Striated Antbird
The striated antbird (''Drymophila devillei'') is a species of bird in subfamily Thamnophilinae of family Thamnophilidae, the "typical antbirds". It is found in Bolivia, Brazil, Colombia, Ecuador, and Peru. Taxonomy and systematics The striated antbird has two subspecies, the nominate ''D. d. devillei'' ( Ménégaux & Hellmayr, 1906) and ''D. d. subochracea'' ( Chapman, 1921). Some authors have suggested that the subspecies deserve to be treated as full species.Schulenberg, T. S. and G. M. Kirwan (2020). Striated Antbird (''Drymophila devillei''), version 1.0. In Birds of the World (T. S. Schulenberg, Editor). Cornell Lab of Ornithology, Ithaca, NY, USA. https://doi.org/10.2173/bow.strant2.01 retrieved 19 June 2024 Subspecies ''D. d. subochracea'' has sometimes been called the "Xingu antbird", which can cause it to be confused with the Xingu scale-backed antbird (''Willisornis vidua''). The striated antbird and the East Andean antbird are sister species.Remsen, J. V., Jr., ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Auguste Ménégaux
Henri Auguste Ménégaux (17 May 1857 – 15 July 1937) was a French ornithologist and malacologist born in Audincourt. He was based at the Muséum national d'histoire naturelle in Paris. From 1910, with Louis Denise (1863-1914), he was publisher of the journal, ''Revue Française d'Ornithologie Scientifique et Pratique''. In 1899 he supported his graduate thesis at the Sorbonne with a dissertation on marine bivalves titled ''Recherches sur la circulation des Lamellibranches marins''. In 1901 he replaced Eugène de Pousargues (1859-1901) as assistant to Émile Oustalet (1844-1905) at the Muséum national d'histoire naturelle (mammals and birds). Later he became deputy director of the laboratory headed by Édouard Louis Trouessart (1842-1927). His studies included birds collected by the French Antarctic Expedition commanded by Jean-Baptiste Charcot (1867-1936). In 1912 he became a founder of the ''Ligue pour la Protection des Oiseaux'' (League for the Protection of Birds). W ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Rio Madeira
The Madeira River ( pt, Rio Madeira, link=no ) is a major waterway in South America. It is estimated to be in length, while the Madeira-Mamoré is estimated near or in length depending on the measuring party and their methods. The Madeira is the biggest tributary of the Amazon, accounting for about 15% of the water in the basin. A map from Emanuel Bowen in 1747, held by the David Rumsey Map Collection, refers to the Madeira by the pre-colonial, indigenous name Cuyari. The River of Cuyari, called by the Portuguese Madeira or the Wood River, is formed by two great rivers, which join near its mouth. It was by this River, that the Nation of Topinambes passed into the River Amazon. Climate The mean inter-annual precipitations on the great basins vary from , the entire upper Madeira basin receiving . The greatest extremes of rainfall are between . Even just below the confluence that forms it, the Madeira is one of the largest rivers of the world, with a mean inter-annual discharge ...

Amazon Basin
The Amazon basin is the part of South America drained by the Amazon River and its tributaries. The Amazon drainage basin covers an area of about , or about 35.5 percent of the South American continent. It is located in the countries of Bolivia, Brazil, Colombia, Ecuador, Guyana, Peru, Suriname, and Venezuela. Most of the basin is covered by the Amazon rainforest, also known as Amazonia. With a area of dense tropical forest, this is the largest rainforest in the world. Geography The Amazon River begins in the Andes Mountains at the west of the basin with its main tributary the Marañón River and Apurimac River in Peru. The highest point in the watershed of the Amazon is the second biggest peak of Yerupajá at . With a length of about before it drains into the Atlantic Ocean, it is one of the two longest rivers in the world. A team of scientists has claimed that the Amazon is longer than the Nile, but debate about its exact length continues. The Amazon system ...

