Short-tailed 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.

John Cassin
John Cassin (September 6, 1813 – January 10, 1869) was an American ornithology, ornithologist from Pennsylvania. He worked as curator and vice president at the Philadelphia Academy of Natural Sciences and focused on the systemic classification of the academy's extensive collection of birds. He was one of the founders of the Delaware County Institute of Science and published several books describing 194 new species of birds. Five species of North American birds, a cicada, and a mineral are named in his honor. Early life and education Cassin was born in Upper Providence Township, Delaware County, Pennsylvania, Upper Providence Township, Pennsylvania on September 6, 1813. He was educated at the Westtown School in Westtown Township, Pennsylvania. His great Uncle, John Cassin (naval officer), John Cassin, was a commodore in the U.S. Navy and served in the War of 1812. He served in the Union Army during the American Civil War and was held prisoner in the infamous Confederate Libb ... [...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] |
Emberizidae
The buntings are a group of Old World passerine birds forming the genus ''Emberiza'', the only genus in the family Emberizidae. The family contains 44 species. They are seed-eating birds with stubby, conical bills. Taxonomy The family Emberizidae was formerly much larger and included the species now placed in the Passerellidae (New World sparrows) and Calcariidae (longspurs and snow buntings). Molecular phylogenetic studies found that the large family consisted of distinct clades that were better treated as separate families. The genus ''Emberiza'' is now the only genus placed in the family Emberizidae. The genus was introduced by the Swedish naturalist Carl Linnaeus in 1758 in the tenth edition of his ''Systema Naturae''. The type species was subsequently designated as the yellowhammer (''Emberiza citrinella''). The genus name ''Emberiza'' is from Old German , a bunting. The origin of the English "bunting" is unknown. A 2008 genetic study found that three emberizid species t ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
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 ''Rhopospina'' is a small genus of finch-like tanagers found in grassy areas in Central and South America South America is a continent entirely in the Western Hemisphere and mostly i ...

Tanager
The tanagers (singular ) comprise the bird family (biology), 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 (bird), Habia'' appear to be members of the family Cardinalidae, and have been reassigned to that family by the American Ornithological Society.

Habitat
In ecology, habitat refers to the array of resources, biotic factors that are present in an area, such as to support the survival and reproduction of a particular species. A species' habitat can be seen as the physical manifestation of its ecological niche. Thus "habitat" is a species-specific term, fundamentally different from concepts such as Biophysical environment, environment or vegetation assemblages, for which the term "habitat-type" is more appropriate. The physical factors may include (for example): soil, moisture, range of temperature, and Luminous intensity, light intensity. Biotic index, Biotic factors include the availability of food and the presence or absence of Predation, predators. Every species has particular habitat requirements, habitat generalist species are able to thrive in a wide array of environmental conditions while habitat specialist species require a very limited set of factors to survive. The habitat of a species is not necessarily found in a ge ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Grassland
A grassland is an area where the vegetation is dominance (ecology), dominated by grasses (Poaceae). However, sedge (Cyperaceae) and rush (Juncaceae) can also be found along with variable proportions of legumes such as clover, and other Herbaceous plant, herbs. Grasslands occur naturally on all continents except Antarctica and are found in most ecoregions of the Earth. Furthermore, grasslands are one of the largest biomes on Earth and dominate the landscape worldwide. There are different types of grasslands: natural grasslands, semi-natural grasslands, and agricultural grasslands. They cover 31–69% of the Earth's land area. Definitions Included among the variety of definitions for grasslands are: * "...any plant community, including harvested forages, in which grasses and/or legumes make up the dominant vegetation." * "...terrestrial ecosystems dominated by herbaceous and shrub vegetation, and maintained by fire, grazing, drought and/or freezing temperatures."
