Corvidae is a cosmopolitan family of oscine passerine birds that contains the crows, ravens, rooks, magpies, jackdaws, jays, treepies, choughs, and nutcrackers. In colloquial English, they are known as the crow family or corvids. Currently, 139 species are included in this family. The genus Corvus containing 50 species makes up over a third of the entire family. Corvids (ravens) 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, which 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 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.
Cyanocorax is a genus of New World jays, passerine birds in the family Corvidae. It contains several closely related species that primarily are found in wooded habitats, chiefly in lowland tropical rainforest but in some cases also in seasonally dry forest, grassland and montane forest. They occur from Mexico through Central into southern South America, with the green jay and brown jay just entering the United States in southernmost Texas, ad the Azure and Plush-crested jays occurring southwards to the lower Paraná River basin. This genus is considered especially close to Cyanolyca, an upland radiation occurring throughout the American Cordillera from Mexico to Peru and Bolivia, who look very similar to the blue-and-black species of Cyanocorax except for being a bit smaller. The North American blue jay genera Aphelocoma, Cyanocitta and Gymnorhinus seem to be slightly less closely related.
Steller's eider is a migrating Arctic diving duck that breeds along the coastlines of eastern Russia and Alaska. It is the rarest, smallest, and fastest flying of the eider species.
The Canada jay, also known as the grey jay, gray jay, camp robber, or whisky jack, is a passerine bird of the family Corvidae. It is found in boreal forests of North America north to the tree line, and in the Rocky Mountains subalpine zone south to New Mexico and Arizona. A fairly large songbird, the Canada jay has pale grey underparts, darker grey upperparts, and a grey-white head with a darker grey nape. It is one of three members of the genus Perisoreus, a genus more closely related to the magpie genus Cyanopica than to other birds known as jays. The Canada jay itself has nine recognized subspecies.
The scarlet tanager is a medium-sized American songbird. Until recently, it was placed in the tanager family (Thraupidae), but it and other members of its genus are now classified as belonging to the cardinal family (Cardinalidae). The species' plumage and vocalizations are similar to other members of the cardinal family, although the Piranga species lacks the thick conical bill that many cardinals possess. The species resides in thick deciduous woodlands and suburbs.
The gray-crowned rosy finch or gray-crowned rosy-finch is a species of passerine bird in the family Fringillidae native to Alaska, western Canada, and the north-western United States. Due to its remote and rocky alpine habitat it is rarely seen. There are currently six recognized subspecies. It is one of four species of rosy finches.
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 California scrub jay is a species of scrub jay native to western North America. It ranges from southern British Columbia throughout California and western Nevada near Reno to west of the Sierra Nevada. The California scrub jay was once lumped with Woodhouse's scrub jay and collectively called the western scrub jay. The group was also lumped with the island scrub jay and the Florida scrub jay; the taxon was then called simply scrub jay. The California scrub jay is nonmigratory and can be found in urban areas, where it can become tame and will come to bird feeders. While many refer to scrub jays as "blue jays", the blue jay is a different species of bird entirely.
The Yucatan jay is a species of bird in the family Corvidae, the crows and their allies. It is native to the Yucatán Peninsula where its habitats are subtropical or tropical dry forest, plantations and cleared areas at altitudes up to 250 m (820 ft). Adults are about 30 cm (12 in) long, black, with blue wings, mantle, and tail, black bills, yellow eye rings and legs. Immature birds have yellow bills. This is a common species of jay with a wide range and the International Union for Conservation of Nature has rated its conservation status as being of "least concern".
The crested ant tanager is a bird in the family Cardinalidae that is endemic to Colombia. It was formerly placed with the red-crowned ant tanager in the genus Habia.
The Caatinga cacholote is a species of bird in the Furnariinae subfamily of the ovenbird family Furnariidae. It is endemic to Brazil.
Basaseachic Falls National Park is a national park located in the western side of the state of Chihuahua in the heart of the Sierra Madre Occidental mountain range. The park is named after Basaseachic Falls the second tallest waterfall in Mexico with a height of 246 meters (853 ft). Basaseachic Falls empties into Candameña Canyon which was carved by the Basaseachic River over millions of years. The park is known for its pine-oak forest, rock formations, and scenic views from high cliffs. Cliffs in the park reach an impressive height of 1,640 meters (5,380 ft).
The South Central Rockies forests is a temperate coniferous forest ecoregion of the United States located mainly in Wyoming, Idaho, and Montana. It has a considerably drier climate than the North Central Rockies forest.
The colloquial name camp robber is used for several North American species of birds known for their fearlessness around humans and their proclivity for stealing food from campers and picnickers:
The Sierra Madre del Sur pine–oak forests is a subtropical coniferous forest ecoregion in the Sierra Madre del Sur mountain range of southern Mexico.
The pinyon jay is a species of jay, and is the only member of the genus Gymnorhinus. Native to Western North America, the species ranges from central Oregon to northern Baja California, and eastward as far as western Oklahoma, though wanderers are often sighted beyond this range. It is typically found within foothills, especially where pinyon pines occur.
Woodhouse's scrub jay is a species of scrub jay native to western North America, ranging from southeastern Oregon and southern Idaho to central Mexico. Woodhouse's scrub jay was until recently considered the same species as the California scrub jay, and collectively called the western scrub jay. Prior to that both of them were also considered the same species as the island scrub jay and the Florida scrub jay; the taxon was then called simply the scrub jay. Woodhouse's scrub jay is nonmigratory and can be found in urban areas, where it can become tame and will come to bird feeders. While many refer to scrub jays as "blue jays", the blue jay is a different species of bird entirely. Woodhouse's scrub jay is named for the American naturalist and explorer Samuel Washington Woodhouse.
The Colorado Plateau shrublands is an ecoregion of deserts and xeric shrublands in the Western United States.
