Steller's jay is a bird native to western North America and the mountains of Central America, closely related to the blue jay found in eastern North America. It is the only crested jay west of the Rocky Mountains. It is also sometimes colloquially called a "blue jay" in the Pacific Northwest, but is distinct from the blue jay of eastern North America. The species inhabits pine-oak and coniferous forests.

The dark-eyed junco is a species of junco, a group of small, grayish New World sparrows. The species is common across much of temperate North America and in summer it ranges far into the Arctic. It is a variable species, much like the related fox sparrow, and its systematics are still not completely resolved.
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.

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.
LeConte's sparrow, also known as LeConte's bunting, is one of the smallest New World sparrow species in North America.
Robert Ridgway was an American ornithologist specializing in systematics. He was appointed in 1880 by Spencer Fullerton Baird, secretary of the Smithsonian Institution, to be the first full-time curator of birds at the United States National Museum, a title he held until his death. In 1883, he helped found the American Ornithologists' Union, where he served as officer and journal editor. Ridgway was an outstanding descriptive taxonomist, capping his life work with The Birds of North and Middle America. In his lifetime, he was unmatched in the number of North American bird species that he described for science. As technical illustrator, Ridgway used his own paintings and outline drawings to complement his writing. He also published two books that systematized color names for describing birds, A Nomenclature of Colors for Naturalists (1886) and Color Standards and Color Nomenclature (1912). Ornithologists all over the world continue to cite Ridgway's color studies and books.
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.

Despite its name, it is not a true finch, but now recognized as a member of the tanager family (Thraupidae), after being long placed in the Emberizidae. It is the only member of the genus Acanthidops. The scientific name commemorates the American ornithologist Spencer Fullerton Baird.
