Yellow-faced Parrot
:''The yellow-fronted parrot (Poicephalus flavifrons) from Africa is occasionally called "yellow-faced parrot".'' The yellow-faced parrot (''Alipiopsitta xanthops''), formerly also known as the yellow-faced amazon, is the only species of the genus ''Alipiopsitta''. It is a Neotropical parrot (tribe Arini), and was classified in the genus '' Amazona'' for many years. It is a predominantly green and yellow-plumaged bird with a yellow head. It is a semi-nomadic species found in the cerrado region of Brazil and adjacent Bolivia. As the yellow-faced parrot has disappeared from parts of its former range due to habitat destruction and generally occurs in low densities, it was considered vulnerable by the IUCN, but it remains locally fairly common, occurs in several protected areas and can survive in fragmented habitats, leading to its downlisting to near-threatened. Taxonomy The German naturalist Johann Baptist von Spix first described the species in 1824 as ''Psittacus xanthops' ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Yellow-fronted Parrot
The yellow-fronted parrot (''Poicephalus flavifrons'') is a parrot endemic to the Ethiopian Highlands. It is a mostly green with a yellow head. Relatively little is known about this bird. Taxonomy German naturalist Eduard Rüppell first described the yellow-fronted parrot in 1845. Its species name is derived from the Latin words ''flavus'' "yellow", and ''frons'' "forehead". It is also known as the yellow-faced parrot. Most recent authorities treat it as monotypic, but some recognized two slightly different subspecies, ''P. f. flavifrons'' and ''P. f. aurantiiceps''.Forshaw (2006). plate 67. Description The yellow-fronted parrot is about long and is mostly green with the upper parts being a darker green, the tail being olive-brown, and the legs a dark grey-brown. The face is orange-yellow. When two subspecies are recognized, the nominate is believed to have yellow to its head and face, while in ''P. f. aurantiiceps'' some of the yellow is replaced with orange. The upper b ...

Oxford University Press
Oxford University Press (OUP) is the university press of the University of Oxford. It is the largest university press in the world, and its printing history dates back to the 1480s. Having been officially granted the legal right to print books by decree in 1586, it is the second oldest university press after Cambridge University Press. It is a department of the University of Oxford and is governed by a group of 15 academics known as the Delegates of the Press, who are appointed by the vice-chancellor of the University of Oxford. The Delegates of the Press are led by the Secretary to the Delegates, who serves as OUP's chief executive and as its major representative on other university bodies. Oxford University Press has had a similar governance structure since the 17th century. The press is located on Walton Street, Oxford, opposite Somerville College, in the inner suburb of Jericho.

Paraguay
Paraguay (; ), officially the Republic of Paraguay ( es, República del Paraguay, links=no; gn, Tavakuairetã Paraguái, links=si), is a landlocked country in South America. It is bordered by Argentina to the south and southwest, Brazil to the east and northeast, and Bolivia to the northwest. It has a population of seven million, nearly three million of whom live in the capital and largest city of Asunción, and its surrounding metro. Although one of only two landlocked countries in South America (Bolivia is the other), Paraguay has ports on the Paraguay and Paraná rivers that give exit to the Atlantic Ocean, through the Paraná-Paraguay Waterway. Spanish conquistadores arrived in 1524, and in 1537, they established the city of Asunción, the first capital of the Governorate of the Río de la Plata. During the 17th century, Paraguay was the center of Jesuit missions, where the native Guaraní people were converted to Christianity and introduced to European culture. ...

Beni Department
Beni (), sometimes El Beni, is a northeastern department of Bolivia, in the lowlands region of the country. It is the second-largest department in the country (after Santa Cruz), covering 213,564 square kilometers (82,458 sq mi), and it was created by supreme decree on November 18, 1842, during the administration of General José Ballivián. Its capital is Trinidad. Population With a population of 420,000 (2006 census), Beni is the second least-populated of the nine departments of Bolivia, after Pando. Although Beni is rich in natural resources, the poverty level of its inhabitants is high, mainly as a result of centuries of exploitation of native populations by European-descended elites. The main economic activities are agriculture, timber, and cattle. In addition, an underground economy linked to illegal narcotics activities flourished in the area during the last decades of the 20th century, with many cocaine laboratories hidden behind the façade of remote cattle ranches. ...

Caatinga
Caatinga (, ) is a type of semi-arid tropical vegetation, and an ecoregion characterized by this vegetation in interior northeastern Brazil. The name "Caatinga" is a Tupi word meaning "white forest" or "white vegetation" (''caa'' = forest, vegetation, ''tinga'' = white). The Caatinga is a xeric shrubland and thorn forest, which consists primarily of small, thorny trees that shed their leaves seasonally. Cacti, thick-stemmed plants, thorny brush, and arid-adapted grasses make up the ground layer. Most vegetation experiences a brief burst of activity during the three-month long rainy season. Caatinga falls entirely within earth's tropical zone and is one of 6 major ecoregions of Brazil. It covers 850,000 km², nearly 10% of Brazil's territory. It is home to 26 million people and over 2000 species of plants, fish, reptiles, amphibians, birds, and mammals. The Caatinga is the only exclusively Brazilian biome, which means that a large part of its biological heritage cannot ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Piauí
Piaui (, ) is one of the states of Brazil, located in the country's Northeast Region. The state has 1.6% of the Brazilian population and produces 0.7% of the Brazilian GDP. Piaui has the shortest coastline of any coastal Brazilian state at 66 km (41 mi), and the capital, Teresina, is the only state capital in the northeast to be located inland. The reason for this is, unlike the rest of the area, Piaui was first colonised inland and slowly expanded towards the ocean, rather than the other way around. In the southeast of the state, the National Park of Serra da Capivara is a UNESCO World Heritage Site. The park has more than 400 archaeological sites and the largest concentration of rock paintings in the world, in a landscape dominated by canyons and caatinga.

Sexual Dimorphism
Sexual dimorphism is the condition where the sexes of the same animal and/or plant species exhibit different morphological characteristics, particularly characteristics not directly involved in reproduction. The condition occurs in most animals and some plants. Differences may include secondary sex characteristics, size, weight, colour, markings, or behavioural or cognitive traits. These differences may be subtle or exaggerated and may be subjected to sexual selection and natural selection. The opposite of dimorphism is ''monomorphism'', which is when both biological sexes are phenotypically indistinguishable from each other. Overview Ornamentation and coloration Common and easily identified types of dimorphism consist of ornamentation and coloration, though not always apparent. A difference in coloration of sexes within a given species is called sexual dichromatism, which is commonly seen in many species of birds and reptiles. Sexual selection leads to the exaggerated dim ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Covert (feather)
A covert feather or tectrix on a bird is one of a set of feathers, called coverts (or ''tectrices''), which, as the name implies, cover other feathers. The coverts help to smooth airflow over the wings and tail. Ear coverts The ear coverts are small feathers behind the bird's eye which cover the ear opening (the ear of a bird has no external features) Tail coverts The uppertail and undertail coverts cover the base of the tail feathers above and below. Sometimes these coverts are more specialised. The "tail" of a peacock is made of very elongated uppertail coverts. Wing coverts The upperwing coverts fall into two groups: those on the inner wing, which overlay the secondary flight feathers, known as the secondary coverts, and those on the outerwing, which overlay the primary flight feathers, the primary coverts. Within each group, the feathers form a number of rows. The feathers of the outermost, largest, row are termed greater (primary-/secondary-) coverts; those in the next row ...
