The carrion crow is a passerine bird of the family Corvidae and the genus Corvus which is native to western Europe and the eastern Palearctic.
The Australian raven is a passerine bird in the genus Corvus native to much of southern and northeastern Australia. Measuring 46–53 centimetres (18–21 in) in length, it has all-black plumage, beak and mouth, as well as strong grey-black legs and feet. The upperparts are glossy, with a purple, blue, or green sheen, and its black feathers have grey bases. The Australian raven is distinguished from the Australian crow species by its throat hackles, which are prominent in adult birds. Older adult individuals have white irises, younger adults have white irises with an inner blue rim, while younger birds have dark brown irises until fifteen months of age, and hazel irises with an inner blue rim around each pupil until age two years and ten months. 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 recognized, which differ slightly in calls 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 little raven is a species of the family Corvidae that is native to southeastern Australia. An adult individual is about 48–50 cm (19–19.5 in) in length, with completely black plumage, beak, and legs; as with all Australian species of Corvus, the black feathers have a grey base, and the iris of the adult bird is white . Although the little raven was first named by Gregory Mathews in 1912, it was only in 1967 that there was consensus to separate it from the Australian raven as a distinct species.
The pied crow is a widely distributed African bird species in the crow genus of the family Corvidae.
The house crow, also known as the Indian, greynecked, Ceylon or Colombo crow, is a common bird of the crow family that is of Asian origin but now found in many parts of the world, where they arrived assisted by shipping. It is between the jackdaw and the carrion crow in size but is slimmer than either. The forehead, crown, throat and upper breast are a richly glossed black, whilst the neck and breast are a lighter grey-brown in colour. The wings, tail and legs are black. There are regional variations in the thickness of the bill and the depth of colour in areas of the plumage.
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.
The white-necked raven is a species of raven native to eastern and southern Africa. It is somewhat smaller than the common raven or its nearest relative, the thick-billed raven C. crassirostris.
The collared crow, also known as the ring-necked crow or white-collared crow, is a member of the family Corvidae native to China and north of Vietnam.
The fish crow is a species of crow associated with wetland habitats in the eastern and southeastern United States.
The Tamaulipas crow is a crow found in northeastern Mexico and southern Texas.
The fan-tailed raven is a passerine bird of the crow family native to Eastern Africa and the Arabian Peninsula.
The brown-necked raven is a larger bird than the carrion crow though not as large as the common raven. It has similar proportions to the common raven but the bill is not so large or deep and the wings tend to be a little more pointed in profile. The head and throat are a distinct brownish-black giving the bird its English name, while the rest of the plumage is black glossed with purple, blue or purplish-blue. Like the common raven, thick-billed raven and white-necked raven, it is one of the larger raven species. The feathers of this species often fade quite quickly to a brownish black and the bird can look distinctly brown by the time it moults. The feet, legs and bill are black. The dwarf raven was formerly considered a subspecies but this bird now appears to be closer to the pied crow than this species.
The large-billed crow, formerly referred to widely as the jungle crow, is a widespread Asian species of crow. It is very adaptable and is able to survive on a wide range of food sources, making it capable of colonizing new areas, due to which it is often considered a nuisance, especially on islands. It has a large bill, which is the source of its scientific name macrorhynchos and it is sometimes known by the common name thick-billed crow. It can also be mistaken for a common raven. Johann Georg Wagler first described the species from a holotype obtained from Java in the year 1827. The eastern jungle crow and Indian jungle crow were once considered conspecific and together called the jungle crow.
The Jamaican crow is a comparatively small corvid. It shares several key morphological features with two other West Indian species, the Cuban crow and the white-necked crow of Hispaniola, which are very closely related to it.
The white-necked crow is the largest of the four Caribbean corvids. It is endemic to the island of Hispaniola ; it was formerly also extant on Puerto Rico, but has been extirpated there due to considerable forest clearance and hunting.
The gray crow, formerly known as the bare-faced crow, is about the same size as the Eurasian carrion crow but has somewhat different proportions and quite atypical feather pigmentation during the juvenile phase for a member of this genus.
The white-billed crow is a member of the crow family found on the Solomon Islands.
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 species of Corvus.
The palm crow is a relatively small corvid that occurs on the Caribbean island of Hispaniola and Cuba, where it was formerly very frequent, but is now reduced in population.
