Black-backed Tanager
The black-backed tanager (''Stilpnia peruviana'') is a bird species in the Thraupidae family. It is endemic to the forests and shrubs of south-eastern Brazil. When first described, it was mistakenly believed that it originates from Peru, leading to the misleading scientific name ''peruviana''. It is closely related to the chestnut-backed tanager, and the two have sometimes been considered conspecific. It is threatened by habitat loss Habitat destruction (also termed habitat loss and habitat reduction) is the process by which a natural habitat becomes incapable of supporting its native species. The organisms that previously inhabited the site are displaced or dead, thereby ....

Anselme Gaëtan Desmarest
Anselme Gaëtan Desmarest (6 March 1784 – 4 June 1838) was a French Zoology, zoologist and author. He was the son of Nicolas Desmarest and father of Eugène Anselme Sébastien Léon Desmarest. Desmarest was a disciple of Georges Cuvier and Alexandre Brongniart, and in 1815, he succeeded Pierre André Latreille to the professorship of zoology at the '. He was elected to the American Philosophical Society in 1819 and to the Académie Nationale de Médecine in 1820. Desmarest published ' (1805), ' (1825), ' (1820) and ' (1816–30, with André Marie Constant Duméril). The brown algae ''Desmarestia'' is named in honour of Desmarest, as well as the family (Desmarestiaceae) — and in turn, the order (Desmarestiales) — of which the genus is the type species#In botany, type species.

Bird
Birds are a group of warm-blooded vertebrates constituting the class Aves (), characterised by feathers, toothless beaked jaws, the laying of hard-shelled eggs, a high metabolic rate, a four-chambered heart, and a strong yet lightweight skeleton. Birds live worldwide and range in size from the bee hummingbird to the ostrich. There are about ten thousand living species, more than half of which are passerine, or "perching" birds. Birds have 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 loss of flight in some birds, including ratites, penguins, and diverse endemic island species. The digestive and respiratory systems of birds are also uniquely adapted for flight. Some bird species of aquatic environments, particularly seabirds and some waterbirds, have further evolved for swimming. B ...

Thraupidae
The tanagers (singular ) comprise the bird family Thraupidae, in the order Passeriformes. The family has a Neotropical distribution and is the second-largest family of birds. It represents about 4% of all avian species and 12% of the Neotropical birds. Traditionally, the family contained around 240 species of mostly brightly colored fruit-eating birds. As more of these birds were studied using modern molecular techniques, it became apparent that the traditional families were not monophyletic. ''Euphonia'' and ''Chlorophonia'', which were once considered part of the tanager family, are now treated as members of the Fringillidae, in their own subfamily (Euphoniinae). Likewise, the genera ''Piranga'' (which includes the scarlet tanager, summer tanager, and western tanager), '' Chlorothraupis'', and '' Habia'' appear to be members of the cardinal family, and have been reassigned to that family by the American Ornithological Society. Description Tanagers are small to medium-sized b ...

Endemic
Endemism is the state of a species being found 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 be also be referred to as an ''endemism'' or in scientific literature as an ''endemite''. For example '' Cytisus aeolicus'' is an endemite of the Italian flora. '' Adzharia renschi'' was once believed to be an endemite of the Caucasus, but it was later discovered to be a non-indigenous species from South America belonging to a different genus. The extreme opposite of an endemic species is one with a cosmopolitan distribution, having a global or widespread range. A rare alternative term for a species that is endemic is "precinctive", which applies to ...

Chestnut-backed Tanager
The chestnut-backed tanager (''Stilpnia preciosa'') is a species of bird in the family Thraupidae. It is found in southern Brazil, north-eastern Argentina, eastern Paraguay, and Uruguay Uruguay (; ), officially the Oriental Republic of Uruguay ( es, República Oriental del Uruguay), is a country in South America. It shares borders with Argentina to its west and southwest and Brazil to its north and northeast; while bordering .... It is closely related to the rarer black-backed tanager, and females of the two species are indistinguishable. This bird is characterized by its green breast, and chestnut colored back. Before research was completed, this animal was often mistaken for a result of a mutated black-backed tanager (''Stilpnia peruviana''). It is now known that this is not the case, and though the two species are related, they are not in fact the same species. The tanager is not in any danger, and is plentiful in the areas that it resides in. Further studies show that t ...

Conspecific
Biological specificity is the tendency of a characteristic such as a behavior or a biochemical variation to occur in a particular species. Biochemist Linus Pauling stated that "Biological specificity is the set of characteristics of living organisms or constituents of living organisms of being special or doing something special. Each animal or plant species is special. It differs in some way from all other species...biological specificity is the major problem about understanding life." Biological specificity within ''Homo sapiens'' ''Homo sapiens'' has many characteristics that show the biological specificity in the form of behavior and morphological traits. Morphologically, humans have an enlarged cranial capacity and more gracile features in comparison to other hominins. The reduction of dentition is a feature that allows for the advantage of adaptability in diet and survival. As a species, humans are culture dependent and much of human survival relies on the culture and so ...

Habitat Loss
Habitat destruction (also termed habitat loss and habitat reduction) is the process by which a natural habitat becomes incapable of supporting its native species. The organisms that previously inhabited the site are displaced or dead, thereby reducing biodiversity and species abundance. Habitat destruction is the leading cause of biodiversity loss. Fragmentation and loss of habitat have become one of the most important topics of research in ecology as they are major threats to the survival of endangered species. Activities such as harvesting natural resources, industrial production and urbanization are human contributions to habitat destruction. Pressure from agriculture is the principal human cause. Some others include mining, logging, trawling, and urban sprawl. Habitat destruction is currently considered the primary cause of species extinction worldwide. Environmental factors can contribute to habitat destruction more indirectly. Geological processes, climate change, introdu ...

Stilpnia
''Stilpnia'' is a genus of Neotropical birds in the tanager family Thraupidae. Many of these tanagers have a contrasting cap or hood and most have green or gold and throats. Taxonomy and species list These species were formerly placed in the genus '' Tangara''. A molecular phylogenetic study published in 2014 found that ''Tangara'' was polyphyletic. In the rearrangement to create monophyletic genera, the genus, ''Stilpnia'', was erected with the black-headed tanager as the type species. The genus name is from the Ancient Greek στιλπνή/''stilpni'' meaning "glittering" or "glistening". The genus contains 14 species: * Black-headed tanager, ''Stilpnia cyanoptera'' * Silver-backed tanager, ''Stilpnia viridicollis'' * Sira tanager, ''Stilpnia phillipsi'' * Straw-backed tanager, ''Stilpnia argyrofenges'' * Black-capped tanager, ''Stilpnia heinei'' * Golden-hooded tanager, ''Stilpnia larvata'' * Blue-necked tanager, ''Stilpnia cyanicollis'' * Masked tanager, ''Stilpnia ni ...
