Cerrado in the context of "Piauí"

Brazil, officially the Federative Republic of Brazil, is the largest country in South America. It is also the world's fifth-largest country by area and the seventh-largest by population, with over 213 million people. The country is a federation composed of 26 states and a Federal District, which hosts the capital, Brasília. Its most populous city is São Paulo, followed by Rio de Janeiro. Brazil has the most Portuguese speakers in the world and is the only country in the Americas where Portuguese is an official language.

Bounded by the Atlantic Ocean on the east, Brazil has a coastline of 7,491 kilometers (4,655 mi). Covering roughly half of South America's land area, it borders all other countries and territories on the continent except Ecuador and Chile. Brazil encompasses a wide range of tropical and subtropical landscapes, as well as wetlands, savannas, plateaus, and low mountains. It contains most of the Amazon basin, including the world's largest river system and most extensive virgin tropical forest. Brazil has diverse wildlife, a variety of ecological systems, and extensive natural resources spanning numerous protected habitats. The country ranks first among 17 megadiverse countries, with its natural heritage being the subject of significant global interest, as environmental degradation (through processes such as deforestation) directly affect global issues such as climate change and biodiversity loss.

A savanna or savannah is a mixed woodland-grassland (i.e. grassy woodland) biome and ecosystem characterised by the trees being sufficiently widely spaced so that the canopy does not close. The open canopy allows sufficient light to reach the ground to support an unbroken herbaceous layer consisting primarily of grasses. Four savanna forms exist; savanna woodland, where trees and shrubs form a light canopy; tree savanna, with scattered trees and shrubs; shrub savanna, with distributed shrubs; and grass savanna, where trees and shrubs are mostly nonexistent.

Savannas maintain an open canopy despite a high tree density. It is often believed that savannas feature widely spaced, scattered trees. However, in many savannas, tree densities are higher and trees are more regularly spaced than in forests. The South American savanna types cerrado sensu stricto and cerrado dense typically have densities of trees similar to or higher than that found in South American tropical forests, with savanna ranging from 800 to 3300 trees per hectare (trees/ha) and adjacent forests with 800–2000 trees/ha. Similarly Guinean savanna has 129 trees/ha, compared to 103 for riparian forest, while Eastern Australian sclerophyll forests have average tree densities of approximately 100 per hectare, comparable to savannas in the same region.

Minas Gerais (Brazilian Portuguese: [ˈminɐz ʒeˈɾajs] ; English: /ˈmɪnəs dʒəˈraɪs/ MIN-əs jə-RYS lit. 'General Mines') is one of the 27 federative units of Brazil, being the fourth largest state by area and the second largest in number of inhabitants with a population of 20,539,989 according to the 2022 census. Located in the Southeast Region of the country, it is bordered to south and southwest by São Paulo; Mato Grosso do Sul to the west; Goiás and the Federal District to the northwest; Bahia to the north and northeast; Espírito Santo to the east; and Rio de Janeiro to the southeast. The state's capital and largest city, Belo Horizonte, is a major urban and finance center in Brazil, being the sixth most populous municipality in the country while its metropolitan area ranks as the third largest in Brazil with just over 5.8 million inhabitants, after those of São Paulo and Rio de Janeiro. Minas Gerais' territory is subdivided into 853 municipalities, the largest number among Brazilian states.

The state's terrain is quite rugged and some of Brazil's highest peaks are located in its territory. It is also home to the source of some of Brazil's main rivers, such as the São Francisco, Grande, Paranaíba, Doce and Jequitinhonha rivers, which places it in a strategic position with regard to the country's water resources. It has a tropical climate, which varies from colder and humid in the south to semi-arid in its northern portion. All of these combined factors provide it with a rich fauna and flora distributed in the biomes that cover the state, especially the Cerrado and the threatened Atlantic Forest.

Mato Grosso (Portuguese pronunciation: [ˈmatu ˈɡɾosu] – 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. It is divided into 142 municipalities and covers an area of 903,357 square kilometers, consequently 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 its 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 thousand species of animals and many aquatic birds.

Tocantins (Brazilian Portuguese: [tokɐ̃ˈtʃĩs] ) is one of the 26 states of Brazil. It is the newest state, formed in 1988 and encompassing what had formerly been the northern two-fifths of the state of Goiás. Tocantins covers 277,620.91 square kilometres (107,190.03 sq mi) and had an estimated population of 1,496,880 in 2014. Construction of its capital, Palmas, began in 1989; most of the other cities in the state date to the Portuguese colonial period. With the exception of Araguaína, there are few other cities with a significant population in the state. The government has invested in a new capital, a major hydropower dam, railroads and related infrastructure to develop this primarily agricultural area. The state has 0.75% of the Brazilian population and is responsible for 0.5% of the Brazilian GDP.

Tocantins has attracted hundreds of thousands of new residents, primarily to Palmas. It is building on its hydropower resources. The Araguaia and Tocantins rivers drain the largest watershed that lies entirely inside Brazilian territory. The Rio Tocantins has been dammed for hydropower, creating a large reservoir that has become a center of recreation. Because it is in the central zone of the country, Tocantins has characteristics of the Amazon Basin, and also semi-open pastures, known as cerrado. The Bananal Island (Ilha do Bananal), in the southwest of the State, is the second largest fluvial island in the world. Tocantins is also home to the Araguaia National Park, the Carajás Indian reservations, and Jalapão State Park, which is about 250 kilometres (160 mi) from Palmas. There, the rivers create oases in the dry landscape, attracting many ecotourists to the region.

According to IBGE (2004), Brazil has its territory occupied by six terrestrial biomes and one marine biome.

The toco toucan (Ramphastos toco) is a species of bird in the toucan family Ramphastidae. It is the largest species of toucan and has a distinctive appearance, with a black body, a white throat, chest and uppertail-coverts, and red undertail-coverts. Its most conspicuous feature is its huge beak, which is yellow-orange with a black base and large spot on the tip. It is endemic to South America, where it has a wide distribution from the Guianas south to northern Argentina and Uruguay, and its range has recently been expanding southwards. Unlike other toucans, which inhabit continuous forests, toco toucans inhabit a variety of semi-open habitats at altitudes of up to 1,750 m (5,740 ft). They are especially common in the Brazilian cerrado, gallery forests, and the wetlands of the Pantanal.

Toco toucans mainly feed on fleshy fruits, but also supplement their diets with insects, eggs, and the nestlings of other birds. They will eat any available sugar-rich fruits, and show a high level of variation in their diet depending on the surrounding habitat. Breeding is seasonal, with the timing of the breeding season differing between regions. Nests are usually made in hollows in trees and contain two to four eggs; both parents incubate the eggs for 17–18 days before hatching. It is considered to be of Least Concern by BirdLife International.
