The white-throated sparrow is a passerine bird of the New World sparrow family Passerellidae.
The dark-eyed junco is a species of junco, a group of small, grayish New World sparrows. This bird is common across much of temperate North America and in summer ranges far into the Arctic. It is a very variable species, much like the related fox sparrow, and its systematics are still not completely untangled.
The song sparrow is a medium-sized New World sparrow. Among the native sparrows in North America, it is easily one of the most abundant, variable and adaptable species.
The fox sparrow is a large New World sparrow. It is the only member of the genus Passerella, although some authors split the species into four.
The Savannah sparrow 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, is a well-marked subspecies of the Savannah sparrow, whereas the southwestern large-billed sparrow should be recognized as a distinct species.
Lincoln's sparrow is a small sparrow native to North America. It is a less common passerine bird that often stays hidden under thick ground cover, but can be distinguished by its sweet, wrenlike song. Lincoln's sparrow is one of three species in the genus Melospiza which also includes the song sparrow and the swamp sparrow. It lives in well-covered brushy habitats, often near water. This bird is poorly documented because of its secretive nature and breeding habits solely in boreal regions.
The dickcissel is a small seed-eating migratory bird in the family Cardinalidae. It breeds on the prairie grasslands of the Midwestern United States and winters in Central America, northern Colombia, and northern Venezuela. It is the only member of the genus Spiza, though some sources list another supposedly extinct species.
The black-throated gray warbler or black-throated grey warbler is a passerine bird of the New World warbler family Parulidae. It is 13 cm (5.1 in) long and has gray and white plumage with black markings. The male has the bold black throat of its name, and black stripes on its head, as well as black streaks on its flanks; the female is a paler version of the male, with a white throat and less distinct black markings on the flanks and wings. It breeds in western North America from British Columbia to New Mexico, and winters in Mexico and the southwestern United States. The habitats it prefers are coniferous and mixed forests and scrubland, especially those with pinyon pines, junipers, sagebrush, and oaks. Its nest is an open cup of plant fibers lined with feathers, built a few metres from the ground in the branches of a tree or shrub. Three to five eggs are laid, and young are fed by both parents. Common in its breeding range, it does not seem to be seriously threatened by human activities, unlike many migratory warblers.
The golden-crowned sparrow is a large New World sparrow found in the western part of North America.
The black-chinned sparrow 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 resident. 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 fibers, into which the female lays 2–5 pale blue eggs. The female does most or all of the egg incubation, but both parents feed the hatched nestlings.
The sooty fox sparrow contains the darkest-colored taxa in the genus Passerella. It is currently classified as a "subspecies group" within the fox sparrow pending wider-spread acceptance of species status. It has long been suspected to be a separate evolutionary lineage due to morphological distinctness, and this is confirmed by analysis of mtDNA sequence and haplotype data. This group appears to be most closely related to the thick-billed and/or slate-colored fox sparrows.
The slate-colored fox sparrow group comprises the Rocky Mountain taxa in the genus Passerella. It is currently classified as a "subspecies group" within the fox sparrows pending a more-thorough genetic assay of all forms.
The thick-billed fox sparrow group comprises the peculiarly large-billed Sierra Nevadan taxa in the genus Passerella. It is currently classified as a "subspecies group" within the fox sparrow, pending wider-spread acceptance of its species status.
The olive sparrow is a species of American sparrow in the family Passerellidae. Its range includes Belize, Costa Rica, Guatemala, Honduras, Mexico, Nicaragua and southern Texas.
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.
The saltmarsh sparrow is a small New World sparrow found in salt marshes along the Atlantic coast of the United States. At one time, this bird and the Nelson's sparrow were thought to be a single species, the sharp-tailed sparrow. Because of this, the species was briefly known as the "saltmarsh sharp-tailed sparrow." Saltmarsh sparrow numbers are declining due to habitat loss largely attributed to human activity.
Bell's sparrow is a medium-sized sparrow of the western United States and northwestern Mexico. It used to be placed in the genus Amphispiza, but recent evidence suggested it be placed in its own genus.
The western red-tailed hawk is a subspecies of the red-tailed hawk.
Harlan's hawk or Harlan's red-tailed hawk is a subspecies of the red-tailed hawk.
