Pale Baywing
The pale baywing (''Agelaioides fringillarius''), formerly known as the pale cowbird, is a species of bird in the family Icteridae. It is currently placed in the genus ''Agelaioides'', but has traditionally been placed in the genus ''Molothrus''. It was formerly considered conspecific with the greyish baywing, with the combined species then known as bay-winged cowbird. It is endemic to northeastern Brazil, where it is primarily found in the Caatinga and the northern Cerrado The Cerrado () is a vast ecoregion of Tropics, tropical savanna in central Brazil, being present in the states of Goiás, Mato Grosso do Sul, Mato Grosso, Tocantins, Maranhão, Piauí, Bahia, Minas Gerais, São Paulo (state), São Paulo, Paraná ....

The IUCN Red List Of Threatened Species
The International Union for Conservation of Nature (IUCN) Red List of Threatened Species, also known as the IUCN Red List or Red Data Book, founded in 1964, is an inventory of the global conservation status and extinction risk of biological species. A series of Regional Red Lists, which assess the risk of extinction to species within a political management unit, are also produced by countries and organizations. The goals of the Red List are to provide scientifically based information on the status of species and subspecies at a global level, to draw attention to the magnitude and importance of threatened biodiversity, to influence national and international policy and decision-making, and to provide information to guide actions to conserve biological diversity. Major species assessors include BirdLife International, the Institute of Zoology (the research division of the Zoological Society of London), the World Conservation Monitoring Centre, and many Specialist Groups within th ...

IUCN
The International Union for Conservation of Nature (IUCN) is an international organization working in the field of nature conservation and sustainable use of natural resources. Founded in 1948, IUCN has become the global authority on the status of the natural world and the measures needed to safeguard it. It is involved in data gathering and Data analysis, 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 buildin ...

Johann Baptist Von Spix
Johann Baptist Ritter von Spix (9 February 1781 – 13 March 1826) was a German natural history, biologist. From his expedition to Brazil, he brought to Germany a large variety of specimens of plants, insects, mammals, birds, amphibians and fish. They constitute an important basis for today's National Zoological Collection in Munich. Numerous examples of his ethnographic collections, such as dance masks and the like, are now part of the collection of the Museum Five Continents, Museum of Ethnography in Munich. Biography Spix was born in Höchstadt, Germany, the seventh of eleven children. His childhood home is the site of the Spix Museum, open to the public since 2004. He studied philosophy in Bamberg and graduated with a doctoral degree. Later he studied theology in Würzburg. After attending lectures of the young professor Friedrich Wilhelm Joseph Schelling, F. W. J. Schelling, Spix became interested in nature. He quit his theology studies and began studying medic ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Bird
Birds are a group of warm-blooded vertebrates constituting the class (biology), class Aves (), characterised by feathers, toothless beaked jaws, the Oviparity, laying of Eggshell, hard-shelled eggs, a high Metabolism, metabolic rate, a four-chambered heart, and a strong yet lightweight Bird skeleton, skeleton. Birds live worldwide and range in size from the bee hummingbird to the common ostrich. There are over 11,000 living species and they are split into 44 Order (biology), orders. More than half are passerine or "perching" birds. Birds have Bird wing, wings whose development varies according to species; the only known groups without wings are the extinct moa and elephant birds. Wings, which are modified forelimbs, gave birds the ability to fly, although further evolution has led to the Flightless bird, loss of flight in some birds, including ratites, penguins, and diverse endemism, endemic island species. The digestive and respiratory systems of birds are also uniquely a ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Icteridae
Icterids () or New World blackbirds make up a family, the Icteridae (), of small to medium-sized, often colorful, New World passerine birds. The family contains 108 species and is divided into 30 genera. Most species have black as a predominant plumage color, often enlivened by yellow, orange, or red. The species in the family vary widely in size, shape, behavior, and coloration. Etymology The name, meaning "jaundiced ones" (from the prominent yellow feathers of many species) comes from the - ''íkteros'' via the . Relationship to other species This group includes the New World blackbirds, New World orioles, the bobolink, meadowlarks, Quiscalus, grackles, cowbirds, oropendolas, and cacique (bird), caciques. Despite the similar names, the first groups are only distantly related to the Old World common blackbird (a thrush (bird), thrush) or to the Old World orioles. The Icteridae are not to be confused with the Icteriidae, a family created in 2017 and consisting of one specie ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Molothrus
Cowbirds are birds belonging to the genus ''Molothrus'' in the family Icteridae. They are of New World origin, but some species not native to North America are invasive there, and are obligate brood parasites, laying their eggs in the nests of other species. The genus was introduced by English naturalist William Swainson in 1832 with the brown-headed cowbird (''Molothrus ater'') as the type species. The genus name combines the Ancient Greek , meaning "struggle" or "battle", with , meaning "to sire" or "to impregnate". The English name "cowbird", first recorded in 1839, refers to this species often being seen near cattle. Species The genus contains six species: One extinct species, '' Molothrus resinosus'', is known from fossil remains recovered from the Talara Tar Seeps of northwestern Peru, and likely went extinct during the late Quaternary. It may have been a close associate of Pleistocene megafauna communities, and may have gone extinct following their collapse ...

