The San Blas jay (Cyanocorax sanblasianus) is a species of bird in the family Corvidae. It is endemic to Mexico where its natural habitat is subtropical or tropical dry forests; it is a common species and has been rated as "least concern" by the IUCN. [1]
The adult San Blas jay is between 27 and 35 cm (11 and 14 in) long and weighs between 92 and 122 g (3 and 4 oz). The sexes are similar; the adult has back, rump, wings and tail blue and the remaining plumage black. There is a small crest on the front of the head, the bill is black, the irises are white and the legs are black. The juveniles are similar apart from a larger crest, a yellow bill and brown eyes. [2]
This jay is endemic to Mexico. There are two subspecies; C. s. nelsoni is found in southwestern Mexico, from Nayarit, Jalisco and Colima southward to western Guerrero; and C. s. sanblasianus is found in the coastal region of Guerrero. The habitat includes dry and semi-moist woodland, thickets, groves and plantations as well as mangrove areas. This bird is not found deep in the forest. [2] [3]
The species is social, living in small groups of up to thirty individuals including six to ten breeding pairs. These occupy a large territory but have little interaction with neighbouring groups. The birds seem to have stable pair bonds and most start breeding at three years old. The nests are grouped socially in trees, vines or shrubs, often in the crowns of palm trees. Each is constructed of twigs and lined with soft plant material, and a clutch of up to four mottled eggs is laid. Non-breeding females sometimes take short turns at incubation, which takes about eighteen days. Both parents care for the young, and several birds may help feed the chicks, especially after they have fledged. [4] [5]
The San Blas jay is omnivorous, the birds feeding both on the ground and in the lower parts of trees. The diet consists of insects and other invertebrates, fruit and small vertebrates such as lizards. [5] This bird has been observed taking nestlings from the nest of a ruddy ground dove (Columbina talpacoti). [6]
Corvidae is a cosmopolitan family of oscine passerine birds that contains the crows, ravens, rooks, jackdaws, jays, magpies, treepies, choughs, and nutcrackers. In colloquial English, they are known as the crow family, or, in jargon, corvids. Currently 133 species are included in this family. The genus Corvus, including the jackdaws, crows, rooks, and ravens, makes up over a third of the entire family. Corvids are the largest passerines.
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.

The wood thrush is a North American passerine bird. It is closely related to other thrushes such as the American robin and is widely distributed across North America, wintering in Central America and southern Mexico. The wood thrush is the official bird of the District of Columbia.
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".

An Australian endemic, it lives in the monsoon forests and in some drier eucalypt forests.
The purplish-backed jay is a bird of the crow family Corvidae, with purple feathers on its back, wings and tail, and black feathers elsewhere.
