Passerculus
''Passerculus'' is a genus of birds that belongs to the New World sparrow family Passerellidae. While formerly considered to include just the Savannah sparrow (''P. sandwichensis''), recent studies by Birdlife International indicate 3 Savannah sparrow subspecies should promoted to separated species, as result, that there 4 species in the genus. Species found in this genus include: * Savannah sparrow The Savannah sparrow (''Passerculus sandwichensis'') is a small New World sparrow. It was the only member of the genus '' Passerculus'' and is typically the only widely accepted member.

Savannah Sparrow
The Savannah sparrow (''Passerculus sandwichensis'') is a small New World sparrow. It was the only member of the genus '' Passerculus'' and is typically the only widely accepted member. Comparison of mtDNA NADH dehydrogenase subunit 2 and 3 sequences indicates that the Ipswich sparrow, formerly usually considered a valid species (as ''Passerculus princeps''), is a well-marked subspecies of the Savannah sparrow, whereas the southwestern large-billed sparrow should be recognized as a distinct species (''Passerculus rostratus''). The species name ''sandwichensis'' is Latin, of place, Sandwich, Unalaska, or Aleutians area, from which came the first subspecies, Aleutian Savannah sparrow, to be described. The common name honors Savannah, Georgia where Alexander Wilson discovered the species in 1811. Distribution This passerine bird breeds in Alaska, Canada, northern, central and Pacific coastal United States, Mexico and Guatemala. The Pacific and Mexican breeders are resident, but oth ...

American Sparrow
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 ...

Charles Lucien Bonaparte
Charles Lucien Jules Laurent Bonaparte, 2nd Prince of Canino and Musignano (24 May 1803 – 29 July 1857), was a French naturalist and ornithologist. Lucien and his wife had twelve children, including Cardinal Lucien Bonaparte. Life and career Bonaparte was the son of Lucien Bonaparte and Alexandrine de Bleschamp. Lucien was a younger brother of Napoleon I, making Charles the emperor’s nephew. Born in Paris, he was raised in Italy. On 29 June 1822, he married his cousin, Zénaïde, in Brussels. Soon after the marriage, the couple left for Philadelphia in the United States to live with Zénaïde's father, Joseph Bonaparte (who was also the paternal uncle of Charles). Before leaving Italy, Charles had already discovered a warbler new to science, the moustached warbler, and on the voyage he collected specimens of a new storm-petrel. On arrival in the United States, he presented a paper on this new bird, which was later named after Alexander Wilson. Bonaparte then set about ...

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 ...
