Timberline Wren
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 at the Cleveland Museum of Natural History. Oberholser was the author of a number of books and articles. A complete manuscript of his work is avai ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
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 species, can be used to distinguish it from the very similar Radde's warbler. The dusky warbler's supercilium is sharply demarcated, whitish and narrow in front of the eye, becoming broader and more buffy towards the ...

Birds Of The Talamancan Montane Forests
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] |
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.

Páramo
Páramo () can 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 "evolutionary hot spots", that meaning that it's 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, Ecuador) ter ...

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 c ... [...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, caused the surrounding Turrialba Volcano National Park to close. However, with the subsiding of the eruptions, the park and volcano reopened on December 4, 2020. The stratovolcano is high and is about 45 minutes from the Atlantic slope town of Turrialba. The summit has three craters, the largest of which has a diameter of . Turrialba is adjacent to 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 be seen from the summit. Below the summit is ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
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 specia ...
