Thryorchilus
The timberline wren (''Thryorchilus browni'') is a species of bird in the family Troglodytidae. It is found in Costa Rica and western Panama. Taxonomy and systematics The timberline wren is the only member of genus ''Thryorchilus'', but its taxonomy at the subspecies level is unsettled. The International Ornithological Committee (IOC) considers it to be monotypic. The Cornell Lab of Ornithology's ''Birds of the World'' lists three subspecies, but notes that this treatment is disputed and that timberline wren should be "perhaps better considered monotypic."Kroodsma, D.

Harry Church Oberholser
Harry Church Oberholser (June 25, 1870 – December 25, 1963) was an American ornithologist. Biography Harry Oberholser was born to Jacob and Lavera S. Oberholser on June 25, 1870, in Brooklyn, New York. He attended Columbia University, but did not graduate. Later, Oberholser was awarded degrees ( B.A., M.S., and PhD.) from the George Washington University. He married Mary Forrest Smith on June 30, 1914. From 1895 to 1941, he was employed by the United States Bureau of Biological Survey (later the United States Fish and Wildlife Service) as an ornithologist, biologist, and editor. During his career, he collected bird specimens while on trips with Vernon Bailey and Louis Agassiz Fuertes. In 1928, Oberholser helped organize thWinter Waterfowl Survey which continues to this day. In 1941, at the age of 70, he became curator of ornithology Ornithology, from Ancient Greek ὄρνις (''órnis''), meaning "bird", and -logy from λόγος (''lógos''), meaning "study" ...

Supercilium
The supercilium is a plumage feature found on the heads of some bird species. It is a stripe which runs from the base of the bird's beak above its eye, finishing somewhere towards the rear of the bird's head.Dunn and Alderfer (2006), p. 10 Also known as an "eyebrow", it is distinct from the eyestripe, which is a line that runs across the lores, and continues behind the eye. Where a stripe is present only above the lores, and does not continue behind the eye, it is called a supraloral stripe or simply supraloral. On most species which display a supercilium, it is paler than the adjacent feather tracts. The colour, shape or other features of the supercilium can be useful in bird identification. For example, the supercilium of the dusky warbler, an Old World warbler The Old World warblers are a large group of birds formerly grouped together in the bird family Sylviidae. They are not closely related to the New World warblers. The family held over 400 species in over 70 genera, ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Endemic Birds Of The Talamancan Montane Forests
Endemism is the state of a species being found only in a single defined geographic location, such as an island, state, nation, country or other defined zone; organisms that are indigenous to a place are not endemic to it if they are also found elsewhere. For example, the Cape sugarbird is found exclusively in southwestern South Africa and is therefore said to be ''endemic'' to that particular part of the world. An endemic species can also be referred to as an ''endemism'' or, in scientific literature, as an ''endemite''. Similarly, many species found in the Western ghats of India are examples of endemism. Endemism is an important concept in conservation biology for measuring biodiversity in a particular place and evaluating the risk of extinction for species. Endemism is also of interest in evolutionary biology, because it provides clues about how changes in the environment cause species to undergo range shifts (potentially expanding their range into a larger area or becomi ...

IUCN
The International Union for Conservation of Nature (IUCN) is an international organization working in the field of nature conservation and sustainable use of natural resources. Founded in 1948, IUCN has become the global authority on the status of the natural world and the measures needed to safeguard it. It is involved in data gathering and Data analysis, 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 buildin ...

Páramo
Páramo () may refer to a variety of alpine tundra ecosystems located in the Andes Mountain Range, South America. Some ecologists describe the páramo broadly as "all high, tropical, montane vegetation above the continuous timberline". A narrower term classifies the páramo according to its regional placement in the northern Andes of South America and adjacent southern Central America. The páramo is the ecosystem of the regions above the continuous forest line, yet below the permanent snowline. It is a "Neotropical high mountain biome with a vegetation composed mainly of giant rosette plants, shrubs and grasses". According to scientists, páramos may be "evolution, evolutionary hot spots", meaning that they are among the fastest evolving regions on Earth. Location The Northern Andean Páramo global ecoregion includes the Cordillera Central páramo (Ecuador, Peru), Santa Marta páramo (Colombia), Cordillera de Merida páramo (Venezuela) and Northern Andean páramo (Colombia, Ec ...

Volcán Barú
The Volcán Barú (also Volcán de Chiriquí) is an active stratovolcano and the tallest mountain in Panama, at high. It lies about off the border of Costa Rica. It is also the twelfth highest peak in Central America. Due to its height and the narrowness of the isthmus of Panama, it is possible (though relatively rare) to see both the Pacific Ocean and Caribbean Sea from Volcán Barú's peak on a clear day. Geography The small town of Volcán at the base of Volcán Barú sits on the remnants of a huge lahar that appears to have breached the caldera. A small river has eroded the lahar exposing an ancient forest below dated to about 1000 years old. Volcán Barú is surrounded by a fertile area of cool highlands drained by the Chiriquí Viejo and Caldera Rivers. The towns of Volcán and Cerro Punta can be found on its western side, while Boquete is on the eastern flank. The occasional fall of hail or ice pellets has been reported on the summit, where the minimum temperature ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Turrialba Volcano
Turrialba Volcano is an active volcano in central Costa Rica that has been explosively eruptive in recent years including 2016 and in January, March and April 2017. Visitors used to be able to hike down into the main crater, but increased volcanic activity in 2014–17, resulting in large clouds of volcanic ash, led to the closure of the surrounding Turrialba Volcano National Park. However, with the eruptions subsiding, the park and access to the volcano reopened on December 4, 2020. The stratovolcano is high and is about 45 minutes from the Atlantic slope town of Turrialba (district), Turrialba. The summit has three craters, the largest of which has a diameter of . Turrialba is adjacent to Irazú Volcano, Irazú and both are among Costa Rica's largest volcanoes. Turrialba has had at least five large explosive eruptions in last 3500 years. The volcano is monitored by the Deep Earth Carbon Degassing Project. On clear days both the Pacific Ocean and Caribbean Sea can b ...

Handbook Of Birds Of The World
The ''Handbook of the Birds of the World'' (HBW) is a multi-volume series produced by the Spanish publishing house Lynx Edicions in partnership with BirdLife International. It is the first handbook to cover every known living species of bird. The series was edited by Josep del Hoyo, Andrew Elliott, Jordi Sargatal and David A. Christie. All 16 volumes have been published. For the first time an animal class will have all the species illustrated and treated in detail in a single work. This has not been done before for any other group in the animal kingdom. Material in each volume is grouped first by family, with an introductory article on each family; this is followed by individual species accounts (taxonomy, subspecies and distribution, descriptive notes, habitat, food and feeding, breeding, movements, status and conservation, bibliography). In addition, all volumes except the first and second contain an essay on a particular ornithological theme. More than 200 renowned spec ...
