of Nature
The International Union for Conservation of Nature (IUCN; officially International Union for Conservation of Nature and Natural Resources) is an international organization working in the field of nature conservation and sustainable use of natural resources. It is involved in data gathering and analysis, research, field projects, advocacy, and education. IUCN's mission is to "influence, encourage and assist societies throughout the world to conserve nature and to ensure that any use of natural resources is equitable and ecologically sustainable". Over the past decades, IUCN has widened its focus beyond conservation ecology and now incorporates issues related to sustainable development in its projects. IUCN does not itself aim to mobilize the public in support of nature conservation. It tries to influence the actions of governments, business and other stakeholders by providing information and advice and through building partnerships. The organization is best known to the wider p ...
