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.

The common yellowthroat, also known as the yellow bandit or Maryland yellow-throat, is a New World warbler. It is an abundant breeder in North America, ranging from southern Canada to central Mexico. The genus name Geothlypis is from Ancient Greek geo, "ground", and thlupis, an unidentified small bird; thlypis is often used in the scientific names of New World warblers.

The mourning warbler is a small songbird of the New World warbler family. Mourning warblers are native to eastern and central North America as well as some countries in Central America. They are neotropical migrants and tend to be found in dense second growth forests. They are under the Wood-warbler category, which consists of arboreal and terrestrial colorful passerines. Wood warblers are in the order Passeriformes, which are perching birds including more than half of all bird species, and the family Parulidae which also includes the Common Yellowthroat, Black and White Warbler, Nashville Warbler, ovenbird, and American Redstart. They are very similar to the MacGillivray's Warbler in appearance, especially in females and immature birds, but their breeding range does not overlap into the west.
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.
