Corvidae is a cosmopolitan family of oscine passerine birds that contains the crows, ravens, rooks, jackdaws, jays, treepies, choughs, and nutcrackers. In colloquial English, they are known as the crow family or corvids. Currently, 133 species are included in this family. The genus Corvus, including the crows, rooks, and ravens, makes up over a third of the entire family. Corvids (ravens) are the largest passerines.
The Eurasian jay is a species of passerine bird in the crow family Corvidae. It has pinkish brown plumage with a black stripe on each side of a whitish throat, a bright blue panel on the upper wing and a black tail. The Eurasian jay is a woodland bird that occurs over a vast region from western Europe and north-west Africa to the Indian subcontinent and further to the eastern seaboard of Asia and down into south-east Asia. Across this vast range, several distinct racial forms have evolved which look different from each other, especially when comparing forms at the extremes of its range.
Garrulus is a genus of Old World jays, passerine birds in the family Corvidae.
The blue jay is a passerine bird in the family Corvidae, native to eastern North America. It lives in most of the eastern and central United States; some eastern populations may be migratory. Resident populations are also in Newfoundland, Canada; breeding populations are found across southern Canada. It breeds in both deciduous and coniferous forests, and is common in residential areas. Its coloration is predominantly blue, with a white chest and underparts, and a blue crest; it has a black, U-shaped collar around its neck and a black border behind the crest. Males and females are similar in size and plumage, and plumage does not vary throughout the year. Four subspecies have been recognized.
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 also known as the long-crested jay, mountain jay, and pine jay. 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.
Urocissa is a genus of birds in the Corvidae, a family that contains the crows, jays, and magpies.

Dendrocitta is a genus of long-tailed passerine birds in the crow and jay family, Corvidae. They are resident in tropical South and Southeast Asia. The generic name is derived from the Greek words dendron, meaning "tree," and kitta, meaning "magpie".
Crypsirina is a small genus of long-tailed passerine birds in the crow and jay family, Corvidae. The two species are highly arboreal and rarely come to the ground to feed. The generic name is derived from the Greek words kruptō, meaning "to conceal," and rhis or rhinos, meaning "nostrils".
Cyanocorax is a genus of New World jays, passerine birds in the family Corvidae. The generic name is derived from the Greek words κυανος (kuanos), meaning "dark blue," and κοραξ (korax), meaning "raven".

The Mexican jay formerly known as the gray-breasted jay, is a New World jay native to the Sierra Madre Oriental, Sierra Madre Occidental, and Central Plateau of Mexico and parts of the southwestern United States. In May 2011, the American Ornithologists' Union voted to split the Mexican jay into two species, one retaining the common name Mexican jay and one called the Transvolcanic jay. The Mexican jay is a medium-sized jay with blue upper parts and pale gray underparts. It resembles the Woodhouse's scrub-jay, but has an unstreaked throat and breast. It feeds largely on acorns and pine nuts, but includes many other plant and animal foods in its diet. It has a cooperative breeding system where the parents are assisted by other birds to raise their young. This is a common species with a wide range and the International Union for Conservation of Nature has rated its conservation status as being of "least concern".
The typical honeycreepers form a genus Cyanerpes of small birds in the tanager family Thraupidae. They are found in the tropical New World from Mexico south to Brazil. They occur in the forest canopy, and, as the name implies, they are specialist nectar feeders with long curved bills.
