Taoniscus
The dwarf tinamou (''Taoniscus nanus'') also known as the least tinamou, is a small, superficially partridge-like bird with short tail and wings. Taxonomy and systematics All tinamou are from the family Tinamidae, and in the larger scheme are also ratites. Unlike other ratites, tinamous can fly, although in general, they are not strong fliers. All ratites evolved from prehistoric flying birds, and tinamous are the closest living relative of these birds.Davies, S. J. J. F. (2003) The dwarf tinamou is the only member of the genus ''Taoniscus'' and is a monotypic species. A phylogenetic study published in 2022 found that the dwarf tinamou was embedded within the genus ''Nothura''. Description It is approximately long. It is greyish-brown with a pale throat, boldly patterned neck and upper parts, and it has brown-barred buff underparts and a blackish crown. Some individuals are significantly darker and greyer than others, but it remains unclear if these plumage variations are ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Constantin Wilhelm Lambert Gloger
Constantin Wilhelm Lambert Gloger (17 September 1803 near Grottkau, Silesia, Kingdom of Prussia – 30 December 1863 in Berlin) was a German zoologist and ornithologist. Gloger was the first person to recognise the structural differences between swallows and swifts, and also the first to put up artificial bat boxes. He was the originator of what is now known as Gloger's rule Gloger's rule is an ecogeographical rule which states that within a species of endotherms, more heavily pigmented forms tend to be found in more humid environments, e.g. near the equator. It was named after the zoologist Constantin Wilhelm Lambert ..., which states that dark pigments increase in races of animals (birds were the examples in which he originally noticed the pattern) living in warm and humid habitats. He put forward this theory in his ''Das Abändern der Vögel durch Einfluss des Klimas'' (1833). The exact way this pattern is actually caused is still unclear, but in birds it has been suggeste ...

Cerrado
The ''Cerrado'' (, ) is a vast ecoregion of tropical savanna in eastern Brazil, particularly in the states of Goiás, Mato Grosso do Sul, Mato Grosso, Tocantins, Minas Gerais, and the Federal District. The core areas of the Cerrado biome are the Brazilian highlands – the ''Planalto''. The main habitat types of the Cerrado consist of forest savanna, wooded savanna, park savanna and gramineous-woody savanna. The ''Cerrado'' also includes savanna wetlands and gallery forests. The second largest of Brazil's major habitat types, after the Amazonian rainforest, the Cerrado accounts for a full 21 percent of the country's land area (extending marginally into Paraguay and Bolivia). The first detailed European account of the Brazilian cerrados was provided by Danish botanist Eugenius Warming (1892) in the book ''Lagoa Santa'', : The above is the original. There are other, later French and Portuguese translations not listed here. in which he describes the main features of the c ...

Formosa's northeast end touches Asunción, Paraguay, and the province borders the provinces of Chaco Province, Chaco and Salta Province, Salta to its south and west, respectively.

These sailors were searching for the legendary Sierra del Plata. History Native inhabitants of these lands include the Pilagás, Wichis and Toba people, Tobas, whose languages are still spoken in the province.

Río Bermejo
The Bermejo River ( Spanish, Río Bermejo) is a river in South America that flows from Bolivia to the Paraguay River in Argentina. The river is generally called Bermejo in spite of its different names along its way, but it also has its own Native American names; in Wichí it is called Teuco, and in Guaraní it is called Ypitá. In the plains of Argentina's Gran Chaco the Bermejo forms wetlands and splits into two branches. The southern branch is the bed of the old Bermejo River, now an intermittent stream called Río Bermejito. The northern branch is now the main stem of the Bermejo and is called the Teuco River (''Río Teuco''), Bermejo Nuevo, or simply the Bermejo River. The two branches rejoin at , near Villa Río Bermejito, forming the Lower Bermejo River. The Bermejo River is long and has a drainage basin of in area. Its mean annual discharge is irregular and varies between and . The river is born in a mountain range known as Sierra de Santa Victoria around coordinate ...
