Yellow-browed Sparrow
The yellow-browed sparrow (''Ammodramus aurifrons'') is a species of bird in the family Passerellidae. First described by Johann Baptist von Spix in 1825, this American sparrow is found across much of the Amazon basin in South America. Its natural habitats are subtropical or tropical moist shrubland, pastureland, and heavily degraded former forest. Taxonomy When Johann Baptist von Spix first described the yellow-browed sparrow in 1825, he put it in the now-defunct genus ''Tanagra'', believing it to be a tanager. The classification error was soon recognized, and the species was moved first to the genus ''Ammodramus'', then to ''Myospiza''—a genus Robert Ridgway created in 1898 for this and the closely related grassland sparrow. Most taxonomists now subsume ''Myospiza'' into ''Ammodramus''. DNA analysis indicates that the yellow-browed sparrow is a sister species to the grassland sparrow, and that these two species make a sister group with the grasshopper sparrow; these ...

Bird Genera
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. Bi ...

Kansas
Kansas () is a state in the Midwestern United States. Its capital is Topeka, and its largest city is Wichita. Kansas is a landlocked state bordered by Nebraska to the north; Missouri to the east; Oklahoma to the south; and Colorado to the west. Kansas is named after the Kansas River, which in turn was named after the Kansa Native Americans who lived along its banks. The tribe's name (natively ') is often said to mean "people of the (south) wind" although this was probably not the term's original meaning. For thousands of years, what is now Kansas was home to numerous and diverse Native American tribes. Tribes in the eastern part of the state generally lived in villages along the river valleys. Tribes in the western part of the state were semi-nomadic and hunted large herds of bison. The first Euro-American settlement in Kansas occurred in 1827 at Fort Leavenworth. The pace of settlement accelerated in the 1850s, in the midst of political wars over the slavery debate. Wh ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Late Miocene
The Late Miocene (also known as Upper Miocene) is a sub-epoch of the Miocene epoch (geology), Epoch made up of two faunal stage, stages. The Tortonian and Messinian stages comprise the Late Miocene sub-epoch, which lasted from 11.63 Ma (million years ago) to 5.333 Ma. The evolution of life The gibbons (family Hylobatidae) and orangutans (genus ''Pongo'') are the first groups to split from the line leading to the hominins, including humans, then gorillas (genus ''Gorilla''), and finally, chimpanzees and bonobos (genus ''Pan (genus), Pan''). The splitting date between hominin and chimpanzee lineages is placed by some between 4 to 8 million years ago, that is, during the Late Miocene.

Grassland Sparrow
The grassland sparrow (''Ammodramus humeralis'') is a species of bird in the family Passerellidae. It is found in Argentina, Bolivia, Brazil, Colombia, French Guiana, Guyana, Paraguay, Peru, Suriname, Uruguay, and Venezuela. Its natural habitats are dry savannah, subtropical or tropical seasonally wet or flooded lowland grassland, and pastureland. Description The grassland sparrow is a robust species with a large head and a short tail, with a total length of about . The wings are short and the legs fairly long. The upper parts are brownish-grey streaked with black. The breast and flanks are greyish-buff or pinkish-buff and the underparts are dull white.

Grasshopper Sparrow
The grasshopper sparrow (''Ammodramus savannarum'') is a small New World sparrow. It belongs to the genus ''Ammodramus,'' which contains three species that inhabit grasslands and prairies. Although sometimes found in crop fields and they will readily colonize reclaimed grassland. In the core of their range, grasshopper sparrows are dependent upon large areas of grassland where they avoid trees and shrubs. They seek out heterogenous patches of prairie that contain clumps of dead grass or other vegetation where they conceal their nest, and also contain barer ground where they forage for insects (especially grasshoppers), spiders, and seeds. Grasshopper sparrows are unusual among New World sparrows in that they sing two distinct song types, the prevalence of which varies with nesting cycle. The primary male song, a high trill preceded by a stereotyped series of short chips, is reminiscent of the sounds of grasshoppers and is the origin of this species' name. Like some other birds of t ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
American Ornithological Society
The American Ornithological Society (AOS) is an ornithological organization based in the United States. The society was formed in October 2016 by the merger of the American Ornithologists' Union (AOU) and the Cooper Ornithological Society. Its members are primarily professional ornithologists, although membership is open to anyone with an interest in birds. The society publishes the two scholarly journals, ''The Auk'' and '' The Condor'' as well as the ''AOS Checklist of North American Birds''. In 2013, the American Ornithologists' Union announced a close partnership with the Cooper Ornithological Society, including joint meetings, a centralized publishing office, and a refocusing of their respective journals to increase efficiency of research. In October 2016, the AOU announced that it was ceasing to operate as an independent union and was merging with the Cooper Ornithological Society to create the American Ornithological Society.
