Acre Antshrike
The Acre antshrike (''Thamnophilus divisorius'') is a member of the antbird family (Thamnophilidae). Its closest relatives are the streak-backed antshrike and the Amazonian antshrike. It was discovered in 1996, in the Acre Arch uplands in the state of Acre in Brazil, and described as a species new to science in 2004. It is found in low-growing woodland. Its known range lies within the remote Serra do Divisor National Park in Brazil and the adjacent Sierra del Divisor National Park in Peru, but it is believed to be common there. Because of its apparently stable population, the International Union for Conservation of Nature has listed it as a species of least concern A least-concern species is a species that has been categorized by the International Union for Conservation of Nature (IUCN) as evaluated as not being a focus of species conservation because the specific species is still plentiful in the wild.

Antbird
The antbirds are a large passerine bird family, Thamnophilidae, found across subtropical and tropical Central and South America, from Mexico to Argentina. There are more than 230 species, known variously as antshrikes, antwrens, antvireos, fire-eyes, bare-eyes and bushbirds. They are related to the antthrushes and antpittas (family Formicariidae), the tapaculos, the gnateaters and the ovenbirds. Despite some species' common names, this family is not closely related to the wrens, vireos or shrikes. Antbirds are generally small birds with rounded wings and strong legs. They have mostly sombre grey, white, brown and rufous plumage, which is sexually dimorphic in pattern and colouring. Some species communicate warnings to rivals by exposing white feather patches on their backs or shoulders. Most have heavy bills, which in many species are hooked at the tip. Most species live in forests, although a few are found in other habitats. Insects and other arthropods from the most importan ...

Streak-backed Antshrike
The streak-backed antshrike (''Thamnophilus insignis'') is a species of bird in subfamily Thamnophilinae of family Thamnophilidae, the "typical antbirds". It is found in Brazil, Guyana, and Venezuela. Taxonomy and systematics The streak-backed antshrike has two subspecies, the nominate ''T. i. insignis'' ( Salvin & Godman, 1884) and ''T. i. nigrifrontalis'' ( Phelps, WH & Phelps, WH Jr, 1947). The streak-backed and the Acre antshrike (''T. divisorius'') are sister species.Brumfield, R.T. and Edwards, S.V. (2007).

Acre (state)
Acre () is a state located in the west of the North Region of Brazil and the Amazonia Legal. Located in the westernmost part of the country, at a two-hour time difference from Brasília, Acre is bordered clockwise by the Brazilian states of Amazonas and Rondônia to the north and east, the Bolivian department of Pando to the southeast, and the Peruvian regions of Madre de Dios, Ucayali and Loreto to the south and west. The state, which has 0.42% of the Brazilian population, generates 0.2% of the Brazilian GDP. Its capital and largest city is Rio Branco. Other important places include Cruzeiro do Sul, Sena Madureira, Tarauacá and Feijó. Intense extractive activity in the rubber industry, which reached its height in the early 20th century, attracted Brazilians from many regions to the state. From the mixture of sulista, southeastern Brazil, nordestino, and indigenous traditions arose a diverse cuisine. It combines sun-dried meat ( carne-de-sol) with pirarucu ...

Bird Species New To Science
This article describes bird species discovered since 1900. Before the 20th century, and into its early decades, the pace of discovery (and "discovery") of new species was fast; during this period, with numerous collecting expeditions into species-rich areas not previously visited by western ornithologists, up to several hundred new species per decade were being described. Many of these were of course not new to the local people, but since then, the pace has slowed, and new species are generally only being found in remote areas, or among cryptic or secretive groups of species. Nonetheless, several tens of species were described for the first time even during the 1990s. Considerable time can pass between discovery and publication, for a number of reasons. Individual countries particularly rich in species newly described during this period are: * Brazil * Colombia * Peru * Indonesia * Philippines A number of individuals have been particularly prolific in describing new species, suc ...

Woodland
A woodland () is, in the broad sense, land covered with trees, or in a narrow sense, synonymous with wood (or in the U.S., the '' plurale tantum'' woods), a low-density forest forming open habitats with plenty of sunlight and limited shade (see differences between British, American, and Australian English explained below). Woodlands may support an understory of shrubs and herbaceous plants including grasses. Woodland may form a transition to shrubland under drier conditions or during early stages of primary or secondary succession. Higher-density areas of trees with a largely closed canopy that provides extensive and nearly continuous shade are often referred to as forests. Extensive efforts by conservationist groups have been made to preserve woodlands from urbanization and agriculture. For example, the woodlands of Northwest Indiana have been preserved as part of the Indiana Dunes. Definitions United Kingdom ''Woodland'' is used in British woodland management t ...

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 ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

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 ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Least Concern
A least-concern species is a species that has been categorized by the International Union for Conservation of Nature (IUCN) as evaluated as not being a focus of species conservation because the specific species is still plentiful in the wild. They do not qualify as threatened, near threatened, or (before 2001) conservation dependent. Species cannot be assigned the "Least Concern" category unless they have had their population status evaluated. That is, adequate information is needed to make a direct, or indirect, assessment of its risk of extinction based on its distribution or population status. Evaluation Since 2001 the category has had the abbreviation "LC", following the IUCN 2001 Categories & Criteria (version 3.1). Before 2001 "least concern" was a subcategory of the "Lower Risk" category and assigned the code "LR/lc" or lc. Around 20% of least concern taxa (3261 of 15636) in the IUCN database still use the code "LR/lc", which indicates they have not been re-evalua ...
