Idiopsar Bracyurus
''Idiopsar'' is a genus of Neotropical seed-eating birds in the tanager family Thraupidae. Taxonomy and species list The genus ''Idiopsar'' was introduced in 1867 by the American ornithologist John Cassin to accommodate the newly described boulder finch. The name combines the Ancient Greek ''idios'' meaning "distinct" or "peculiar" with ''psar'' meaning "starling". This genus formerly contained a single species, the boulder finch. A molecular phylogenetic study of the tanager family (Thraupidae) published in 2014 found that the boulder finch was a member of a clade that contained three species assigned to other genera. In the ensuing reorganization of generic boundaries, these three species were assigned to ''Idiopsar''. The same genetic study found that ''Idiopsar'' is sister to the tit-like dacnis in the monospecific genus ''Xenodacnis''. The genus contains four species. * Red-backed sierra finch, ''Idiopsar dorsalis'' (formerly assigned to ''Phrygilus''; alternatively p ...

Red-backed Sierra Finch
The red-backed sierra finch (''Idiopsar dorsalis'') is a species of bird in the family Thraupidae. It is found in the Southern Andean Yungas of Bolivia and northern Chile and Argentina, where its natural habitat is subtropical or tropical high-altitude grassland A grassland is an area where the vegetation is dominated by grasses (Poaceae). However, sedge (Cyperaceae) and rush (Juncaceae) can also be found along with variable proportions of legumes, like clover, and other herbs. Grasslands occur natur ....

Sister Taxon
In phylogenetics, a sister group or sister taxon, also called an adelphotaxon, comprises the closest relative(s) of another given unit in an evolutionary tree. Definition The expression is most easily illustrated by a cladogram: Taxon A and taxon B are sister groups to each other. Taxa A and B, together with any other extant or extinct descendants of their most recent common ancestor (MRCA), form a monophyletic group, the clade AB. Clade AB and taxon C are also sister groups. Taxa A, B, and C, together with all other descendants of their MRCA form the clade ABC. The whole clade ABC is itself a subtree of a larger tree which offers yet more sister group relationships, both among the leaves and among larger, more deeply rooted clades. The tree structure shown connects through its root to the rest of the universal tree of life. In cladistic standards, taxa A, B, and C may represent specimens, species, genera, or any other taxonomic units. If A and B are at the same taxonomi ...

Boulder Finch
The boulder finch or short-tailed finch (''Idiopsar brachyurus'') is a species of bird previously placed in the family Emberizidae, but it appears to be related to the sierra finches ''Phrygilus'' of the tanager family Thraupidae and is now placed there. It is found in Argentina, Bolivia, and Peru. Its natural habitat is subtropical or tropical high-altitude grassland A grassland is an area where the vegetation is dominated by grasses (Poaceae). However, sedge (Cyperaceae) and rush (Juncaceae) can also be found along with variable proportions of legumes, like clover, and other herbs. Grasslands occur natur ....

Diuca
The diuca finch (''Diuca diuca'') is a species of bird in the tanager family Thraupidae. It is the only member of the genus ''Diuca''. It is found in Argentina, Bolivia, Brazil, Chile, and Uruguay. Its natural habitats are subtropical or tropical dry shrubland, subtropical or tropical high-altitude shrubland, and heavily degraded former forest. Taxonomy The diuca finch was formally described in 1782 by the Chilean naturalist Juan Ignacio Molina under the binomial name ''Fringilla diuca''. The specific epithet is from the Araucano names ''Diuca'' or ''Siuca'' for this species. With the transfer of the glacier finch (formerly white-winged diuca finch) to ''Idiopsar'' or ''Chionodacryon'', the diuca finch is now the only member of the genus ''Diuca'', which was introduced in 1850 by the German naturalist Ludwig Reichenbach.

Glacier Finch
The glacier finch (''Idiopsar speculifer''), also known as the white-winged diuca finch and glacier bird, is a species of bird in the tanager family Thraupidae. It is found in Peru, Bolivia and far northern Chile and Argentina. Its natural habitat is subtropical or tropical high-altitude grassland, where it favours wet boggy ground. It is one of the few birds that have been recorded as nesting in high altitude glaciers, hence its alternative name "the glacier bird". The nest is a bulky structure in the form of a cup, made of grass, twigs and feathers: it can weigh up to half a pound, and may be laid directly on the ice. Two eggs are laid in April or May; the young leave the nest in June or July. References External links Xeno-canto: audio recordings of the white-winged diuca finch MSN ...

Phrygilus
''Phrygilus'' is a genus of mainly Andean seed-eating tanagers commonly known as sierra finches. Phrygilos means finch in Ancient Greek. Traditionally classified in the bunting and American sparrow family Emberizidae, more recent studies have shown them to belong in the Thraupidae. Taxonomy and species list The genus ''Phrygilus'' was introduced in 1844 by the German ornithologist Jean Cabanis with the grey-hooded sierra finch as the type species. The name is from the Ancient Greek ''phrugilos'', an unidentified bird mentioned by Aristophanes. The genus formerly included additional species. A molecular phylogenetic study published in 2014 found that the genus was highly polyphyletic and in the resulting reorganization members of the genus were moved to ''Geospizopsis'', ''Rhopospina'', ''Porphyrospiza'' and ''Idiopsar''. The genus now contains four species. References Phrygilus, Bird genera {{Thraupidae-stub ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
