Porphyrospiza
''Porphyrospiza'' is a genus of seed-eating South American birds in the tanager family Thraupidae. Taxonomy and species list The genus ''Porphyrospiza'' was introduced in 1873 by the English ornithologists Philip Sclater and Osbert Salvin to accommodate the blue finch. The genus name combines the Ancient Greek ''porphura'' meaning "purple" with ''spiza'' meaning "finch". The genus formerly included only a single species, the blue finch. The band-tailed sierra finch and the carbonated sierra finch were formerly placed in the genus ''Phrygilus''. They were moved to ''Porphyrospiza'' when a molecular phylogenetic study published in 2014 found that ''Phrygilus'' was polyphyletic A polyphyletic group is an assemblage of organisms or other evolving elements that is of mixed evolutionary origin. The term is often applied to groups that share similar features known as homoplasies, which are explained as a result of converg ... and that these two species were closely related to the ...

Blue Finch
The blue finch or yellow-billed blue finch (''Porphyrospiza caerulescens'') is a species of small bird. Although it was long classified in the bunting family Emberizidae, or the cardinal family Cardinalidae, more recent molecular studies have shown it fits comfortably in the Thraupini tribe within the family Thraupidae. It is found in Brazil and northeastern Bolivia, where its natural habitat is dry savanna. It is becoming rare due to habitat loss.

Band-tailed Sierra Finch (cropped)
The band-tailed sierra finch (''Porphyrospiza alaudina'') 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 Shrubland, scrubland, scrub, brush, or bush is a plant community characterized by vegetation dominated by shrubs, often also including grasses, herbs, and geophytes.

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.

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] |
Molecular Phylogenetic
Molecular phylogenetics () is the branch of phylogeny that analyzes genetic, hereditary molecular differences, predominantly in DNA sequences, to gain information on an organism's evolutionary relationships. From these analyses, it is possible to determine the processes by which diversity among species has been achieved. The result of a molecular phylogenetic analysis is expressed in a phylogenetic tree. Molecular phylogenetics is one aspect of molecular systematics, a broader term that also includes the use of molecular data in taxonomy and biogeography. Molecular phylogenetics and molecular evolution correlate. Molecular evolution is the process of selective changes (mutations) at a molecular level (genes, proteins, etc.) throughout various branches in the tree of life (evolution). Molecular phylogenetics makes inferences of the evolutionary relationships that arise due to molecular evolution and results in the construction of a phylogenetic tree.
