The following is a list of all currently recognized species within the passerine bird genus Corvus (the crows and ravens).
Listed alphabetically. [1] [2]
The taxonomy of the C. antecorax/C. fossilis complex as well as the C. pliocaenus/C. betfianus/C. praecorax/C. simionescui, in particular the temporal succession and relationship to the living relatives, is not yet fully resolved. At least some of these "species" seem to have been direct ancestors of the living forms as listed above.
Formerly, some authorities also considered the following species as species within the genus Corvus:
A raven is any of several larger-bodied passerine bird species in the genus Corvus. These species do not form a single taxonomic group within the genus. There is no consistent distinction between crows and ravens. Names are assigned to different species chiefly based on their size.
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, 135 species are included in this family. The genus Corvus containing 47 species makes up over a third of the entire family. Corvids (ravens) are the largest passerines.
The carrion crow is a passerine bird of the family Corvidae, native to western Europe and the eastern Palearctic.
The hooded crow, also called the scald-crow or hoodie, is a Eurasian bird species in the genus Corvus. Widely distributed, it is found across Northern, Eastern, and Southeastern Europe, as well as parts of the Middle East. It is an ashy grey bird with black head, throat, wings, tail, and thigh feathers, as well as a black bill, eyes, and feet. Like other corvids, it is an omnivorous and opportunistic forager and feeder.
The Australian raven is a passerine corvid bird native to Australia. Measuring 46–53 centimetres (18–21 in) in length, it has an all-black plumage, beak and mouth, as well as strong, greyish-black legs and feet. The upperparts of its body are glossy, with a purple-blue, greenish sheen; its black feathers have grey bases. The Australian raven is distinguished from the Australian crow, and other related corvids, by its long chest feathers, or throat hackles, which are prominent in mature birds. Older individuals and subadults have white irises, while the younger birds' eyes display blue inner rims; hatchlings and young birds have brown, dark irises until about fifteen months of age, at which point their irises become hazel-coloured, with an inner blue rim around each pupil, this lasting until they are roughly 2.5 to 3 years of age. Nicholas Aylward Vigors and Thomas Horsfield described the Australian raven in 1827, its species name coronoides highlighting its similarity with the carrion crow. Two subspecies are recognised, which differ slightly in their vocalisations, and are quite divergent, genetically.
The Torresian crow, also called the Australian crow or Papuan crow, is a passerine bird in the crow family native to the north and west of Australia and nearby islands in Indonesia and Papua New Guinea. The species has a black plumage, beak and mouth with white irises. The base of the feathers on the head and neck are white. The Torresian crow is slightly larger with a more robust bill than the morphologically similar little crow.
The American crow 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 of Eurasia; they all occupy the same ecological niche. Although the American crow and the hooded crow are very similar in size, structure and behavior, their calls and visual appearance are different.
Pica is a genus of seven species of birds in the family Corvidae in both the New World and the Old. It is one of several corvid genera whose members are known as magpies.
There are two species of passerine birds commonly called chough that constitute the genus Pyrrhocorax of the Corvidae (crow) family of birds. These are the red-billed chough, and the Alpine chough. The white-winged chough of Australia, despite its name, is not a true chough but rather a member of the family Corcoracidae and only distantly related.
The common raven is a large all-black passerine bird. It is the most widely distributed of all corvids, found across the Northern Hemisphere. It is a raven known by many names at the subspecies level; 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, the common raven averages 63 centimetres in length and 1.47 kilograms in mass. Although their typical lifespan is considerably shorter, common ravens can live more than 23 years in the wild. Young birds may travel in flocks but later mate for life, with each mated pair defending a territory.
Ostriches are large flightless birds. Two living species are recognised, the common ostrich, native to large areas of sub-Saharan Africa, and the Somali ostrich, native to the Horn of Africa.
A crow is a bird of the genus Corvus, or more broadly, a synonym for all of Corvus. The word "crow" is used as part of the common name of many species. The related term "raven" is not linked scientifically to any certain trait but is rather a general grouping for larger-sized species of Corvus.
The New Zealand raven was native to New Zealand, but has been extinct since the 16th century. There were three subspecies: the North Island raven, South Island raven, and Chatham raven from the Chatham Islands.
The Somali crow, or dwarf raven, is approximately the size of the carrion crow, Corvus corone but with a longer bill and a somewhat more brownish cast to the feathers, especially when worn.
The Petralona Cave a karst formation, is located at 300 m (984 ft) above sea-level on the western foot of Mount Katsika, about 1 km (0.62 mi) east of the village of Petralona, about 35 km (22 mi) south-east of Thessaloniki city on the Chalkidiki peninsula, Greece. The site came to public attention when in 1960 a fossilized archaic human skull was found. The cave had been discovered accidentally only a year earlier (1959) after erosion had left clefts in the rock. "Bejeweled" with impressive stalactite and stalagmite formations and holding an abundance of fossils, the cave soon attracted geologists and paleontologists. After decades of excavations the cave is open to the public and scientific work is documented and presented in an adjacent archaeological museum.
The eastern carrion crow is a member of the crow family and a subspecies of the carrion crow. Differences from the nominate subspecies include a larger size, at a length about 500 millimetres (20 in), and more graduated outer tail feathers. The eastern carrion crow is found in Siberia from the Yenisei to Japan, south to Central Asia, Afghanistan, Eastern Iran, Kashmir, Tibet and northern China. They generally lay three to five eggs in trees or buildings. The eggs show no difference from the nominate subspecies.
The robust crow or slender-billed crow was a species of large, raven-sized crow that was endemic to the islands of Oahu and Molokai in the Hawaiian Islands during the Holocene. C. viriosus was frugivorous and was adapted for this with a long, slender bill. It was pushed to extinction due to the arrival of people and pests like rats.