Taxonomy Articles Created By Polbot
Taxonomy is the practice and science of categorization or classification (general theory), classification. A taxonomy (or taxonomical classification) is a scheme of classification, especially a hierarchical classification, in which things are organized into groups or types. Among other things, a taxonomy can be used to organize and index knowledge (stored as documents, articles, videos, etc.), such as in the form of a library classification system, or a Taxonomy for search engines, search engine taxonomy, so that users can more easily find the information they are searching for. Many taxonomies are hierarchy, hierarchies (and thus, have an intrinsic tree structure), but not all are. Originally, taxonomy referred only to the categorisation of organisms or a particular categorisation of organisms. In a wider, more general sense, it may refer to a categorisation of things or concepts, as well as to the principles underlying such a categorisation. Taxonomy organizes taxonomic uni ...

Taxa Named By Carl Eduard Hellmayr
In biology, a taxon (back-formation from ''taxonomy''; plural taxa) is a group of one or more populations of an organism or organisms seen by taxonomists to form a unit. Although neither is required, a taxon is usually known by a particular name and given a particular ranking, especially if and when it is accepted or becomes established. It is very common, however, for taxonomists to remain at odds over what belongs to a taxon and the criteria used for inclusion. If a taxon is given a formal scientific name, its use is then governed by one of the nomenclature codes specifying which scientific name is correct for a particular grouping. Initial attempts at classifying and ordering organisms (plants and animals) were set forth in Carl Linnaeus's system in '' Systema Naturae'', 10th edition (1758), as well as an unpublished work by Bernard and Antoine Laurent de Jussieu. The idea of a unit-based system of biological classification was first made widely available in 1805 in the i ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Birds Described In 1906
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 ...

Drymophila
__NOTOC__ ''Drymophila'' is a bird genus in the antbird family (Thamnophilidae). It is a relative of the typical antwrens. The genus ''Drymophila'' was introduced by the English naturalist William Swainson in 1824. The type species is the ferruginous antbird. The name of the genus combines the Ancient Greek words for "wood" or "copse" and "fond of". Taxonomy and systematics Extant species The genus ''Drymophila'' contains the following eleven species: * Ferruginous antbird (''Drymophila ferruginea'') * Bertoni's antbird (''Drymophila rubricollis'') * Rufous-tailed antbird (''Drymophila genei'') * Ochre-rumped antbird (''Drymophila ochropyga'') * Dusky-tailed antbird (''Drymophila malura'') * Scaled antbird (''Drymophila squamata'') * Striated antbird (''Drymophila devillei'') * Santa Marta antbird (''Drymophila hellmayri'') * Klages's antbird (''Drymophila klagesi'') * East Andean antbird (''Drymophila caudata'') * Streak-headed antbird (''Drymophila striaticeps'') ...

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] |
Mixed-species Feeding Flock
A mixed-species feeding flock, also termed a mixed-species foraging flock, mixed hunting party or informally bird wave, is a flock of usually insectivorous birds of different species that join each other and move together while foraging. These are different from feeding aggregations, which are congregations of several species of bird at areas of high food availability. While it is currently unknown how mixed-species foraging flocks originate, researchers have proposed a few mechanisms for their initiation. Many believe that nuclear species play a vital role in mixed-species flock initiation. Additionally, the forest structure is hypothesized to play a vital role in these flocks' formation. In Sri Lanka, for example, vocal mimicry by the greater racket-tailed drongo might have a key role in the initiation of mixed-species foraging flocks, while in parts of the American tropics packs of foraging golden-crowned warblers might play the same role.

Guadua
''Guadua'' is a Neotropical genus of thorny, clumping bamboo in the grass family, ranging from moderate to very large species. Physically, ''Guadua angustifolia'' is noted for being the largest Neotropical bamboo. The genus is similar to ''Bambusa'' and is sometimes included in that genus. Several animals are, to a various extent, associated with stands of ''Guadua'' bamboo, for example several species of seedeaters, and the Amazon and Atlantic Bamboo Rats. Distribution and habitats The genus can be found in a wide range from northern Mexico and Trinidad to Uruguay, but most of the species are concentrated in the Amazon basin and the Orinoco basin. They usually grow at low altitudes (below 1,500 m), but has been found up to 2,500 m. Its habitats include lowland tropical and lower-montane forest, savannas, Cerrados, gallery forest, and disturbed inter-Andean valley vegetation. Human use From a utilitarian perspective, ''Guadua'' is the most important American bamboo. Due to ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
