Antioquia Wren
The Antioquia wren (''Thryophilus sernai'') is a passerine from the wren family (Troglodytidae). It was discovered in March 2010 in the vicinity of the Cauca River in Antioquia, Colombia and described as a new species by Lara ''et al'' (2012). The epithet commemorates the late Marco Antonio Serna Díaz (1936–1991), a Colombian naturalist from San Vicente Ferrer, Antioquia. The Antioquia wren is closely related to the rufous-and-white wren and the Niceforo's wren. It occurs on both banks of the Cauca River Canyon but it is uncommon throughout its range. Its habitat is dry forests. Principal threats to the species include habitat destruction caused by the building of the Ituango Dam. References *Lara, C. E., A. M. Cuervo, S. V. Valderrama, D.

The IUCN Red List Of Threatened Species
The International Union for Conservation of Nature (IUCN) Red List of Threatened Species, also known as the IUCN Red List or Red Data Book, founded in 1964, is the world's most comprehensive inventory of the global conservation status of biological species. It uses a set of precise criteria to evaluate the extinction risk of thousands of species and subspecies. These criteria are relevant to all species and all regions of the world. With its strong scientific base, the IUCN Red List is recognized as the most authoritative guide to the status of biological diversity. A series of Regional Red Lists are produced by countries or organizations, which assess the risk of extinction to species within a political management unit. The aim of the IUCN Red List is to convey the urgency of conservation issues to the public and policy makers, as well as help the international community to reduce species extinction. According to IUCN the formally stated goals of the Red List are to provide sc ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
IUCN
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 ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Wren
Wrens are a family of brown passerine birds in the predominantly New World family Troglodytidae. The family includes 88 species divided into 19 genera. Only the Eurasian wren occurs in the Old World, where, in Anglophone regions, it is commonly known simply as the "wren", as it is the originator of the name. The name ''wren'' has been applied to other, unrelated birds, particularly the New Zealand wrens (Acanthisittidae) and the Australian wrens (Maluridae). Most wrens are visually inconspicuous though they have loud and often complex songs. Exceptions include the relatively large members of the genus ''Campylorhynchus'', which can be quite bold in their behaviour. Wrens have short wings that are barred in most species, and they often hold their tails upright. Wrens are primarily insectivorous, eating insects, spiders and other small invertebrates, but many species also eat vegetable matter and some eat small frogs and lizards.

Cauca River
The Cauca River () is a river in Colombia that lies between the Occidental and Central cordilleras. From its headwaters in southwestern Colombia near the city of Popayán, it joins the Magdalena River near Magangue in Bolivar Department, and the combined river eventually flows out into the Caribbean Sea. It has a length of to its junction with the Magdalena, for a total length of . from origin to seamouth. The river is under the supervision of the ''Cauca Regional Corporation'' and the ''Cauca Valley Regional Autonomous Corporation'', and is navigable for above its junction with the Magdalena.

Rufous-and-white Wren
The rufous-and-white wren (''Thryophilus rufalbus'') is a small songbird of the wren family. It is a resident breeding species from southwesternmost Mexico to northern Colombia and northwestern Venezuela. It was formerly placed in the genus ''Thryothorus'' (Mann et al., 2006). This large wren breeds in lowlands and foothills from sea level up to altitude in dry forests or, in wetter areas, more open scrubby woodland. In Central America, it mainly occurs on the Pacific side of the central mountain ranges Its flask-shaped nest is constructed high in a tree or shrub. The female alone incubates the three or four greenish-blue eggs for about two weeks to hatching, and the young fledge in about the same length of time again. The adult rufous-and-white wren is long and weighs . It has chestnut brown upperparts with a darker crown, strong white supercilium, brown stripe through the eye and black streaking on the cheeks. The underparts are white, with black barring on the lower belly ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Niceforo's Wren
Niceforo's wren (''Thryophilus nicefori'') is a species of bird in the family Troglodytidae. It is endemic to Colombia. Its natural habitat is subtropical or tropical high-altitude dry shrubland. It is threatened by habitat loss. In Spanish the bird is known as Cucarachero de Nicéforo or Cucarachero del Chicamocha. Taxonomy Niceforo's wren was first formally described in 1946 by the American ornithologist Rodolphe Meyer de Schauensee. The genus name derives from the Ancient Greek ''thruon'' - reed, and ''philos'' - loving. The species name commemorates Brother Nicéforo María, a Colombian missionary and herpetologist who provided Meyer de Schauensee with many specimens. The type-locality site is San Gil on the río Fonce south of Bucaramanga, in Santander, where ten specimens were collected between 1944 and 1948. Previously considered part of the genus ''Thryothorus'' and frequently treated as a subspecies of Rufous-and-white wren (''Thryophilus rufalbus''), Niceforo's w ...

Habitat Destruction
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 ...

Ituango Dam
The Ituango Dam, also referred to as the Pescadero-Ituango Dam or Hidroituango, is an embankment dam currently under construction on the Cauca River near Ituango in Antioquia Department, Colombia. The primary purpose of the project is hydroelectric power generation and its power plant will have an installed capacity of if completed. Preliminary construction on the dam began in September 2011 and the power plant was expected to begin operations in late 2018, but will not after heavy rainfall and landslides in April/May 2018 blocked the river's diversion tunnel, threatening a breach of the dam. If completed, it will be the largest power station in Colombia. Background The dam's feasibility study was completed in 1983 but the project was shelved in the 1990s due to an economic crisis. The final designs for the project were finished in 2008 and on 8 July 2011, the project management contract was awarded. Preliminary construction (surveying, roads, bridges, diversion tunnels) began ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
