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 ...

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 ...

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. There is a narrow white eye-ring, and a spot of yellow on the lores and another on the bend of the wing. The song is a high-pitched but thin series of plaintive phrases, "eee, telee, teeeee". This bird is similar in appearance to the yellow-browed sparrow, but that has more yellow on the face and the voice is quite distinct. ...

American Sparrows
New World sparrows are a group of mainly New World passerine birds, forming the family Passerellidae. They are seed-eating birds with conical bills, brown or gray in color, and many species have distinctive head patterns. Although they share the name sparrow, New World sparrows are more closely related to Old World buntings than they are to the Old World sparrows (family Passeridae). New World sparrows are also similar in both appearance and habit to finches, with which they sometimes used to be classified. Taxonomy The genera now assigned to the family Passerellidae were previously included with the buntings in the family Emberizidae. A phylogenetic analysis of nuclear and mitochondrial DNA sequences published in 2015 found that the Passerellidae formed a monophyletic group that had an uncertain relationship to the Emberizidae. Emberizidae was therefore split and the family Passerellidae resurrected. It had originally been introduced, as the subfamily Passerellinae, by the Ge ...

Pair Bond
In biology, a pair bond is the strong affinity that develops in some species between a mating pair, often leading to the production and rearing of offspring and potentially a lifelong bond. Pair-bonding is a term coined in the 1940s that is frequently used in sociobiology and evolutionary biology circles. The term often implies either a lifelong socially monogamous relationship or a stage of mating interaction in socially monogamous species. It is sometimes used in reference to human relationships. Varieties According to evolutionary psychologists David P. Barash and Judith Lipton, from their 2001 book ''The Myth of Monogamy'', there are several varieties of pair bonds: *''Short-term pair-bond:'' a transient mating or associations *''Long-term pair-bond:'' bonded for a significant portion of the life cycle of that pair *''Lifelong pair-bond:'' mated for life *''Social pair-bond:'' attachments for territorial or social reasons *''Clandestine pair-bond:'' quick extra-pair copulat ...