Greyish Baywing
The grayish baywing (''Agelaioides badius''), formerly known as the bay-winged cowbird, is a species of bird in the family Icteridae. It is currently placed in the genus ''Agelaioides'' but has traditionally been placed in the genus ''Molothrus''. It is found in the northern half of Argentina, Bolivia, Uruguay, Paraguay and southern and central Brazil, The isolated population in north-eastern Brazil is usually now considered a separate species, the pale baywing (''Agelaioides fringillarius''). The greyish baywing has been recorded as a vagrant in Chile. Description and behavior It has a total length of approximately 18 cm (7 in). It is overall ashy-brown with contrasting black lores and rufous wings. The taxon ''fringillarius'' has more black in the face and is overall more rufescent (less ashy). It is social and commonly seen in small groups. Unlike the "true" cowbirds in the genus ''Molothrus'', this species is not a brood parasite. In contrast, the screaming cowbi ...

Endemic
Endemism is the state of a species being found only in a single defined geographic location, such as an island, state, nation, country or other defined zone; organisms that are indigenous to a place are not endemic to it if they are also found elsewhere. For example, the Cape sugarbird is found exclusively in southwestern South Africa and is therefore said to be ''endemic'' to that particular part of the world. An endemic species can also be referred to as an ''endemism'' or, in scientific literature, as an ''endemite''. Similarly, many species found in the Western ghats of India are examples of endemism. Endemism is an important concept in conservation biology for measuring biodiversity in a particular place and evaluating the risk of extinction for species. Endemism is also of interest in evolutionary biology, because it provides clues about how changes in the environment cause species to undergo range shifts (potentially expanding their range into a larger area or bec ...

Caatinga
Caatinga () is a type of semi-arid tropical vegetation, and an ecoregion characterized by this vegetation in interior northeastern Brazil. The name "Caatinga" comes from the Tupi word '' ka'atinga'', meaning "white forest" or "white vegetation" ('' ka'a'' = 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 six major biomes of Brazil. It covers 912,529 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 ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Cerrado
The Cerrado () is a vast ecoregion of Tropics, tropical savanna in central Brazil, being present in the states of Goiás, Mato Grosso do Sul, Mato Grosso, Tocantins, Maranhão, Piauí, Bahia, Minas Gerais, São Paulo (state), São Paulo, Paraná (state), Paraná and the Federal District (Brazil), 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 grass, gramineous-woody savanna. The Cerrado also includes savanna wetlands and gallery forests. The second largest of Biomes in Brazil, Brazil's major habitat types, after the Amazon rainforest, Amazonian rainforest, the Cerrado accounts for a full 21 percent of the country's land area (extending marginally into Paraguay and Bolivia). About 75% of the Cerrado’s 2 million km2 is privately owned. Vast amounts of research have shown that the Cerrado is one of the richest of all tropi ...
