The California scrub jay (Aphelocoma californica), is a species of scrub jay native to western North America. It ranges from southern British Columbia throughout California west of the Sierra Nevada. The California scrub jay was once lumped with the island scrub jay, and Woodhouse's scrub jay, collectively called the western scrub jay. The group was also lumped with the Florida scrub jay; the taxon was then called, simply, the scrub jay. The California scrub jay is less ↑

Woodhouse's scrub jay (Aphelocoma woodhouseii), is a species of scrub jay native to western North America. It ranges from southeastern Oregon and southern Idaho to central Mexico. It comprises two distinct subspecies groups. They are Woodhouse's scrub jay (interior US and northern Mexico), and Sumichrast's scrub jay (interior southern Mexico). Woodhouse's scrub jay was once lumped with the California scrub jay, the island scrub jay and collectively called the western scrub jay. It was also lumped less ↑

The American crow (Corvus brachyrhynchos) is a large passerine bird species of the family Corvidae. It is a common bird found throughout much of North America. American crows are the new world counterpart to the carrion crow and the hooded crow. Although the American crow and the hooded crow are very similar in size, structure and behavior, their calls are different. The American crow nevertheless occupies the same role the hooded crow does in Eurasia. less ↑

The common raven (Corvus corax), also known as the northern raven, is a large all-black passerine bird. Found across the Northern Hemisphere, it is the most widely distributed of all corvids. There are at least eight subspecies with little variation in appearance, although recent research has demonstrated significant genetic differences among populations from various regions. It is one of the two largest corvids, alongside the thick-billed raven, and is possibly the heaviest passerine bird; at maturity,... less ↑

The Chihuahuan Raven (Corvus cryptoleucus), is a species of bird in the family Corvidae that is native to the United States and Mexico. It was formerly known as the American White-necked Raven, and has the proportions of a Common Raven with a heavy bill, but is about the same size as a Carrion Crow, or slightly larger than the American Crow (44–51 cm (17–20 in) long). The plumage is all-black with a rich purple-blue gloss in good light.... less ↑

The Blue Jay (Cyanocitta cristata) is a passerine bird in the family Corvidae, native to North America. It is resident through most of eastern and central United States and southern Canada, although western populations may be migratory. It breeds in both deciduous and coniferous forests, and is common near and in residential areas. It is predominately blue with a white chest and underparts, and a blue crest. It has a black, U-shaped collar around its neck... less ↑

The Gray Jay (Perisoreus canadensis), also Grey Jay, Canada Jay or Whiskey Jack, is a member of the crow and jay family (Corvidae) found in the boreal forests across North America north to the tree-line and in subalpine forests of the Rocky Mountains south to New Mexico and Arizona. It is one of three members of the genus Perisoreus, the others being the Siberian Jay, P. infaustus, found from Norway to eastern Russia and the Sichuan... less ↑

Clark's Nutcracker (Nucifraga columbiana), sometimes referred to as Clark's Crow or Woodpecker Crow, is a passerine bird in the family Corvidae. It is slightly smaller than its Eurasian relative the Spotted Nutcracker (N. caryocatactes). It is ashy-grey all over except for the black-and-white wings and central tail feathers (the outer ones are white). The bill, legs and feet are also black. This bird derives its name from the explorer William Clark. less ↑

The pinyon jay (Gymnorhinus cyanocephalus) is a jay between the North American blue jay and the Eurasian jay in size. It is the only member of the genus Gymnorhinus, (monotypic). Its overall proportions are very nutcracker-like and indeed this can be seen as convergent evolution as both birds fill similar ecological niches. The pinyon jay is a bluish-grey coloured bird with deeper head colouring and whitish throat with black bill, legs and feet. less ↑
