The tanagers 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.
The Magellanic subpolar forests are a terrestrial ecoregion of southernmost South America, covering parts of southern Chile and Argentina, and are part of the Neotropical realm. It is a temperate broadleaf and mixed forests ecoregion, and contains the world's southernmost forests.
The orange-cheeked waxbill is a common species of estrildid finch native to western and central Africa, with an estimated global extent of occurrence of 3,600,000 km2.
The tufted tit-tyrant is a species of bird in the tyrant flycatcher family Tyrannidae. This species is found in western South America; its range stretches from southern Colombia south along the Andes mountains to Tierra del Fuego. It prefers to live in upper montane forests and shrublands; however, it is a habitat generalist and can be found across a wide range of ecosystems. The tufted tit-tyrant has three subspecies, including the nominate subspecies Anairetes parulus parulus, A. p. aequatorialis, and A. p. patagonicus, and is very closely related to the Juan Fernández tit-tyrant. It is very small with a distinctive and conspicuous crest. The bird's head is black overall with white supraloral and postocular stripes. Its dull grayish-brown back contrasts with its white throat and breast that are covered with black streaks and pale, unmarked yellow underbelly. There are few noticeable differences in plumage between the subspecies. It is a vocal flycatcher with a broad repertoire of songs.
The Pampa finch, also known as the great Pampa-finch, is a species of bird. It was traditionally placed in the family Emberizidae but molecular phylogenetic studies have shown that it is a member of the tanager family Thraupidae.
The grey-crested finch is a species of bird in the tanager family Thraupidae. It is found in Bolivia and northwestern Argentina where its natural habitats are subtropical or tropical high-altitude shrubland and heavily degraded former forest. The bird was first described in 1837 by the French ornithologist Frédéric de Lafresnaye and the French zoologist Alcide d'Orbigny after the latter had collected it on an expedition he undertook for the Paris Museum to South America between 1826 and 1833.
The black-crested finch is a species of bird in the tanager family Thraupidae. It is found in Bolivia, Paraguay and northern Argentina. Its natural habitats are subtropical or tropical dry shrubland and subtropical or tropical high-altitude shrubland. It is a fairly common bird with a very wide range, and the International Union for Conservation of Nature has rated it to be a "least-concern species".
The Patagonian mockingbird is a species of bird in the family Mimidae. It is found in much of Argentina and locally in Chile.
The Inaccessible Island finch, also known as the Inaccessible bunting, is a species of bird in the family Thraupidae.
The band-tailed sierra finch is a species of bird in the family Thraupidae and is found in Argentina, Bolivia, Chile, Ecuador, and Peru. Its natural habitats are subtropical or tropical dry shrubland and subtropical or tropical high-altitude shrubland.
The black-hooded sierra finch is a species of bird in the family Thraupidae.
The carbonated sierra finch, also known as the carbon sierra finch, is a species of bird in the family Thraupidae.
The mourning sierra finch is a species of South American bird in the tanager family Thraupidae. It is the only member of the genus Rhopospina.
The grey-hooded sierra finch is a species of bird in the family Thraupidae.
The ash-breasted sierra finch is a species of bird in the family Thraupidae.
The cinnamon warbling finch is a species of bird in the family Thraupidae. It is endemic to Argentina.
The greater yellow finch is a species of bird in the family Thraupidae. It is found in Argentina and Chile. Its natural habitats are subtropical or tropical high-altitude shrubland, temperate grassland, and heavily degraded former forest.
The Patagonian yellow finch is a species of bird in the family Thraupidae. It is found in Argentina and Tierra del Fuego; also Chile. Its natural habitats are subtropical or tropical dry shrubland and temperate grassland.
The Argentine Monte (NT0802), or Low Monte, is an ecoregion of dry thorn scrub and grasslands in Argentina. It is one of the driest regions in the country. Human settlements are mainly near water supplies such as rivers or oases. Deforestation and over-grazing around these settlements have caused desertification.
The Patagonian grasslands (NT0804) is an ecoregion in the south of Argentina. The grasslands are home to diverse fauna, including several rare or endemic species of birds. There are few protected areas. The grasslands are threatened by overgrazing by sheep, which supply high-quality merino wool. Efforts are being made to develop sustainable grazing practices to avoid desertification.
