Cercibis
The sharp-tailed ibis (''Cercibis oxycerca'') is a species of ibis native to open wet savannas in parts of northern South America. Taxonomy and systematics The sharp-tailed ibis is monotypic, being the only representative of the genus ''Cercibis''.Blake ER. 1977. ''Manual of Neotropical Birds'', vol I. University of Chicago Press, Chicago. Much remains unknown about this ibis's evolutionary history;Hancock JA, Kushlan JA, Kahl MP. 1992. ''Storks, Ibises and Spoonbills of the World''. Academic Press. however, phylogenetics, phylogenetic analyses based on skull morphology and function suggest that it is closely related to the spoonbills. Description This large ibis measures 75–86 cm in length, with males being slightly larger than females. In adult males, the flat wing measures 390–415mm lengthways, and the culmen (bird), culmen measures 156–168mm from the base of the bill. In adult females, the wing is 376–413mm long and the culmen 144–197mm. The species is disting ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Ibis
The ibises () (collective plural ibis; classical plurals ibides and ibes) are a group of long-legged wading birds in the family Threskiornithidae, that inhabit wetlands, forests and plains. "Ibis" derives from the Latin and Ancient Greek word for this group of birds. It also occurs in the scientific name of the cattle egret (''Bubulcus ibis'') mistakenly identified in 1757 as being the sacred ibis. Description Ibises all have long, downcurved bills, and usually feed as a group, probing mud for food items, usually crustaceans. They are monogamous and highly territorial while nesting and feeding. Most nest in trees, often with spoonbills or herons. All extant species are capable of flight, but two extinct genera were flightless, namely the kiwi-like '' Apteribis'' in the Hawaiian Islands, and the peculiar '' Xenicibis'' in Jamaica. The word ''ibis'' comes from Latin ''ibis'' from Greek ἶβις ''ibis'' from Egyptian ''hb'', ''hīb''. Beekes, R. S. P. (2009) ''Etymologic ...

Johann Georg Wagler
Johann Georg Wagler (28 March 1800 – 23 August 1832) was a German herpetologist and ornithologist. Wagler was assistant to Johann Baptist von Spix, and gave lectures in zoology at the Ludwig Maximilian University of Munich after it was moved to Munich. He worked on the extensive collections brought back from Brazil by Spix, and published partly together with him books on reptiles from Brazil. Wagler wrote ''Monographia Psittacorum'' (1832), which included the correct naming of the blue macaws. In 1832, Wagler died of an accidental self-inflicted gunshot wound while out collecting in München-Moosach. Life Johann Georg Wagler was a German naturalist and scientist in the 19th century, whose works primarily focused on herpetology and ornithology (Beolens, Watkins & Grayson, 2011). Johan Georg Wagler was born on the 28th of March 1800, in the city of Nuremberg, where the Chancellor of the City Court was Wagler's father (Wagler, 1884). After taking up gymnastics at Nuremberg, J ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Guyana
Guyana ( or ), officially the Cooperative Republic of Guyana, is a country on the northern mainland of South America. Guyana is an indigenous word which means "Land of Many Waters". The capital city is Georgetown. Guyana is bordered by the Atlantic Ocean to the north, Brazil to the south and southwest, Venezuela to the west, and Suriname to the east. With , Guyana is the third-smallest sovereign state by area in mainland South America after Uruguay and Suriname, and is the second-least populous sovereign state in South America after Suriname; it is also one of the least densely populated countries on Earth. It has a wide variety of natural habitats and very high biodiversity. The region known as " the Guianas" consists of the large shield landmass north of the Amazon River and east of the Orinoco River known as the "land of many waters".

Gallery Forest
A gallery forest is one formed as a corridor along rivers or wetlands, projecting into landscapes that are otherwise only sparsely treed such as savannas, grasslands, or deserts. The gallery forest maintains a more temperate microclimate above the river. Defined as long and narrow forest vegetation associated with rivers, gallery forests are structurally and floristically heterogeneous. The habitats of these forests differ from the surrounding landscapes because they are, for example, more nutrient-rich or moister and/or there is less chance of fires. The forests are sometimes only a few meters wide, because they depend on the water they lie along. Ecology characteristics The riparian zones in which they grow offer greater protection from fire which would kill tree seedlings. In addition, the alluvial soils of the gallery habitat are often of higher fertility and have better drainage than the soils of the surrounding landscape with a more reliable water supply at depth.

Mato Grosso
Mato Grosso ( – lit. "Thick Bush") is one of the states of Brazil, the third largest by area, located in the Central-West region. The state has 1.66% of the Brazilian population and is responsible for 1.9% of the Brazilian GDP. Neighboring states (from west clockwise) are: Rondônia, Amazonas, Pará, Tocantins, Goiás and Mato Grosso do Sul. The state is roughly 82.2% of the size of its southwest neighbor, the nation of Bolivia. A state with a flat landscape that alternates between vast '' chapadas'' and plain areas, Mato Grosso contains three main ecosystems: the Cerrado, the Pantanal and the Amazon rainforest. The Chapada dos Guimarães National Park, with caves, grottoes, tracks, and waterfalls, is one of its tourist attractions. The extreme northwest of the state has a small part of the Amazonian forest. The Xingu Indigenous Park and the Araguaia River are in Mato Grosso. Farther south, the Pantanal, the world's largest wetland, is the habitat for nearly one tho ...

Branco River
The Branco River ( pt, Rio Branco; Engl: ''White River'') is the principal affluent of the Rio Negro from the north. Basin The river drains the Guayanan Highlands moist forests ecoregion. It is enriched by many streams from the Tepui highlands which separate Venezuela and Guyana from Brazil. Its two upper main tributaries are the Uraricoera and the Takutu. The latter almost links its sources with those of the Essequibo; during floods headwaters of the Branco and those of the Essequibo are connected, allowing a level of exchange in the aquatic fauna (such as fish) between the two systems. The Branco flows nearly south, and finds its way into the Negro through several channels and a chain of lagoons similar to those of the latter river. It is long, up to its Uraricoera confluence. It has numerous islands, and, above its mouth, it is broken by a bad series of rapids. Water chemistry As suggested by its name, the Branco (literally "white" in Portuguese) has whitish water that ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Llanos
The Llanos ( Spanish ''Los Llanos'', "The Plains"; ) is a vast tropical grassland plain situated to the east of the Andes in Colombia and Venezuela, in northwestern South America. It is an ecoregion of the tropical and subtropical grasslands, savannas, and shrublands biome. Geography The Llanos occupy a lowland that extends mostly east and west. The Llanos are bounded on the west and northwest by the Andes, and on the north by the Venezuelan Coastal Range. The Guiana Highlands are to the southeast, and the Negro-Branco moist forests are to the southwest. To the east the Orinoco wetlands and Orinoco Delta swamp forests occupy the Orinoco Delta. The Llanos' main river is the Orinoco, which runs from west to east through the ecoregion and forms part of the border between Colombia and Venezuela. The Orinoco is the major river system of Venezuela. Climate The ecoregion has a tropical savanna climate that grades into a tropical monsoon climate in the Colombian Llanos. ...
