The dwarf jay (Cyanolyca nanus) is a species of bird in the family Corvidae. It is endemic to Mexico. Its natural habitat is subtropical or tropical moist montane forests. As its name would imply, this is the smallest member of the family Corvidae at 20–23 cm long and weighing 41 g. It is threatened by habitat loss.

The Benito Juárez National Park is in the Valles Centrales Region of Oaxaca, Mexico, and includes parts of the municipalities of San Felipe Tejalapam and San Andres Huayapan.
The southern boundary of the park is about 5 kilometers north of the City of Oaxaca.
The park was established in 1937 during the presidency of General Lazaro Cardenas del Rio, and is named after President Benito Juárez, who was a native of Oaxaca.C. nana

Corvidae is a cosmopolitan family of oscine passerine birds that contains the crows, ravens, rooks, jackdaws, jays, magpies, treepies, choughs, and nutcrackers. In common English, they are known as the crow family, or, more technically, corvids. Over 120 species are described. The genus Corvus, including the jackdaws, crows, rooks, and ravens, makes up over a third of the entire family.
Corvids display remarkable intelligence for animals of their size and are among the most intelligent birds thus far studied. Specifically, members of the family have demonstrated self-awareness in mirror tests (European magpies) and tool-making ability (e.g., crows and rooks), skills which until recently were thought to be possessed only by humans and a few other higher mammals. Their total brain-to-body mass ratio is equal to that of non-human great apes and cetaceans, and only slightly lower than that of humans.They are medium to large in size, with strong feet and bills, rictal bristles, and a single moult each year (most passerines moult twice). Corvids are found worldwide except for the tip of South America and the polar ice caps. The majority of the species are found in tropical South and Central America, southern Asia and Eurasia, with fewer than 10 species each in Africa and Australasia. The genus Corvus has re-entered Australia in relatively recent geological prehistory, with five species and one subspecies there. Several species of raven have reached oceanic islands, and some of these species are now highly threatened with extinction or have already become extinct.Crypsirina
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 racket-tailed treepie, formerly placed in Dendrocitta, is an all-black Southeast Asian species. The grey and black hooded treepie is endemic to Myanmar.Cyanocitta
Cyanocitta is a genus of birds in the family Corvidae, a family which contains the crows, jays and magpies. Established by Hugh Edwin Strickland in 1845, it contains the following species:
The name Cyanocitta is a combination of the Greek words kuanos, meaning "dark blue" and kitta, meaning "jay".Cyanolyca
Cyanolyca is a genus of small jays found in humid highland forests in southern Mexico, Central America and the Andes in South America. All are largely blue and have a black mask. They also possess black bills and legs and are skulking birds. They frequently join mixed-species flocks of birds.Cyanopica
Cyanopica is a genus of magpie in the family Corvidae. They belong to a common lineage with the genus Perisoreus.Daurian jackdaw
The Daurian jackdaw (Coloeus dauuricus) is a bird in the crow family, Corvidae. It is closely related to the western jackdaw. The name derives from the Dauria region of eastern Russia.Flores crow
The Flores crow (Corvus florensis) is a species of bird in the family Corvidae.
It is endemic to Indonesia.
Its natural habitats are subtropical or tropical dry forest and subtropical or tropical moist lowland forest.
It is threatened by habitat loss.Garrulus
Garrulus is a genus of Old World jays, passerine birds in the family Corvidae.Ground jay
The ground jays or ground choughs belong to a distinct group of the passerine order of birds in the genus Podoces of the crow family Corvidae. They inhabit high altitude semi-desert areas from central Asia to Mongolia.
Ground jays show adaptations to ground living such as long, strong legs adapted to fast running and the ability to leap and bound onto boulders and rocks with great agility. Their long, curved thick bills are adapted for digging and probing.
While capable of flight (which they do infrequently and relatively weakly), they prefer running, and will readily perch on trees and bushes also.Jay
Jays are several species of medium-sized, usually colorful and noisy, passerine birds in the crow family, Corvidae. The names jay and magpie are somewhat interchangeable, and the evolutionary relationships are rather complex. For example, the Eurasian magpie seems more closely related to the Eurasian jay than to the East Asian blue and green magpies, whereas the blue jay is not closely related to either.Little crow (bird)
The little crow (Corvus bennetti) is an Australian species of crow, very similar to the Torresian crow in having white bases to the neck and head feathers (shown when ruffled in strong wind) but slightly smaller (38–45 cm in length) and with a slightly smaller bill. It has the same white iris that distinguish the Australian species from all other Corvus except a few island species to the north of Australia, and one from Eurasia, the jackdaw (Corvus monedula). Like the Australian raven, this species has a blue ring around the pupil.Magpie
Magpies are birds of the Corvidae (crow) family. The black and white Eurasian magpie is widely considered one of the most intelligent animals in the world and one of only a few non-mammal species able to recognize itself in a mirror test. In addition to other members of the genus Pica, corvids considered as magpies are in the genera Cissa.
Magpies of the genus Pica are generally found in temperate regions of Europe, Asia and western North America, with populations also present in Tibet and high elevation areas of India, i.e. Ladakh (Kargil and Leh) and Pakistan. Magpies of the genus Cyanopica are found in East Asia and also the Iberian peninsula. The birds called magpies in Australia are not related to the magpies in the rest of the world (see Australian magpie).Magpie-jay
The magpie-jays are a genus, Calocitta, of the family Corvidae (crow-like birds) native to the southern part of North America. Sometimes placed in the genus Cyanocorax. The two known species are known to form hybrids.Nutcracker (bird)
The nutcrackers (Nucifraga) are a genus of three species of passerine bird, in the family Corvidae, related to the jays and crows.
The genus Nucifraga was introduced by the French zoologist Mathurin Jacques Brisson in 1760 with the spotted nutcracker (Nucifraga caryocatactes) as the type species. The genus name is a New Latin translation of German Nussbrecher, "nut-breaker".Treepie
The treepies comprise four closely related genera (Dendrocitta, Crypsirina, Temnurus and Platysmurus) of long-tailed passerine birds in the family Corvidae. There are 11 species of treepie. Treepies are similar to magpies. Most treepies are black, white, gray or brown. They are found in Southeast Asia. They live in tropical forests. They are highly arboreal and rarely come to the ground to feed.Urocissa
Urocissa is a genus of birds in the family Corvidae, a family which contains the crows, jays and magpies. Established by Jean Cabanis in 1850, it contains the following species:
Urocissa is a combination of the Greek words for "tail" (oura) and "magpie" (kissa).
