Spizella
The genus ''Spizella'' is a group of American sparrows in the family Passerellidae. These birds are fairly small and slim, with short bills, round heads and long wings. They are usually found in semi-open areas, and outside of the nesting season they often forage in small mixed flocks. Systematics This genus was formerly placed with the Old World buntings in the family Emberizidae. However, genetic studies revealed that New World sparrows formed a distinct clade and thus it was placed in the resurrected family Passerellidae.

Chipping Sparrow
The chipping sparrow (''Spizella passerina'') is a species of New World sparrow, a passerine bird in the family Passerellidae. It is widespread, fairly tame, and common across most of its North American range. The chipping sparrow has five subspecies. This bird is a partial migrant with northerly populations flying southwards in the fall to overwinter in Mexico and the southern United States, and flying northward again in spring. It molts twice a year. In its breeding plumage it has orangish-rust upper parts, gray head and underparts and a distinctive reddish cap. In non-breeding plumage, the cap is brown and the facial markings are less distinct. The song is a trill and the bird has a piercing flight call that can be heard while it is migrating at night. In the winter, Chipping Sparrows are gregarious and form flocks, sometimes associating with other bird species. They mostly forage on the ground for seeds and other food items, as well as clambering on plants and trees, fe ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Brewer's Sparrow
Brewer's sparrow (''Spizella breweri'') is a small, slim species of American sparrow in the family Passerellidae. This bird was named after the ornithologist Thomas Mayo Brewer. Description and systematics Adults have grey-brown backs and speckled brown crowns, both with dark streaks, and a pale eye-ring. Their wings are brown with light wing bars and the underparts are pale grey. Their bill is pale with a dark tip and they have a long notched tail.

Black-chinned Sparrow
The black-chinned sparrow (''Spizella atrogularis'') is a small bird in the genus '' Spizella'', in the New World sparrow family Passerellidae. It is found in the southwestern United States and throughout much of Mexico north of the Isthmus of Tehuantepec; most populations in the US migrate south after breeding while those in Mexico are . It is a slim, long-tailed bird, primarily gray with a reddish-brown back streaked with black, brown wings and tail, a pink beak, and brownish legs and feet. In the breeding season, the male shows black on his throat, chin, and the front of his face. Females, youngsters and nonbreeding males show little or no black in these areas. An unobtrusive bird, it spends much of its time foraging slowly along the ground, either alone or in small groups, sometimes mixing with other ''Spizella'' species. It is an omnivore, feeding primarily on seeds during the winter and insects during the summer. It builds a cup-shaped nest of grasses, rootlets, or plant fi ...

American Tree Sparrow
The American tree sparrow (''Spizelloides arborea''), also known as the winter sparrow, is a medium-sized New World sparrow. Taxonomy In 2014, the American tree sparrow was moved to its own monotypic genus, ''Spizelloides'', from genus ''Spizella'', based on polyphyly in ''Spizella'' and multilocus molecular evidence suggesting the species was strongly divergent from other extant genera. Description The bird's measurements are as follows: * Length: 5.5 in (14 cm) * Weight: 0.5–1.0 oz (13–28 g) * Wingspan: 9.4 in (24 cm) Adults have a rusty cap and grey underparts with a small dark spot on the breast. They have a rusty back with lighter stripes, brown wings with white bars and a slim tail. Their face is grey with a rusty line through the eye. Their flanks are splashed with light brown. They are similar in appearance to the chipping sparrow. Distribution and habitat Their breeding habitat is tundra or the northern limits of the boreal forest in Alaska an ...

Field Sparrow
The field sparrow (''Spizella pusilla'') is a small New World sparrow in the family Passerellidae. It is about long and weighs about . The head is grey with a rust-coloured crown, white eye-ring and pink bill. The upper parts are brown streaked with black and buff, the breast is buff, the belly is white and the tail is forked. There are two different colour morphs, one being greyer and the other more rufous. The field sparrow is distributed across eastern Canada and the eastern United States, with northern populations migrating southwards to southern United States and north-eastern Mexico in the fall. The typical habitat of this bird is bushy country with shrubs and grassland. The nest is a cup-shaped construction built on the ground and hidden beneath a bush or clump of grass. The birds forage on the ground or in low vegetation, feeding mainly on seeds and insects. The population is thought to be in slow decline, but it is a common species with a wide range, and the Intern ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Worthen's Sparrow
Worthen's sparrow (''Spizella wortheni'') is a species of American sparrow that is endemic to northeastern Mexico. It was first described by Robert Ridgway in 1884 and named for the American naturalist Charles K. Worthen. This small bird has been listed as endangered by the IUCN since 1994. Description ''Spizella wortheni'' can range in length from 12.5 to 14 cm. It is identifiable by its distinctive head pattern. It has a grey head with a rufous crown, a brown postocular stripe and a pink bill. It has grey-brown upperparts, with dark brown streaks. It has a grey bottom, and dark brown wings and tail. Its wings are "edged paler, with broad whitish to pale buff wing-bar, buffy-rufous tertial and secondary edging, and greyish lesser coverts".

The song is a dry, chipping trill of 2–3 seconds duration and is describe ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Timberline Sparrow
The timberline sparrow (''Spizella breweri taverneri'') is a taxonomically controversial American sparrow. Usually treated as a subspecies of Brewer's sparrow, it is considered a distinct species ''Spizella taverneri'' by some authorities. While the timberline sparrow recognizably differs in some details, there is little reproductive isolation between the taxa. When it was still considered a species, it was listed as being of least concern by the IUCN The International Union for Conservation of Nature (IUCN) is an international organization working in the field of nature conservation and sustainable use of natural resources. Founded in 1948, IUCN has become the global authority on the status ....E.g. Baillie ''et al.'' (2004). Footnotes References * (2004): ''2004 IUCN Red List of Threatened Species.

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 Ger ...

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 ornithology, ornithologist, and a nephew of Napoleon. Lucien and his wife had twelve children, including Cardinal Lucien Bonaparte (cardinal), Lucien Bonaparte. Life and career Bonaparte was the son of Lucien Bonaparte and Alexandrine de Bleschamp.

On 29 June 1822, he married his cousin, Zénaïde Laetitia Julie Bonaparte, 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 Old World warbler, warbler new to science, the moustached warbler, and on the voyage he collected specimens of a new Wilson's storm-petrel ...
